Meyer, Tour, and Lennox Have a Playdate

Fri, 11 Sep 2026 00:43:38 -0000

It's time to mock some Christian apologist clowns peddling creationist propaganda! And today we have not one, not two, but three scoops of idiot frauds to sink our teeth into. Those are Stephen Meyer, James Tour, and John Lennox. They visited the illustrious "think tank" Hoover Institution to spew some of their never-changing script of lies in support of Meyer's big propaganda theatrical release that flopped its way into select cinemas last month. Let's make fun of all the dumb things they say!

Present Tense for Third Conjugation Verbs in Latin

Thu, 10 Sep 2026 23:56:00 -0000

We've looked at first and second conjugation verbs in Latin. Now it's time to check out the third conjugation, starting with the present tense. This conjugation is very tough, but don't get discouraged! We will take it slow.

Will Synthetic Vitamins Make Me Explode?

Thu, 10 Sep 2026 23:40:54 -0000

This was my final submission for the American Chemical Society's ChemChamps contest in 2015.

The words natural and synthetic are thrown around a lot these days, when talking about foods, medicine, and other things. But what do they really mean, and how are they different? Is one necessarily better than the other? Can the bioactivity of a molecule depend on its pathway? Let's answer these questions and more.

Thu, 10 Sep 2026 21:35:27 -0000

How do we represent an atom, with all of its protons, neutrons, and electrons? With nuclide symbols, of course! These show the type of element, as well as the atomic number, mass number, and electrical charge of an atom. That's all you need to know!

Cardinal Numbers in Latin

Thu, 10 Sep 2026 20:32:43 -0000

Let's learn how to count in Latin! This will require that we learn the cardinal numbers, also sometimes called the Arabic numeral system. This can get a little weird because some numbers decline while others are invariable, and it's not very intuitive which ones they are. But there's nothing to do but go through them, so let's get started!

History of Atomic Theory

Thu, 10 Sep 2026 19:30:00 -0000

We all know that atoms exist. But we didn't always! A lot of people contributed in different ways to help develop our current understanding of atomic structure, starting all the way back in Ancient Greece. Grab some popcorn and let Professor Dave tell you the story!

The Cell Cycle and its Regulation

Thu, 10 Sep 2026 17:56:00 -0000

Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad. Luckily, cells obey something called the cell cycle, which is regulated by a variety of signaling molecules, which tell the cell when to divide and when to chill out. Let's look at the phases of this cycle and some of its regulatory mechanisms now.

Avi Loeb's Alien Grift is Crumbling

Thu, 10 Sep 2026 17:27:16 -0000

Remember Avi Loeb? The Harvard astronomer turned pointless grifter who never shuts up about how everything is aliens? He's up to his old tricks again! He's making garbage YouTube content, he's knee deep in UAP psyop slop from the White House, and most importantly, he's whining a whole lot about me! That's right, he saw my first two videos exposing him for the worthless fraud that he is, and he's not too happy about it. Let's jump back into Avi's world for a bit!

Scientific Notation and Dimensional Analysis

Thu, 10 Sep 2026 16:24:32 -0000

In science, sometimes we have to talk about very large and very small numbers. We need a special way to do this called scientific notation. We also need a way to convert between different units of measurement. I know, I know, you hate math. But it's really easy math, and Professor Dave will help make it even easier!

Explaining to Godfrey Why Moon Landing Denial is Silly

Remember when I went on Godfrey's podcast to humiliate flat earther Lord Jamar? And then the other time when I went on there to explain a bunch of basic science for fun? Now it's time for something in between. Godfrey and his guests were espousing moon landing denial in a recent episode. Dante invited me on the show to debunk their talking points and explain some more science. It was a fun productive time, check it out!

Sabine Hossenfelder Joins the Eric Weinstein Damage Control Parade

Thu, 10 Sep 2026 11:56:00 -0000

At this point it is common knowledge that Eric Weinstein is a pointless fraud paid by Peter Thiel to spew propaganda all over the internet. As so many of us have long suspected, Sabine Hossenfelder is exactly that as well. This was made abundantly clear when Sabine recently joined the Eric Weinstein damage control parade after his embarrassing encounter with Sean Carroll on Piers Morgan, and then my video with Christian Ferko even further exposing GU as absolutely nothing and the details of his Perimeter Institute visit. But just in case that wasn't enough to convince you, allow me to take you through some of her other very recent content to demonstrate how her disgusting rhetoric is 100% aligned with Eric's script and Thiel's agenda.

How do we say that somebody got fifth in the race, or won first prize in a contest? Ordinal numbers! Let's learn them now.

Talking With a Former Creationist Pastor I Helped Deconvert

Thu, 10 Sep 2026 09:05:27 -0000

Timmy Gibson is a former pastor. He used to be the precise kind of person I debunk, denying evolution, repeating anti-vaccine propaganda, and passing on this ideology to his congregation. But over the past few years he has seen the light, and is now a science-minded atheist! He even says that my content was a crucial part of his deconversion. Let's talk about his journey, my content, and some of the silly things he used to believe!

Natural vs. Synthetic Vitamins

Thu, 10 Sep 2026 05:57:16 -0000

Anti-science mentality is prevalent in modern society. This is evidenced most clearly in a complete distrust of chemicals synthesized in a laboratory. But does the activity of a molecule depend whatsoever on the pathway from which it formed? Let's see why not.

We just learned how to add and subtract polynomials, so now we have to learn how to multiply them. This is a little tricky at first, but once we master the FOIL method, it's easy as pie!

Dan Richards is Completely Obsessed With Me (So is Danny Jones)

Thu, 10 Sep 2026 04:54:32 -0000

It's time to dunk on Sasquatch Taint some more! This idiot has been running his mouth about how badly he wants to "debate" me, since that's the only way he can pretend to remain relevant. Also, Danny Jones has decided to pull a Joe Rogan and slander me regularly, so let's make fun of him some more too, along with another one of his idiot guests, Kurt Metzger. How the hell did the internet get so infested with the dumbest people alive? Let's do some spring cleaning.

Cyclohexane Chairs

Thu, 10 Sep 2026 03:51:49 -0000

Cyclohexane makes weird shapes! The most important is the chair conformation. Here we will learn how to draw cyclohexane chairs, how to flip them, the difference in energy between the two chair conformations, and between axial and equatorial substituents. Chairs are easy place to lose points on exams if you don't draw them just right!

Comparing Vertebrates and Invertebrates

Wed, 09 Sep 2026 23:56:00 -0000

Now that we have wrapped up the invertebrate chordates, it's time to tackle the third and by the far the largest subphylum of Chordata, Vertebrata. So what is a vertebrate? By contrast, what is an invertebrate? What do these terms mean in the context of phylogeny? Let's make sure this is well understood before examining the vertebrates.

EPA Head Lee Zeldin is a Freaking Nightmare

Wed, 09 Sep 2026 15:21:49 -0000

Trump's second-term cabinet is the stuff of nightmares. I've talked about Bobby Kennedy's dismantling of HHS quite a bit, but it's not just public health that is in shambles under this administration. The environment is on the chopping block as well, especially under new EPA head Lee Zeldin. The person who is supposed to be in charge of protecting the citizenry by preventing the private sector from polluting our air and water is actively siding with the polluters and making sure they have all the freedom to pollute as much as they want. It's difficult to describe how much of a worthless cretin this guy is, but let's give it a shot.

Michael Button: Rising Pseudoarcheology Fraud

Wed, 09 Sep 2026 09:05:27 -0000

It's time to expose another worthless pseudoarcheology fraud! With some obvious targets out of the way, let's hit one of the newer rising stars, Michael Button. He's essentially a Graham Hancock clone. Same script full of lies, same accent, same demeanor, same everything. He seems to be hoping to be passed the torch, and Graham seems to approve. If you saw through toxic douchebags like Dan and Jimmy, but you were clinging to this guy as some kind of voice for truth, think again. Every video is jam packed with lies and deception. Let's debunk the crap out of his content, as well as his Joe Rogan episode.

Nucleophiles, Electrophiles, Leaving Groups, and the SN2 Reaction

Wed, 09 Sep 2026 03:51:49 -0000

This is it! The start of the very scary reaction mechanisms! Take it easy, chief. First we will define nucleophiles, electrophiles, and leaving groups. Then, we will examine the mechanism, transition state, and stereospecificity of the SN2 reaction. Push those electrons!

Adjectives of the Third Declension in Latin

Wed, 09 Sep 2026 02:49:05 -0000

We've learned the easier adjectives of the first class, which follow the first and second declensions, but there are many adjectives that follow the third declension. This group is a little more complex, and they can be divided into three different subgroups depending on how many terminations they have. Let's take a look!

Ortho/Meta/Para Directors

Wed, 09 Sep 2026 01:46:21 -0000

What's this ortho/meta/para business you've been hearing so much about? Why is benzene ruining your life? Don't worry, 16 minutes or so from now it will all make sense. From directing groups to activating and deactivating groups. It has to do with electron donating groups and electron withdrawing groups.

Exposing Discovery Institute Part 10: Casey Luskin Again (Because He's Such a Loser Fraud)

Tue, 08 Sep 2026 23:56:00 -0000

How did I let a whole year slip by without dumping on the douchebags at Discovery Institute? It's time to get this playlist going again, and we're going to start with that complete asshat who kicked off this series, Casey Luskin. He's been lying even more than usual lately, about junk DNA and comparative genomics. Watch me eviscerate his propaganda surrounding a recent paper, including exposing his deceptive editing of a figure and other assorted shenanigans, all to pretend that science disproves human/chimp common ancestry. Will these assholes ever learn their lesson?

Destiny Loves Genocide

Tue, 08 Sep 2026 14:19:05 -0000

After mentioning Israel's genocide numerous times in other content regarding Christian theocrats, Peter Thiel's puppets, or figures like Avi Loeb, many people have asked to me to just go ahead and make a long-form video about my views on Israel. I had avoided this since I'm a science communicator and prefer not to make exclusively political content, but after a twerp named Destiny took it upon himself to call me a Nazi, I had an excuse to do it. So here it is. Israel is objectively committing genocide, Zionism is the vile ideology behind it, and here is everything you need to hear to understand exactly what Israel is, and why they are an existential threat to all of humanity.

Introduction to the Apollo Program

Tue, 08 Sep 2026 12:13:38 -0000

One of the most spectacular achievements of the 20th century was the series of moon landings performed by NASA's Apollo Program. These occurred between 1969 and 1972. What is the story of the program that put humans on the lunar surface for the first time? Let's go through all the details, with the help of extremely rare archival footage that will captivate you! This first video will serve as an overview for the entire program, describing all of the vehicles and equipment involved, some important contextual information regarding the establishment of the program, as well as the chronology of Apollo 1 through Apollo 6, including the devastating Apollo 1 fire that tragically claimed the lives of three astronauts.

Cahn-Ingold-Prelog Convention (Determining R/S)

Tue, 08 Sep 2026 09:05:27 -0000

In this clip, the Cahn-Ingold-Prelog Convention is introduced, to allow for assignment of absolute configuration of stereocenters. I dunno why it took three dudes to make the convention, but it's pretty sweet if you think about it.

Apollo 7: The First Manned Apollo Mission

Tue, 08 Sep 2026 03:51:49 -0000

With a general overview of the Apollo program complete, and with Apollo 1-6 covered, it's time to get to some real action. Apollo 7 was the first manned Apollo mission. It took Wally Schirra, Donn Eisele, and Walter Cunningham up into Low Earth Orbit for a 10-day shakedown cruise, where they tested many features of the spacecraft. While the mission was a great success, a bit of drama did ensue, so let's learn all about it!

Anthony Fauci is Evil Satan Bastard Man!

Tue, 08 Sep 2026 01:46:21 -0000

Anthony Fauci is a horrible demon man who eats babies and should be in jail! That's what I've been hearing from most of the public, anyway. Why are they saying that, though? What did he really do? As it turns out, he upheld real science in the face of state-sanctioned pseudoscience all throughout a pandemic that killed millions of people. For defying the state, his reward has been the most monumental smear campaign of a public servant in recent history. SARS-CoV-2 did not leak from a lab, Fauci never did anything but make science-based recommendations to save as many lives as possible, and if you didn't know that, you fell for propaganda from the government. Watch this video and get on the right side of history.

The Passive Voice in Latin

Mon, 07 Sep 2026 23:40:54 -0000

Up until this point we have been learning everything in the active voice. This would be something llike: "The dog chewed the bone". But there is also the passive voice, which would turn that sentence into "The bone was chewed by the dog." This is used quite a bit in Latin for various reasons, so we need to know how to use it!

I Found the Most Insane Creationist Propaganda of All Time

You have never seen creationist propaganda like this. There's a guy that's supposed to be like an Indiana Jones type dude, there's a kid who's supposed to be like Marty McFly and the Doc combined into one character, and there's a robot dinosaur who eats popcorn and pukes and does impressions. Nobody could write parody like this if they tried. The crappy dialogue and acting, the worst editing imaginable, and the most laughable attempt at indoctrinating children ever conjured by a human mind. Watch along and laugh with me.

Everything Is Crumbling For Destiny (And Pangburn)

Mon, 07 Sep 2026 10:08:10 -0000

Last month I put out a video demonstrating conclusively that Israel has been committing genocide against Palestinians for nearly three years. At the same time I exposed the streamer Destiny (Steven Bonnell II) as a genocide-denying sexual predator and total loser, since he called me a neo-Nazi, and I used that as my excuse to do the Israel video. He and his cult of loser orbiters had a complete meltdown about it, which was expected, so now that the damage control is over, it's time to clap back and even further expose Destiny. His lies about genocide, as well as all of his super creepy sex stuff involving minors and violation of consent. Let's also spend some time on Travis Pangburn, who unexpectedly transformed himself into a Zionist propaganda mill shouting "antisemitism" every ten seconds to come to Destiny's defense, which was equal parts surprising and hilarious. This one slaps, so buckle up.

Oxidation and Reduction

Mon, 07 Sep 2026 09:05:27 -0000

This is different from the redox we knew from general chemistry. It's not so much about highlighting electron transfer as it is about the number of bonds to oxygen that an atom possesses. An oxidation increases a carbon's bonds to oxygen, a reduction reduces a carbon's bonds to oxygen. Makes sense, no? Let's look at some common oxidizing and reducing agents while we're at it.

Ablative of Agent (Ablativus Auctoris)

Mon, 07 Sep 2026 08:02:43 -0000

When converting sentences in the active voice into passive voice, we will be turning the subject of the sentence into the personal agent. In order to do this, we need to use something called the ablative of agent. Let's learn how to do that now.

Solving Algebraic Equations With Roots and Exponents

Now that we can simplify expressions with roots and exponents, we can pretty easily solve equations that contain them, too. We still are just undoing operations that the variable is participating in, we just have to take square roots instead of adding and subtracting. Give it a try, you'll do great!

Apollo 8: First Humans Around the Moon

Mon, 07 Sep 2026 03:51:49 -0000

After the success of Apollo 7, all eyes were on the moon, and sending astronauts into lunar orbit. But the decision to do this in the mission immediately following Apollo 7 was a bold and risky move, based on the perceived status of the Soviet space program, which ultimately paid off. Apollo 8 sent astronauts Frank Borman, Jim Lovell, and Bill Anders all the way to the moon, the first humans to ever get so far away from Earth. They orbited the moon ten times, gathering an enormous amount of data to inform the selection of future landing sites, and then returned home safely. The famous photo "Earthrise" was taken on this mission, along with many other incredible images of the Earth from deep space, the first such images ever collected.

Sabine Hossenfelder: More Exposed Than Ever! (Racism Edition)

Mon, 07 Sep 2026 01:46:21 -0000

Sabine is back! Your favorite salty German anti-science propaganda peddling fraud is in the spotlight again. This time, she's not just badmouthing academics and glazing the oligarchy, she's outing herself as fully racist! Legitimately, completely racist. It's absolutely glorious to behold. But don't worry, there's still lots of anti-science propaganda and pro-oligarchy slop to cover, since we haven't checked in with her in over a year. So let's expose her as racist and then mock some of her more recent content. Hooray!

Avi Loeb is a Fraud Now

Sun, 06 Sep 2026 23:56:00 -0000

Avi Loeb is a Harvard astronomer turned pseudoscience-peddling fraud. Since 2017 he's been spewing horseshit about how everything is aliens when it definitely isn't, just to sell a bunch of books to credulous laypeople. Predictably, when the scientific community politely pushes back on his bullshit, he throws a toddler tantrum. I wonder what will happen if someone exposes him in a not so polite manner? Let's find out.

Prokaryotic cells were simple enough, but eukaryotic cells are much more complex! They have so many more little features and compartments, like the deluxe model of your car. We have to learn about every single one of these organelles and other components before we move on to other areas of biology, so let's take a tour of the eukaryotic cell, starting with animal cells!

It's finally time to cover Ancient Greece! This civilization is one of the first that people think of when they imagine the ancient world. But prior to the ever-popular figures of Classical Greece, there were earlier civilizations, those being the Minoans and the Mycenaeans. What were they all about? Let's find out!

Simplifying Expressions With Roots and Exponents

Sun, 06 Sep 2026 05:56:00 -0000

Now we have all these pesky terms with exponents and roots, and they come in all these complicated looking expressions. Square this, cube root that, whatever will we do? Don't worry, it's usually pretty easy to simplify these until they get into a more palatable form, and it's quite satisfying to get them there! Let's learn all the tricks.

Astronomer Meir Schochet (Get to Know a Scientist!)

Sat, 05 Sep 2026 23:56:00 -0000

As far as the sciences go, astronomy is as old as it gets! We've been looking at the stars in an empirical manner for millennia. How do we approach observation astronomy today? With incredible telescopes of course, but what are we looking for and what do we do with the data? Let Meir tell you all about it!

Square Roots, Cube Roots, and Other Roots

Sat, 05 Sep 2026 17:56:00 -0000

What are these funny little symbols? They're roots! Taking the square root of something give you the number that, when squared, gives the original number. Cube roots are the same, but they are the opposite of cubing. I'm not explaining it very well right now, but that's what this clip is for, so watch it!

Solving Algebraic Inequalities

Fri, 04 Sep 2026 17:56:00 -0000

We've seen lots of equations, which are constructs that equate two things, but there are also inequalities, which state that two things are not equal, but rather that one is greater than or less than the other. We can solve this just like equations, but there are one or two little differences that we have to go over. Check it out!

Prokaryotic Cells: The Simplest Kind of Life

Fri, 04 Sep 2026 05:56:00 -0000

We've established that the basic unit of life is the cell, and that the simplest forms of life are just one cell. The earliest unicellular organisms were prokaryotic, and there are many prokaryotic organisms still around today, including all bacteria. So let's go over the features of the prokaryotic cell!

Once all the evidence from a crime scene has been collected and analyzed, it's time for crime scene reconstruction. This is where the investigator tries to piece together an account of the events which occurred at the crime scene. This is highly complex and empirical, so let's discuss some of the details now.

The Origin of Life on Earth

Tue, 01 Sep 2026 05:56:00 -0000

You must have wondered about it before, haven't you? How did life begin on earth? I mean the very first thing. The first unicellular organism, billions of years ago. Is it even possible? As it happens, our understanding of chemistry, biochemistry, and biology has become so sophisticated over the years, that we now have a pretty reasonable grasp as to how abiogenesis must have occurred. This is the spontaneous generation of life from non-living material. As incredible as it sounds, there is a lot of science to discuss here, so let's get into it!

Basic Number Properties for Algebra

Sun, 30 Aug 2026 17:56:00 -0000

Before we dive into solving all kinds of equations, we want to just quickly go over some number properties and how they will apply to algebraic expressions just like they did for arithmetic ones. Most of these will be familiar, like the commutative and associative properties, as well as the distributive property, but they will become even more important in algebra. We also go over a few other basic ones that are completely intuitive, but still worth mentioning. Take a look!

Introduction to Algebra: Using Variables

Sun, 30 Aug 2026 05:56:00 -0000

When we learn math in school, for a while it's just called math, but then one day around 8th grade, it's suddenly called algebra, and every math class after that has a special name, too. But don't worry, it's not so scary! It's just a new set of symbols and algorithms to become familiar with. But don't forget that at one point you had learn the plus and minus symbols and what those meant. Soon, algebra will be just as easy as arithmetic! I promise.

Expert Testimony

Sat, 29 Aug 2026 23:56:00 -0000

After all of the forensic analysis that goes into a case, the culmination of this process is expert testimony provided in court. This is where forensic scientists present the evidence they have collected, which may incriminate or exonerate a defendant. Who can be an expert? How do they conduct themselves in court? Let's talk about all of this!

Will Artificial Intelligence Destroy Humanity?

Sat, 29 Aug 2026 11:56:00 -0000

With ChatGPT, Grok, Claude, and so many other models, AI, or artificial intelligence, is on the rise. It's everywhere, and it will only become more ubiquitous with time. What does this mean for humans? Beyond the economic concerns of AI replacing many or even most jobs, is AI a threat to human survival? Many scholars say that AI is an existential threat on the level of climate change or nuclear war. Why do they think this and what can we do about it? Is the AI industry doing anything about it? In this piece we will go over all of these questions and more, so watch as though our lives depend on it, because they might!

Analyzing Sets of Data: Range, Mean, Median, and Mode

Sat, 29 Aug 2026 05:56:00 -0000

What does the word "average" mean to you? There are a lot ways we use that word, and even in math, it can imply a few different things. If we want to summarize a set of data in a meaningful way, we can talk about the mean, the median, or the mode, and one might be more useful than another in a particular context. So let's learn what these are all about!

With ordinary differential equations wrapped up, it's time to move on the partial differential equations. These can be trickier than ODEs, but don't worry, we will learn all kinds of handy techniques for solving them. Let's start out simply by going over the basics regarding classification of PDEs, and introducing differential operators.

Multiplication and Division of Fractions

Fri, 28 Aug 2026 05:56:00 -0000

If we know how to add and subtract fractions, we should know how to multiply and divide them too, right? Don't worry, it's actually even easier than adding and subtracting them, because when we multiply two fractions, they don't have to have the same denominator, like when we add them. And dividing by a fraction is the same as multiplying by its reciprocal. It's all in here, take a look!

Matt Ridley is Lying to You About Climate Change

Wed, 26 Aug 2026 23:56:00 -0000

Go to https://consensus.app/ for a new way to search through primary scientific literature!

It's finally time to tackle climate change denial. There are so many frauds peddling disinformation in this realm, so who should we tackle? The answer is Matt Ridley. He is the poster boy for "lukewarmism", which is a version of climate change denial that accepts some science surrounding this topic but denies other science, which makes it very dangerous, since it appears rational and science-based to the untrained ear. It's kind of like intelligent design, if young earth creationism is equivalent to an outright denial that global warming is happening at all. Matt is a super rich coal man who peddles a well-crafted script of lies regarding anthropogenic global warming, the amount of warming that has occurred, the amount that is projected to occur, and how dangerous it is. Let's get way into the weeds and debunk all of his claims as thoroughly as humanly possible, so that everyone will be equipped to combat this propaganda wherever they find it.

Greatest Common Factor (GCF)

Wed, 26 Aug 2026 05:56:00 -0000

We learned a neat trick for how to quickly get the least common multiple of two numbers, so let's find a similarly easy way to find the greatest common factor of two numbers. Again it involves prime factorization, which of course everyone enjoys.

Ancient Greece Part 3: Hellenistic Greece (300 – 50 BCE)

Tue, 25 Aug 2026 23:56:00 -0000

While many people consider only Classical Greece, the Hellenistic period that followed was no less eventful or influential. This was the era in which Macedonia came to dominate the Greek mainland, and Alexander the Great conquered a huge empire spanning all the way to India. How was this Hellenistic empire governed, and by whom? Let's take a look!

Least Common Multiple (LCM)

Tue, 25 Aug 2026 17:56:00 -0000

Being able to find the least common multiple of two numbers is very useful, as it will allow us to add and subtract fractions, and do all kinds of other cool things. One way is to list all the multiples and look at the lists, but this gets tricky as numbers get bigger, so learn a neat trick for how to do this quickly!

Anticoagulants: Types and Mechanism of Action

Tue, 25 Aug 2026 11:56:00 -0000

With anti-platelets covered, it's time to look at a related class of drugs, anticoagulants. These also influence blood clot generation but through different pathways. These target the generation of fibrin and thrombin from their precursors, fibrinogen and prothrombin. This will require learning about the very complicated clotting factor cascade, so let's get to it!

James Madison: Father of the Constitution (1809 - 1817)

Tue, 25 Aug 2026 05:56:00 -0000

James Madison was a tiny fellow, but he packed a political punch. He was absolutely pivotal in the drafting of both the Constitution and the Bill of Rights, and he started the Democratic-Republican Party with Thomas Jefferson, all before becoming president in 1809. We wrap up a lot of the early history of the United States in this clip, so take a look!

Eric Weinstein Doesn't Understand Economics

Mon, 24 Aug 2026 23:56:00 -0000

Everyone knows by now that when Eric Weinstein pretends to be a genius physicist, he's actually just a grifting fraud posturing for science illiterate laypeople to manipulate them with propaganda. But did you know that he tries to do the same thing with economics? It's true, he pretends that he and his wife have revolutionized the field, but nobody will acknowledge them because they're stupid buttfaces. Well unfortunately for him, just like how physicists did eventually read Geometric Unity and explain how it's literally nothing, economists have caught wind of his claims regarding economics, and are now doing the same thing there too. One such economist, Matthijs van Veelen, joins me in this video to help us understand how Eric has no clue what he's talking about in this field. Enjoy!

Divisibility, Prime Numbers, and Prime Factorization

Mon, 24 Aug 2026 17:56:00 -0000

Now that we understand division, we can talk about divisibility. A number is divisible by another if their quotient is a whole number. The smaller number is a factor of the larger one, but are there numbers with no factors at all? There's some pretty surprising stuff in this one!

Laplace’s Equation: Separation of Variables

Mon, 24 Aug 2026 11:56:00 -0000

After looking at first-order partial differential equations, it's time to move on to second order PDEs. One method for solving these is to use Laplace's equation. This will allow us to separate the variables. Let's see how it works!

Order of Arithmetic Operations: PEMDAS

Mon, 24 Aug 2026 05:56:00 -0000

Sometimes there are expressions that contain a number of different arithmetic operations. But how do we evaluate these? Left to right? Right to left? Does it matter? Someone make a decision! Well, someone did, and we have a strict algorithm that tells us the order in which we evaluate arithmetic expressions. It's an acronym, and acronyms are fun, so this will be fun!

Earlier this year, I humiliated a rapping flat earther named Lord Jamar, lived on a podcast. Since then, he's been completely obsessed with me, refusing to admit that he's a complete buffoon who fell for the dumbest hoax in human history, but instead doubling down on everything and venting about what a stupid shill I am to whomever will listen. So let's react to him doing that!

Negative Numbers

Sun, 23 Aug 2026 05:56:00 -0000

We figured out how to use numbers a long time ago, but then the concept of negative numbers came about. This is a much more abstract concept, because you can't have a negative amount of apples, or something like that. Nevertheless, negative numbers are ubiquitous in math, so we had better learn all about them!

You've seen me debunk flat earthers many times before, but here's a twist! Watch me do it with one of the flat earthers I used to debunk! Jeran Campanella, formerly of the Globebusters, saw the light in Antarctica and is no longer a flat earther. Now he gears his content towards debunking flat earth and other similar conspiracy theories, which is a good thing. Watch us mock your favorite flat earth buffoons together!

It seems like it's been forever since we've dunked on James Tour, the lying creationist fraud who rages against origin of life research because it hurts his feelings. But he's been mouthing off quite a bit lately, so it's time to dunk on him harder than ever before! Remember how I make fun of James all the time for never having the balls to try and publish his lies in a peer-reviewed journal? Well it looks like he's done exactly that! Or no, not exactly. But he's pretending it's what he did. So as usual, let's tear his bullshit to smithereens and humiliate him something awful, shall we?

Bret Weinstein Refused to Debate Me on Piers Morgan

Thu, 20 Aug 2026 23:56:00 -0000

Check out https://www.strawberry.me/professordave to get started with your career coach today!

So I went on Piers Morgan recently to explain to Piers how RFK Jr. is a massive fraud who should be yanked from office immediately. I was supposed to debate Bret Weinstein about this, but the little wiener declined. Why do you suppose that might be? Oh right, because he knows he's a lying douchebag, and that I would humiliate him. But he can't stop me from making a video demolishing all the dumb things he said in his part of the segment. So let's do that!

Tylenol is the Cause of Autism! (According to Trump and RFK Jr.)

Thu, 20 Aug 2026 11:56:00 -0000

Today on "What the Fuck is Reality Anymore?" we discuss the White House press conference from Monday in which Trump and RFK Jr. announced that Tylenol is the cause of autism. Tylenol. Autism. I know it sounds crazy, but Trump, Bobby, Jay Bhattacharya, Marty Makary, and Dr. Oz are here to explain all the details! With a crack squad of supergeniuses like this, who totally aren't lying pieces of shit at all, what could go wrong?

Working With Percentages

Thu, 20 Aug 2026 05:56:00 -0000

Oh my! There's a big sale at your favorite store! 30% off, in fact! But wait, what does that mean exactly? Percentages are convenient ways of conveying magnitude by comparing some value to one hundred. Why a hundred? Because it's not too big and not too small. Let's learn how to work with these babies.

Decimals: Notation and Operations

Wed, 19 Aug 2026 17:56:00 -0000

We just learned that we can use place values to represent any number towards the infinitely large, but what about the infinitely small? What about the teeny tiny fractions of one? For that, we need decimal places. It's pretty simple, so check it out!

Explaining to Piers Morgan Why RFK Jr. Sucks

Wed, 19 Aug 2026 11:56:00 -0000

Many people watched my video detailing what I would have said to Bret Weinstein the grifting fraud if he had the courage to debate me on Piers Morgan. But so many people asked me to upload my part of the segment as well, so I decided to do that too. Fingers crossed I don't get a takedown request, hope you like it!

Large Whole Numbers: Place Values and Estimating

Wed, 19 Aug 2026 05:56:00 -0000

So there are a lot of numbers. An infinite number, in fact. So how can we possibly have a symbol for every single possible amount of objects? Well we don't need to, because of place values. With these, we can use just ten symbols and represent every number imaginable. Check it out!

Understanding Fractions, Improper Fractions, and Mixed Numbers

Tue, 18 Aug 2026 17:56:00 -0000

Once we know how to divide, we must learn about fractions, because not all divisions will lead to whole number quotients. But there are proper fractions, improper fractions, mixed numbers... what are all these things? Just check this out!

James Tour Farts Out Some More Apologetics

Tue, 18 Aug 2026 11:56:00 -0000

James Tour just doesn't know how to quit when he's incredibly far behind! He kept his nose down for a little while after our debate and some embarrassing events that immediately followed, but this year he's been mouthing off relentlessly as though I'm not here to crap all over him like I always do. Today let's cover a particularly disgusting recent video that attempts to slander me, and completely misrepresent origin of life researcher Ram Krishnamurthy, all to try and save some face on just a few things he got humiliated about during our debate. Luckily I'm here to restore context, show you what he won't, and demonstrate that just like always, James is nothing more than a lying idiot fraud.

Thomas Jefferson: Author of the Declaration of Independence (1801-1809)

Tue, 18 Aug 2026 05:56:00 -0000

Thomas Jefferson was quite an interesting fellow. He was definitely a genius, as he was an expert in pretty much everything you could be an expert of. He was a great writer, too. But there is a little of hypocrisy in there for good measure, so watch this if you want to know more about the mind of Thomas Jefferson, one of the most interesting figures in American History.

The History of Fingerprints

Mon, 17 Aug 2026 23:56:00 -0000

Everybody knows that detectives look for fingerprints at the scene of a crime. But how was this practice developed? When did we figure out what fingerprints are, and begin to use them in forensics? Who are the people that helped develop this knowledge? It's a very interesting story, so let's check it out!

Multiplication and Division of Small Numbers

Mon, 17 Aug 2026 17:56:00 -0000

What came next after addition and subtraction? Why, multiplication and division, of course! Multiplication is kind of like addition, really. In fact, it's just repeated addition. Take a look at this early innovation in arithmetic, and the properties associated with these operations.

Fourier Series and Transforms Part 2: Power Spectra and K-Space

Mon, 17 Aug 2026 11:56:00 -0000

We just learned about Fourier series and Fourier transforms, so now let's put them together and learn about some applications. What is spectral density? How can we use Fourier transforms to classify linear second-order partial differential equations as elliptic, parabolic, or hyperbolic? Where do these concepts show up in modern technology? Let's find out!

Addition and Subtraction of Small Numbers

Mon, 17 Aug 2026 05:56:00 -0000

Alright, so we've decided to learn all of the maths, but where shall we start? Well, let's start at the beginning. The first kind of math we developed was simple arithmetic. We needed this at the dawn of civilization to communicate very simple ideas. Most of us can add small numbers together easily, but is there any more we can say about these operations?

Introduction to Mathematics

Sun, 16 Aug 2026 17:56:00 -0000

Everyone hates math, right? Wrong! I like math. Mathematicians like math, presumably. Physicists like math, usually. People who hate math just don't understand it. But like that weird ethnic food you're scared of trying, or that odd kid in class that doesn't say much, if you come to understand something it's not so scary. In fact, if we can learn enough about math, we will come to love it, because there is so much we can do with it. Watch this series to supplement your math classes, or just to learn enough math that you can become friends. It starts out super easy so don't be afraid! Okay, let's go!

With the cartilaginous fish covered, let's move on to the bony fish, Osteichthyes. This is split up into Actinopterygii and Sarcopterygii. The first of these clades is very large, containing most of the species that we refer to as "fish", so it will take some time to describe. Let's start by learning about their anatomy.

So I traveled to New York City for a live debate against prominent anti-vaxxers and douchebags supreme, Steve Kirsch and Pierre Kory. Given that they have profited off of human life, nobody in the history of my channel deserves to be exposed more, and I got to do it right to their dumb grifter faces. Aiding me in this endeavor was Dr. Dan Wilson of Debunk the Funk. Between the two of us, these jerks didn't know what hit them, so sit back and enjoy the carnage.

James Tour Just Keeps Getting Dumber (For Jesus!)

Fri, 14 Aug 2026 11:56:00 -0000

If you've watched James Tour whine about origin of life research, you know he's dumber than rocks. But did you know that he's been getting dumber and dumber by the month? He's said so many dumb things in lectures and interviews over the past year that I just had to make a video mining all of his recent content for the funniest moments. Let's laugh at him harder than ever!

Calculating Percent Error

Fri, 14 Aug 2026 05:56:00 -0000

Sometimes we take measurements, and sometimes we're off by a little bit. How far off? Does it make sense to just use a number? Shouldn't we use something that tells us how far off we are relative to the true value? Yes we should, hence, percent error. Take a look and I'll show you what I mean.

Converting Between Temperature Scales (Celsius, Fahrenheit, and Kelvin)

Thu, 13 Aug 2026 17:56:00 -0000

If you're American, you're familiar with the Fahrenheit scale, so 30 degrees is cold and 100 degrees is hot. But in the rest of the world, nobody uses this scale! They use Celsius, and to them, 30 is pretty darn hot. Furthermore, scientists use Kelvin, and to them, 30 is so cold it would kill you dead! We'd better learn how to convert between this different temperature scales, don't you think?

Thu, 13 Aug 2026 05:56:00 -0000

Alright guys, you've been asking a lot of questions by email and in the comments section, and not all of them are about science. So I decided to start a playlist where I can respond to these queries, however bizarre they may be! The obvious choice for the first installment in this series was to address the wide variety of speculation surrounding my appearance and ethnic background. What am I? Indian? Arab? Armenian? You'll have to watch this clip to find out!

Today's episode exposing Discovery Institute frauds focuses on Michael Egnor! He's a brain surgeon who has no idea how brains work. Mikey tells a lot of dumb lies about brains in order to pretend that souls exist, and that science somehow supports their existence. Shall we debunk the shit out of his dumb lies about neuroscience and further expose this toxic propaganda mill in the process? Of course we shall!

Quantum Electrodynamics (QED)

Mon, 10 Aug 2026 05:56:00 -0000

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's why it's called quantum theory, we are showing how particles, or quanta, run the whole show. The electromagnetic force was the first one to get a facelift, so let's check out how these quantum field theories work by looking at quantum electrodynamics!

Relativity comes in different flavors, as it happens. We spent some time looking at Einstein's special relativity, so now it's time for the general variety. This is all about the geometry of spacetime, which curves around massive objects. This was a huge update on our understanding of gravity, so get on board!

Ancient Rome Part 3: The Later Empire (250 – 500 CE)

Sun, 09 Aug 2026 11:56:00 -0000

After the crisis of the third century, the later Roman Empire took shape. This period involved many different leaders, great political change, and the eventual splintering of the empire into Western and Eastern halves, the former of which would eventually dissolve, and the latter of which would become the Byzantine empire. Let's go through the details!

Everyone and their mom knows about E = mc^2, it's the most famous equation in science, and there are plenty of posters you can buy for your dorm room with Einstein's face and this equation floating mysteriously around his head. But what does it mean? You'd better know if you're gonna get that poster! What if that cute boy or girl from class comes over and asks you about it and you don't know what you're talking about? That will be super embarrassing. You'd better watch this.

Types of Fingerprint Patterns

Sat, 08 Aug 2026 11:56:00 -0000

We just learned how fingerprint patterns form, so now let's learn how to categorize them. There are three main types of fingerprint patterns, those being whorls, loops, and arches. In order to identify these, we have to learn about cores and deltas. Then we can learn about all the subcategories within each type. It's more interesting than you think!

Special Relativity Part 2: Time Dilation and the Twin Paradox

Sat, 08 Aug 2026 05:56:00 -0000

We got our feet wet with special relativity, so now let's head to the deep end! Remember in Interstellar when what's his face went down to that one planet and Good Will Hunting was there and they fought and when what's his face went back a bunch of time had passed? That's time dilation! Pretty neat plot device if you ask me. Time passes at different rates for different observers. It's as true as anything can be. Check it out! Bring your twin for some fun with paradoxes.

The Diffusion Equation Part 2: Dimensional Analysis and Self-Similarity

Fri, 07 Aug 2026 23:56:00 -0000

In the previous tutorial we introduced the wave equation, and learned one way to solve it. Now let's look at another method for getting a solution. This will require that we brush up on dimensional analysis, so let's get to it!

Special Relativity Part 1: From Galileo to Einstein

Fri, 07 Aug 2026 17:56:00 -0000

We talked a little bit about relative motion in the classical physics course, with Galileo dropping stuff in boats. But once Einstein got his hands on relativity, he went a little nutty with it! The inertial reference frames are back but now we are talking about objects moving near the speed of light, which is where things start to get a little... weird.

Steve Kirsch: King Douche of the Anti-Vaxxers

Remember my live debate with Steve Kirsch and Pierre Kory, the idiot anti-vaxxer frauds? Humiliating them live was awesome, but they also deserve to have their entire histories of fraudulence exposed. This means that each of them need their own video, and this one is Steve's. Let's laugh at his delusion and incompetence together, shall we?

The Heisenberg Uncertainty Principle Part 2: Energy/Time and Quantum Fluctuation

Fri, 07 Aug 2026 05:56:00 -0000

Get ready for one of the weirdest things in modern physics. Particles that pop into existence from nothing and then go back to nothing again! This phenomenon, called quantum fluctuation, is happening all the time, all around you and even inside of you. It's the quantum foam, and it elucidates the third law of thermodynamics.

Quantum Mechanics and the Schrödinger Equation

Thu, 06 Aug 2026 05:56:00 -0000

Okay, it's time to dig into quantum mechanics! Don't worry, we won't get into the math just yet, for now we just want to understand what the math represents, and come away with a new and improved view of the electron as both a circular standing wave and a cloud of probability density. Spooky! Let's introduce the Schrödinger equation!

Reacting to Quantum Mystic "Higher Frequency" Self-Help Rubbish

Wed, 05 Aug 2026 23:56:00 -0000

Some jerk named Robert Edward Grant spewed a bunch of quantum mysticism crap about "moving into higher frequencies", which is literally meaningless, and some idiotic channel named Video Advice made a garbage animation to go along with it. What resulted was 15-minutes of nausea-inducing, transparently pseudoscientific self-help snake oil. So let's make fun of it for an hour.

Wed, 05 Aug 2026 17:56:00 -0000

The double-slit experiment is a classic experiment that is frequently referred to when describing quantum phenomena, so we definitely have to go over it a little bit. What happens when you pass a beam of light through a screen with two slits? What about when you send electrons through there? Or just one electron? It's crazy stuff! Check it out.

Quantization of Energy Part 2: Photons, Electrons, and Wave-Particle Duality

Wed, 05 Aug 2026 05:56:00 -0000

So Max Planck kicked things off, but how does the story of modern physics continue? With none other than your favorite scientist and mine, Albert Einstein! He did more than just stick his tongue out and have crazy hair. He elucidated the nature of the photoelectric effect back while working as a patent clerk in Switzerland. Must have been a boring job, because Einstein changed the world with his wandering mind!

Individual Characteristics of Fingerprints

Tue, 04 Aug 2026 11:56:00 -0000

Now we have the basic types of fingerprint patterns down. But is that enough? Far from it. Now we have to examine the individual characteristics of fingerprints that make them undeniably unique to a specific person. These are called Galton details, or minutiae, and they include things like ridge endings, bifurcations, and much more. Let's get a better sense of them now!

Pierre Kory: The Ivermectin Fraud Whose Lies Killed Thousands

Mon, 03 Aug 2026 23:56:00 -0000

After my live vaccine debate with Steve Kirsch and Pierre Kory, I promised to even further expose them both with their own videos. With Steve already covered, let's further expose Pierre Kory. This is the jerk that is responsible for the ivermectin craze during the pandemic. He claimed it was a miracle drug that would both cure and prevent COVID. Amazing! Except it did neither of those things. At all. But thousands of people believed him, some overdosed and died from ivermectin, and thousands of people delayed legitimate care waiting for ivermectin in the mail only for their condition to worsen such that when they got to the hospital, it was too late for doctors to help them and they died. Pierre Kory is responsible for thousands of deaths, so let's rake him over the coals until everyone knows what a worthless fraud he is.

Electric Charge and Electric Fields

Sun, 02 Aug 2026 17:56:00 -0000

What's the deal with electricity? Benjamin Franklin flies a kite one day and then all of a sudden you can charge your phone? There's a gap in conceptual understanding! Let's figure out what electricity is, exactly, and how it works, by defining electric charge and electric fields.

Avi Loeb is a Fraud Part 2: 3I/ATLAS Shrugged

Sun, 02 Aug 2026 11:56:00 -0000

A few months ago I exposed Harvard astrophysicist Avi Loeb as a grifting fraud, whose entire "scientific output" over the past decade or so, has been limited to unpublished preprints lying about astronomical phenomena that he then blasts to the media to garner fame and sell shitty books full of lies. He's completed two rounds of this behavior, first with exocomet 'Oumuamua, which he pretended was a spaceship, and then with a meteor that landed in the Pacific Ocean, which he also pretended was a spaceship, while he pretended to have retrieved fragments of it. Through this behavior he had already been known to be a massive fraud among the scientific community. But round three of the Avi Loeb grifter playbook has been in full effect since July of this year, with the discovery of exocomet 3I/ATLAS. He's been running his mouth about how this is aliens as well, lying through his teeth about every single aspect of this object, every single day, on any platform that will host him. He's gearing up for another shitty book and other blatant cash grabs, while also cuing up some other shady developments for himself, so let's take him down a notch by showing the world what a pathetic grifting fraud he's been regarding this object, shall we?

What is Light? Maxwell and the Electromagnetic Spectrum

Sat, 01 Aug 2026 17:56:00 -0000

Up until a couple centuries ago, we had no idea what light is. It seems like magic, no? But there is no magic in this world, really. Just stuff we don't understand. So let's understand light a little better right now, through James Clerk Maxwell and the electromagnetic spectrum.

Reacting to Braindead Apologist on the Origin of Life

Sat, 01 Aug 2026 11:56:00 -0000

Today we are reacting to some jerk named Don Batten who really hates the idea that life on Earth came about by natural processes, because it contradicts his baseless religious ideology regarding a magic sky daddy making humans super special just the way they are 6,000 years ago. He has a cute little script to try and discredit this possibility, and if you thought James Tour was stupid, you'd better buckle up.

Standing Waves and Harmonics

Sat, 01 Aug 2026 05:56:00 -0000

Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better learn about this concept before digging into modern physics.

Ancient China Part 2: The Zhou Dynasty (1000 – 200 BCE)

Fri, 31 Jul 2026 23:56:00 -0000

After learning about the Shang Dynasty, it's time to move on to the Zhou Dynasty. This will include the Western Zhou of the 11th through 8th centuries BCE, as well as the Eastern Zhou, which includes the Spring and Autumn period and Warring States period of the 8th through 3rd centuries BCE. What sorts of changes did this era entail? Let's take a look!

The Third Law of Thermodynamics: Absolute Zero

Thu, 30 Jul 2026 17:56:00 -0000

Brr, it's so cold today! Could it get any colder? Is there a coldest possible temperature? Yes, there is! That seems strange, but now we know that temperature is just a measure of kinetic energy, so zero kinetic energy must mean zero temperature! Let's learn more about this winter wonderland of physics as we wrap up our adventures with the laws of thermodynamics.

The Zeroth Law of Thermodynamics: Thermal Equilibrium

Wed, 29 Jul 2026 05:56:00 -0000

You've heard of the laws of thermodynamics, but did you know there are actually four of them? It's true, and since they already had laws one, two, and three, but then wanted to formulate another more fundamental one, the number right before one is zero so that's what they called it! Also, "zeroth" is fun to say. Let's say it together.

We know a lot about fingerprints by now, but how do we record them? It can be done manually or digitally, and there's actually quite a bit to the technique! Let's run through the protocol now.

Fluids, Buoyancy, and Archimedes' Principle

Mon, 27 Jul 2026 17:56:00 -0000

Archimedes is not just the owl from the Sword in the Stone. Although that's a sweet movie if you haven't seen it. He was also an old Greek dude who figured out a bunch of physics way before other people did. Some of this was discovered at bath time, so it has a lot to do with water, but don't get all weird about it, just listen to the old man in the tub. He's smarter than he looks.

COVID Origins: Debunking the Grift, Pseudoscience, and Politics of the Lab Leak Theory

Mon, 27 Jul 2026 11:56:00 -0000

Remember the COVID-19 pandemic? That was crazy, right? And did you hear that the virus responsible, SARS-CoV-2, leaked from a virology lab in Wuhan? And that it may even have been deliberately leaked to act as a bioweapon? You definitely heard that. Everybody has. But is it true? Well... I mean what's the alternative? All those stupid scientists talking about how it almost certainly originated from a wet market, with live animals coughing and crapping everywhere, just like so many other documented spillover events, what sense does that make? Those people are stupid establishment shills, right? Well, why don't we talk about it in excruciating detail for a couple hours? That should clear everything up.

Angular Motion and Torque

Mon, 27 Jul 2026 05:56:00 -0000

More spinning things! Records, and wheels, and doors, and other fun things. The equations that govern this kind of motion are just like the ones we learned in kinematics, except they have different symbols. Lots of funky Greek letters in this one, folks.

Newton's Law of Universal Gravitation

Sun, 26 Jul 2026 17:56:00 -0000

You thought we were all done with Newton, didn't you? You figured that three laws are enough for any scientist. Well think again! Newton was quite the champ, and his work with gravity was revolutionary. I mean, the guy invented calculus so that he could do his work on gravity. So when he INVENTED CALCULUS, he did it just so that math could exist that was complicated enough to do stuff that was more important than inventing calculus. Think about that for a while. Then watch this. Then think about it again.

Uniform Circular Motion and Centripetal Force

Sun, 26 Jul 2026 05:56:00 -0000

Enough of this moving in straight lines business, let's go in circles! Circular motion may not be productive but it's super fun. Ferris wheels are fun. Yes they are, don't be a spoilsport. Roller coasters are fun too. And merry-go-rounds. And learning about centripetal force. Look, I don't understand why you're resisting so much, we are talking about a freaking amusement park. Fine, be that way, I'll go by myself. You stay here and learn this math!

Remember when Dr. Mike took on the 20 anti-vaxxers in the Jubilee thing? I reacted to it and everybody thought that was a grand old time. Then he went on there again to debate RFK Jr. supporters. A little redundant, since there is 100% overlap between those groups, but who cares? Another several hours of stupidity and insanity to react to! A lot of you asked for this one, so please enjoy as my holiday gift to you!

Elastic and Inelastic Collisions

Sat, 25 Jul 2026 17:56:00 -0000

When you take a shot on a pool table or tackle someone in a football game, you're participating in a collision. But the two events we just mentioned are totally different kinds of collisions! But what are elastic collisions, and what are inelastic collisions? We have to learn the varieties and what they mean for momentum and energy.

Impulse and Momentum

Sat, 25 Jul 2026 05:56:00 -0000

As much as we frequently misuse scientific words in common language, we do have a reasonable grasp of the word momentum. But that's no reason to gloss over this concept, we have to know all the definitions and equations there are! The same goes for the concept of impulse. Check this one out, there are trampolines and baseball.

Jimmy Corsetti is Human Garbage

Fri, 24 Jul 2026 23:56:00 -0000

After exposing Graham Hancock, the godfather of the pseudoarcheology cult, I vowed to go after all of his loser acolytes one by one, starting with Dan Richards and Jimmy Corsetti. We covered Dan already, so now it's Jimmy's turn. This guy is a real gigantic turd, pushing lies and conspiracy theories about Göbekli Tepe, Atlantis, the pyramids at Giza, you name it. The blatant lies about archeological sites would be bad enough on their own, but he is also truly the worst troll in this cult by a mile, just a racist, misogynistic monster harassing scholars on a daily basis, mobilizing his brainwashed followers to try and get them fired from their jobs, and all manner of other vile, toxic behavior. So let's make fun of this pointless fraud for a solid two hours, yeah?

Discussing Pseudoscience With Archeologist Flint Dibble

Thu, 23 Jul 2026 23:56:00 -0000

You may remember archeologist Flint Dibble from my great big pseudoarcheology debunk exposing Graham Hancock as a fraud. A lot of his followers also fall for other frauds I've debunked, like Avi Loeb, Bobby Kennedy, and more. Let's talk with Flint about the art of debunking, the status of public science literacy, and what can be done to put society on the right track.

Class Sarcopterygii: Lobe-Finned Fishes and Tetrapods

Thu, 23 Jul 2026 11:56:00 -0000

That took a while, but we finally finished our investigation of Actinopterygii, the ray-finned fish. Now let's look at the other major clade within Osteichthyes, the lobe-finned fish of Sarcopterygii. This is the clade that gave rise to the tetrapods, like amphibians, reptiles, and mammals. Let's start by looking at coelacanths and lungfish.

Introduction to Particle Physics: A Tour of the Standard Model

Wed, 22 Jul 2026 23:56:00 -0000

After a deep dive into quantum mechanics, it's time to do the same for particle physics. What is the Standard Model of particle physics? What are all the particles in there, and how did we discover them? How can we use this model to do calculations? What is the future of the field? Let's learn all about it!

Frictional Forces: Static and Kinetic

Wed, 22 Jul 2026 17:56:00 -0000

Newton's first law tells us that an object in motion will remain in motion, but we don't really see that on earth, do we? If you throw a ball, or push a hockey puck, these things do eventually stop. Why? To answer this we must learn about static and kinetic friction!

My 2026 Bingo Card (Featuring Mr. Beat and J. J. McCullough)

Wed, 22 Jul 2026 11:56:00 -0000

2025 has come to a close! And what a shitshow it was. What does 2026 have in store for us? Mr. Beat, JJ McCullough and I have made some bingo cards with predictions. Some of us took it more seriously than others. Spoiler alert: I did not take it seriously. That's my bad. But between the three of us we have some great predictions that stirred some interesting conversation. Let's reflect on the year and share our hopes and fears for next year together!

Mass vs. Weight and the Normal Force

Wed, 22 Jul 2026 05:56:00 -0000

Mass is just a fancy sciency word for weight, right? Wrong! Although related, they aren't the same thing. You'd better find out exactly what the difference is so that you don't look foolish around the water cooler! Oh and the normal force, let's find out what that is too.

Newton's Third Law of Motion: Action and Reaction

Tue, 21 Jul 2026 17:56:00 -0000

Are you tired of Newton's laws of motion yet? Well, lucky you, this is the last one. And it's the most misunderstood as well! People love making inappropriate metaphors with scientific principles, unfortunately. Watch this to make sure you don't do the same!

Newton's Second Law of Motion: F = ma

Tue, 21 Jul 2026 05:56:00 -0000

One of the best things about Newton was the way that he showed how natural phenomena abide by rigid mathematical principles. So much so that we can use mathematical equations to calculate how objects will actually behave. This equation, F = ma, looks pretty tame, but it packs a punch!

Newton's First Law of Motion: Mass and Inertia

Mon, 20 Jul 2026 17:56:00 -0000

Did you know that if you throw a rock in space, whatever velocity it has at the moment that it leaves your hand, it will continue moving with that velocity indefinitely? That's Newton's first law. It applies to objects on earth as well, it's just that earth's atmosphere complicates matters. Get the full breakdown here!

Particle Decay Rates and Cross Sections

Mon, 20 Jul 2026 11:56:00 -0000

To substantiate the Standard Model of Particle Physics, we look for certain kinds of particle interactions and other events, including particle decay. Why do decay events produce the kinds of particles they produce, and why do particles decay at all? It's a complicated question, but let's talk about it!

Mon, 20 Jul 2026 05:56:00 -0000

What's a force? No, not THE force. That's from Star Wars. I'm talking about the forces in the universe that make things move. Yes, I know Yoda moved the X-Wing with The Force. Will you quit it? We are talking about the real universe here. Fine, I guess it could be the same universe as ours, but why are there humans that speak English in a galaxy far, far away? Alright fine, go watch a Star War first and then come back to me when you want to learn some real physics.

Class Amphibia Part 1: General Characteristics and Development

Sun, 19 Jul 2026 23:56:00 -0000

Continuing through phylum Chordata, we arrive at class Amphibia, the first of the tetrapods. How did they evolve, and what do they look like today? Most people know about frogs and salamanders, but what about caecilians and other strange creatures? Let's take a look!

Relative Motion and Inertial Reference Frames

Did you know that everything is moving? Even you, as you're sitting perfectly still, because the earth is moving, and the sun, and the galaxy, and so forth. For this reason, it only makes sense to talk about the motion of some object relative to some other object, just as Galileo told us. Watch this and see what I mean!

Personal Pronouns in Latin

Sun, 19 Jul 2026 11:56:00 -0000

Edward Henry, along with Azizul Haque and Hemchandra Bose, came up with a rigorous system of fingerprint classification in 1897. How does this system work, and what are its benefits? What is meant by primary, secondary, sub-secondary, and final classification? What about key and major? Let's go through all the details.

Steve Kirsch Strikes Back! (And Soils Himself)

Thu, 16 Jul 2026 11:56:00 -0000

Remember Steve Kirsch, king douche of the anti-vaxxers? Dan Wilson and I humiliated him in a live debate in New York, and then I made follow-up videos on him and Pierre Kory to further expose their extreme fraudulence. When you're a lying piece of excrement who spreads anti-science propaganda that gets people killed, you really don't deserve any mercy. After several months of licking his wounds and crying, Steve finally decided to strike back. Brace yourself, it's pathetic. Let's knock him back down to the ground where he belongs, shall we?

Scalars, Vectors, and Vector Operations

Thu, 16 Jul 2026 05:56:00 -0000

What are all these funny little arrows? They're vectors! And we will use them to represent every single force we discuss in physics, so we need to know how to draw them, add them, subtract them, split them up into X and Y components, the whole nine yards. We also need to know the difference between vectors and scalars. So let's get this stuff taken care of before we dive into the physics!

Introduction to the Middle Ages (500 - 1500 CE)

Wed, 15 Jul 2026 23:56:00 -0000

With antiquity covered, it's time to start learning about the Middle Ages. This is the period starting roughly around 500 CE that lasted all the way until the Renaissance. What was happening at that time in Europe, Asia, Africa, and Mesoamerica? Let's outline this portion of the series so that you know what to expect!

Introduction to Classical Physics

Wed, 15 Jul 2026 17:56:00 -0000

Physics is the grandaddy of the sciences! When those ancient dudes in togas were philosophizing about the way the universe works, they were setting the stage for what we now know of as physics, even though it didn't really get going until Galileo and Newton. Why should we study physics? What is the goal of physics? What do we mean when we refer to classical physics? Let's reflect together for a moment before we dive into this hefty subject, shall we?

Why You Should Never Say "It's Just A Theory"

Wed, 15 Jul 2026 05:56:00 -0000

A portion of our culture distrusts the scientific method, assuming that there are transcendent truths unknowable by science. But nothing is truly out of bounds for science. If it's real, it can be studied, and tested. Perhaps the greatest misunderstanding our culture has about the scientific method involves the definition of the word "theory". A theory is not a guess, and this word does not in any way imply uncertainty about the validity of a concept or an equation. Watch this and learn more about the terms hypothesis, theory, and law.

Pharmaceutical Drugs: Inhibitors and the Nature of Disease

Tue, 14 Jul 2026 17:56:00 -0000

We live in a time where there is much skepticism towards modern medicine. This stems purely from ignorance, however, and there are those who capitalize on this to sell an unbelievable array of alternative medicines that, almost without exception, do absolutely nothing. Let's take a look at the kinds of diseases that exist, what they are on the molecular level, and the scientific strategies available to combat them. We don't need to defend the pharmaceutical industry, but we definitely need to understand that the science behind pharmaceutical drugs is the only strategy available that truly addresses the cause of any medical condition in an informed way, and is therefore the only intelligent approach to treatment.

Illicit Drugs: How Do They Work?

Tue, 14 Jul 2026 05:56:00 -0000

Drugs of all varieties are very interesting from a biochemical standpoint, as they produce an incredible array of physiological effects. These effects are due to the shape of each molecule, which determines the cellular components they interact with. Let's learn a bit about some of the common illicit drugs from an academic standpoint.

Of all the frauds out there spreading disinformation about vaccines and related topics, few are as morally bankrupt as Peter McCullough and his crew. Once a real cardiologist, he pivoted to grifting at the start of the pandemic, and now spends all of his time cobbling together fake research fabricating apocalyptic dangers for vaccines that will terrify the public and drive them over to his supplement-peddling business, the Wellness Company. We will also go over his douchebag henchmen Nic Hulscher, Kevin McKernan, John Catanzaro, as well as familiar faces like Bobby Kennedy and Andrew Wakefield. Here comes the clown show.

Cell Communication: Hormones and Neurotransmitters

Mon, 13 Jul 2026 05:56:00 -0000

We already learned a little bit about receptors and the signaling pathways that they initiate, but what are the molecules the travel throughout your body, carrying messages like little carrier pigeons? They are called hormones and neurotransmitters, and you can't even begin the imagine the variety of cellular processes they regulate. Let's take a look!

Now that we have a basic understanding of the components of the Standard Model, let's start digging into the math. What did the first attempts to construct a relativistic version of the wave equation yield? We have the Klein-Gordon equation, and then the Dirac Equation. What are these equations and what do they tell us? Let's find out!

Sun, 12 Jul 2026 05:56:00 -0000

The trilogy is finally concluded! And with a bang, no less, as this final stage of cellular respiration is the one that provides the big energy payoff for the cell. Let's learn about how the products of the Citric Acid cycle go on to the electron transport chain to facilitate reactions that will generate a proton gradient suitable for powering ATP synthase, one of the most fascinating proteins in the body.

Remember when I made a little reaction video making fun of some random creationists, including a cringy after school special? One of the other videos was made by some jerk named Jay Dyer. He didn't appreciate me mocking his profound stupidity, so he threw a little tantrum in response. Big mistake. Wanna see just how stupid and pointless this wiener is? Oh, and racist and sexist to boot! Let's mock him some more together.

Remember how I've promised to ruin the pseudoarcheology cult? I started with Graham Hancock, then I moved on to Dan Richards and Jimmy Corsetti, and it's time for a few other targets. But first we have to hit Dan Richards one more time. He's big mad about being exposed as a pathetic loser and fraud in front of millions of people, so he decided to mouth off about me again, so it's a great opportunity to dunk on his dumb unkempt face while also teaching some important information about the history of science. Let's all point and laugh!

Dunking on Creationist Idiot Jimbob in Live Debate

Fri, 10 Jul 2026 23:56:00 -0000

A couple days ago I made a video mocking possibly the dumbest and most pathetic creationist I've ever encountered. His name is Jay Dyer and he's a science illiterate philbro who didn't like it when I reacted to a video he did fumbling 9th grade level biology. So he made a video response where he basically just mocked me in a racist Jewish voice the whole time. Not exaggerating. His idiot friend Jimbob was in the video I initially reacted to, and he didn't like me making fun of them, so he demanded to be let onto a livestream I was participating in so that he could debate me. Not really a wise decision. I mopped the floor with him for 30 minutes. Want to see? Of course you do.

Mechanisms of DNA Damage and Repair

Fri, 10 Jul 2026 05:56:00 -0000

Remember how the Ninja Turtles came to be? Yes you do. It was the ooze! A radioactive ooze that mutated their DNA in just the right way to give them the ability to walk upright, talk, and do ninjutsu. Now, I'm as a big a Turtle fan as they come (Donatello is my main man) but this is a highly inaccurate way to portray mutation. Let's learn about the real ways that your DNA can become damaged, and the strategies nature has developed to combat these risks.

The Early Middle Ages: Charlemagne and His Successors

Thu, 09 Jul 2026 23:56:00 -0000

Let's kick off our study of the Middle Ages by looking at Western Europe. The Roman Empire had splintered into two halves. In the east there was the Byzantine Empire, but the west had split up into separate kingdoms rules by various Germanic tribes. Over time this morphed into the Holy Roman Empire, based in modern day Germany. Charlemagne was the first ruler of this empire, so let's learn about him and other associated figures.

Jay Dyer and Jimbob are Spiraling

Thu, 09 Jul 2026 11:56:00 -0000

Jay Dyer and Jimbob are having a really tough time with the whole internet making fun of them for being the dumbest people alive. And they are eager to make everything much worse for themselves! After mocking Jay's pathetic response to my reaction video humiliating them, and then Jimbob begging to debate me which resulted in even further humiliation, they've been desperately logging six-hour livestreams spewing the most transparent damage control imaginable. Let's see what pathetic antics they've been performing, shall we?

Wed, 08 Jul 2026 17:56:00 -0000

We've been hearing about DNA since the third grade, and we all know that it's a double helix with little ladder rungs. But now we are ready to understand this molecule on a more fundamental level, which will enable to us to understand how this molecule can serve as the genetic code. Let's see what nucleic acids are all about!

Kent Hovind is Still Grifting!

Would you believe me if I told you that Kent Hovind is still alive, and still running the same pathetic grifter script? It's true. Jail time can't keep this guy down. Tax evasion, wife beating, pedophile-enabling be damned! He's gotta get the word out about Jesus and that evil demonic religion of evolution. Join me in mocking this turd sandwich as he's interviewed by some guy named George Janko. There's some funny stuff in here.

Symmetries in Particle Physics

Tue, 07 Jul 2026 11:56:00 -0000

One of the most important concepts in particle physics is symmetry. And this goes way deeper than just thinking about simple reflections. There are abstract symmetries that are directly responsible for fundamental conservation laws. There are also thinks called gauge symmetries. Let's get a closer look!

Lipids Part 2: Steroids

Tue, 07 Jul 2026 05:56:00 -0000

Steroids have gotten a pretty bad rap! In reality, they're not just the big bad anabolic steroids. This class of molecules includes many vitamins as well as cholesterol. Cholesterol has also gotten a bad rap! We need cholesterol for our cell membranes to be rigid enough to stay intact, and for our bodies to build other important molecules. What I'm saying is that you should watch all of these tutorials, and don't believe everything you hear around town about molecules!

Latin Vocabulary: Dies, Menses, Tempora (Days, Months, and Seasons) and Using Roman Numerals

Sun, 05 Jul 2026 23:56:00 -0000

It's time for more Latin vocabulary! If you want to read the classical authors, you will have to understand vocabulary relating to time. This includes the seasons, months of the year, and days of the week. It's also good to know where these names came from, as they are all cultural references. We should also know how to read a Roman calendar, so that we can finally know what Ides of March really means! And then lastly, it will be important to be able to read Roman numerals, so let's cover that too.

Enzymes: Nature's Factory Workers

Sat, 04 Jul 2026 17:56:00 -0000

What are enzymes? Why they're nature's little factory workers. They chop up certain things! They build up others! Pretty amazing the kind of chemistry nature can do given enormous polypeptide chains with unfathomable variability and billions of years of evolution, no?

Moon Landing Deniers are Idiots: Bart Sibrel Debunked (Part 2 of 2)

Sat, 04 Jul 2026 11:56:00 -0000

As we demonstrated in part 1, moon landing deniers are almost as dumb as flat earthers. And the king of this cult is a grifting fraud named Bart Sibrel. He really, really, really wants you to go to his website where he has compiled a bunch of deceptive clips and outright lies to trick people into denying that humans have been to the moon. With the Joe Rogan episode covered, we move on to two appearances on the Danny Jones podcast, one of which involved Apollo 16 astronaut, Charlie Duke. Want to see what a worthless cretin Bart is towards an old man that definitely walked on the moon? Strap in.

Protein Structure

Sat, 04 Jul 2026 05:56:00 -0000

Everyone has heard of proteins. What are they on the molecular level? They're polymers of amino acids, of course. They make up most of your body, so we have to understand their structure very well! Check this out to learn the hierarchy of protein structure so that we can later learn all about what different types of proteins can do.

The High Middle Ages Part 2: Crusades and Inquisitions

Wed, 01 Jul 2026 11:56:00 -0000

After examining the changes in government and economics during the High Middle Ages, let's turn to the religious and ideological conflicts of the period. Tensions were increasing between the Christian and Muslim worlds, and there were also conflicts with the various sects of Christianity. This led to the Crusades as well as the first of several inquisitions. This stuff can get pretty gruesome, but let's dive into it.

Practice Problems: Labeling Carbons

Wed, 01 Jul 2026 05:56:00 -0000

What's with this hierarchy? Primary, secondary, tertiary... can't all carbons be equal? Well, no. We need to be able to label the degree of substitution of any carbon in an organic molecule so that we can make predictions about the chemistry that can occur. But don't worry, they won't get their feelings hurt.

Discussion on the Science Counterpunch Podcast (The Urgency of Science Communication)

Mon, 29 Jun 2026 23:56:00 -0000

Dave appears on the brand new Science Counterpunch podcast with co-hosts Sam Gregson and Philipp Markolin. You may recognize Sam from his channel Bad Boy of Science, and from his contribution to one of my videos exposing Sabine Hossenfelder. And you may recognize Phil from my video debunking the COVID lab leak conspiracy, which was a collaboration that would be impossible without his research and command of the topic. These guys are the real deal, they know how urgent it is to address science denial in its myriad forms. So join us for a discussion on how to best do precisely that.

Professor Jiang is an Idiot (Predictive History Reaction)

Who is this guy Professor Jiang that everyone is talking about? He runs a channel called Predictive History, where he pretends to be delivering lectures to students, but he's actually just going on delusional rants where he fumbles the most trivial aspects of every scientific discipline, and spews insane conspiracy theories about geopolitics. The only thing crazier than his ridiculous sermons is the fact that he has been exploding in popularity over the past few weeks based on some not-even-remotely-impressive "predictions" that he made about global affairs. Let's take him down a notch, shall we?

Sat, 27 Jun 2026 11:56:00 -0000

After learning is-ea-id, we need to learn about the demonstrative, īdem-eadem-idem. This means "the same", and the grammar related to it is quite interesting.

The Telepathy Tapes Are a Scam (Ky Dickens Debunked)

Fri, 26 Jun 2026 23:56:00 -0000

Have you heard that nonverbal severely autistic children have telepathy and other psychic powers? They don't, it's bullshit. But there's a very popular podcast called The Telepathy Tapes that makes this claim. Ky Dickens, the creator, is a lying fraud who preys upon distressed parents of severely autistic children and the gullible sector of the public that wants magic to be real. This grift goes back farther than you think, so let's elucidate some very important context and then explain exactly how Ky's grift works.

Practice Problem: Analyzing Acid-Base Equilibria

Fri, 26 Jun 2026 05:56:00 -0000

Acids! Bases! Conjugate acids! Conjugate bases! We definitely have to be able to label such things, and we should also know how to state which direction in an acid-base equilibrium is preferred. To do this we should know how to tell which acid is stronger, and to do that we have to understand stabilizing factors for the conjugate base, which means we need to understand resonance and electronegativity, which means we need to understand quantum mechanics, which means... oh just watch this.

Metatron is a Whiny Little Baby

Wed, 24 Jun 2026 23:56:00 -0000

My recent video examining reality denial and the behavior of trolls that infest my channel featured a tantrum by a loser named Metatron, where I mocked him for being a toxic troll that whines about how toxic I am. He didn't like it very much, so he decided to throw yet another toddler tantrum and accuse me of lying while doubling down on the toxic stuff. He's delusional, and also hilarious, so let's drag him through the mud a little bit such that everyone can know how pathetic this guy is.

I've seen it a thousand times. You wanna do some transformation on a molecule, and it would work so wonderfully if this other functional group wasn't on the molecule to screw it up! You don't even want that other group to do any chemistry at all, isn't there some way to make it sit this round out? Protecting groups to the rescue!

Introduction to Quantum Chromodynamics (QCD)

Tue, 23 Jun 2026 11:56:00 -0000

With QED covered, it's time to move on the quantum chromodynamics, or QCD. This is the QFT that governs the strong nuclear force, so it explains the behavior and interaction of quarks through mediator bosons known as gluons. What are the symmetries involved for QCD? What are quarks exactly? What is color charge? How can we create Feynman diagrams for this model? Let's talk about it!

Introducing the Perfect System in Latin: Present Perfect

Mon, 22 Jun 2026 23:56:00 -0000

The Perfect System is comprised of three tenses that all describe completely finished actions, the present perfect, pluperfect, and future perfect. All of these tenses are formed from the third principle part of a verb. Let's get some general information about this system and learn how to construct the present perfect tense.

Disarming Climate Change Denial Tropes (Featuring Peter Hadfield aka Potholer54)

Mon, 22 Jun 2026 11:56:00 -0000

We've covered climate change denial in one video before, which was very thorough, but for a pressing issue like this, one topic is never enough. To help us disarm some common talking points put forth by climate change deniers is Peter Hadfield, better known as Potholer54. He's a geologist and science journalist who has covered this topic extensively, so let's get some pearls of wisdom from him on how to combat this fallacious rhetoric!

Did you guys know that flat earthers still exist? It's crazy, right? Despite the "community" being in shambles after the Antarctica trip, all your favorite douchebags like Eric Dubay, David Weiss, and Mark Sargent are still grifting their faces off. The recent Artemis II mission has really set them off, as you can expect. So much footage, so many images, a huge mountain of undeniable proof that the Earth isn't flat. How do you think they'll handle it? In the most intellectually bankrupt manner humanly possible? Bingo. Grab some popcorn and enjoy the show.

Introduction to the Weak Interaction

Thu, 18 Jun 2026 23:56:00 -0000

After discussing how QED governs the electromagnetic force, and QCD governs the strong nuclear force, we are ready to move on to the weak nuclear force, or the weak interaction. This is mediated by W and Z bosons, and is responsible for processes like beta decay and nuclear fusion. Let's see how this phenomenon is explained by the Standard Model.

Baiting Flat Earth Dave With AI Images (Artemis Bonus Episode!)

Thu, 18 Jun 2026 11:56:00 -0000

Since everyone seemed to enjoy my recent video on flat earthers freaking out about the Artemis II mission, how about a little bonus episode? Right after posting that video, someone informed me that they had been baiting David Weiss, posing as a pilot who flew the vomit comet that allowed them to fake the Orion interior shots. And the dumbass bought it! He used AI-generated pictures and testimony in his recent content. Let's go over all the details and mock him some more, shall we?

NASA's Artemis Program: Future Goals (Featuring Scott Solomon)

Wed, 17 Jun 2026 11:56:00 -0000

With the Artemis II mission completed, what's next for the Artemis program? What will be the goals of the next set of missions? Will we build a permanent lunar base? What about a Martian base? Who will live on these bases and what will they do? What are the biological concerns related to living off-Earth for extended periods of time? Let's go over some details, and then speak with biologist Scott Solomon, whose new book deals with precisely these questions.

Late Middle Ages Part 2: The Foundations of the Renaissance

Tue, 16 Jun 2026 23:56:00 -0000

Apart from war and famine, the Late Middle Ages also saw significant political change. Secular rulers and the Papacy were constantly at odds in terms of who had power over whom. All of this turmoil culminated in the beginning of the Renaissance, so let's see how we got there.

Sat, 13 Jun 2026 23:56:00 -0000

Reflexive pronouns refer back to the subject of the clause they are found in, meaning they refer to the doer of the action. In English we use them when we say things like "I blame myself". How does this work in Latin? Let's find out!

Ky Dickens Tried to Censor My Telepathy Tapes Debunk

Sat, 13 Jun 2026 11:56:00 -0000

Last month I debunked a garbage podcast called The Telepathy Tapes, along with Ky Dickens, the grifter behind it. She wasn't too happy about it, so she tried to get my video banned from YouTube. She was unsuccessful, and only brought more attention upon herself, since it turns out that this behavior is a pattern for her. Let's talk to Janyce Boynton, a previous recipient of Ky's attempts at censorship, and get some more clarity on who Ky is and what she's doing.

Acid-Base Equilibria and Buffer Solutions

Sat, 13 Jun 2026 05:56:00 -0000

Remember those pesky iceboxes? Weak acids and bases establish equilibria, so we have to do iceboxes to figure out things about them. But don't worry, buffers are neat.

Acids and Bases, pH and pOH

Fri, 12 Jun 2026 17:56:00 -0000

We've all heard the terms acid and base. What do these mean? Don't just tell me about pH, silly. What structural detail makes a molecule an acid or a base? You don't know? Well, you'd better watch this then. You don't want to be embarrassed at the water cooler.

Aaron Siri is a Worthless Anti-Vaxx Stooge

Fri, 12 Jun 2026 11:56:00 -0000

Intelligent people are aware of what a complete nightmare RFK Jr. is. But he has a particular underling that is also quite vile, and who deserves to be exposed as well. That would be his attorney, Aaron Siri. Aaron is a lawyer whose firm handles cases for Bobby, as well as Del Bigtree's propaganda organization ICAN. He gets paid millions of dollars to concoct shady lawyerspeak that will score procedural wins in court which he can misrepresent and offer as proof that vaccines are harmful. He's been spewing his script of lies in front of the Senate and on Joe Rogan, and lots of people are falling for it, so let's tear it to shreds, shall we?

Valence Bond Theory, Hybrid Orbitals, and Molecular Orbital Theory

Fri, 12 Jun 2026 05:56:00 -0000

Attention! This video about molecular orbitals is much better: https://www.youtube.com/watch?v=I2k61JMk71M

Alright, let's be real. Nobody understands molecular orbitals when they first take chemistry. You just pretend you do, and then in your next course you learn them a little better. And then a little better than that. And five years later you sort of understand them. So don't get discouraged! Just watch this for a head start and do your best.

Le Chatelier's Principle

Thu, 11 Jun 2026 17:56:00 -0000

If a system is at equilibrium, and we do something to it, it will shift in a particular way. It is quite easy to predict the behavior of equilibria if we know about Le Chatelier's principle and three simple situations!

Possessive Adjectives and Pronouns in Latin

Thu, 11 Jun 2026 11:56:00 -0000

Possessive adjectives and pronouns describe ownership, and in Latin they must agree in case, gender, and number with the object that is possessed, not with the possessor. This might take some getting used to, but let's get a closer look!

Using Microbes to Turn Trash Into Energy? (Discussion With Sasha Rollings-Scattergood of Anaergia)

Tue, 09 Jun 2026 23:56:00 -0000

As a civilization, we produce way too much trash, and we use way too much energy that is derived from fossil fuels and other unsustainable sources. What if we could kill two birds with one stone? What if we could turn trash into energy? Well we can! With the help of some plucky little microbes, of course. Anaergia is a company that is turning trash into renewable natural gas and fertilizer on an industrial scale. This is proven carbon-negative technology that is already widespread in Europe, and it is starting to be developed in North America as well. This is great news for the environment, so let's learn all about it!

I Invaded the Podcast Bro Space (They Hated It)

Mon, 08 Jun 2026 11:56:00 -0000

The podcast bro space is destroying human civilization. People like Joe Rogan and his copycats consistently platform a string of grifting frauds whose lies poison public perception of science. This has culminated in the public welcoming the Trump administration, which between the supreme orange leader and evil henchman RFK Jr., are completely obliterating the American scientific community. Budgets have been slashed, federal institutions have been purged of anyone who will not bow down to the new state-sanctioned disinformation narrative, vaccine-preventable diseases are killing children once more, and everything is a mess. How can we get through to the brainwashed masses that exclusively gather their worldview from the frauds on these shows? What if we can invade their space! Well I managed to do that. I went on the Danny Jones podcast. How did it go? Let me tell you all about it!

Sun, 07 Jun 2026 11:56:00 -0000

Mothers go through all kinds of changes during pregnancy and after the birth of their child, in terms of hormones and broader psychological changes. But what about fathers? Do their brains change? When and how? Can we compare biological factors with sociological and anthropological ones? Darby Saxbe is a USC psychologist who wrote a book on this very topic. Let's chat with her and learn all about it!

Reacting to Stephen Meyer Being a Complete Moron

Sat, 06 Jun 2026 23:56:00 -0000

Stephen Meyer of the Christian propaganda mill "Discovery Institute" really has a fire under his ass right now! He's making appearances, releasing shitty pseudo-documentaries in theaters, his taskmasters really have put him to good use! Since Christian nationalists have been making serious progress in taking over the country and demolishing the separation of church and state, it's time to start dunking on this douchebag again. Let's start with a couple of short videos where he's being interviewed on some idiot apologist's podcast, and spewing his usual ridiculous script about DNA and "specified information", abiogenesis, all the greatest hits.

Were you under the impression that Terrence Howard was done being a complete lunatic? He is not. He made a "movie", and it's so bad. Seriously, you can't believe how bad it is. Take all of his insane ramblings, put them on top of AI slop and cheesy string music, and add in horrible production value. That's Terry's movie! Want to watch it with me and make fun of him?

Superintelligent AI: Cutting Through the Noise (Featuring Andrea Miotti)

Thu, 04 Jun 2026 23:56:00 -0000

We seem to be talking about AI a lot these days, as a society. Some issues are urgent right now, like the energy drain from huge data centers, impending unemployment surge, social media manipulation, and more. But that's not all! Did you know that superintelligent AI, which is currently under development, might murder all of us? Some people take this threat very seriously. Others do not. I personally think that we should take it quite seriously, and so does Andrea Miotti, CEO of ControlAI, a non-profit organization working towards achieving a global ban on superintelligent AI. Let's chat with Andrea about why the threat is credible and what we can do about it.

VSEPR Theory and Molecular Geometry

Thu, 04 Jun 2026 17:56:00 -0000

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary conditions, atoms came together to form molecules, and in doing so, they created the first shapes the universe had ever seen. Learn about the different shapes that molecules can make!

Exposing Discovery Institute Part 12: William Dembski

Thu, 04 Jun 2026 11:56:00 -0000

Next up in this series is Bill Dembski, the idiot fraud behind the pseudoscientific concept of "specified information". In a nutshell, it says that DNA is so crazy like a super crazy code and all codes come from minds so god must have made DNA. He uses a bunch of technical jargon from information theory incorrectly to make it sound more intellectual than that, but it isn't. Let's debunk the hell out of this bullshit and also mock him for all of his other culture war crap and desperate apologetics, shall we?

Guess who's still trying to pretend he isn't a pointless propaganda-peddling loser? Eric Weinstein! He recently went on Joe Rogan for the gazillionth time, where he spewed a bunch of crap in a manic state about how he's going to figure out how to bring humanity to the stars! He whines about Sean Carroll some more, tells dumb stories about Jeffrey Epstein, whines about how Elon Musk won't talk to him, it really is the most glorious trainwreck imaginable. He really isn't reacting well to the whole internet figuring out what a douchebag he is. Let's point and laugh as his ship goes down in flames, yeah?

Quantum Numbers, Atomic Orbitals, and Electron Configurations

Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD you will know what they are. But let Professor Dave give you a head start!
