Professor Dave Explains

Alright, so we've learned a lot about the origin of life. We learned about how the first organic molecules can have formed spontaneously, and how they might have assembled into the first protocell. From there, endosymbiotic theory tells us how these merged to form more complex eukaryotic cells. But these are still organisms made of one cell. Animals like humans are made of trillions of cells. So how did life make the big leap from one cell to many cells? To answer this, it is helpful to look at embryonic development, because the way one cell eventually becomes an entire animal can tell the story of how life stumbled upon this possibility in the first place. Crazy stuff!

There's a thing with carbon and hydrogen in it. But how many of each?! That's the kind of thing a chemist should know. So let's do some elemental analysis!

It's no secret that Trump, along with evil henchmen such as Bobby Kennedy, are actively trying to destroy the American scientific community. But a new ruling was just proposed that will genuinely finish the job if it goes through. This is happening courtesy of the Director of the United States Office of Management and Budget, or OMB, whose name is Russell Vought. Don't know who that is? That's a huge problem. Does Project 2025 ring a bell? Watch this video and be amazed at the level of authoritarianism that is currently being enacted. Get very angry about it. Then get loud and voice your concerns using the links below.

I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Like Boyle's Law, Charles's Law, Avogadro's Law, and more! Let Professor Dave run you through the details.

After learning the ablative of means and the ablative of accompaniment, it's time to learn the ablative of manner, or ablativus modi. This is used to answer the question "how?" or "in which manner?" In other words, it describes the way something is done or is taking place. Let's see how it works!

Chemistry doesn't always work perfectly, silly. Molecules are left over when one thing runs out! Also we never get all of the products that we thought we might by doing the math. You gotta know about the limiting reagents and the percent yield! Don't worry, it's as easy as bologna sandwiches.

Alright, now that we know what polynomials are, it's time to learn how to solve them! But how can we do that? There's terms of different degrees, it's a mess! Well as it turns out, there are a few techniques we can learn, and let's start with factoring.

How did the Ancient Romans eat? How did it differ between wealthy elites and peasants? Fortunately by reading works from people like Petronius, we can know a lot about what the Romans ate, as well as when, and with whom. Let's take a look!

It's time to check in with fellow bearded debunker Planet Peterson! Together we will go over the recent 2026 bingo card predictions made by myself and Mr. Beat in a previous video, since some of them have already been validated. Then we will try something new and get optimistic for a change! Some recent discoveries and innovations in science are really awesome, and they deserve a day in the sun just as much as the science denial we debunk, so let's talk about some good stuff too.

Planet Peterson also makes great debunking content, check out his channel and subscribe: https://www.youtube.com/@planetpeterson2824

Yes, I know moles are adorable furry creatures. This is a different kind of mole! A numerical mole. And we need to understand them to be able to make predictions about reactions. Let Professor Dave take you through the finer points.
