Atoms don't just appear and disappear into thin air, you silly goose. What are you, a magician? When we have a chemical equation we will have to balance it. Here's how to do it!

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!

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.

Now that we know what functions are, what can we do with them? Can we do operations with them? Yes! Can we plug functions into other functions? Yes! Oh, what won't these functions do? Let's play with a few of them now.

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.

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!

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!

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!
