Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles – the proton, neutron and electron – come together in trillions of combinations to form … everything. We start out with one of the biggest ideas in chemistry ever – stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.
Jacob and Adriene launch a brand new Crash Course on Economics! So, what is economics? Good question. It’s not necessarily about money, or stock markets, or trade. It’s about people and choices. What, you may ask, does that mean. We’ll show you. Let’s get started!
And thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert Lewis? It’s all contained within.
