Biomaterials: Crash Course Engineering #24

From Crash Course. We’ve talked about different materials engineers use to build things in the world, but there’s a special category of materials they turn to when building things to go inside our bodies. In this episode we’ll explore the world biomaterials like titanium and their coatings, the special chemistry of polyurethane, and the cross-linked…

The Mighty Power of Nanomaterials: Crash Course Engineering #23

From Crash Course. Just how small are nanomaterials? And what can we do with stuff that small? Today we’ll discuss some special properties of nanomaterials, how some can change at different sizes, and the difference between engineered nanomaterials and ones that occur naturally. We’ll also talk about some of the future research that’s needed on…

Supervised Machine Learning: Crash Course Statistics #36

From Crash Course. We’ve talked a lot about modeling data and making inferences about it, but today we’re going to look towards the future at how machine learning is being used to build models to predict future outcomes. We’ll discuss three popular types of supervised machine learning models: Logistic Regression, Linear discriminant Analysis (or LDA)…

Thermodynamics: Crash Course History of Science #26

From Crash Course. It’s time to heat things up! LITERALLY! It’s time for Hank to talk about the history of Thermodynamics!!! It’s messy and there are a lot of people who came up with some ideas that worked and other that didn’t and then some ideas that should have come first actually were figured out…

Silicon, Semiconductors, & Solar Cells: Crash Course Engineering #22

From Crash Course. Today we’re looking at silicon, and how introducing small amounts of other elements allow silicon layers to conduct currents, turning them into semiconductors. We’ll explore how putting two different types – N and P semiconductors – together gives us electrical components like diodes, transistors, and solar cells. Crash Course Engineering is produced…

Chekhov and the Moscow Art Theatre: Crash Course Theater #34

From Crash Course. Get ready for Russian modernism. Mike is teaching you about the playwrighting of Catherine the Great, Anton Chekhov’s plays, the Moscow Art Theatre, and the acting theories of Stanislavski. It’s all very real, and very modern. From a Realism and Modernism perspective. Crash Course is on Patreon! You can support us directly…
