Professor Dave Explains

Enough of this two-dimensional, stuck in one plane rubbish! The real world has three spatial dimensions! Technically more, but we very clearly interact with three all the time, so it's time to start talking about three-dimensional shapes like pyramids and prisms and cylinders and cones, and the characteristics they possess.

Ozonolysis? Ozone is in the sky, right? That thing that shields us from UV light? That's right friend, but ozone is also used in the lab to cleave carbon-carbon double bonds. Check it out if you don't believe me.

We just learned what polynomials are, but that's not going to be enough! We have to learn how to add, subtract, multiply, and divide them. Let's start with the easy operations, addition and subtraction!

Have you seen the headlines about SpudCell? It's the newest breakthrough in synthetic biology, a synthetic cell with some interesting properties, including cell division. Is it alive? What can we learn from it? Let's go over some basic information, and then talk to Kate Adamala, the researcher behind SpudCell to get some answers!

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!

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!

Now that we have an understanding of the principles of forensic science, we can begin to examine crime scene investigation. CSI involves many steps, but the first three are protecting the crime scene, recognizing evidence, and searching for evidence. Let's go over some details regarding these three steps!

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.

Have you ever seen Bill Wurtz's "history of the entire world, i guess"? It's a freaking masterpiece. If you have seen it, watch me react to it and explain a ton of the science that he references in highly comedic rapid-fire fashion. If you haven't seen it, still watch me do that, and then go watch it again without interruptions. It's a hall of fame video without a doubt.

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?
