Professor Dave Explains

Welcome! I have a knack for explaining stuff and I want to share some knowledge with you.

I received a BA in chemistry from Carleton College, and performed graduate studies in both synthetic organic chemistry and science education at Cal State Northridge, receiving an MA in the latter. Prior to this I taught for about a decade in various high school and undergraduate settings, specializing in organic chemistry but also teaching general chemistry, physics, and biology.

This channel is for students at the high school and undergraduate level, but it is also for members of the general public who just want to know more about the world and how things work. My goal is to increase science literacy in our society, so please share these tutorials with anyone that you think might enjoy them. Happy learning!

    Prokaryotic Cells: The Simplest Kind of Life

    We've established that the basic unit of life is the cell, and that the simplest forms of life are just one cell. The earliest unicellular organisms were prokaryotic, and there are many prokaryotic organisms still around today, including all bacteria. So let's go over the features of the prokaryotic cell!

    Alien: Covenant - How Did David Create the Neomorphs?

    By now we've hopefully all seen Alien: Covenant. If you haven't, go see it right away! It's awesome, and this has spoilers. After you've seen it, you'll probably have a few questions, just as I did. The main thing that left me wondering, was precisely HOW David did all of his genetic manipulation to create the neomorphs. His laboratory looks like a medieval dungeon, after all. Does the pathogen have sentience? What's happening on the molecular level? Beyond this, do these kinds of stories bias the public about our own efforts to attempt genetic modification? Are people afraid of GMOs because they are used to movies where the products of this kind of tinkering are killing machines with bonus mouths and acid for blood? Let's investigate the details of David's work, as well as our own, when it comes to artificial selection and genetic modification! Thank you to 20th Century Fox for providing the ALIEN: COVENANT set for this shoot! It was a lot of fun.

    The Origin of Life on Earth

    You must have wondered about it before, haven't you? How did life begin on earth? I mean the very first thing. The first unicellular organism, billions of years ago. Is it even possible? As it happens, our understanding of chemistry, biochemistry, and biology has become so sophisticated over the years, that we now have a pretty reasonable grasp as to how abiogenesis must have occurred. This is the spontaneous generation of life from non-living material. As incredible as it sounds, there is a lot of science to discuss here, so let's get into it!

    Thromboembolic Drugs Part 1: Principles of Platelet Activation

    We just looked at some drugs that regulate cholesterol biology, so now let's take a look at platelets. These are small cells that are major components of blood clot generation, so regulating these can also be useful in addressing cardiovascular disease.

    Separable First-Order Differential Equations

    Now that we know how to classify differential equations, we have to learn how to solve them. Let's start with the easiest ones to solve, separable first-order differential equations. This will involve some simple algebra and then basic calculus, so it shouldn't be tough to follow, but it will give us some good practice with starting to solve these equations.

    The Pythagorean Theorem

    This one is famous! And super ancient.

    Sean Carroll Humiliates Eric Weinstein (Piers Morgan is Also Dumb)

    Eric Weinstein loves pretending to be a physicist. This is something he is able to do on podcasts because most people can't tell that he isn't one. But real physicists can see right through him. And today we get to watch one of these real physicists, Sean Carroll, tell Eric that he isn't a physicist at all right to his smug face, over and over again. It's extremely satisfying.
