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!

    Solving Exponential and Logarithmic Equations

    Now that we know how to use logarithms, we are ready to solve a whole new class of equations that we couldn't before! Whether these are logarithmic equations or exponential equations, using logs will allow us to get the answers we need.

    What is Light? Maxwell and the Electromagnetic Spectrum

    Up until a couple centuries ago, we had no idea what light is. It seems like magic, no? But there is no magic in this world, really. Just stuff we don't understand. So let's understand light a little better right now, through James Clerk Maxwell and the electromagnetic spectrum.

    COVID Origins: Debunking the Grift, Pseudoscience, and Politics of the Lab Leak Theory

    Remember the COVID-19 pandemic? That was crazy, right? And did you hear that the virus responsible, SARS-CoV-2, leaked from a virology lab in Wuhan? And that it may even have been deliberately leaked to act as a bioweapon? You definitely heard that. Everybody has. But is it true? Well... I mean what's the alternative? All those stupid scientists talking about how it almost certainly originated from a wet market, with live animals coughing and crapping everywhere, just like so many other documented spillover events, what sense does that make? Those people are stupid establishment shills, right? Well, why don't we talk about it in excruciating detail for a couple hours?

    Reacting to Braindead Apologist on the Origin of Life

    Today we are reacting to some jerk named Don Batten who really hates the idea that life on Earth came about by natural processes, because it contradicts his baseless religious ideology regarding a magic sky daddy making humans super special just the way they are 6,000 years ago. He has a cute little script to try and discredit this possibility, and if you thought James Tour was stupid, you'd better buckle up.

    Standing Waves and Harmonics

    Not all waves travel across the ocean or across the universe. Some are stuck in a certain spot! Like the vibrations of the strings on a guitar. What's the deal with these standing waves? And what's this, quantization? Oh my! We'd better learn about this concept before digging into modern physics.

    After learning about the Shang Dynasty, it's time to move on to the Zhou Dynasty. This will include the Western Zhou of the 11th through 8th centuries BCE, as well as the Eastern Zhou, which includes the Spring and Autumn period and Warring States period of the 8th through 3rd centuries BCE.

    Andrew Jackson: Founder of the Democratic Party (1829 - 1837)

    President #7 represents a huge shift in American political history. The first six were educated members of the upper class, but Jackson was a commoner, elected on a wave of populist enthusiasm. He was also the founder of the modern Democratic Party. Was he a champion for the common man? Was he just a racist bigot? Was he somewhere in between?

    Newton's Law of Universal Gravitation

    You thought we were all done with Newton, didn't you? You figured that three laws are enough for any scientist. Well think again! Newton was quite the champ, and his work with gravity was revolutionary. I mean, the guy invented calculus so that he could do his work on gravity. So when he INVENTED CALCULUS, he did it just so that math could exist that was complicated enough to do stuff that was more important than inventing calculus. Think about that for a while.
