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!

If you’re into unique gifts, premium books, or just love going down rabbit holes, this one’s for you. Remember Bart Sibrel, the worthless fraud who has spent his entire adult life spreading lies denying the achievements of the Apollo missions in sending humans to the lunar surface? And who should only be remembered as that guy Buzz Aldrin punched in the face one time? Well he's back for more punishment! He went on Piers Morgan and humiliated himself. Then astronaut Charlie Duke said some stuff, as well as William Shatner for some reason. Let's watch and laugh together!

    Well, this is weird. What are all these squiggles?

    The Evolution of Populations: Natural Selection, Genetic Drift, and Gene Flow

    After going through Darwin's work, it's time to get up to speed on our current models of evolution. Much of what Darwin didn't know is now known and understood very well, so we can meticulously go through much of the evidence we see for evolution, as well as some of the ways that it propagates other than natural selection.

    Ky Dickens Tried to Censor My Telepathy Tapes Debunk

    Last month I debunked a garbage podcast called The Telepathy Tapes, along with Ky Dickens, the grifter behind it. She wasn't too happy about it, so she tried to get my video banned from YouTube. She was unsuccessful, and only brought more attention upon herself, since it turns out that this behavior is a pattern for her. Let's talk to Janyce Boynton, a previous recipient of Ky's attempts at censorship, and get some more clarity on who Ky is and what she's doing.

    Manipulating Rational Expressions: Simplification and Operations

    Are you tired of algebra yet? Come on, it's fun! Before we dive into graphing, let's just do a little bookkeeping with rational expressions. We have to be able to easily simplify, add, subtract, multiply, and divide these, otherwise the more complex algebra that comes later will be impossible. Don't worry, it's not too bad!

    Practice Problem: Comparing Gravitational Forces

    Gravity is mysterious, isn't it? If all matter exerts gravity, why don't we all just drift towards each other all the time? Well, as you know, it depends on the masses of the two objects and the distance between them. Your friend says that she exerts more gravity on you than a nearby star. Is that possible? Stars are so massive! But they're also so far away. Let's do some calculations and see what we can come up with.

    RFK Jr. is Dangerously Stupid

    Go to consensus.app for a new way to search through primary scientific literature! Science denial is dangerous no matter who is promoting it, but it's ten times worse when it's coming from people in positions of political power. In February, RFK Jr. was appointed by Donald Trump to act as Secretary of the Department of Health and Human Services, which oversees CDC, NIH, and FDA. Bobby also is famous for profiting from spreading lies about vaccines, denying the germ theory of disease, and just generally being a complete maniac masquerading as someone who cares about public health, largely coasting off of his family name. It's time for everyone to see exactly who this guy is, and this video will be an extremely detailed analysis of his views, behavior, and the policies he has enacted during his very short time in office.
