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!

    Russ Vought is Destroying American Science

    It's no secret that Trump, along with evil henchmen such as Bobby Kennedy, are actively trying to destroy the American scientific community. But a new ruling was just proposed that will genuinely finish the job if it goes through. This is happening courtesy of the Director of the United States Office of Management and Budget, or OMB, whose name is Russell Vought. Don't know who that is? That's a huge problem. Does Project 2025 ring a bell? Watch this video and be amazed at the level of authoritarianism that is currently being enacted. Get very angry about it.

    Kinetic Molecular Theory and the Ideal Gas Laws

    I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Like Boyle's Law, Charles's Law, Avogadro's Law, and more! Let Professor Dave run you through the details.

    Ablative of Manner (Ablativus Modi)

    After learning the ablative of means and the ablative of accompaniment, it's time to learn the ablative of manner, or ablativus modi. This is used to answer the question "how?" or "in which manner?" In other words, it describes the way something is done or is taking place. Let's see how it works!

    Discussion With Planet Peterson (2026 Bingo Card Revisited + Science Optimism)

    It's time to check in with fellow bearded debunker Planet Peterson! Together we will go over the recent 2026 bingo card predictions made by myself and Mr. Beat in a previous video, since some of them have already been validated. Then we will try something new and get optimistic for a change! Some recent discoveries and innovations in science are really awesome, and they deserve a day in the sun just as much as the science denial we debunk, so let's talk about some good stuff too.

Those are Stephen Meyer, James Tour, and John Lennox.

    Will Synthetic Vitamins Make Me Explode?

    This was my final submission for the American Chemical Society's ChemChamps contest in 2015. The words natural and synthetic are thrown around a lot these days, when talking about foods, medicine, and other things. But what do they really mean, and how are they different?

    Ancient India Part 2: The Vedic Period (1500 – 500 BCE)

    The Cell Cycle and its Regulation

    Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad. Luckily, cells obey something called the cell cycle, which is regulated by a variety of signaling molecules, which tell the cell when to divide and when to chill out. Let's look at the phases of this cycle and some of its regulatory mechanisms now.
