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!

    Third Person Pronouns in Latin (is-ea-id)

    We've learned about first and second person pronouns, so let's look at third person pronouns, is-ea-id. Apart from being pronouns these are also used as demonstrative adjectives, so let's learn how to use these!

    Graphing Lines in Algebra: Understanding Slopes and Y-Intercepts

    Now that we are familiar with the coordinate plane, it's time to learn more about lines, as these are the simplest things to graph.

    Phylogeny and the Tree of Life

    Alright, we've learned about how unicellular organisms came to be, how they became multicellular, and then from those how evolution by natural selection produced all the species in the world today. But there are so many! Millions and millions in fact. Which is most closely related to which? When did each evolve? What about all the ones that are gone? How do we keep track of this?! Ok calm down, friend. There is a whole discipline called taxonomy that we use to keep track of the phylogeny of every species. To see how it works, we look at the tree of life!

    The High Middle Ages Part 2: Crusades and Inquisitions

    After examining the changes in government and economics during the High Middle Ages, let's turn to the religious and ideological conflicts of the period. Tensions were increasing between the Christian and Muslim worlds, and there were also conflicts with the various sects of Christianity. This led to the Crusades as well as the first of several inquisitions. This stuff can get pretty gruesome, but let's dive into it.

    Practice Problems: Labeling Carbons

    What's with this hierarchy? Primary, secondary, tertiary... can't all carbons be equal? Well, no. We need to be able to label the degree of substitution of any carbon in an organic molecule so that we can make predictions about the chemistry that can occur.

    Discussion on the Science Counterpunch Podcast (The Urgency of Science Communication)

    Dave appears on the brand new Science Counterpunch podcast with co-hosts Sam Gregson and Philipp Markolin. You may recognize Sam from his channel Bad Boy of Science, and from his contribution to one of my videos exposing Sabine Hossenfelder. And you may recognize Phil from my video debunking the COVID lab leak conspiracy, which was a collaboration that would be impossible without his research and command of the topic. These guys are the real deal, they know how urgent it is to address science denial in its myriad forms. So join us for a discussion on how to best do precisely that.

    Mendelian Genetics and Punnett Squares

    For all of human history, we've been aware of heredity. Children look like their parents. But why? When Gregor Mendel pioneered the field of genetics, he began to try to answer that question, and now that we know about chromosomes, all of his work will make a lot of sense. Let's take a look at Mendel's work, his laws of segregation and independent assortment, and try to understand what these mean for genetics and inheritance.
