Professor Dave Explains

Isn't it fun when I interact with creationists live? Want to watch that for 90 minutes? Of course you do! One was very polite and barely disagreed with me, one was rather polite but refused to acknowledge his brainwashing, and one was super rude and shouting at me the whole time. Plus some other stuff. Everything you want from a call-in show! Enjoy.

For this one we will have to be able to interpret IUPAC nomenclature to draw molecular structure, including absolute configuration using the Cahn-Ingold-Prelog convention.

One thing we may want to do in algebra is compute the distance between two points on the coordinate plane. Luckily, there is a handy dandy equation for doing just that! Let's derive it first, and then practice using it.

We've been learning about the Perfect System. With present perfect and pluperfect down, the last tense to investigate is the future perfect. This is for completed actions in the future. Wait, how does that work? That doesn't make sense! It will soon, just watch!

For this one we need to understand the stereospecificity of hydrogenation over platinum metal, stereochemical relationships, and the relative stability of cyclohexane chair conformations.

By now we are experts at solving quadratics by a number of different strategies. But what about cubics? And quartics? And quintics? Seems pretty daunting, but believe it or not there is a reliable method to solve these higher degree polynomials as well. It's a little more time-consuming, but it can be done! Check it out.

With the monotremes covered, let's move on to the marsupials. These are the pouched mammals. How did these evolve? How does the patch work? Let's talk about it!

Any introductory chemistry class will include titrations, and to do these, you have to do math. But you get to see pretty colors, too! Here's a quick run through of the stoichiometry of it all.

It's time to dunk on the toxic pseudoarcheology cult some more! Today's victim is Ben van Kerkwyk, a clueless toolbox who lies about all kinds of archeological sites to sell bogus overpriced tours. Most recently his claims about "super-advanced" stone vessels were disproven by multiple researchers he hired himself, which is hilarious, so let's all laugh at this clown together, shall we?

Anti-science sentiment is taking hold of the public in a way we've never seen before. More and more people distrust any scientist because of propaganda that tells them to do so. How do we combat this? Of course we can dissect the propaganda and show people how it is deceptive. But we also have to rehabilitate public perception of the scientific community. That's where all you scientists come in! Do you want to show the world who you are, what you do, and why it's important? Submit a profile piece for my "Get to Know a Scientist" series! It's easier than you think! Watch this and shoot me an email if you think it's a good fit for you.
