Professor Dave Explains

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.

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive, not to mention what makes nuclear fusion reactors our best hope for clean energy in the future.

We just introduced the weak interaction, or weak nuclear force, from the perspective of quantum field theory. But there's more to discuss about this force. Why does it violate CP symmetry? What are physicists doing today to continue studying this force? Let's find out!

What is geomatics? Why it's the branch of science that deals with the collection, analysis, and interpretation of data relating to the earth's surface. How is it done? Well we've got Nigel here to tell us all about it! You may know about LIDAR if you're an archeology buff, but that's only part of the story!

Reflexive pronouns refer back to the subject of the clause they are found in, meaning they refer to the doer of the action. In English we use them when we say things like "I blame myself". How does this work in Latin? Let's find out!
