Professor Dave Explains

After all of the forensic analysis that goes into a case, the culmination of this process is expert testimony provided in court. This is where forensic scientists present the evidence they have collected, which may incriminate or exonerate a defendant. Who can be an expert? How do they conduct themselves in court? Let's talk about all of this!

Lisa is moving again already! I dunno, I think there were bedbugs. This time you have a different plan, but you will still need kinematics and Newton's laws to find out how much time and effort stand between you and more snacks. Give it a try!

We just went over a bunch of different theorems, but we need to do one more! It's kind of neat. I don't have anything else to say, just watch this, it's really short.

With ChatGPT, Grok, Claude, and so many other models, AI, or artificial intelligence, is on the rise. It's everywhere, and it will only become more ubiquitous with time. What does this mean for humans? Beyond the economic concerns of AI replacing many or even most jobs, is AI a threat to human survival? Many scholars say that AI is an existential threat on the level of climate change or nuclear war. Why do they think this and what can we do about it? Is the AI industry doing anything about it? In this piece we will go over all of these questions and more, so watch as though our lives depend on it, because they might!

What does the word "average" mean to you? There are a lot ways we use that word, and even in math, it can imply a few different things. If we want to summarize a set of data in a meaningful way, we can talk about the mean, the median, or the mode, and one might be more useful than another in a particular context. So let's learn what these are all about!

Archeological excavation is an inherently destructive process. And for a long time, archeology was practiced unethically. One egregious practice was the taking of human remains from communities who did not want to be disturbed. Good science is ethical science, so let's take a moment to outline the proper practices of ethical archeology.

Continuing with our study of the Israelites, we reach the period known as Second Temple Judaism. This is because the Israelites were permitted to return to Jerusalem from exile in Babylon and reconstruct their temple. This is also the time when the Jewish identity arose. Let's learn more about this period now!

After we learn chemistry and biochemistry, we are ready for biology! In this course we extend our understanding of molecules to encompass an entire cell and everything inside it. This is a huge step in complexity, and we will even talk about how the first cells may have come about. First just a little introduction to whet your whistle!

With ordinary differential equations wrapped up, it's time to move on the partial differential equations. These can be trickier than ODEs, but don't worry, we will learn all kinds of handy techniques for solving them. Let's start out simply by going over the basics regarding classification of PDEs, and introducing differential operators.

If we know how to add and subtract fractions, we should know how to multiply and divide them too, right? Don't worry, it's actually even easier than adding and subtracting them, because when we multiply two fractions, they don't have to have the same denominator, like when we add them. And dividing by a fraction is the same as multiplying by its reciprocal. It's all in here, take a look!
