Professor Dave Explains

The first era of Indian civilization that left a written record behind is known as “Vedic” because it produced the Vedas, which is Sanskrit for “knowledge”. These are the earliest works composed in Sanskrit and the oldest texts of Hinduism. Let's examine the Vedic period, including its four varnas, or classes, and the organization of various states in the region over a millennium or so.

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.

Remember Avi Loeb? The Harvard astronomer turned pointless grifter who never shuts up about how everything is aliens? He's up to his old tricks again! He's making garbage YouTube content, he's knee deep in UAP psyop slop from the White House, and most importantly, he's whining a whole lot about me! That's right, he saw my first two videos exposing him for the worthless fraud that he is, and he's not too happy about it. Let's jump back into Avi's world for a bit!

In science, sometimes we have to talk about very large and very small numbers. We need a special way to do this called scientific notation. We also need a way to convert between different units of measurement. I know, I know, you hate math. But it's really easy math, and Professor Dave will help make it even easier!

To examine reptile diversity, let's start by looking at turtles, tuataras, and crocodilians. What is a turtle shell made of? How many kinds of turtles are there? What's the difference between alligators and crocodiles? What the heck is a tuatara anyway? So much to discuss!

That's enough with shapes, let's get back to equations and variables! I know you've missed it so. Jumping back into algebra, the first thing we want to do is understand what a function is, as this will be the main algebraic construct we concern ourselves with from now on. Let's learn what a function is, and what we can do with them.

Remember when I went on Godfrey's podcast to humiliate flat earther Lord Jamar? And then the other time when I went on there to explain a bunch of basic science for fun? Now it's time for something in between. Godfrey and his guests were espousing moon landing denial in a recent episode. Dante invited me on the show to debunk their talking points and explain some more science. It was a fun productive time, check it out!

At this point it is common knowledge that Eric Weinstein is a pointless fraud paid by Peter Thiel to spew propaganda all over the internet. As so many of us have long suspected, Sabine Hossenfelder is exactly that as well. This was made abundantly clear when Sabine recently joined the Eric Weinstein damage control parade after his embarrassing encounter with Sean Carroll on Piers Morgan, and then my video with Christian Ferko even further exposing GU as absolutely nothing and the details of his Perimeter Institute visit. But just in case that wasn't enough to convince you, allow me to take you through some of her other very recent content to demonstrate how her disgusting rhetoric is 100% aligned with Eric's script and Thiel's agenda.
