Professor Dave Explains

In the previous tutorial we introduced the wave equation, and learned one way to solve it. Now let's look at another method for getting a solution. This will require that we brush up on dimensional analysis, so let's get to it!

We've looked at a few simple examples of first-order differential equations and how to solve them. Now let's take a look at exact first-order differential equations.

In science, we love data! But what are the rules of data collection? How accurate and how precise can we get with our data? What do these words even mean? Let's find out!

We just learned about the wave equation in one dimension, so what happens when we move to higher dimensions? What does this look like for a 2D surface, like a vibrating drum, or a 3D object, like an electron? This gets pretty fascinating!

We talked a little bit about relative motion in the classical physics course, with Galileo dropping stuff in boats. But once Einstein got his hands on relativity, he went a little nutty with it! The inertial reference frames are back but now we are talking about objects moving near the speed of light, which is where things start to get a little... weird.

Okay, we've all dreamed about exploring the universe and finding our own little cosmic vacation bungalow. But these places are really far, so how can we get there? Not the way we go through space now, that's just too slow. Are there other ways to navigate the galaxy and beyond? Let's talk about fusion engines, warp drives, and wormholes!

We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the "central dogma" of molecular biology. But how is this process regulated? How does a cell know which genes to express and when? Well it's pretty complicated, but let's just get our feet wet by looking at operons, epigenetics, and transcription factors!

Now that we know a bit about the anatomy of the bony fish, let's talk about breathing, buoyancy, and regulation. Fish need to breathe oxygen just like us. So how does that work exactly? It's quite fascinating!

Remember my live debate with Steve Kirsch and Pierre Kory, the idiot anti-vaxxer frauds? Humiliating them live was awesome, but they also deserve to have their entire histories of fraudulence exposed. This means that each of them need their own video, and this one is Steve's. Let's laugh at his delusion and incompetence together, shall we?

We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational force, so that quantum theory can be reconciled with general relativity. Sounds easy, right? Let's see where we're at with it!
