By: Professor Dave Explains

Welcome! I have a knack for explaining stuff and I want to share some knowledge with you.I received a BA in chemistry from Carleton College, and performed graduate studies in both synthetic organic chemistry and science education at Cal State Northridge, receiving an MA in the latter. Prior to this I taught for about a decade in various high school and undergraduate settings, specializing in organic chemistry but also teaching general chemistry, physics, and biology.This channel is for students at the high school and undergraduate level, but it is also for members of the general public who just...

After looking at the Laplace equation and the wave equation, it's time to move on to the diffusion equation. This is a parabolic partial differential equation, and it describes systems that tend to spread out over time. This has tons of practical application, so let's get into it!

Okay, it's time to dig into quantum mechanics! Don't worry, we won't get into the math just yet, for now we just want to understand what the math represents, and come away with a new and improved view of the electron as both a circular standing wave and a cloud of probability density. Spooky! Let's introduce the Schrödinger equation!

Quantum Electrodynamics (QED)
Quantum Electrodynamics (QED) episode artwork
Today at 2:40 AM

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's why it's called quantum theory, we are showing how particles, or quanta, run the whole show. The electromagnetic force was the first one to get a facelift, so let's check out how these quantum field theories work by looking at quantum electrodynamics!

Power Series Solutions Part 2: Frobenius Method
Power Series Solutions Part 2: Frobenius Method episode artwork
Today at 2:08 AM

We just learned how to solve differential equations using power series. However the simpler approached we used assumed that all the functions involved are infinitely differentiable at the point we are expanding about. This will not always be the case, and a common workaround in situations where the previous approach does not work is called the Frobenius method. Let's see how this works now!

Reacting to Quantum Mystic "Higher Frequency" Self-Help Rubbish episode artwork
Today at 1:02 AM

Some jerk named Robert Edward Grant spewed a bunch of quantum mysticism crap about "moving into higher frequencies", which is literally meaningless, and some idiotic channel named Video Advice made a garbage animation to go along with it. What resulted was 15-minutes of nausea-inducing, transparently pseudoscientific self-help snake oil. So let's make fun of it for an hour.

Relativity comes in different flavors, as it happens. We spent some time looking at Einstein's special relativity, so now it's time for the general variety. This is all about the geometry of spacetime, which curves around massive objects. This was a huge update on our understanding of gravity, so get on board!

The double-slit experiment is a classic experiment that is frequently referred to when describing quantum phenomena, so we definitely have to go over it a little bit. What happens when you pass a beam of light through a screen with two slits? What about when you send electrons through there? Or just one electron? It's crazy stuff! Check it out.

Grayson Hawk is another excellent science communicator and debunker who tackles many of the same charlatans that I do. If you enjoyed my debunk of the delusional fraud Chris Langan and wanted me to go through the much longer video on Curt Jaimungal's channel, then just watch me and Grayson make fun of select clips from that video. Oh, we make fun of James Tour as well. It's a good time!

Yesterday at 11:20 PM

After the crisis of the third century, the later Roman Empire took shape. This period involved many different leaders, great political change, and the eventual splintering of the empire into Western and Eastern halves, the former of which would eventually dissolve, and the latter of which would become the Byzantine empire. Let's go through the details!

Yesterday at 10:30 PM

Everyone and their mom knows about E = mc^2, it's the most famous equation in science, and there are plenty of posters you can buy for your dorm room with Einstein's face and this equation floating mysteriously around his head. But what does it mean? You'd better know if you're gonna get that poster! What if that cute boy or girl from class comes over and asks you about it and you don't know what you're talking about? That will be super embarrassing. You'd better watch this.

So Max Planck kicked things off, but how does the story of modern physics continue? With none other than your favorite scientist and mine, Albert Einstein! He did more than just stick his tongue out and have crazy hair. He elucidated the nature of the photoelectric effect back while working as a patent clerk in Switzerland. Must have been a boring job, because Einstein changed the world with his wandering mind!

Pythagoras wasn't the only Greek fellow that was into math, you know.

Complex Numbers: Operations, Complex Conjugates, and the Linear Factorization Theorem episode artwork
Yesterday at 5:56 PM

In getting through algebra, we never talked about complex numbers, but they are important so let's discuss them now! These are numbers with a real component and an imaginary component, so we first have to understand what i means, in a mathematical context. It's the square root of negative one. Then we need to learn how to do arithmetic with these expressions, and finally we can understand how we get answers in this form when using the quadratic formula but with a negative discriminant. Much to discuss, check this out!

These are called Galton details, or minutiae, and they include things like ridge endings, bifurcations, and much more. Let's get a better sense of them now!
