- Solving Quadratics by Completing the Square
Now we know how to factor polynomials, but sometimes that just won't work. We need a different method that might seem a little trickier, but it works every time! It's called completing the square, and it might sound like geometry, but it has to do with manipulating an expression to generate a polynomial that is a perfect square. What am I doing explaining it to you here, just watch the darn thing!

12 min - Eric Weinstein is Still Pretending He Isn't Pointless
Use code professordave at https://incogni.com/professordave to get an exclusive 60% off!
Guess who's still trying to pretend he isn't a pointless propaganda-peddling loser? Eric Weinstein! He recently went on Joe Rogan for the gazillionth time, where he spewed a bunch of crap in a manic state about how he's going to figure out how to bring humanity to the stars! He whines about Sean Carroll some more, tells dumb stories about Jeffrey Epstein, whines about how Elon Musk won't talk to him, it really is the most glorious trainwreck imaginable. He really isn't reacting well to the whole internet figuring out what a douchebag he is. Let's point and laugh as his ship goes down in flames, yeah?

1 hr 20 min - The Chemical Bond: Covalent vs. Ionic and Polar vs. Nonpolar
Ionic Bond, Covalent Bond, James Bond, so many bonds! What dictates which kind of bond will form? Electronegativity values, of course. Let's go through each type and what they're all about.

7 min - Echinoderm Diversity Part 3: Classes Echinoidea and Holothuroidea (Sea Urchins and Sea Cucumbers)
To finish things up with Echinodermata, we will look at class Echinoidea, the sea urchins, and class Holothuroidea, the sea cucumbers. What are these spiny things we call urchins? What is their anatomy like? What the heck is a sea cucumber? These are fascinating creatures, so let's learn about them!

14 min - The Periodic Table: Atomic Radius, Ionization Energy, and Electronegativity
Why is the periodic table arranged the way it is? There are specific reasons, you know. Because of the way we organize the elements, there are special patterns that emerge. And you know how Professor Dave feels about patterns. He likes them.

13 min - Quantum Numbers, Atomic Orbitals, and Electron Configurations
Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD you will know what they are. But let Professor Dave give you a head start!

13 min - Collection and Preservation of Crime Scene Evidence
After properly documenting evidence, it's time to collect it for further analysis. How is this done? There is very strict protocol for keeping all evidence separate, and properly recording precisely where it came from, so let's get some more details on this process.

14 min - Practice Problem: Inelastic Collisions at the Skating Rink
If you're strange enough to hits cats with pendulums, you're strange enough to throw frisbees at the skating rink. As you do this, you realize it's a great time to practice your physics, since you know about inelastic collisions. How much velocity can be transferred from the frisbee to your body? Only one way to find out!

About Professor Dave Explains
From the publisher's feed
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 want to know more about the world and how things work. My goal is to increase science literacy in our society, so please share these tutorials with anyone that you think might enjoy them.
