In the previous tutorial we learned about carbenes. So now that we understand their properties, we are ready to learn about what we can do with them. Three major uses of carbenes involve cyclopropanation, C-H insertion, and the...

Upon viewing the Magnets and Electromagnets video series, students will be able to do the following: Define a magnet as a material that attracts iron and materials containing iron. Explain that magnets have a north pole and a south pole...

Lesson 14 (Rotation and Torque) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this...

It's been called "the Queen of Sciences"--mathematics. It might not be as obvious in Olympic sports as physics or materials-engineering, but math--from simple arithmetic to calculus--is part of every jump, every spin, every move the...

The reverse magnus effect - Curving and bending a ball using the magnus effect is common in soccer, tennis, and baseball. The effect can be reversed though - kick the ball the same way, and it will bend in the opposite direction!

This live-action video program is about wind turbines. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated...

What is the minimum angular speed necessary to keep water in a vertically revolving bucket? The rope radius is 0.77 m.

Contextuality might mean that there are no alternatives to Quantum mechanics that are sensible. Given Quantum isnt sensible either, there may just not be any sensible theories at all.

What is entanglement really? And why is it that its a uniquely quantum phenomena? Bohmian mechanics stuff: In Bohmian mechanics, you still have superpositions, they just mean something very different. A Bohmian mech particle only has one...

Quantum entanglement is a physical resource, like energy, that is possible between quantum systems. When a coin spins on a flat surface, it’s in a state of superposition between its two faces—head and tails. Similarly, electrons in their...

This video is based on the fantastic discussion of Bells theorem by my favourite physicist, David Mermin. Is the Moon there when nobody looks?

In this video, the teacher explains how to determine the union of two subsets of a sample space. The concept of a sample space is introduced as the set of all possible outcomes for an event. The teacher uses examples with dice and...

Tipler Cylinders? Wormholes? Ring Lasers? Is it possible to travel BACK in time? In this action packed episode, Dom is hunted down by a government agent who wants to know how he made a time machine.

Researchers in Canada are working to build an experimental Atmosphere Vortex Engine at Lambton College in Ontario. An atmospheric vortex engine, AVE, uses a controlled vortex to capture mechanical energy produced when heat is carried...

In episode 42, Jordan and fill-in co-host Laurie talk about cotton candy machines that have been repurposed to make artificial capillary networks. The artificial capillary system the researchers were able to produce using this method...

Find out what quarks are, how they were discovered and why they are very important in relation to protons and neutrons. There are different types of quarks which you'll learn about in this GCSE / K12 "Radioactivity" video from the...

Earth and Compasses Perhaps you’ve played with bar magnets or have a magnet on your fridge. But did you know that the earth is a giant magnet? In fact, this is how compasses work. In this video we’re going to look at the earth’s magnetic...

What happens when you fill a ping pong ball with extremely flammable propane, then light it on fire? Does it spin really fast, or make a cool noise, or explode? The answer is yes!



Last video, I made a mistake. I forgot to...

Over a thousand tornadoes happen every year in the United States but only few dozen take lives. Most tornadoes are brief and weak but the tornadoes that are large and powerful can wipe homes off their foundations. Tornadoes only come...

Emily Burns (Adapter and Associate Director) and Fisayo Akinade (Mercutio) in conversation about the Queen Mab speech from Romeo and Juliet. Emily and Fisayo discuss various interpretations of this scene and the choices behind how it was...

Imagine if engineers could build a computer to be millions of times faster than anything that exists today, yet so small it's microscopic. John Preskill, a theoretical physicist at the California Institute of Technology, explains the...

This video provides a basic understanding of electric motors, their purpose, and their fundamental components.<b<br/>r/>

This video is part of the 11-part series, Electromagnetism.

When you mix red and green, what do you get? White light is all of the colors, right? So, how do computer screens show you every wavelength of light? Or do they?
