This video explains how to find the volume of a frustum and explains what a frustum is. We also explain how to find the radius of the smaller/removed cone. There are two practice questions at the end of the video.

This video explains the different parts of a circle such as the arc, segment and chord. Practice questions and answers are at the end of the video.

This video explains how to find the area and circumference of a circle using the radius or the diameter.

In this video, the teacher explains how to find the volume of a cylinder using its radius and height. They guide the viewer through the steps, including identifying the radius and height, and using the formula πR^2h to calculate the...

Pi (π) is a fascinating number with many applications in mathematics, physics, and engineering. Its infinite decimal representation is a reminder of its fundamental nature in the universe. Mathematician Johann Lambert proved that pi is...

Quantum physicist Artur Ekert (Oxford and NUS) highlights the importance of having an alphabet for encoding written messages.

Nobel Laureate David Politzer (Caltech) describes how physicists use perturbation theory to describe what happens at the interface of two different surfaces.

Let's learn about how BIG the universe is!

“Greek Architecture: The Column” will explain the different types of columns used by the ancient Greeks and their influence on U.S. government buildings.

A lot of techniques and methods used in neuroscience have been developed thanks to modern technology and science. But what did neuroscientists do back in the day before all this fancy stuff? Well, turns out the giant squid axon was...

In this video, the teacher explains how to find the volume of a cone using the formula 1/3 * π * r^2 * h. They walk through the process step-by-step and provide helpful tips for identifying the values needed for the equation....

Yes, it is theoretically possible to use telescopes to see if the moon landings were real, but practically no. It would take an incredibly powerful telescope to see signs of moon landings on the lunar surface, and even the best...

This video shows how to build a simple refracting telescope, also called a monocular or a spyglass, using two lenses. One lens is double convex (converging) and one is double concave (diverging). This results in a magnified right-side-up...
