Lasers are known to burn things, fix eyes, and dance on powerpoint presentations. But they can also be used to cool objects to some of the coldest temperatures in the universe.

A distributed load is a force per unit length (N/m). The steps are:

1) draw th
e FBD
2) replace distributed load, w with a point force located at the centroid of the distri
buted load
3)
find reactions
4) make a cut...

In this video, Kanbara-sensei will introduce you to Japanese Counters! Open description to read the counter systems used in the video! The first counter system you'd want to start learning is 1 - 一つ (hitotsu) 2 - 二つ (futatsu) 3 - 三つ...

We didn’t always know exactly what the atom looked like. Even today we’re not entirely sure – but we have a far better idea than ever before! In this video, we’re going to...

This video provides an introduction to the animation technique of rotoscoping, explaining how it is used to create realistic action and special effects in movies and animated shows. It discusses the history of rotoscoping, from its...

Look, up in the sky, it's a particle! It's a wave! Actually it's both. It's light! How do we know about this stuff? Well, because of Einstein for one. He did more than E = mc^2, you know. But don't stare at the sun to see for yourself,...

This is a video discussing the differences between beams and columns in structural engineering. The video explains that while all columns are beams, not all beams are columns, as columns can only experience compression while beams can...

The physics behind rainbows and surprising facts about rainbows.

Overview of the concept of refraction of light.

This video is a lesson on reflection in spherical mirrors, using everyday objects like spoons to explain the concepts. The teacher covers technical terms such as center of curvature, radius of curvature, and focal length, and explains...

This video is a lesson on bending stress and how it relates to the internal forces acting on beams. The video explains what bending stress is, the different types of normal stresses, and the concept of moments as a measure of rotation....

In this video the focus is on where and why concave mirrors are used, as well as the image formation and types of images. Students will learn that concave mirrors are used in many ways to magnify objects, create real and virtual images...

The video is a lesson on the relationship between stress and strain and how it is represented graphically in a stress-strain diagram. The video explains the definitions of stress and strain and how they relate to internal and external...

This is a video about the behavior of light and the concept of reflection. It covers the laws of reflection, types of mirrors, and the difference between specular and diffuse reflection.

We've talked a lot about light microscopy, but this technique has inherent limitations in resolution and magnification. The next paradigm in microscopy that emerged in the middle of the 20th century was electron microscopy. Because...

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...
