This video provides a concise explanation of how a light globe, or light bulb, works. It discusses the invention and history of the light bulb, as well as the science behind its operation. Understand how electricity passes through a...

All of this Trump and Kim Jong Un drama on earth is mere child's play compared to these ways that our own Universe could wipe us out today!

Space. It's the final frontier and one of the great unknowns for mankind. But you probably don't even know what you don't know about it. So sit back and find out why your 4th grade science teacher was probably completely off.

Missions to outer space have come a long way since the days of Cold War competition. Farah Alibay finds that building relationships is a big part of building spacecraft.

Movies take a lot of dramatic license where science is concerned, but who's getting it all wrong on the silver screen. From the g-force you would suffer when achieving lightspeed to what a nuclear bomb would sound like in space we...

My strategy for solving any projectile motion problem. You need to split the variables in to the x and y directions and solve for time. Sounds simple and it really is, usually.

I've always wondered what would happen if you lined up 10 megaphones in a row and yell into them, today I put that idea to the test! That literal feedback loop was crazy loud!

Cooking Dinner with Science!

Engineers at NASA’s Johnson Space Center in Houston used light waves to align the James Webb Space Telescope’s mirror segments to each other, so they act like a single, monolithic mirror in the cryogenic cold of the center’s iconic...

English is weird!! Many words don't sound the way they look and some are, indeed, very strange.



In this video I teach you how to correctly pronounce the follow

This nugget explains the discovery of International system of units. It also explains SI system in detail.

Hidden below Chamber A at NASA's Johnson Space Center in Houston is an area engineers used to test critical contamination control technology that has helped keep NASA's James Webb Space Telescope clean during cryogenic...

What happens when you shoot a ballistic ping pong ball going 450kph at a tennis ball?

Engineers lift the James Webb Space Telescopes cameras and spectrographs out of the Space Environment Simulator at NASAs Goddard Space Flight Center in Greenbelt, Maryland. These vital parts of the Webb Space Telescope endured their...

The first laboratory technique that we will learn together is a very simple one, filtration. This is how we separate a mixture of liquids and solids. There are two common ways a chemist will perform filtration, those being gravity...

Retired NASA astronaut John Grunsfeld hosts this six-part mini-series about the tools used on the Hubble Space Telescope servicing missions. Hubble was uniquely designed to be serviced in space so that components could be...

With NASA's James Webb Space Telescope's approximately nine-month stay in Texas coming to an end, this time-lapse shows activity in the NASA Johnson Space Center's Chamber A cleanroom from the arrival of the Webb Telescope's...

Lesson 17 (Waves, Light, and Sound) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you! Exercises...

In this video, we explore the science behind why we see fireworks before we hear them, and how the speed of light and sound play a role in this. We also conduct experiments to understand how sound travels through different mediums, and...

Space is a harsh environment, and building a space-bound satellite is no small feat. Here's a look at how NASA engineers get the Glory mission off the ground and safely into space.<br/>

Can anything travel faster than the speed of light? Is it even possible for something to undertake the “speed of light” travel? And what if something can actually travel faster than light? What is Cherenkov radiation and how is it...

A few more thoughts on the Nerf Cannon.

Yes, I know if I used a longer barrel I could get higher speeds, but I did not want to deal with a 20ft long gun. I think a 6ft barrel was enough to show what a supersonic nerf dart can...

The video explains the basics of electromagnetic waves, including their definition as transverse waves that transfer energy from a source to an absorber. It discusses the seven general sections of the electromagnetic spectrum, going from...

Curling has been in the Winter Olympics for four years now, but it still seems a little strange to most of us. John Shuster, the captain--or "skip"--of the U.S. Curling Team in Vancouver, explains this unusual sport, and NSF-funded...
