We use a prism to split white light into its constituent colours. Light is passed through a slit in a screen before it hits the prism. The prism refracts the light and we can see the different colours. A second slit can be used to see...

Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

Doomed neutron stars whirl toward their demise in this animation. Gravitational waves (pale arcs) bleed away orbital energy, causing the stars to move closer together and merge. As the stars collide, some of the debris blasts away in...

Imagine having the ability to manipulate light waves in order to see through a skull right into the brain, or being able to use lasers to diagnose a bacterial infection in a matter of minutes. At the Center for Biophotonic Sensors and...

We create a Rubens\u2019 Tube to demonstrate the movement of sound waves. A tube lined with holes is filled with propane and connected to a speaker. We light the gas coming from the holes and play different frequencies and volumes of...

We look at how a vacuum affects how sound travels. An alarm is set off and placed under a bell jar. The air is removed from the jar to create a vacuum. We can still see the hammer of the alarm clock moving, but cannot hear the sound....

Since its inception in 1958, NASA has relied exclusively on radio frequency (RF)-based communications as the only viable medium for exchanging data between a mission and a spacecraft. Today, with missions demanding communication with...

This video is about two-photon (gamma-gamma) physics, and how photons can interact with each other - either mediated by a passing lepton, or gravitationally via lensing, or via vacuum fluctuation pair production of vertical particles...

These days it seems almost trivial to cool atoms down to near absolute zero temperatures in a lab, but what is the lowest possible naturally occurring air temperature on this planet?

Summary: Albert Einstein described Entanglement as “spooky action at a distance,” where doing something to one of a But it's not spooky action at a distance, at all. So what is entanglement? Electrons have a quantum property called spin...

Alcubierre warp drive - faster than light travel? Is Warp speed possible? Enterprise from Star Trek can go 9000 times the speed of light. By comparison, the fastest manmade object, the Juno probe goes 0.0002 times the speed of light. At...

The undergraduate curriculum for physics and electrical engineering have some similarities that students may not be aware of. With both majors you get to see circuits, basics physics concepts, and even electromagnetic waves. Physics...

Physics majors study the universe, from electrons and protons to supergiant stars. As a physics major you will take A LOT of math and apply complex formulas to the problems at hand. Physics majors don't just learn the equations that...

Will Coronavirus Go Away in the Summer? - TLDR News

Our part 2 video of "What does a physics major do" covers what research positions and jobs a physics major could go into. In the video I focus mostly on jobs that directly apply to physics. What you'll find is that there are an endless...

Bob Lazar and area 51. Element 115. Could the fluxliner or alien gravity propulsion system work? In a 2018 Netflix documentary, Bob Lazar claims to be a physicist who worked for a very secret site called S-4, near Area 51. His job was to...

Have you ever wondered what are X-rays used for in medicine? And how do they work? Are X-rays dangerous? In this video, we will be answering all the lingering questions you may have about this popular medical imaging technique....
