Gravitation: The Four Fundamental Forces of Physics #3

Gravitation: The Four Fundamental Forces of Physics #3

Welcome Back to our series on the four fundamental forces of physics. Today we are talking about gravitation, the force that you and I probably have the closest working relationship with. But it’s not only what sticks you to the ground, and makes you fall down, it also explains how stars and galaxies form, and […]

What’s the Physics Behind Texting?

You probably send a bunch of texts everyday. But when you hit send, what happens? How does your message make its way across the room or to the other side of the world, to someone else’s phone? I’m Greg, and What The Physics?! To send a message out of your phone, electricity from your battery […]

Light Is Waves: Crash Course Physics #39

Light Is Waves: Crash Course Physics #39

Here’s a question for you: If you shine a light on a coin that’s hanging in mid-air, what do you think its shadow will look like? Do you think its shadow would have a bright spot of light right in the middle of it? Because it would! It might seem counterintuitive, and 19th-century physicists thought […]

Jellyfish Lasers Are Revolutionizing Quantum Physics

Jellyfish Lasers Are Revolutionizing Quantum Physics

I am in the middle of a huge dilemma, I really don’t like jellyfish, they freak me out, but I love lasers… they’re so cool! And this new science is making lasers with jellyfish!? AHHH!! Hey photonic reflectors, Trace here for DNews. When lasers were first invented, they were called “a solution looking for a […]

Relativistic Addition of Velocity | Special Relativity Ch. 6

Relativistic Addition of Velocity | Special Relativity Ch. 6

In our universe, when you change from a non-moving perspective to a moving one, or vice versa, that change of perspective is represented by a what’s called Lorentz transformation, which is a kind of squeeze-stretch rotation of spacetime that I’ve mechanically implemented with this spacetime globe. Lorentz transformations keep the speed of light the same […]

Introduction to light | Electronic structure of atoms | Chemistry | Khan Academy

What I want to do in this video is give ourselves a basic introduction to the phenomenon of light. And light is, at least to me, mysterious. Because on one level it really defines our reality. It’s maybe the most defining characteristic of our reality. Everything we see, how we perceive reality, is based on […]

The Existence of White Holes May Settle One of Physics’ Biggest Debates

The Existence of White Holes May Settle One of Physics’ Biggest Debates

Longtime viewers of this channel know that we talk about black holes a lot. We just can’t seem to get enough of them. We give them so much attention but today we’re going to talk about their bizarro twins, white holes. Basically, a white hole is the hypothetical opposite of a black hole. Now I’d […]

Open Letter to the President: Physics Education

Dear Mr. President, Do you know much about physics? I mean, you’re the President of the United States: a country with five thousand nuclear weapons, birthplace of the world’s computing and telecommunications industry, home of the first atomic clock and creator of the global positioning system. But chances are, if you just took regular American […]
