This Crystal Is ELECTRIC
There's a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric. Here's a demo from the SciShow Rocks Box where you can see this for yourself - all...

How Black Holes Spin Space Time
If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes. Black holes are self-sustaining holes in the...

Why the Muon g-2 Results Are So Exciting!
When a theory makes a prediction that disagrees with an experimental test, sometimes it means we should throw the theory away. But what if that theory has otherwise produced the most successful predictions in all of physics? Then, that...

How the Higgs Mechanism Give Things Mass
Fermilab physicists really care about the mass of the W boson. They spent nearly a decade recording collisions in the Tevatron collider and another decade analysing the data. This culminated in the April 7 announcement that this obscure...

Could We Decode Alien Physics?
How hard can it really be to decode alien physics and engineering? It’s gotta map to our own physics - I mean, we live in the same universe. We start by noticing that the alien technology seems to use good ol’ fashioned electronics, even...

What Makes The Strong Force Strong?
Quantum mechanics gets weirder as you go to smaller sizes and higher energies. It’s strange enough for atoms, but positively bizarre when we get to the atomic nucleus. And today we’re going nuclear, as we dive into the weird world of...

Why String Theory is Wrong
There’s this idea that beauty is a powerful guide to truth in the mathematics of physical theory. String theory is certainly beautiful in the eyes of many physicists. Beautiful enough to pursue even if it’s wrong? Hermann Weyl once said,...

Black Hole Harmonics
When physicists talk about black holes they’re usually referring to highly theoretical objects – static, unchanging black holes viewed from “infinitely” far away. This makes everything clean and simple enough to attempt the already...

5 Measurements You Might Not Realize Are Named After Scientists
Units are a major way we describe the world around us, and by looking at the scientists some of them are named after, we can get a sense of how we’ve learned so much about our universe.

TED: An 8-dimensional model of the universe | Garrett Lisi
Physicist and surfer Garrett Lisi presents a controversial new model of the universe that -- just maybe -- answers all the big questions. If nothing else, it's the most beautiful 8-dimensional model of elementary particles and forces...

The Black Hole Entropy Enigma
Black Holes should have no entropy, but they in fact hold most of the entropy in the universe. Let's figure this out.

Secrets of Snow | Compilation
Winter is upon us, and for many that includes snow! And although snowflakes are ice crystals that become flakes under the right conditions, they also have mysteries that can be less simple to explain!

Quantum Invariance & The Origin of The Standard Model
Our laws of physics are equations of motion, along with some associated constants. We've talked about the symmetries of these equations, and how they lead us to conserved quantities. But this is just the tip of the theoretical iceberg -...

Electric Force
In this video Paul Andersen explains how electric force on an object inside a field can be calculated by multiplying the charge of the object (in C) times the electric field strength (in N/C).

The Ghostly Particles That May Have Unbalanced the Universe
Almost all matter in the universe should have been annihilated shortly after the Big Bang, but looking around, we see galaxies, stars, planets, and, you know... us. So obviously that didn't happen, and the why of it may have something to...

The Physics of the Weird and Wonderful Theremin
Electronic music is older than you may think. Enter the theremin - a device that turns your body into part of a capacitor, and allows you to play music without even touching an instrument!

Quantum Physics in a Mirror Universe
When you look in mirror, and see what you think is a perfect reflection, you might be looking at universe whose laws are fundamentally different.

Conservation of Nucleon Number
In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...

Positive and Negative Charge
In this video Paul Andersen explains how all objects contain positive and negative charge. Neutral objects contain an equal amount of positive and negative charges. Charged objects have more positive or negative charges. Like charges...
