The Higgs Mechanism Explained
Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass!
Crash Course
White Dwarfs & Planetary Nebulae
Today Phil follows up last week’s look at the death of low mass stars with what comes next: a white dwarf. White dwarfs are incredibly hot and dense objects roughly the size of Earth. They also can form planetary nebulae: huge,...

TED-ED: What is the shape of a molecule? - George Zaidan and Charles Morton
A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and...

TED: How green hydrogen could end the fossil fuel era | Vaitea Cowan
As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers...

Legitimate Cold Fusion Exists | Muon-Catalyzed Fusion
This video is about the original cold fusion: μ muon-catalyzed cold fusion of deuterium, tritium, hydrogen, into helium-3 and helium 4. The problems with it are the half-life of muons and the sticking of muons to alpha particles. Also...

TED-Ed: How epic solar winds make brilliant polar lights - Michael Molina
Why do we see those stunning lights in the northern- and southernmost portions of the night sky? The Aurora Borealis and Aurora Australis occur when high-energy particles are flung from the Sun's corona toward the Earth and mingle with...

Using Devil's Milk to Kill Superbugs
Scientists are turning to unusual places to find new compounds to fight off drug-resistant “superbugs.” The discovery came from milking ferocious mammals!

TED: To save the climate, we have to reimagine capitalism | Rebecca Henderson
Business is screwed if we don't fix climate change, says economist Rebecca Henderson. In this bold talk, she describes how unchecked capitalism destabilizes the environment and harms human health -- and makes the case for companies to...

TED-Ed: Earth's mysterious red glow, explained | Zoe Pierrat
In 2009, a satellite circled Earth, scanning and sorting the wavelengths reflecting off the planet's surface. Researchers noticed something baffling: an unexpected wavelength of unknown origin. They tried looking at Earth with only this...

5 Ways to Use Your Body as a Charger
Devices that collect data about our bodies need power, but they also might need to be very small or even ingestible. To avoid including batteries in these cases, researchers are looking for ways to harvest energy from the body itself.

Hiding a Nobel Prize From the Nazis
To keep their solid gold Nobel Prizes away from the Nazis, James Franck and Max von Laue sent their medals to trusted colleague Niels Bohr. But when Germany invaded Denmark in 1940, the medals were no longer safe - so chemist George de...

Why Can Blu-rays Hold More Than DVDs?
Blu-rays can hold about ten times more than DVDs because Blu-ray players use special blue lasers to read them. But it took a while for scientists to figure out how to make those lasers work.

From Thunderstorms to Black Holes: 4 Natural Particle Accelerators
We've been making particle accelerators for more than a century and have accelerated particles to more than 99.9999% the speed of light. But our accelerators are nothing compared to some of the ones we've found in nature!

TED-Ed: What’s the smallest thing in the universe? - Jonathan Butterworth
If you were to take a coffee cup, and break it in half, then in half again, and keep carrying on, where would you end up? Could you keep on going forever? Or would you eventually find a set of indivisible building blocks out of which...

TED-Ed: The uncertain location of electrons - George Zaidan and Charles Morton
The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus --...

Solving the Impossible in Quantum Field Theory
The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations in quantum fields. But even the most elegant and complete formulations of quantum physics - like the Dirac...
