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.

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...
