Why These 5 Rocks Actually Glow
If you're lucky enough to find a glowing rock, it likely doesn't mean you're the chosen one. In fact, it could have to do with one of these five phenomena! Learn about the quantum mechanics of glowing rocks in this new SciShow Episode...

How Quantum Mechanics Affects Your Life
While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face!

Why String Theory is Right
Some see string theory as the one great hope for a theory of everything - that it will unite quantum mechanics and gravity and so unify all of physics into one glorious theory.

The more general uncertainty principle, beyond quantum
The general uncertainty principle, about the concentration of a wave vs the concentration of its fourier transform, applied to two non-quantum examples before showing what it means for the Heisenberg uncertainty principle.

Some light quantum mechanics (with MinutePhysics)
An introduction to the quantum behavior of light, specifically the polarization of light. The emphasis is on how many ideas that seem "quantumly weird" are actually just wave mechanics, applicable in a lot of classical physics.

Feynman's Infinite Quantum Paths
There is a fundamental limit to the knowability of the universe. The Heisenberg uncertainty principle tells us that the more precisely we try to define one property, the less definable is its counterpart. Knowing a particle's location...

Why Quantum Information is Never Destroyed
If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang? Is the entire history of the universe perfectly knowable? Or has information somehow lost...

Noether's Theorem and The Symmetries of Reality
Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And yet they're wrong - or at least they're only right sometimes. These laws are consequences of a much deeper, more fundamental...
