The Hierarchy of Life
Paul Andersen explains how biology is ordered in the hierarchy of life. He first of all describes how emergent properties appear as you move to more inclusive systems. The then describes life at the following levels; atom, molecule,...

Magnets: How Do They Work?
How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

Why Does Everything Decay Into Lead
If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...

The Moon is Rusting. It's the Earth's Fault.
The Moon is typically 380,000-ish kilometers from the Earth, so it doesn't seem like they have that much of a direct influence on one another. However, the presence of hematite on the lunar surface suggests our planet is causing the Moon...

What Happens During a Quantum Jump?
Since the very beginning of quantum mechanics, a debate has raged about how to interpret its bizarre predictions. And at the heart and origin of that debate is the quantum jump or quantum leap - the seemingly miraculous and instantaneous...

TED-Ed: What's happening to Earth's core? | Shannon Odell
A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the...

The Sun Is Green
The Sun is green, actually. We'll go into why the blackbody effect means the Sun emits more green visible light than any other color, and why evolution and color perception mean it's ok to see it as yellow, anyway.
