When we look at the world at the tiniest scales, things get very weird. Take a wild ride through the quantum world, from the discoveries that reveal its strange rules to the amazing technologies it unlocks – with more powerful possibilities to come.

How Atomic Clocks Keep Perfect Time

2m 15s

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks work, and how they ensure global synchronization in everything from GPS to scientific research.

The Most Baffling Idea in Physics, Explained

3m 33s

Quantum entanglement is one of the strangest and most fascinating phenomena in physics. Even Einstein didn’t believe it - he called it “spooky action at a distance” - but science has proven it true. Here’s a simple explanation of the most baffling concept in physics.

How Medieval Armorers Made Knights Bulletproof

2m 15s

A select few suits of armor were crafted with secret techniques that made them stronger than others, possibly even bulletproof. Historians and ballistics experts reconstructed the amor of an elite knight and tested its strength by shooting it with a musket.

How Do Hurricanes Form?

1m 2s

Scientists predict that our increasingly warmer atmosphere and oceans will feed these hurricanes — we may not see more of them that we used to, but the ones we do see are likely to get more and more intense.

Could Mars Have a Ring Around It One Day?

2m 16s

Phobos, one of Mars' moons, has an uncertain origin, but its surface grooves show that tidal forces are pulling it apart. In time, Mars' gravity will shatter it entirely, creating a ring of debris around the planet.
