Richard Dawkins: Why the universe seems so strange
Biologist Richard Dawkins makes a case for "thinking the improbable" by looking at how the human frame of reference limits our understanding of the universe.

Ionic Bonding
In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...

The End of Everything
Hank gives us an inclusive overview of how everything in the universe is thought to have begun, and how cosmologists predict it will all come to an end. Now get happy!

The Microscope That Uses Quantum Physics to Trace Atoms
In the late 1970s, two physicists in Switzerland set out to invent a new type of microscope using quantum physics that would allow them to do something no one had ever done before: see the individual atoms in a sheet of metal.

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! Chapters View all...

TED-ED: Particles and waves: The central mystery of quantum mechanics - Chad Orzel
One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? Chad...

TED-ED: If matter falls down, does antimatter fall up? - Chlo_ Malbrunot
Like positive and negative, or debit and credit, matter and antimatter are equal and opposite. So if matter falls down, does antimatter fall up? Chloe Malbrunot investigates that question by placing two atoms - one made of matter, and...

TED-Ed: How many universes are there? - Chris Anderson
The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that...

TED-ED: How atoms bond - George Zaidan and Charles Morton
Atoms can (and do) bond constantly; it's how they form molecules. Sometimes, in an atomic tug-of-war, one atom pulls electrons from another, forming an ionic bond. Atoms can also play nicely and share electrons in a covalent bond. From...

When Time Breaks Down
We learned how motion gives matter its mass, but how does motion affect time? Let's dive deeper into the true nature of matter and mass by exploring Einstein's photon clock thought experiment, and the phenomenon that is time dilation.

IDTIMWYTIM Heisenberg Uncertainty Principle
The Heisenberg Uncertainty Principle might not mean what you think it means: Hank clears things up for us in this edition of IDTIMWYTIM, by distinguishing between the Uncertainty Principle and the Observer Effect, which are often conflated.

Stimulated Emission
In this video Paul Andersen explains how stimulated emission can be used to create coherent light. When an atom absorbs a photon it moves to a higher energy level through stimulated absorption. It may then release a photon and moves to a...
