One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute! In this episode, we discuss the basic nature of gravity, one of the four fundamental forces in our universe.

In this episode, we discuss Dark Matter, an exotic type of matter we know very little about, despite the fact that it makes up around 80% of all matter in the universe!

In this episode, we discuss the Wave Particle Duality and why quantum mechanics is weirder than anything we're used to in our daily lives!

In this episode, I revisit the wave particle duality and present an intuitive analogy for understanding how it works. Plus, new music by Nathaniel Schroeder!

In this episode, we learn about how the sun can burn for billions of years without running out of fuel.

In this episode, we talk about the Heisenberg uncertainty principle and how it's not really that weird - it's just a property of waves!

This episode is a little bit different from the norm, because I've created the sound of hydrogen - or, that is, what if it would sound like if it emitted sound instead of light waves!

In this episode we explain what quantum tunneling is and how it works!

In this episode we take a break from physics and do a little fuzzy math. But not really: this is actually relevant to physics! Come back and I'll explain later.

In this tutorial I show how I synthesized the sound of hydrogen for the "Sound of Hydrogen" video (S2011E07) using mathematica - it's a little technical, but you've been requesting it!

In this episode we talk about dimensions and how we know that we live in 3D (or do we?).

Time is shorter than you think! In this episode we talk about distance in space and time and answer "How far away is tomorrow?"

Fire it up! We explain hot stuff. In this episode we explain why fire is red, gas flames are blue, and why you're too cool to glow.

How does physics deal with infinity? In this episode we explain how physicists can tease information out of infinity.

No cats were harmed in the making of this video. In this episode we discuss Schrödinger's cat, quantum entanglement, and our perception of reality.

Guest narrator Sean Carroll of Caltech describes dark energy and the acceleration of the universe, the discovery of which was awarded the 2011 Nobel Prize in Physics on October 4th.

Pink doesn't exist!

How does light speed up after leaving glass or water? What do light and the President of the United States have in common?

You can break the speed of light in your back yard! (but don't worry, Einstein is still right)

GPS is just a big clock in space! (and it can detect nuclear explosions)

Why is the past different from the future? Caltech physicist Sean Carroll explains how the arrow of time is not an intrinsic property of physics, but rather an emergent feature.

A million dollars is a ton of money. But how much does it weigh?

Ever tried to comb a hairy ball? Math says you failed!

November 30 Colloquium at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario. Thanks to Neil Turok for inviting me to speak!

How does a laser really work? It's Bose - Einstein statistics! (photons are bosons)

Teach your teacher: the collapse of the Tacoma Narrows bridge WASN'T resonance. And I defer all arguments to the elocution of Profs. Billah and Scanlon: http://www.ketchum.org/billah/Billah-Scanlan.pdf

Neutrinos are the vampires of physics.

Come with us to Italy to find out what went into measuring the FTL neutrinos.
