S2011 E7 • What is the Sound of Hydrogen?

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!

S2011 E8 • What is Quantum Tunneling?

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

Première diffusion : 14 août 2011

S2011 E9 • Adding Past Infinity (WARNING: Math Ahead)

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.

S2011 E10 • Tutorial: creating the sound of hydrogen

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!

S2011 E12 • Distance and Special Relativity: How far away is tomorrow?

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

Première diffusion : 4 septembre 2011

S2011 E13 • What is fire?

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.

S2011 E14 • Taming Infinity

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

Première diffusion : 23 octobre 2011

S2011 E19 • How to break the speed of light

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

Première diffusion : 30 octobre 2011

S2011 E20 • GPS, relativity, and nuclear detection

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

Première diffusion : 7 novembre 2011

S2011 E21 • The Arrow of Time feat. Sean Carroll

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.
