Is there poop on the Moon?

Here to give us the down and dirty on space excreta (because let's face it, you were always curious) is Minute Physics' Henry Reich and Smarter Every Day's Destin. It's a match made in YouTube science-explainer heaven. With poop. And spacecraft-trajectory-altering pee. In spaaaace. » 12/14/12 7:00am 12/14/12 7:00am

The birth of quantum theory (deliciously, it involves cookies)

Some infinities are bigger than other infinities. Here's how we know…

Minute Physics' Henry Reich takes a break from physics to drop some maths knowledge. Using some basic tenets of set theory, Reich explains how we know that one infinity can be bigger than another. » 5/12/12 1:40pm 5/12/12 1:40pm

How Einstein Came Up With Special Relativity

Time dilation. Length contraction. The fact that time moves faster at your face than it does at your feet. These are all experimentally verified consequences of the Special Theory of Relativity, proposed in 1905 by Albert Einstein. But the theory also helped explain one of the most nagging questions of modern… » 3/19/12 8:20am 3/19/12 8:20am

How much milk would you have to vomit in order to levitate?

In X-Men: First Class, Banshee uses ultrasonic screaming like a jet pack to power his flight. In a recent video from special effects whiz Freddie Wong, a character named "Milk Man" gushes gallons of milk from his gullet to achieve a similar effect. » 2/13/12 8:45am 2/13/12 8:45am

How do we know for sure that we live in three dimensions?

Sure, our surroundings certainly appear to exist in three dimensions, but any good Cartesian will tell you that the appearance of a material object alone is insufficient evidence of its true nature. So how do we go about proving that we aren't, in fact, deluded inhabitants of Abott's two-dimensional Flatland, or… » 9/06/11 8:00am 9/06/11 8:00am
