When eating pizza, New Yorkers will recommend that you fold the slice in half longways to reduce mess. Now find out about the math and physics working behind the scenes of that tradition in TED Ed’s Pizza physics (New York-style) by Colm Kelleher, animation by Joel Trussell.

We wish that all of our foods explained related math and physics ideas to us… and more about shapes, too.

Master juggler Michael Moschen weaves rhythm, physics, and hand-eye coordination into this wonderful performance called The Triangle. 

There are a few more jugglers juggling in the archives.

Thanks, Shonali.

To celebrate Commander Chris Hadfield’s return to earth today, Monday, May 13, Scientific American has collected the Top 10 Commander Hadfield Videos from the International Space Station. Excellent watching all around.

Above: the most popular video on their list, Wringing out Water on the ISS - For Science. And a just-released bonus vid below, the Commander’s version of David Bowie’s 1969 Space Oddity:

It’s the first music video made in space.

Even if you’ve seen This Too Shall Pass, the 2010 instant classic from inventive band Ok Go, it’s a great video to watch again (and again).

With the help of SyynLabs, director James Frost, and the support of almost 60 people (from core builders to people helping to reset machines) OK Go put together a massive Rube Goldberg setup that includes bowling balls, barrels, sledgehammers, umbrellas, legos, a car, an unfortunate piano, and paint cannons.

This Too Shall Pass also has an “official” video:

And of course, it’s fun to watch these related OK Go viral hits again, too: their breakout single Here It Goes Again, and Three Primary Colors for Sesame Street.

More Rube Goldberg machines are in the archives.

Toast slices as dominoes? Yes, please. This domino-driven Rube Goldberg-esque video may not be all in one shot — and maybe some of it is helped with some digital post-production? I’m looking at you, parachutes — but the use of a fan with feathers, a flip-book style animation, an underwater shot, and a few Cobra Weave Exploding Stick Bombs all throughout a huge house sets this one apart.

A-Trak & Tommy Trash’s Tuna Melt, directed by Ryan Staake. There’s also a behind the scenes vid.

More Rube Goldberg and chain reaction videos await in the archives.
