From spirals to spots to fractals, nature is full of interesting patterns. Many of these patterns even resemble geometric shapes. One of the most common? Hexagons. Why do we see this six-sided shape occur so many times in nature? This week we explore why hexagons are so common in the natural world, from honeycomb to bubbles to rocks, and what their mathematics, physics, and biology may have in common.

We've got two perfectly good hands attached to two perfectly good arms, so why do most people prefer to use one over the other for common tasks?

It's a long story…

How do you make a Grand Canyon?

Thanks to Mike from PBS Idea Channel and Jamin from PBS Game/Show for hanging out at the Grand Canyon with me!

https://www.youtube.com/user/pbsgameshow

Special thanks to Raymond Schillinger for great camera work!

I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't help but think, the Colorado River down at the bottom isn't that big. How did it cut a canyon so massive? How old is the Grand Canyon?

Here's its story

Waste not, want not… right? Poop, in all of its various forms throughout nature, shapes the world in ways you might not imagine. One creature’s waste is another’s fuel, and all over nature these leftovers help new life spring up. Here’s how whales, birds, worms, bats, and more help the world breathe clean, thanks to their poop.

Thanks to the following for their expert info:
