A Most Delightful Map

Friday, September 13, 2013

What I'm going to say sounds ridiculous, but once upon a time it wasn't ridiculous at all. You could wake up one morning in North America and decide to walk to Morocco, have breakfast, and a few hours later, there you are — in Africa. No sweat. Or wander from Australia into Bangladesh. Not a problem. Let me show you how.

A New Kind Of 'More'

Tuesday, September 10, 2013

If you care about the environment, if you're a good person, you try (in many little ways) to cut back, do with less, live more simply. But when nobody's watching, when you're feeling naughty, you dream of "More-ing," which is both totally irresponsible and crazy fun.

There was a spruce tree in Stanley's garden, and when September rolled around, a family of garden snakes used it to sunbathe.

Drone It To Me, Baby

Friday, August 30, 2013

Drones are for spying, right? Right. But if Jasper van Loenen's idea works, drones will also become private moving vans. Crows won't like this. Trees won't like this. I'm not sure I like this. But you've got to see Jasper's instant-drone deliver a bicycle wheel across campus ...

Friday, August 23, 2013

What happens if you take a beach creature, a little worm, or an oyster, and move it to an aquarium far from the sea? Will it still imagine tides? Yes, it will.

Wednesday, August 14, 2013

Think about the E.T. in "E.T." It was fetching, adorable and two and a half feet tall. Now think about the E.T.s we hope to find on Mars, Europa or Titan.
