We tend to think of science as finding equations, like E=MC2, that are simple and elegant. But maybe some theories are complicated, and we can only find the simple ones.

If you gave kids peas that didn't look like peas and said they were a space shuttle, they're much more apt to eat them because it's now playtime.

3D printing is already shaking our age-old notions of what can and can't be made.

A hexagonal piece of cheese is a lot better than a square piece of cheese.

If you're talking 100 years, there's no doubt in my mind that all jobs will be gone, including creative ones. And 100 years is not far in the future - some of our children will be alive in 100 years.

But they aren't here. Meanwhile, we have illegal immigrants doing all the work, but we don't have any robots.

Similar to computer technology in the '60s, 3-D printing is a universal technology that has the potential to revolutionize our life by enabling individuals to design and manufacture things.
