The first key to thinking about 3-D printers is this: Do not think printer. Think magic box that creates any object you can imagine.

In the box, razor-thin layers of powdered material (acrylic, nylon, silver, whatever) pile one on top of the other, and then, voila — you've got a shoe, or a cup, or a ring, or an iPhone case.

It's miraculous to see. Press a button, make anything you want. But just how important is 3-D printing? Unlike earlier big-deal technologies (like, say, the tractor) 3-D printing won't really replace what came before.

Others are expressionless and indistinct. The project is intended to help the seniors remember what they look like.

This is the Gangseo District Center for Dementia. Since 2006, Seoul has opened a dementia center in each of the city's 25 urban districts.

Negative Temperatures That Are Hotter Than The Sun

Scientists have cooled potassium gas to one billionth of a degree below absolute zero. But in the quantum world, that's actually hotter than the Sun. It's hotter, even, than infinity degrees Kelvin. Vladan Vuletić, a quantum physicist at MIT, talks about this 'Bizarro World' temperature.
