The $200 Andriod OS Tablet

Brett Arends tells how he transformed his Barnes & Noble Nook e-reader into a functioning tablet device with an Android OS using free and legal software from the Internet.

While people line up to get their hands on the next generation iPad for $500, an alternative is available. Brett Arends explains how to transform an e-reader into an Android OS tablet: "I bought a Barnes & Noble Nook Color tablet. And then I downloaded a very simple, perfectly legal software fix from the Internet that turned it into a fully functioning tablet running on Google's Android platform. The fix, known as a 'rooting,' unlocks Barnes & Noble's proprietary overlay. The instructions came via Ars Technica, a reputable site devoted to technology, and were pretty easy to follow. I wasn't really expecting it to work. I tried it as an experiment. But the results were remarkable."

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
