The Flipped Future
Elizabeth Stark has taught at Stanford and Yale about technology and the Internet, starting the Ideas for a Better Internet Program at Stanford to engage students in working on projects to better the future of the net. Stark has spent years working on open Internet issues, and was one of the key organizers in the anti-SOPA movement that engaged 18 million people worldwide. She is a cofounder of the Open Video Alliance, which seeks to promote innovation and free expression in online video, and produced related conferences that involved nearly 9000 people in person and across the web. She serves as a mentor with the Thiel Fellowship, has collaborated with companies such as Google and Mozilla, and is an Entrepreneur-in-Residence at Stanford's StartX. Stark is a graduate of Harvard Law School and an affiliate of Harvard’s Berkman Center for Internet & Society. She has lived and worked in Berlin, Singapore, Paris, and Rio de Janeiro, and speaks French, German, and Portuguese.
Elizabeth Stark describes how Internet activism stopped legislation such as SOPA, which she saw as a threat to online freedom.
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.
Protected animals are feared to be headed for the black market.
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.
- 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.
