Micah Sifry Hopes Obama Can Meet High Expectations
Micah L. Sifry is co-founder and editor of the Personal Democracy Forum, a website and annual conference that covers the ways technology is changing politics, and TechPresident.com, an award-winning group blog on how American politicians are using the web and how the web is using them. In addition to organizing the annual Personal Democracy Forum conference with his partner Andrew Rasiej, he consults on how political organizations, campaigns, non-profits and media entities can adapt to and thrive in a networked world. In that capacity, he has been a senior technology adviser to the Sunlight Foundation since its founding in 2006.
Sifry is also the co-editor of Rebooting America, an anthology of writing on how the Internet and new technology can be used to reinvent American democracy (available online for free download at rebooting.personaldemocracy.com), co-author of Is That a Politician in Your Pocket? Washington on $2 Million a Day, author of Spoiling for a Fight: Third-Party Politics in America, and co-editor of The Iraq War Reader and The Gulf War Reader. His personal blog is at http://www.personaldemocracy.com/blog/micah_l_sifry.

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.
Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?
- During the Vietnam War, Robert McNamara began a program called Project 100,000.
- The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
- Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
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.
