What drives Rudy Giuliani?

Matt Bai: I suspect like most people he’s running because he’s always wanted to be president and thinks he’s . . . thinks he’s smart enough, good enough, and charismatic enough to be president; has that . . . has that good a sense of himself. And . . . and you know I think he’s running on a very simple premise, which is you don’t have to think I’m a nice guy. I’m not looking to babysit your kids. You don’t have to agree with everything I agree with. We disagree about some things in there. And I’m gonna do my best not to make a mess in those issues that you care about, like abortion or whatever else. But none of that matters. The only social issue that matters is we are now under attack by a civilization. We are now under . . . under the siege of radical Islam from around the world; and that, you know, I’m the guy who can keep you safe. I’ve proven that I’m the guy who can . . . who can direct troops and keep people safe. I did it in New York City and I’ll do it in the country. I mean he’s running as an anti-terror president. That’s kind of all there is. And everything else he’s running . . . every other issue is just there to mitigate potential opposition so he can focus people on the one thing he cares most about.

He is our anti-terror president.

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.

Project 100,000: The Vietnam War's cruel and deadly experiment

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.

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.
