Peter Pham’s Biggest Spending Mistake

Question: What has been your biggest spending mistake?

Peter Pham: College. You know, I was in college and I was one of those first credit card you get not really knowing a lot and ran up my credit card debt quite a bit. Essentially, paid for my college experience, but regretfully not understanding interest rates. I mean, compound interest, penalties, and minimum payments don't last forever. That was the big, big mistake and I hope to educate as many people as possible to not get in the same trap. Coming out of that, I've learned a lot around how credit cards work and how the credit card industry actually is a profitable industry. For me, now, it's how do I get the most out of my mileage? I travel a lot; I use my credit card a lot and so I'm kind of getting back by making sure I have the best credit card in my wallet and being sure I'm earning the most amount of points.

How to make a black hole

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

Videos
  • 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.
