Nathaniel Hawthorne's Thanksgiving
Humanness and strangeness are tied together, tragically perhaps, but inextricably. So it is for our strangeness that we ought, like Hawthorne, to give thanks most of all.
It takes Satan to bring out the true spirit of Thanksgiving. That's because it can be hard to give thanks unless you know why you are doing it. Plenitude is lovely. Abundance is a delight. ... When the devil is on your doorstep, however, thanks takes on a different timbre. The American most consistently preoccupied with thoughts of Satan was probably Nathaniel Hawthorne. Hawthorne never trusted in the good times. He saw the devil lurking in every moment of pleasure, waiting for the chance to pounce on the unsuspecting reveler when his guard was down. Hawthorne's story, "John Inglefield's Thanksgiving," is appropriately evil-obsessed. Utterly bleak, it is a difficult fit in the traditional American story of goods asked for, goods delivered, thanks given.
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.
