Why e-Books Won't Replace Books
Slate recalls Marshal McLuhan's distinction between hot and cool media to say that ink on paper is perceived differently than type on screen. One, therefore, cannot completely replace the other.
Slate recalls Marshal McLuhan's distinction between hot and cool media to say that ink on paper is perceived differently than type on screen. One, therefore, cannot completely replace the other. "I discovered, to my chagrin, that drafting first on computer tended to come out better than by hand," says Jan Swafford who takes a writer's perspective on the competition between print and electronic media. "Computer drafts were cleaner and crisper. But, after that, I also discovered, paper rules. The final polish, the nuances, the pithy phrases, the tightening of clarity and logic—those mostly come from revising on paper."
- Some are concerned about the proliferation of space debris in Earth's orbit.
Protected animals are feared to be headed for the black market.
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.
