There's a history thread going on so why not a science thread. I know we have quite a few physics majors here but we can also talk about biology and other sciences. People can also ask questions in the hope that people in the know will answer them. I'll open some topics of discussion.
Quantum entanglement: Two particles are entangled when their total spin is constant, meaning they each have to take opposite values (this is like saying two coins have to be one heads, one tail, and never both). This means that if you observe the spin of one (e.g. spin up) you instantaneously know the spin of the other (spin down). However, each particle doesn't actually have a stable spin until it's observed, so the information for the second particle to be spin down is transfered instantaneously when the first one is measured. This isn't just eggheads on a blackboard, this is confirmed experimentally. What's up with that? Faster than light. Unfortunately you can't actually send any information that way.
Chemistry: Is it possible to have two quadruply bonded carbon atoms? Why not?
Biology: We learn that during mitosis, the nucleus dissolves and the chromasomes go to either side, then the cell cleaves down the middle and the nuclei reform. But what about the other organelles? Do they just randomly go to either side? Also, do mitochondria and chloroplasts have their own mitosis?
