@05017351 Oh yes, I meant the Pharaoh's Serpent wasn't exactly suitable for the classroom. I see how my previous comment was rather ambiguous!

I read about how a particle and its corresponding anti-particle have opposite spin. So if they are placed on opposite sites of the universe and neither have been observed, they are both in a superposition of states. Then one of them is observed and it affects the spin of the other particle (which...

@CommitToFocus Well it would need some oxygen to interact with, and I'd think that would need to be anti-oxygen (otherwise you'd get annihilation). In that case, in the end you'd end up with anti-water. I don't think it's possible to get partial anti-matter (or whatever you want to call it), but ...

@HKragh And taking it to the extreme here, what about gamma rays? I'd think that gamma ray photons (or whatever the correct term is) have enough energy to excite the electrons. Their energy would be absorbed and they wouldn't get through. Now I'm by no means very knowledgeable on the subject at a...

Please excuse my ignorance, but where can this recording be found?
I absolutely adore the cadence at the end of each melody line. It's so haunting, so reminiscent of so much.
