Quantum physics is becoming really popular on TV and other media, mainly b/c it has the potential to offer so much, but in reality provides so little. yea it sounds cool to talk about wormholes and quarks and leptons, but at the end of the day, what does this get us? I really think quantum physics got started by a bunch of geniuses who got bored and started breaking down matter to unnecessary levels.
Sure, I can tediously calculate all the electrons on my computer screen, or explain why benzene is a stable ring due to its orbitals. But at the end of the day, these don't really save or help anyone or anything.
Yes, I'm aware of the things physics has given us such as the atom bomb, etc. However, once we start talking about string theory and 5th, 6th, and 7th dimensions and so on...why does this matter, and what does this do?
If you look at the most beneficial achievements to human kind in the last 100 yrs..it's been mostly in biology, chemistry, and engineering (including computer engineering). I don't see how understanding the spin of a quark is ever going to advance human kind.
(P.S. we will never approach the speed of light)
