I just like the feeling like i'm under the influence of acid, imagining quantum particles and nerdy stuff while doing the most trivial things, such as shopping groceries.
We are about to enter the age of the atomic laser. Quantum mechanics on a macroscopic scale. By creating coherent bose-einstein condensates we will soon be putting the technology on star trek to shame.
Again, you're going to have to google it. I cant do links etc on my phone
I like thinking about these things when I don't feel like being paralyzed in thought and not doing any work at all. Especially not of the multivariable calculus variety.
