Feynman rulez II
Avulsas
Question: somebody to tell me what the equivalent of (laser cooling in Atom Physics) in Solid State Physics would be?
Vejo isso ha tempos, e precisou o Gabor me avisar: "The Fourier transform is an entirely non-causal method of description."
Particulas passando por uma slit fininha como método de termalizacao, ou randomizacao da velocidade.
Why can't we in principle consider the magnetic field as generated by some kind of massless paired-particles (ie, particles glued and inseparable like quarks, which would explain the existance of north/south poles always together)(or almost always, keep reading), defined more or less as "created when we have electric charges in moooooovement")?
You know it's time you drop(p)ed a course when you're the only one in the classe who does seem deeply troubled when the lecturer says the words "non-abelian magnetic monopoles".
Why does one laser beam diverge, intrinsically? I think it should have to do somehow with the loss of coherence, but the post-doc I work with thinks it's bullshit. But wasn't able to give me a satisfactory answer either.
Why does the Action S in QED bekommt some kind of imaginary part when we consider pure magnetic interactions (genre, spins), and what does this imaginary part represent? (That it gets some kind of imaginary part, my imaginary friend Richard told me in one of his books)
Some "on how to use information sheet" on quarternions. And the meaning of the two extra axis (when you're fairly convinced that i can be useful, and when you're just getting used to imaginary times and stuff, some guy just introduces two more axis, and you're lost again).
