While studying the spin-orbit effect in quantum mechanics, the relativistic effect on both magnetic and electric fields due to a change of reference frames was briefly mentioned. Isn't it wonderful that two static electrons interact via the electrostatic field E only, but when observed from a moving frame suddenly a magnetic field B appears! The electrons do not "care" about whom is observing them, they just "feel" a force and that's it, end of story.
That reminded me of Feynman's famous quote:
"If our small minds, for some convenience, divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on — remember that Nature does not know it!"
Isso é uma visão materialista de consciência. Não que eu discorde, mas é.
