The spin vector is really only useful for calculations done on groups of particles. Also since a qubit is would only contain the spin-up or spin-down information, or a superposition of either, the 'direction' or 'axis' is irrelevant.
It means both 0 and 1 at the same time, with time-varying...
First of all, there is no end-all analogy for the quantum world. As soon as you understood the first watered down analogy I gave and found the flaw in it, you'd be right back at the doorstep looking for the next one. And so on, and so on, until sooner or later my analogy would be 'electrons...
Also, you might want to ask yourself, what makes the metals more 'metallic' than other elements? Compare those characteristics to non-metals, and you'll understand why the photoelectric effect can occur in non-metals at higher photon energies.
answer:
No. Most metals, especially the alkali metals, emit electrons from visible light. Non-metals emit electrons from higher energy photons, in the upper range of ultraviolet.
It's unclear how many dimensions there are. It's wrong to say with certainty there are infinite dimensions, and just as wrong to say with absolution there are only 3 spatial dimensions and 1 time dimension, or 10 dimensions, or 33 1/3 dimensions. There are many hypotheses on the matter. The...
Quantum mechanics is a mathematical framework for understanding physical phenomena that fail to be described sufficiently by classical physics: the work of Newton, Maxwell, and others. You might ask, 'Why can't we use classical methods at that point?' We're unable to sufficiently probe atoms...
