comment Why do lines in atomic spectra have thickness? (Bohr's Model)
Talking about Bohr model: I don't think it's explain it at all; in modern theories the thickness of absorption/emitting lines due to the uncertainty principle (the one about time-energy). And this was discovered far later than the Bohr model.

comment How would the representation of a circle in 4 dimensions?
Too short for answer: it's a hyper sphere! Or 3-sphere! Or glome! Also, the tags are mind-blowing.
