HOM is a two-photon interference effect where temporally overlapped identical photons coming perpendicular to a beam splitter must leave it in the same direction. How is momentum conserved in this process? Initially, the total momentum of the photons is only on the x-axis, but after the beam splitter, it has a y-axis component. Does some momentum pass to the beam splitter itself? | 0 |
Electric charges are of two types - positive and negative charges.electrons are negatively charged and protons are positively charged.

I found these two common English words (snarky and smarmy) that seem like forms of a literary device. However, unlike onamatopoeia, the comparison is not made with sound, but rather it is more from the "visual" images/memory that they evoke. What is this called in terms of "literary technique" (if not onamatopoeia)? "Synesthesia" perhaps? | 0 |

This is more a vocab question than anything else but what "type" of thing are injective, surjective, bijective. I fully understand what these words mean but I'm looking for a word to describe the type of properties these might be. Basically "odd and even" is to "parity" as "injective, surjective, bijective" is to what? Thank you all! | 0 |
Anyone have anything? I'm writing a "proof" for something and it came up. I'm stupid (as username suggests) and it would take way too long for me to solve it, and I wouldn't want to delete it since I want to just write QED in place of the proof for the solution | 0 |
I'm looking for a good noun to describe a character who can use Comakinesis, which is hair manipulation, but "Comakinesis-user" isn't good enough. Also, I can't find a word to describe hair manipulation in a magic user word ending in 'mancer' so I'm wondering if kinetic ability names have any kind of word form like that? | 0 |
Past Perfect can't be used on its own, can it? I mean, if there is a sentence without context, just a sentence on its own, and there is no clause with predicate in Past Simple in it.
