Why are electrons taken implicitly to be the elementary charge? It would save a lot of fractions in particle physics problems.
Normally, we use the letter $f$ to stand for frequency in equations. $$T = 1/f$$ $$v = \lambda f$$ $$Φ +E_k = h f$$ So I'm curious as why the letter $ν$ (nu) is used to represent frequency in the ...
For some reason everyone labels electrons using a minus sign and protons using a positive sign, even though the opposite seems more intuitive: Who started the convention that electrons should be ...
The partition function plays a central role in statistical mechanics. But why is it called ''partition function''?
