plz any high IQ anon, where does this equation derive from. I'm interested in a more general expression where charge is q instead of e.

The first equation is the very definition of the fine structure constant $\alpha$ while the second equation comes from maxwell's equations, $<br />c^2=1/\mu_0\epsilon_0$

thank you anon very helpful!. One more Q. Can the Bohr radius be measured directly through experiment without the knowledge of electron mass?

There's discrete lines of the hydrogen spectrum.

not really, for it doesn't exist. it only makes sense to talk about energy levels. these can be measured experimentally. the classical bohr radius is then inferred, but it doesn't mean a whole lot because the real nature of atoms aren't classical at all.

it's false. it can't be derived.
