Was the notion of observable really necessary before quantum physics?

I'm a mathematician who's been struggling with the search of connections between physics theories and $C^*$-algebras. The most known connection I found was that the observables in quantum mechanics...

Are electron spin axis and magnetic moment axis fully aligned?

It is known that the electrons behave in magn. moment detectors experiments at 45 degrees non classically but quantum mechanically where the amount of spin up and spin down electrons...

Rapid-fire projectile motion such that all particles land at the same time

A short-barrelled machine gun stands on horizontal ground. The gun fires bullets,from ground level, at speed $ u $ continuously for a period of one second, but does...

Is this a correct way of finding magnetic field of a magnet created with Wasilewski's method?

$quad$ Wasilewski's method (Or the method that could be seen in Dr Stone episode 9) consists of piece of iron being struck by a lightning, which then magnetises it....

Is the digital representation of acoustic waves directly proportional to displacement(or pressure)?

In most audio editing software(like audacity) waveform can be viewed. Zoomed in these look like actual waveforms. Out of curiosity I downloaded some frequency sweep test files(which are intended to...

Conservation of momentum and translation symmetry

Physics laws should not be changed under translations, so the Hamiltonian must commute with the generator of translations, which is the momentum operator, that is $[H,P]=0$. However we know...

Is wavelength twice the amplitude in longitudinal waves?

I knw it sounds dumb, but here is my problem. I can clearly imagine why amplitude has nothing to do with wavelength in a transversal wave, as they are measured...
