It has been 50 years since I was taught or introduced to QM at the end of my EE degree. This article gives the best understandable history describing QM I can remember. It is written for someone informed in science but not an expert.

I found it refreshing as perhaps others here would also

Cosmology? Looks like quantum physics to me - moved.

I understand your thinking to move this from cosmology to this location. Cosmology includes QM explanations and my interest is keeping up with cosmology so I posted there. I thought it was useful to cosmological discourse. I stand corrected - thanks

Quantum theory is a bit younger, namely about 88 years old. It has been found (for the case of the harmonic oscillator) by Heisenberg in the summer of 1925, when he was recovering from an attack of hay fever on Helgoland.

What we celebrate this year is the Bohr-Sommerfeld model of the socalled "old quantum theory", which was immediately outdated with the advent of "modern quantum mechanics".
