I Proving the Schrodinger Equation

Click For Summary
Scientists proved the accuracy of Schrodinger's equation in the 1920s primarily through its successful predictions of atomic spectra, particularly for hydrogen, rather than direct measurements of electrons. The equation's validity is supported by inferring energy levels from spectral lines, which reflect the behavior of subatomic particles. Monitoring an electron's momentum and position is challenging due to their small size, requiring advanced techniques and indirect measurements. The accuracy of experiments aligns with the probabilistic nature of the equation, where repeated measurements improve the reliability of the probability outcomes. Overall, the Schrodinger equation remains a cornerstone of quantum mechanics due to its predictive power and foundational role in understanding atomic behavior.

TL;DR
How were scientists able to do experiments to prove that the Schrodinger equation was correct?
How did scientists prove the accuracy of Schrodinger's equation to describe the behaviour of subatomic particles, especially in the 1920s? How do you monitor an electron's momentum and position when they are so small? Also, if the Schrodinger equation just describes probabilities, is the accuracy of the experimenting based on doing the same measurements over and over to make sure the probabilities are correct (in the same way to check the heads/tails probability of a coin, the more measurements the better, as it will tend towards 50%)?

You probably need to read the history of QM to clarify the exact sequence of events. In modern QM, the Schrodinger equation can be derived from some expected properties of the time evolution operator: see, for example, Modern Quantum Mechanics by J..J. Sakurai.

The acid test is not direct measurements of an electron, but the prediction of the atomic spectra for hydrogen etc. In this case, even the different energy levels themselves are not measured directly but inferred from the atom's spectrum (i.e. the measurement is of the wavelength (or frequency) of the emission and absorption spectrum).

We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...
