Seven Singular Points in Quantum Mechanics

Quantum mechanics was developed rapidly and abruptly. The former circumstance inevitably led to errors in the theory, while the latter forced researchers to advance without paying attention to the results obtained earlier. These two circumstances resulted in a number of errors. In particular, the probability of finding a 1s electron in the nucleus of the hydrogen atom differs from zero. However, annihilation never occurs. Consequently, the quantum-mechanical calculation of the spatial probability distribution is incorrect. The presented list of errors in quantum mechanics is not exhaustive. There are many other errors mentioned or not mentioned in the literature.
