comment Did relativity make Newtonian mechanics obsolete?
Actually, there's a big important difference between Newton and Einstein. Newton believed in the existence of an absolute frame of reference in the universe, completely incompatible with a relativity principle that stipulates that all frames are equivalent. Newton had long discussions with Leibniz about this. In this sense, Leibniz ideas were close to Einstein's, with the modifications you suggest, but Newton's were the complete opposite, completely incompatible. Wikipedia's somewhat incomplete article on the subject: en.wikipedia.org/wiki/Absolute_time_and_space

comment Complex conjugate of momentum operator
$\hat{A}^*$ is coherent with the notation used in the question, which uses $\hat{p}^*$ as the hermitian conjugate of the impulsion operator. Althought not standard among physicist, it's the one chosen to formulate the question.

comment Complex conjugate of momentum operator
Working on the space of infinitely differentiable functions, the distribution of the hermitian conjugation is correct in the way depicted in the question. The only problem would arrise when conjugating the multiplication of operators, in which case the only correction needed is to inverse the order of the operators in the product, like $(\hat{A}\hat{B})^*=\hat{B}^*\hat{A}^*$

comment Magnetic field exclusion and retention in superconductors
Yes, I see why it gets trapped, but my question is why doesn't the exact same thing happen when the magnetic field is applied after the phase transition from normal to superconductor qnd then turned off?
