Popular Standard View of stdQM
Philip Ball is a writer of popular science and in his latest contribution in Aeon he propagates yet another time the standard view that quantum mechanics does not make sense, as vividly witnessed and acknowledged by all great physicists:

On This Day in Math - September 30
Big whirls have little whirls,
That feed on their velocity;
And little whirls have lesser whirls,
And so on to viscosity.

In quantum physics, a bound state is a special quantum state of a particle subject to a potential such that the particle has a tendency to remain localised in one or more regions of space. The potential may be external or it may be the result of the presence of another particle; in the latter case, one ... |
