Quantum Escapism 2020-08-22T04:00:00Z They also verified another strange prediction of quantum mechanics: the lower the energy, or slower the movement, of a tunneling particle, the less time it spends in the barrier. Quantum Tunneling Is Not Instantaneous, Physicists Show 2020-07-22T04:00:00Z “If you think quantum mechanics is unhealthy, and it needs replacing, then this is useful because it tells you new constraints,” Vaidman says.

The Rebel Physicist on the Hunt for a Better Story Than Quantum Mechanics 2020-06-25T04:00:00Z The best example is quantum mechanics, whose fundamental principles deviated qualitatively from classical physics but were forced upon us through experiments. Beware of 'Theories of Everything' 2020-06-09T04:00:00Z It's clear that we’ve done this with Newtonian mechanics, with electromagnetism, with relativity, quantum mechanics, cosmology, and more. A Failure of Imagination 2020-05-23T04:00:00Z Albert Einstein admitted in his final essay, ‘Autobiographical sketch’, that fellow physicists opposed his quest to unify the general theory of relativity with quantum mechanics.
