... “Measurement” (which is NOT precisely defined in QM!) changes the wave. It “collapses” it to a wave appropriate to the measured value. The best possible measurement of energy puts a system in an energy “eigenstate”, which we also call a “stationary state” When in a stationary state, the probability ...

Towards a Quantum Mechanical Interpretation of Homeopathy
... pages of this distinguished journal, there has been a lively discussion of the effect of extreme time-dilution in the case of homeopathic exercise (4, 7). It is proposed that exercise in the order of minutes down to nanoseconds per month shows distinct health benefits. This paper shows that quantum ...
