"To see a world in a grain of sand, and heaven in a wild flower, Hold infinity in the palms of your hand, and eternity in an hour."

William Blake


"Science is imagination in a straight jacket" Richard Feynman



9. Stochastic evolution interpretation (many versions)

This one perhaps isn't strictly an interpretation of quantum mechanics itself, because it changes the math. In ordinary quantum mechanics, the wave function (or state vector) “evolves,” changing over time in a perfectly predictable way. In other words, the odds of different results can change, and you can predict exactly how they will change, up until the time a measurement is made. But several physicists have suggested over the years that the evolution itself can change in a random (or stochastic) way causing it to collapse all by itself. Presumably this collapse process would occur very rapidly for large (macroscopic) objects and slowly for subatomic particles. Nobel laureate Steven Weinberg recently examined this approach in a paper available at arXiv.org.

Feynman once said, 'Science is imagination in a straitjacket.' It is ironic that in the case of quantum mechanics, the people without the straitjackets are generally the nuts." L. Krauss


(Warning: Summaries below do not reflect all the subtleties of the various interpretations, which have often been modified over time by supporters or even the original authors. I’m just conveying some of the flavor. As cosmologist Max Tegmark writes in his new book Our Mathematical Universe: “There isn’t even consensus on which ones should be called interpretations.” (Note to advocates of various views: do not be concerned about the order in which these are listed. There is some quantum randomness here lol)") - 'fizicks
