A Quick Bit of 'fizicks P4

7. Many Worlds Interpretation (Hugh Everett III)

Ignored for years after its appearance in 1957, the many worlds interpretation has gained in popularity in recent decades. Sometimes called the “many universes” interpretation, it postulates that every time a measurement is made, all the possible outcomes actually occur in different branches of reality, creating a multitude of parallel universes. Actually, Everett thought of it as more like the observer splitting into different clones who follow the different possible measurement outcomes. In any case, it’s weird.

"For the record: Quantum mechanics does not deny the existence of objective reality. Nor does it imply that mere thoughts can change external events. Effects still require causes, so if you want to change the universe, you need to act on it." Krauss

"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

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

Part 3:

"It's strange that words are so inadequate. Yet, like the asthmatic struggling for breath, so the lover must struggle for words."

T. S. Eliot

"If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet" - Niels Bohr.

"The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa."* Werner Heisenberg. SAY MY NAME! 

preamble...-Brady: "Hello 'fizicks, how are you? I am told Quantum Mechanics has multiple interpretations? Can you explain to me again, what these interpretations are, and what it all could mean?" "Thanks 'fizicks...perhaps for ease can you refresh me by listing them one through to descending order? 
-Fizicks "Sure"
Brady "-fuck- heck yeah...

9. Bohmian Mechanics (David Bohm)

I don’t really like this one very much, but it has many fans and deserves to be mentioned. Developed in the 1950s by Bohm, based on earlier views from Louis de Broglie, Bohmian mechanics describes particles flying around as guided by “pilot waves.” Those waves tell particles where to go. Supposedly this approach turns physics back to determinism, avoiding the probabilities that Einstein condemned by saying “God does not play dice.” Since experiments have ruled out “hidden variables” for enforcing determinism, Bohmian mechanics requires a form of action at a distance (or “nonlocality”). Einstein didn’t like that either. It’s also hard to see how Bohmian mechanics would predict any experimental difference from the predictions of standard quantum mechanics. Shortly before he died, Einstein said he wasn't impressed with the Bohmian interpretation. “That way seems too cheap to me,” Einstein wrote in a letter to physicist Max Born.

Number 9 will be in part 3 as soon as ready...
