I guess. But I was looking at the actual libraries of computational QM programming repositories, and there is a lot of Monte Carlo for example but nothing explicitly Many Worlds. In Sean Carroll's advocacy of Many Worlds: https://www.preposterousuniverse.com/blog/2015/02/19/the-wrong-objections-to-the-many-worlds-interpretation-of-quantum-mechanics/ The people who object to MWI because of all those unobservable worlds <http://www.preposterousuniverse.com/blog/2012/06/04/does-this-ontological-commitment-make-me-look-fat/> aren’t *really* objecting to MWI at all; they just don’t like and/or understand quantum mechanics. Hilbert space is big, regardless of one’s personal feelings on the matter. So in Sean's presentation, if you object to Many Worlds then you don't like/understand quantum mechanics. [ But one could start instead with a (quantum) measure space: https://arxiv.org/abs/1002.0589 ] *When scientists proceed from the mathematics of any theory to an ontology of nature, they are being more of a religious guru than a scientific one.* @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
