Andy Matuschak@andy_matuschak·Apr 28, 2016Really interesting proof framework setup here. Set-theoretical operations on “experiment plots.”Quote TweetSean Carroll@seanmcarroll · Apr 28, 2016Provocative claim: "Single-world" interpretations of quantum theory cannot be self-consistent. http://arxiv.org/abs/1604.0742223
Steve Dekorte@stevedekorte·Apr 28, 2016@andy_matuschak note that this is no different that classical mechanics when you include the initial measurement error1
Andy Matuschak@andy_matuschakReplying to @stevedekorte@stevedekorte My understanding is that electron spin stochasticity is not explicable by classical initial measurement error. But IANAP. ;)10:45 PM · Apr 28, 2016·Tweetbot for Mac
