@lain@velartrill eh, maybe in social sciences that happens more often, but "true" isn't really the way anything is being taught or talked about in "hard" stuff now, think. still go through the whole newton -> tongue-guy・maxwell -> schroedinger progression stuff for every student, and each step gets presented as "these are all models that can make some useful predictions but diverge from what we've measured in other places, and the working assumption is that we're still mostly or completely wrong and there's so much that we just don't know and, really, isn't that kind of beautiful?"
@lain to some extent that's true but mostly not because if it was none of these fancy whizz-bang doodads we use to scam and harass each other from afar would work
@lain@velartrill eh, that side of things i see mostly as another offshoot of mathematics, playing head games and leaving application-finding to others. and dipping more into the "wild theory" side of things as you get older seems a natural phenomenon too, for many (see gödel・einstein・penrose, or could even bring in newton)maybe there are some physicists pushing it as hard "truth", but personally never met any. the wasting your time・wasting your mind argument is a bit separate from that, but to me feels just "people will do what they enjoy"; not convinced by a must-be-utilitarian position personally. and anyways don't know what things might be "useful" in the future; whole string theory path has definitely stress-tested・expanded on・brought more people into some really neat maths that might be useful elsewhere
@shmibs@velartrill i can't agree at all. presumably 'hard' physics has been chasin string theory for 40 decades now (without any experimental connection to reality) because it's 'too beautiful not to be true'. read the stuff Witten says about it. it's not rational and it didn't get us anywhere. Now that it's clear that something like M-Theory (which is a theory in the exact sense that creationists think (and got bashed for by 2010 online atheists)) won't get us anywhere beyond a 'landscape', leading physicist suddenly find that we all probably live in a multiverse (which can't explain anything so it's okay that string theory can't, either). Or the stuff that tegmark talks about, which is also purely philosophical.
@lain@shmibs@velartrill m theory is the closest we will have to a theory of everything for a long while. I wonder if/when supersymmetry will be proven.
