SmoothOperator@lemmy.worldto memes@lemmy.world•This is the hardest concept to understand in physics11·1 month agoWhat value does such an agreement have? Why is it a problem that there’s a plurality of equivalent understandings? Does that plurality add to or subtract from our understanding of reality?
You say the different interpretations give drastically different pictures of physical reality, but not in an empirical sense. But can we really talk of an empirically unavailable physical reality? If pilot waves, multiverses and wave function collapses all lead to the same empirical reality, does it make any difference to physical reality which one you think about?
SmoothOperator@lemmy.worldto memes@lemmy.world•This is the hardest concept to understand in physics2·1 month agoIt’s not so much that there’s no agreement, it’s that the different understandings all give the same empirical results, so there’s no way to decide on which understanding is “better”.
Settling the argument is a matter of taste, not science. At least for now.
SmoothOperator@lemmy.worldto memes@lemmy.world•This is the hardest concept to understand in physics1·1 month agoThat is a somewhat narrow definition of “why”, I’d say. But indeed, the transition from quantum mechanics to classical mechanics is unclear.
There are several interpretations of quantum mechanics, but they are empirically equivalent, so you can just pick your favourite and move on. That’s not necessarily a big mystery. The math works, as you say, and that’s the whole point of a physical theory.
There are also several interpretations of statistics. Does that mean we don’t understand “why” a dice rolls results with a certain frequency?
Note that superconductivity and the quantum Hall effect are both macroscopic quantum effects, so we do know what a macroscopic quantum system looks like.
SmoothOperator@lemmy.worldto memes@lemmy.world•This is the hardest concept to understand in physics64·1 month agoQuantum mechanics is extremely logical - we understand the math extremely well, and the math describes reality better than any other theory.
It is, however, not intuitive.
SmoothOperator@lemmy.worldto memes@lemmy.world•This is the hardest concept to understand in physics7·1 month agoDo you mean “why” as in “why did X cause Y” or as in “why are things the way they are”?
In the former case, quantum mechanics is our most precise theory for coupling causes and effects, predicting the outcome of experiments to an incredible degree.
In the latter case, do we really have a grasp of that for anything? Why is the gravitational constant the value that it is? Why is pi the ratio of a circle’s circumference and it’s diameter? Mostly we ultimately have to say that it is so because we can observe that it is so. For quantum mechanics it is the same.
Or do you mean “why” in some other way?
SmoothOperator@lemmy.worldto memes@lemmy.world•This is the hardest concept to understand in physics195·1 month agoI’d say we understand quantum mechanics better than most things.
We know more about the behaviour of an electron than we know about the oceans, the Earth, the sun, the weather, the stock market, the human body, prime numbers, and so on.

SmoothOperator@lemmy.worldto Patient Gamers@sh.itjust.works•What games did you get down with over the holiday weekend?3·1 month agoI actually like the lack of aim dot. A lot of the archery feels like it would be sort of trivial with an aim dot?
While it doesn’t make archery feel like real life, it does add to the feeling of starting out as a useless peasant.
We can define time at any arbitrary scale, Planck time is more like a limit to what we can measure.
Time doesn’t slow down on a massive object in its own reference frame. Think of the “one hour here is seven years on Earth” meme from Interstellar. To them, time is moving normally, but relative to Earth, it’s moving really slowly.
Time only passes differently relative to other reference frames (their planet and Earth, for example). Thus the theory of relativity!
If time did not pass, there would be nothing. Time passing is not cruel.
Time does not stop at Planck scale, what do you mean? In any system’s own reference frame time passes at 1 second per second, no matter the scale.
American: I have been to Jutland! I love Jutland.
Visits Midtjylland only 🤡
Especially offensive if you are a Jut like moi. You motherfuckers come here and think Midtjylland is Denmark, yet entirely ignore the rest of Jutland and especially Vestjylland where the oldest viking town is, where Dronning Dagmar died, where witches were burned, where old fisheries and new energy tech stand side by side, where beautiful beaches are littered with crazy nazi bunkers, where you can go north and surf or go south and see the flattest fucking place in the world, walking across the Vadehav to a literal island at low tide.
But no no. mIdTjYlLaNd is Denmark. The one place in Jutland where no one speaks Jutlandic, lol.
Plus free beer and food. Can’t beat that.

I’d still be very interested in the answer.
Ugh.
You can be a Swede and have a background or name from a different culture.
The gang he was leading was working in Sweden, i.e. a Swedish gang.
