That 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.

Quantum 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.

Do 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?

I'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.

Well, nothing increases it, but aren't there contexts where it is unchanged? Vacuum and single isolated particles don't increase entropy I suppose.

Local entropy, that is. At a global scale, life increases entropy.

Thank god for fridges

I 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.

I guess there is some cultural nuance - my impression is that for some people, sexual exclusivity is understood as an impossible virtue which it is important to appear to uphold, but where breaking it is kind of like sneaking a cigarette after having quit.

Which doesn't make them untrustworthy necessarily, they just have a different understanding of how big of a deal it is.

Interesting perspective. When you say any town, do you include places like Aarhus and Odense? If yes, what are the symptoms of the country dying there?

What small towns are you talking about specifically? There are definitely struggling places out there, in curious if we're thinking of the same places.

Also what's the issue with the prime minister drinking?

What was cool about Denmark 40 years ago?

Didn't all the mink farms close?

All together now: there are no paradoxes in quantum mechanics

The units don't really matter as long as you're okay with your number of kids coming out with units of square root time over length(?)

Sometimes you think you say the right thing, but you didn't, and you'll have to live with the consequences. This is a major part of the Witcher games, that your actions have possibly unforeseen consequences that you'll have to live with.

Accept that Triss has made her choice. If you don't want to be with Yen, then don't be with anyone, that's completely fine.
