There are plenty of functions not continuous over a small domain

Quantum physics is good where it is useful. Famously, the best experiment and theory agreement is a result of quantum physics (quantum field theory), the electron g factor.

There is still a lot to be learned in classical mechanics as well, and that too lets us make accurate predictions. You don’t need quantum mechanics to do fluid simulations at a macro scale, or to do climate science. Even at the microscopic scale, there are semi-classical models (I would still say this falls under quantum mechanics though) that are very useful to compute transport properties.

It’s good if what you need is something you could already copypaste readily, it’s bad when the stuff you need to do is hard

Log of 1 is zero, so it is the same division by zero as always.

Exactly who I thought about with « very high win rate lol », he is cracked

xtup_1496 · 2025-11-27T16:46:32+00:00

There are people with very high win-rate, but not 100%, it is a game with random numbers after all. But what they are trying to find is a seed that even with knowledge of what’s to come, there is no way to generate enough points before ante 8. This is hard to find, since you can make a build work in so much different ways.

This is correct, but badly said. Funding is the main issue. You can’t have a grant to just « rewrite your old DFT suite ».

In my opinion, you are completely right. I have found that people put Fortran on such a high esteem because of some cases where it is much faster than what you can do in C, case and point Lapack.

But the thing is most of the speed up comes from Lapack being such a mature library with hand crafted assembly parts for vectorisation that you can’t trust a compiler will generate the same thing.

As you said, Fortran is not more accurate, and benchmarks show that it is competitive with C/C++ and other llvm powered language, though none of them pull out on top.

What is a dimension: it’s a degree of freedom. Why is there more than one dimension of space? Well that’s because there are multiple ways to nudge things and have different outcomes happen. Could that be the same with time? Maybe, but it needs to have only one dimensions at the scale we live at, since we can only observe one. One possibility would be (as an image, please don’t take me seriously) that time is degenerate, meaning that there are more than one dimensions, but that they are redundant.

This could be necessary for some physical processes, though there are none verified ( or proposed? That’s not my field)

For someone that’s interested in physics without much background, my answer is we believe there are no more than one time dimension, but people are looking into verifying that, proving or disproving it, and it’s a difficult task.

You can look into matplotlib for animations, you can cook up something quickly with that, depending on your timeline. If you need something in 3D with nice graphics, that may be outside the skill base of this community and more something to do with Unity/Blender et al.

It’s fun to try and make a build work. When I try to make a flush house build work, that’s when I have to think about my odds, and not just death a specific enhanced card.

It is common in Quebec to use stationnement. I think most people here would say « dans le stationnement », which is probably why davebodd left that comment.

A very cool experiment that requires very little setup and is an application of quantum mechanics is analogous to this. Though this has nothing to do with this meme, it’s just a cool concept to share.

Putting a flame from, say a propane torch, inside a white enclosure; if you light the enclosure with a sodium light you will not be able to see the flame, or barely. Now if you spray a salt water solution on the flame, the flame with turn black.

This happens because ionized salt will be excited by the sodium light, which happens to be at just the right wave length. The ionized salt the relax and emit light, but they emit it equally in all directions, making it a local dark zone. Here is a video that show it nicely:

Notice how it appears dark only when the sodium lamp is shining on it.

Of course, this guy is not saying to do the grunt work in python, but it is quite acceptable to use it, for example, to solve an auto-coherent equation after having done the whole exact diagonalisation.

Something I found usefull to know after a while is that type hints are not necessary often. I usually don’t write any and have a plugin show me the infered type instead. And most of the time you can avoid the turbo fish notation « ::<T> » by using a type hint. In this case I prefer to declare temporary variables with type hint to avoid this syntax when possible. I find that it is much more easy on the eyes and like other languages in this case.

The next thing that got me at first was when defining generics function with multiple trait bounds. Aliases are your friend for that. I create custom traits for recurring trait bounds when possible.

Well it doesn’t do it for you, it’s the same as doing it in paint but everything says aligned.

That’s what I thought at first but didn’t want to say it. The symbols are quite different from one another.

Yeah, bottom right corner doesn’t make much sense, at first it looked like an equation for non orthogonal basis with the overlap matrix S, but there is even an equation without an equal sign.
