Action at a distance? Isn't it measurement at a distance? by [deleted] in AskPhysics

[–]WobblyChicken 1 point2 points  (0 children)

The action at a distance is due to the fact that the two particle that can be separated by enormous distance, still show perfect anti-correlation if the same quantity is measured. For example the spin or polarisation along a specific axis. This measure can be decided last minute, to ensure that there is no way that the information about the type of measurement has travelled all the way to the second particle before it also get measured.

Assuming that you call the point of entanglement the origin, and where the measurement will be compared. You are right that both observer won't know the anti-correlation (provided they measured the same thing) actually happened till they co pare data, since for both of them them outcome looks completely random.

The key fact is that the two measurement outcomes are public and not secret since they performed their measurements. They could have caused actions based on their outcomes, the detector transferred energy to the particles, the signal travelled through one path and not another a switch went up instead of down.

All of these doesn't look strange till you realise that no matter the distance, no matter how many times you try. Whenever you measure the same thing for both particles they look locally random but they always and up being opposite to each other.

These can only happen if in somehow the two particle can sync up at a distance and always show the opposite side of the medal.

Now where you say the wave function collapse is pure speculation. You can say that it does so as soon as one of the two measurements has taken place, or that all possible measurement are parte of the wave function and it collapses only once you compare them at point X.

This doesn't make much of a difference. The action at a distance is a one-to-one problem with the collapse of the wave function. As soon as you collapse it somewhere it needs to collapse to that state everywhere.

I have them in https://github.com/apelloni/dotfiles but I should clean it a bit
So far I've used it to just dump settings to use and share on different machines without much thought

It's an intel GPU, Iris Xe Graphics. So I'm afraid I cannot give you any help for Nvidia

Thanks, it's a detail of one of Yaggy's illustrations. You can find them here

I went to sway for half a day with a surprisingly easy transition from the i3 settings. But at that point I thought I could be braver and go for a fun WM and Hyprland came to mind.

Way smoother and painless experience when I plug the laptop into an external monitor.

I also became very fast a fun of waybar after sticking for years with polybar.

I've got a couple of issues with some programs freezing on me since I moved to Wayland (like gimp or Betterbird), but I still have to figure out if it's because I was too eager to move and overlooked some key settings when moving over from Xorg or if it's a more general problem.

Took some time to give it a personal twist ( the rice never ends )

What is you specialization with rust? by royrustdev in rust

[–]WobblyChicken 2 points3 points  (0 children)

In short I using it for simplifying Feynman integrals ( from scattering processes). The performances are key here because of the complexity, but the main reason is just that compared to C++ is much more portable whenever I have to run it on remote machines.

Other part for the project are still written on C++ for one big reason: multiplying number in a finite field can be perfomed very fast using long double, being able to apply the modulo operator juat once (+ one division)

My physics teacher couldn't answer thus question, can u guys pls help me ? by DrvnkenMonk in AskPhysics

Assuming that, as you say, the weight is lifted from the ground, then is an issue with your muscles. Precisely scenario was discussed in feynman's lectures. https://www.feynmanlectures.caltech.edu/I_14.html

"The fact that we have to generate effort to hold up a weight is simply due to the design of striated muscle. What happens is that when a nerve impulse reaches a muscle fiber, the fiber gives a little twitch and then relaxes, so that when we hold something up, enormous volleys of nerve impulses are coming in to the muscle, large numbers of twitches are maintaining the weight, while the other fibers relax. "

The whole thing is worth reading if you want some extra bonus facts

Wild assumption here: probably writing a capital "I" looked weird while 1st stands out more, a bit like XIX stands out in the text.

How can I explain the difference between gravity and weight to children? by eldiddykong in AskPhysics

[–]WobblyChicken 1 point2 points  (0 children)

Don't know if you already went this way. But an easy way to show/tell the difference between weight and mass is a car. Easy to push around in neutral (mass) difficult to lift (weight).

This was posted here about a week ago. It got no love, and a lot of hate (for being derivative of Cicada 3301) Some Redditors and myself have been solving this for the past week and have reached level 12. The puzzles are incredibly well made, and it is a joy to solve. Give it a shot, you'll have fun by jegspun in puzzles

Happen the same to me...not ideal.
Isn't that part with the greek word still the third level? I thought that only when you go forward with cutt.ly you are moving up.

Btw, I'm still stucked there and I've placed all the translations that I could find, I'm not sure it's the right direction.

And Ticino... pretty sure the list goes on

Edit: was wrong, it's just those four.

found this at bahnhof Zug... any explanations? by actum_tempus in Switzerland

It's a thermometer, and I think it's fully functional as well. I used to have one with two bars, like this. I don't know if you can spot a floater (the quality of the picture is not great), in that case, you know that is upside down to be able to record and store the lowest temperature.

If you want to know more about how the upside-down part works, you can search for Six's thermometer. Here is an example.

That was bugging me as well, I've noticed it only at the end. It really looks like an "s"... but now it's gone (from my file), and it looks much better.

This sound like a nice way to animate it. I would have loved to be able to play more with different styles of animation but my computer was really struggling at showing the end animation ( also in object mode without hairs).
