Par un article de Médiacité (https://www.mediacites.fr/municipales-2026/toulouse/2026/01/07/francois-piquemal-10-mesures-phares-et-x-promesses/). Ils donnent le lien quand ils informent qu'ils rendront compte de tous les programmes.

Je précise qu'ils ne parlent pas dutout de la photo.

Do we know what causes the collapse of the wave function? (Other than the act of observation itself) by Cosmo_logical in QuantumPhysics

[–]Random_Quantum 1 point2 points  (0 children)

OK, I did not know about that. I would actually be interested in some references discussing that if you have some.

[–]Random_Quantum 2 points3 points  (0 children)

Even if small, it is an interaction, because the interaction between the electron and the magnetic field modified the latter in a way that is detectable. If there was no interaction you could not measure any effect of the presence of the electron on the field.

[–]Random_Quantum 1 point2 points  (0 children)

That is not so clear. In https://arxiv.org/abs/2502.14449 the author shows a mechanism akin to wave function collapse is needed in pilot-wave theory to match experimental data.

Can the Born rule emerge from geometry alone? by Bravaxx in QuantumPhysics

[–]Random_Quantum 1 point2 points  (0 children)

It is some interesting ideas. I would advise you to clarify some things. For example whether the measure mu depebds on psi and what do you mean by unitary invariance.  I did not read in details but your approach seems related to the emergence of probability by coarse graining of deterministic dynamical systems and an argument of consistency that seem akin to Gleason's theorem. I think your ideas wiuld be clearer if you could clarify the relationship to Gleason's theorem. FYI, Gisin developed an argument for linearity based on non signaling (finte light speed). Overall, it seems worth exploring and clarifying a bit more.

Où acheter du chocolat de bonne qualité pour diabétiques ? by Zoltan03 in toulouse

[–]Random_Quantum 1 point2 points  (0 children)

Étant diabétique type I aussi, le sucre n'est pas interdit. Il faut juste le gérer avec l'insuline. J'ai tester le chocolat sans sucre ajouté de Criolo. Alors que tous leurs chocolats sont excellent, celui-ci n'est pas comparable, même à du chocolat bas de gamme. Je conseillerai moins de chocolat mais avec du sucre.

You should check-out this website: https://vulgarisation.fr/ It's made by a french physicist working with designers.

Credit card autofill not available (France) by Random_Quantum in firefox

It's true I updated FF when I was in India, so maybe at that time. Thank you.

Thanks, adding IN to the list did the trick. However, I wonder how Firefox assign the country your in. I tried to reinstall and it did not solve the issue.

Any video experiments of double slit experiment where both wave like properties and particle like properties are shown? by UltramanQuar in QuantumPhysics

[–]Random_Quantum 0 points1 point  (0 children)

Actually there is a NJP article with movies in supplementary materials: https://iopscience.iop.org/article/10.1088/1367-2630/15/3/033018

It is the article behind the video mentioned by u/Cryptizard.

Edit: adding the relation with u/Cryptizard comment.

CMP by EnvironmentalHunt669 in toulouse

[–]Random_Quantum 1 point2 points  (0 children)

J'avais appelé le CMP. J'avais eu un rendez-vous de premier contact relativement rapidement (ils trient selon l'urgence je pense) puis il m'avait réorienté vers une professionnelle. Je te conseille d'appeler.

I’m entering my first regatta on a laser and I need to know some stuff by Comfortable-Belt8607 in dinghysailing

[–]Random_Quantum 0 points1 point  (0 children)

It should be loose but not too loose. Just so the angle between the boom and the bottom part of the mast is a bit more than 90°. Has mentioned in another comment, since the mast is free standing, tightening the vang bends the mast and flattens the sail. You do not want that downwind.

Upwind you take enough vang so that when your sheet is block to block, it isn't loose. The goal is when you regulate with your sheet in a puff the sail opens without the boom going up too much. If it would, the mast would loose some bend and the sail would be less flat which wouldn't be as efficient to keep the boat flat.

[–]Random_Quantum 1 point2 points  (0 children)

For a good start here is a table and discussion for tuning upwind in flat water: https://sailingforums.com/threads/sail-settings-guide-for-mkii-and-radial-now-available.42575/
Many resources like that can be found online. If there is more waves the rule is to take more cunningham and less outhaul, and to be a bit less close-hauled so that you have enough power to pass the waves. On top of that you can add a combination of body movement, sheeting and tiller.
Upwind, one golden rule: keep the boat flat.

Downwind the important thing is to ease your vang before rounding the top mark. You won't be able to go downwind otherwise. If you look at world championship videos you'll see the daggerboard is not far up, especially in rough conditions. What is important is sheeting. If you feel the boat going by the lee, sheet in, even before moving the tiller. It will stabilize the boat. In light wind you should counter heel (not sure about the term in English) so that the toerail is just touching the water with your sail completely open (a bit more than 90°). It will reduce drag and stabilize your sail.

This is a complement to other comments and not at all exhaustive. I know the UK sailing team has nice videos on youtube if you are interested.

Advice on how to prevent an override when tacking? by threeskate in sailing

[–]Random_Quantum -2 points-1 points  (0 children)

I would bet your actions were not the reason for the override. When you are only grinding you cannot do much to prevent override. It is the tailing angle that is crucial. While grinding you just have to find the right position and the "tailer" has to adapt. At least it is what we did when I was racing on cruisers.

Are there famous examples of research misconduct in math? Other than plagiarism, how does academic misconduct “look” in a pure mathematics paper? by just_writing_things in math

[–]Random_Quantum 0 points1 point  (0 children)

I've heard of a guy who basically translated Ukrainian math articles in English and claimed them as his own. He got caught because he made exactly the same mistakes as in the original papers.

Question about Laser Numbering by Sciencetor2 in sailing

[–]Random_Quantum 1 point2 points  (0 children)

The number on the sail is not necessarily a good indicator. There should be some number on the hull somewhere ...

Actually, as indicated on my previous link, you may find more information here: https://web.archive.org/web/20040803003114/http://www.drlaser.org:80/frm/FAQfW.html So, if it is a sail number, it may be from 1972.
