Hi sabine. I know this comment is a bit out of context, but I need to hear some clear (or unclear if it's not known yet) answer. When people say quantum mechanics is "non local", isn't it a bit of a stretch? The bell and CHSH inequalities are based on (along with the """free will""" thing, but let's leave that aside) 2 statements: -locality, which means strictly the inability to change the state of B performing local operations on A -hidden variables, sometimes called realism: quantum variables are like the classical ones, they exist and have a definite value and describe the system, we just don't know them. This being said (correct me if I'm wrong), which of the hypothesis is wrong since the inequality are violated? My professor strongly asserted that surely the realism one is wrong, while the locality (in strict sense) is without a doubt conserved. But I found many books, as the Nielsen-Chuang, saying that those are both wrong. Are there any experimental proof that the locality (strictly) is violated? I can't find anything because of the fact that all papers refer to "non locality" as the whole thing, but I'm interested just in the specific aspect. Hope you'll answer, or make a video about it (even better)

Closer inspection reveals that it is a temporary sign mounted on a folding barricade. That indicates to me that it, and presumably the errant "RIGHT" paint, were meant to be a somewhat temporary solution, probably due to road construction or utility work that is expected to last a few weeks to a few months.

My impression, based on the graphic shown, is that it may be more akin to the direction of a circular wobble. Imagine rolling your wrists "inward" or "outward" while keeping your thumb pointing the same direction at all times. There is definitely some sort of chirality of circuloid motion, but nothing is strictly "spinning" nor is anything being imparted with angular momentum. I think "spin" is a deliberately oversimplified way of naming a thing so that physicists and chemists will know the property you mean without inventing a more cumbersome though accurate term.

Hey Sabine your videos have been great lately thanks

Sabine cutting through (group think) like a pro. We have to stop following the lead of random internet snarky commenters and think for ourselves. Thank you, Sabine!

I took the Einstein meme totally differently at first, much more literally: How would you even take a picture of something going faster than light? Relativity suggests FTL travel might be unachievable (I'm picking my words very carefully) so having Einstein make a skeptical and somewhat sarcastic remark about it makes enough sense for the joke to work. The fact that it's actually accurate but in a completely different (and probably unintentional) way is a delicious irony, and funny in its own right.

Wonderful sense of humour. Most entertaining 🎉and educational 🧐📖, such a great combination! Thank you 👍

9:13 im pretty sure this meme is about the electron double slit experiment where the interference pattern disappears if you detect through which hole th electron went. and the single slit defractin pattern for an electron is waaaay less pronounced than for a photon, thus the result looking much more like the classical expectation of 2 lines

Great idea for a video! It’s fun and educational at the same time.

Hi, I love your broadcast 🤗 Nevertheless, in one case, that with these plates (Schrödinger's cat), I do find it very funny and I think, that the basic idea is being shown correctly. Of course, because I am not a scientist, and had only one semester quantum-mechanics in an engeneering class, I try to explain my view in a very unsophisicated way. Why do I like that meme: the actual view is not after the experiment was performed, either it is not the state before starting the experiment. If you ask the following question: will ever anyone open the door of this cupboard? Then you have the same uncertaintity as having an atom which will decay at an unknown point of time. This state seems to me as being both, as long as no one opens the door. We already know that if we wait very long someone has to open the door (for the cat, the same situation, if you wait too long, the cat will die because of getting old). At that moment your experiment will be executed. Of cours, You are right about the glass door showing the state, but the strange feeling of the tradegy (😁 ) which is about to happen after the door opens, and the current stable state, where no tradegy yet happened, gives exactly that strange feeling of having multiple solutions at the same moment. And this seems to me the correct interpretation of the wave-function, before collapsing. 😁 Hopefully did't get it too wrong?

Hmm, do both slits smell?

I think you kind of missed the joke in some of the memes. On the Einstein one, the joke is that he's asking for _pictures_ of something that moves faster than light (and therefore can't be photographed), so he's looking smug because he wins either way. More broadly, you could say it's a comment on scientific empiricism and epistemology, along the lines of the famous "tree falling in the forest" question (often attributed to Berkeley). Can we only believe things that we have direct evidence of? Forget sound; if a tree falls in the forest and one doesn't "observe" it (meaning no _irrefutable_ record of that fall can be obtained), can it even be said to have _fallen_ at all? But really, I'd say it's just a joke about taking "pics" of something going faster than light. On the boyfriend one, I think the joke is indeed about the many-worlds interpretation. So it's not about other states _disappearing,_ it's about all other states getting mad because you didn't observe them, and therefore they don't get to be a part of your "special" universe.
