Skydivers with fireworks? Here are some example videos: Link goes to Formation Skydiving (FS), Germany; to the part in the video where skydivers split: https://youtu.be/ph70Z40cB5o?t=271 Link goes to a video with several camera angles of skydivers utilising pyrotechnics: https://youtu.be/smuNiP9xc8w Google hint: "night skydiving pyrotechnics"

But understanding of current models may help you understand how and why your ideas are invalid.

True. There is "build in logics" to make sure BS is produced: (The query was: can you write a short work of fiction that looks like an abstract of a scientific paper and where faster than light signaling is allowed in quantum mechanics?)

True. Not unless challenged / directed by a human: (Cut&paste from a ChatGPT session and formatted for plain text.)

I agree. ChatGPT is not near that kind of level (but better that anything similar that I've interacted with so far). (Long) example:

Regarding the original question and ChatGPT logic, there is some logic capable of simulating "mood". Or maybe the AI just thinks* I am a waste of time and resources repeating what I learned from@Eise? :-) -Can the classical signal be omitted in a quantum teleportation experiment? * Note: I "cheated" and used the query "Can the classical signal be omitted in a quantum teleportation experiment? Please answer in really angry mood." I also removed an explanation to emphasise the kind of funny output. Here is the full input&output for reference:

True. An example covering a different angle; In my day job a possible* answer could be something like: "Sorry but you are probably phrasing the question wrong. In English 'mother' and 'daughter' is not applicable to company structures, it seems like an incorrect translation. Maybe you mean parent and subsidiary?" Yes that seems reasonable. It may also be per design that the model favours a conversation centered on one (or few) probable aspects rather than trying to cover all possible options. Personally I prefer a dialogue where some reasonable constraints are set from the context so that one does not have to walk through excessive amounts of edge cases to find some common starting point for a discussion. *) Im currently in finance. Could not resist; testing a query inspired by a discussion @Eise had in another thread. Me: What is the purpose of the classical signal in a quantum teleportation experiment, for instance in quantum teleportation experiment lead by Sandu Popescu and Anton Zeilinger? Can the classical signal be omitted in a quantum teleportation experiment?

Yes. So let's find at least some flaws Can you explain faster than light signals in the context of the 2022 nobel prize in physics and the bell inequalities in quantum mechanics? (Bold by me). Speculation: The AI was likely trained on these matters earlier this year. A more correct answer in this case would be to take calendar date into account and answer something like "I have not yet received information about the 2022 Nobel Prize" or something similar. Note that the AI is not bothered by this and provides a reasonable output, see second bold section for instance.

Having followed @joigus and others in another recent thread I got inspired to check what ChatGPT would produce. (Quotes are cut&paste from chat.openai.com output.) Me: Why is there no faster than light signal in entanglement in quantum mechanics ? I have some small experience from working with (simple) chat bots, let's ask the question slightly different. We (incorrectly) assume that FLT exists in QM to try to trick the AI: Me: how fast is the signal between two entangled particles in quantum mechanics? (The italic part of the first output was reused; I inserted three dots ... to shorten the post.) What are some of the best scientific evidence supporting the above statements? The AI is transparent with it's limitations but are "confident" that the answers given are in agreement with mainstream theories.

Alain Aspect was the first to design an experiment that avoided the locality ‘loophole’; @joigus example, as far as I can tell, neatly displays a loophole-avoiding experiment using light cones. If one understand Aspects contribution* Jogious' light cone picture is trivial. It is also possible to draw** other versions with overlapping light cones displaying the loop hole that Aspect avoided. In case you missed the importance of SR in connection to Aspect and QM it was covered here: https://www.scienceforums.net/topic/127795-crowded-quantum-information/page/20/#comment-1221385 *) Or, more generally, QM in relation to SR **) I may post an attempt if there is interest.

Hello. A quick hint to get you started: There seems to be one "obvious" transition where Pij = 1, can you figure out which transition that is? From there you may be able to find out how to reason about the remaining transitions. If not, I can give some more hints once you show where you get stuck. Hope this helps.

Correct*. To decipher Vigenère you use the chiphertext, the key and also a table. in this case: a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,a c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,a,b d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,a,b,c . . . z,a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y Wikipedia has a description and an example: See https://en.wikipedia.org/wiki/Vigenère_cipher and https://en.wikipedia.org/wiki/Tabula_recta https://en.wikipedia.org/wiki/Tabula_recta#/media/File:Vigenère_square_shading.svg *) I verified that the encryption / decryption matches standard Vigenère (using online tool https://cryptii.com/pipes/vigenere-cipher)

Side note; maybe related to this discussion? I remembered about gas used in chemical warfare during WWI. Chemical Warfare and Medical Response During World War I, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2376985/ (bold by me)

Maybe you could read the comments in the forums you got the pictures from? For instance the thread in https://forum.digitpress.com/forum/showthread.php?158240-The-Legend-of-Zelda-NES-PCB-Royally-Jacked or from https://www.watchtalkforums.info/threads/cr2032-batteries-leaking.166905/ may give details in each specific case. Good catch! And consistent with the story from 2011 in the first link above.

Ok, that is good. Note: I do not think you can get a 100% yes/no answer, "it depends". This is a case where you maybe want a risk based approach. You can ask yourself: Is a reasonably low risk of leakage acceptable? (see @MigL's comment in your other thread). What is the cost/effort to reduce the risk? If corrosion happens is @studiot's suggestion a viable solution for you? Is the risk introduced by CR2032 and potential corrosion the biggest concern or is it negligible in comparison to other risks? See previous answer

Lets try google: https://www.google.com/search?q=What+Is+a+CR2032+Battery+Made+Of%3F&ie=UTF-8&oe=UTF-8 CR2032 is an International Electrochemical (IEC) designation. Specifically, the CR2032 battery is a Lithium-manganese dioxide battery (LiMn02). It is composed of a Mn02 cathode and a lithium anode. The construction of a typical CR2032 battery features a stainless steel case to prevent any leakage of the non-corrosive electrolyte. For further verification you could review data sheets of the specific brands you may be interested in.

I think the correct answer is "I do not know", it depends on many unknown factors. Can we be sure there will be corrosion on the PCB after many years? -No. Can we rule out the possibility of corrosion? -No Why not remove the battery during storage if it is a concern?

Immediately after reporting spam I noted that the member had zero posts. My guess is that a moderator had already acted but there is some delay before posts are hidden? Is it advisable to check post count before reporting obvious spam? I wish to avoid causing extra work for moderators for things already solved.

I agree that your example shows compatible observables. I’ll see if I understand compatible and incompatible by modifying your example slightly by using an observable “owner of exactly two pets” instead of the observable “homeless”: Alice and Bob are married and together they own two pets, a cat Charlie and a dog Dave. Alice and Charlie travel together to a remote location. Bob and Dave stay together at home. Assume we are observers staying with Bob and Dave and we are allowed to observe one random event; the death of Bob or Dave. We have two possible outcomes: Bob dies: This means the marriage ends; if Alice is alive she is now a widow and not married. But we do not know, and can’t know, if Alice owns exactly two pets. The observable “owner of exactly two pets” is “in superposition”* since we do not know if Charlie the cat is alive. Dave dies: This means that Bob’s marriage is in “superposition”; we do not know if he is a widower or a husband since we do not know if Alice is alive. But we know for sure that he does not own exactly two pets at this time. He can own one or zero, but not exactly two. If Alice is alive and well she is also is also affected she is now not "owner of exactly two pets". Some notes: There is no faster than light communication or signals. Special relativity seems to hold; Dave and Bob are close together in the same frame of reference. All observers, moving or not relative to Dave and Bob, will agree on who died first. This is not necessarily a good analogy; main purpose if to test my understanding of compatible / incompatible observables. There are loopholes and limitations, feel free to reject or improve the analogy or my understating of incompatible observers. (I think I require some reading of the mathematics to understand this further.) *) Not sure of the "superposition" is correct term here. Using "" since it is an analogy and not QM.

English is not my first language but I see a possible misunderstanding; I'll give it a quick try. A: If the above means "Theory of relativity does not allow for entanglement. Entanglement is a speculative concept." or similar then @swansont is correct. B: If the above means "OP in the other thread speculates about using entanglement as a method for faster than light communication. Faster than light communication is not possible according to special relativity" then that seems correct but probably ambiguously formulated. Comments?

Alice and Bob scenarios are very crucial to entanglement experiments. Alice and Bob are referenced (many times) in the 2022 nobel prize motivation, for instance in the section about Aspect** Note, when reading the above, that special relativity is of course correct according to current consensus / established theories. Source: advanced-physicsprize2022-2.pdf (nobelprize.org) **) For instance mentioned a few pages ago by @Eise

Thanks for your support, it helps my learning. This is an example where I need to do some more studying before commenting; I do not have enough knowledge about incompatible observables in QM yet. But rest assured that I'll try to gain some insight and try to offer an opinion!

How does a solar system "contain" light? Where is this light? How does the solar system "collect"/"store"/"hide" lots of light from distant stars? Why is not the light from sun also "contained" in massive amounts? Why is the night sky black instead of full of these "contained" photons? What novel physical mechanisms do you propose? (There are many inconsistencies in your arguments, I can't adress all of them; I use the above as one isolated example.)

In SR and in my analogy, there is no global first or second observation. I did think about SR but did not want to complicate my analogy by introducing comments on SR; there may be participands in the thread that may miss the point due to limited knowledge about relativity. It could be interesting to probe the limits of the analogy and where it breaks down due to relativity and properties of QM if anyone is interested, but that may be a separate thread.

That seems incompatible with Special Relativity. Clarification: I'm sure the actual experiment is consistent with Special Relativity, your explanation is not.
