I love the content, thank you for taking the time to do this, Professor! I just want to call you Brian, because I've seen so many of your lectures but hesitate to do so because I have so much respect for you. I'm not a mathematician or physicist, however, I'm fascinated by these ideas. I've been following these lessons (at my own pace, of course, because I'm trying to understand and be able to do these derivations on my own. I can honestly say that if I had been inspired by you earlier in life, I would have studied physics. Regardless, I'm still grateful for all the knowledge and insight I've gained from listening to you for some time, so once again, thank you!
Help! I need a physicist!!!! But seriously, What if the interaction of two spinning particles caused a synchronization of the spin of the particles? Something that small would spin so fast that it would take another interaction or a (relatively) long time to desynch. Would that be a way that could be explained in different words? wouldn’t that have the same effect as spooky action at a distance? The interaction synchs the spin of the entangled particles so even after they’re separated their correlated. No longer spooky. Like girls who dorm together Wesley effect if the live alone after no socially dominant female or a romantic partner in theory you would know the cycle of one according to the cycle of the other. But since they’re so much smaller theres less complexity to throw off the cycles
Following every single episode from the beginning, it just gets so intuitive and understandable, especially the derivations and implicate use of math. Being an extremely huge fan of Dr. Brian, I've watched nearly every hr long episodes from varied concepts like String theory, multiverses and it gets so beautiful and interesting. Thank you for spending some time from your busy schedule just to make such beautiful interactive videos.
Thank you for your work! I've been a pupil of Quantum Physics since 2007 officially and I use it to teach people how to manifest since we know that observation does in fact affect reality. Entanglement is what I use to show people that what happens to one happens to ALL, so kindness and love are imperative for us to BE.
Dr. Greene I hope you read these comments. Your Daily Equation vids are really helping me get through the COVID-19 home imprisonment. I’m a retired mechanical/nuclear engineer and lifelong student. Please don’t stop these, at least until life goes back to normal. 👍👏😊🙏
This is the first new thing I've learned from this series and I've gotta say, there is no better way that I would like to learn the mathematics of quantum entanglement.
Boy these lectures are fun. I feel very lucky to be able listen to these lectures. It is a real pleasure to be able to sit here at home and have my grey matter so profoundly rattled ..... (in a good way). Thank you so much for doing them at this difficult time.
I am definitely interested!! Please continue these. I had to pause it for a second just to post this after that comment. Thank you so much for your passion and time!
professor Greene can you please explain in the up coming videos about STEPHEN HAWKING's equation on identifying the area of the event horizon by the entropy of a black hole.
Professor Greene, it has been quite fascinating to learn from you about these beautiful equations and ideas. In the upcoming episodes, I would like to know about the Paul Dirac equation regarding the existence of antimatter and also about the equation that Professor Stephen Hawking asked to be put on his tombstone. Thank you professor. Your way of explaining the concepts is really quite inspiring.
Hi Prof Greene, could you do an episode on supersymmetry please! I did basic field theory and understand how symmetries are crucial for physics, but never managed to learn supersymmetry! Would love to see how it is so popular and crucial in string theory.
I'm a happy World Science Festival subscriber, but I just discovered this series! Looks like I have 13 episodes to catch up on, but "Your Daily Equation" sounds like it had a great deal of fun and interesting content! :-D Thank you for sharing such high quality content with the world!!!
Dear Dr. Greene, thank you for making these videos. I have a question regarding fields that I hope you could address. In QFT a particle is a wave-like perturbation on a field, the speed of a wave is determined by the media, but the speed of a particle is determined by the source. How these two are reconciled in QFT. QFT reconstructs the particle-like behavior by adding an infinite number of planar waves. However, in experiments we can have a particle traveling with any speed we like (less than c). On the other hand, it is known of waves that their speed is determined by the media on which they travel. I couldn't have a wave on the surface of a pond travel at any speed I like. The speed is determined by the characteristics of the pond. So, how these two are reconciled in QFT. Any pointers of where to find the answer are highly appreciated. Thank you very much, Juan.
Thank you for a great lecture professor Greene! Would you try to explain how the quantum entanglement - correlation of the states of the particles at the the surfaces of two black holes can lead to a wormhole “inside” between the black holes? Would this mean that we can in theory construct a stable bridge and travel back in time? Regards from Prague, Czech Republic!
At this moment, I’m fairly sure that there are more people wearing unpaired socks than ever before. I would like to hear more about John Bell and how he managed to show what’s happening before we look at something
Learning a lot from these talks. I also love that you have not avoid writing down some actual mathematics to back ups the ides being discussed. Keep 'em coming!
I think that some possible underlying substructure of what we consider today as 'elementary' particles, may explain these strange behaviors. And I think exactly this is what hasn't been ruled out.
What Bell's theorem ruled out are Einstein's local hidden variables. What isn't ruled out is nonlocal hidden variables. In other words, showing one of the axioms (specifically Separability) in the Einstein-Podolsky-Rosen paper was wrong doesn't imply the paper's conclusion about the incompleteness of quantum mechanics was also wrong. Proving Einstein was wrong doesn't imply Bohr was right.
@@brothermine2292 How is non-local hidden variables different from local hidden variables? My understanding is that what has been ruled out, is that the results are predetermined, that the (pre-dertermined) hidden variables simply don't exists.
All my gratitude! This is really fantastic! Rendu à un âge plus avancé, je peux enfin prendre le temps qu'il faut pour consolider mes connaissances en science...et mieux prendre conscience à quel point l'univers est fascinant...vous êtes un pédagogue hors pair!
I have seen many videos about Entanglement and on some level at least, I do understand what is being spoken about although I couldn't give a lecture lasting more than 45 seconds on it ! What intrigues me though is the actual physical process of "entanglement", how exactly are the individual particles manipulated? I just don't see how an entangled particle could be first separated from its partner and transported to some distant spot, I know I probably sound stupid but often with me, seeing a demonstration or having the technical process spelled out are the only ways I can absorb the information I seek. Thanks Brian-and BIG BIG THANKS for the WSF!
I love videos like this. Thank you. I have a couple of, probably ignorant, questions. First, what happens to the particles *_after_* you measure them? Do they spontaneously return to a “fuzzy haze” such that if you remeasure them a second time you could get the opposite result? Secondly, how do you know two particles are entangled without first measuring/observing them? Lastly, how are the particles known to be entangled then separated and moved to a different location to observe/experiment? Do scientists put them in a special box and fly one to New York and the other to California? Yes, I know the NY and CA example was just an example? But, I would assume that even in the same lab *first you have to know the particles are entangled.* Then you have to separate them some distance to verify that each is always opposite of the other and the second to be observed seemingly “decides” faster than light. This stuff is incredibly fascinating. But, I think I know how my dog feels when I try to explain algebra to him.
Q: Sin² x + Cos x² = 1 is true only on euclidean geometry. We already know that space is curved so why do we use this assumption in derivations of quantum equations?
Dr. Greene, in listening to you describe entanglement where "you somehow effect" something at a distance. It makes Everett's Many Worlds interpretation seems simpler. Question: ***What's your take on Many Worlds vs. Wave Function Collapse? ***
I’ve Solved Einsteins Riddle. Space and Time is being smashed into your face at the speed of light. Then retreating at the speed of light thus creating an illusion of time, hence backward time travel.
Thank you for your eloquent explanation of complex physical phenomena. My question is, how do we know that the spin state of the second particle changed instantly without measuring it? The experiment carried out by Alain Aspect points to yet another scenario, namely that the change in status of the second particle, in this case the polarization of the photon, only takes place at the moment when the photon interacts with the polarizer, i.e. not when the first photon is measured , because at this moment the position of the polarizer on the other side is not even set. The setting of the second polarizer occurs randomly, so the status of the second photon therefore does not depend on the measurement of the first photon, but on the setting of the second polarizer.
Sir Brian Greene! I request you to make a video about the intrinsic quantities of matter : charge, spin and mass. That we actually wanna to gain the concept of intrinsic quantities of matter into a some physical appearance..
I have two questions. According to the math, two entangled particles reveal their spin (or other measured property) the instant one of them is measured. Two entangled particles are in flux until particle 1 is measured spin up, then particle 2 is known to be spin down--mathematically. First question: are there any experiments that measure both entangled particles simultaneously? Question two: if particle 1 is remeasured, is particle 2 still entangled?
At 5:05 you say Einstein called entanglement spooky action at a distance. Yet Sabine Hossenfelder claims Einstein mentioned spooky action at a distance while discussing wave collapse upon measurement. Why do you disagree with her? Thanks.
I have a question: I understand that Einstein says that simultaneity is relative to the observer, so, some observers might or might not see the particles change spins at the same time? Does this mean that this "spooky action at a distance" is also relative?
Could you please talk about the principle of LEAST ACTION and Feynman PATH INTEGRALS in relation to String Theory or M-Theory ? I always hear you talking about String theory without ever seeing its main mathematical formulations ... It is time to see some equations of String Theory written down in action ..
the spookiness is due to the fluctuations in potential fields - that causes the probabilities to change states hence an oscillator is just humming around in its potential shell... I realised how complex potential fields are considering implications of computers... But also led me to consider how potential fields function and that is I would suggest relativistic action... Entanglement only functions where dependencies exist independence specifies just that an independent solution...
Is there anything interesting to think about if the two entangled particles are moving in relation to one another either at relativistic speeds or at slower speeds but separated by a very large distance?
Probability is a concept wrapped in a formula used to explain what we cannot YET, for certain, specify (I stated this earlier in response to one Brian's previous videos). The roll of a die IS calculatable - it's just hard... Once we ascertain what spin is based upon, many answers will follow.
I always thought the spins are like electrons and must be in opposite directions to balance each other in order to lower the MO energy...but that’s only in close proximity. The entanglement theory seems to suggest that when the particles are separated in space, somehow, they still think they are together which is broken upon measurement. I wonder if that measurement is transferred by something faster than the speed of light?
I wonder which is stranger - black holes, or quantum entanglement... We definitely don't have an explanation about why the entanglement is happening and how the particles seem to have a connection with infinite speed, right? It really seems to me, that it can be used for communications with some advance technologies, can't it?
“You do the experiment again.” Does that mean immediately after you do the first experiment or do you entangle the particles again? Because that will change the visualization to learn how it really works.
What makes the particle decide what state it chooses when we make the measurement? What is the mechanism by which the particle chooses a certain state?
Ive soved Einsteins “Spooky Action” riddle. Space and Time are being pressed up into your face at the speed of Light then returning back instantaneously thus, resulting in the illusion of time. “ Time is but an illusion.”
Entanglement. a quantum particle is a particle of an atom and molecule but what is not with both particles? Or is it only valid for those particles and not the rest?
0:47 his name comes again n again that's why he were unique person. He was such genius that , Even when he was trying to disprove any theory came up with new but working theory. Like Quantum entanglement and his biggest blunder 🤔
And that is exactly the point ... a single particle is being treated as two different particles ... Imagine you stand on one side of a river and see a pipe sticking out from the water. You are a child so you get curious about it, you reach in, grab it and start dragging. Now you see another pipe moving on the other side of the river. It is the same pipe, you just don't see the segment under the water.
I don't agree with Einstein in regards to his work on relativity, but I do agree with him regarding this. Nothing is probabilistic or random, not even the result of a die. If you knew the exact metrics that went into throwing a die before you released it, its outcome is not probabilistic. Its result will be definite. We however, are not omniscient and are bound with limited knowledge, so we are forced to the realms of describing physics in probabilistic terms.
So two electrons in the same shell are entangled since they are in each other's vicinity or being in the vicinity does not necessarily mean they are interacting?
Entanglement makes you wonder if there some other field/mechanism that travels faster hen light or provide some sort of shortcut. because 'communication' between the 2 particles is instant and does not seem to depend on distance. I think it's cool we now have computers that make use of superposition and entanglement. Thank you for the equation, I was familiar with the concept since the 90`s because of my interests in computer sciences. I never seen or understood the function, now I have some sense. Haha the socks, these things make it feel a bit personal. Thank you for that! I'm making notes and actually learning something new. In light of the current topic: Can you please talk a bit about quantum tunneling? How is a electron doing that? What is the math telling us about this behavior? Greets, From the Netherlands/Amsterdam Jos
If P1 is measured and it takes on "spin up", how do we know what P2 does? We must measure it. Wouldn't that cause it to take on an exact value to "spin down"?
Is "measurement" of quantum state of particle continuous? Can quantum state of particle (or two) be locked by the means of "measurement"? Regardless of measurement particles have some state and by "measuring" we confirm that particle can be and was in measured state and it has nothing to say about state of same particle in different moment in time or another particle in same moment in time, especially adding notions of simultaneousity.
What does taking a measurement of a particle actually mean? If a particle reacts to being measured or observed, surely it wouldn't be far fetched to imply that particle has some kind of awareness, just like us humans ( a collation of particles ) are aware and react a certain way when observed.
I'd love to see this series continue in the future, even if it's only weekly or monthly or whatever your schedule allows.

Thanks Alot to explain this topic

If P1 is measured and it takes on "spin up", how do we know what P2 does? We must measure it. Wouldn't that cause it to take on an exact value to "spin down"?
Is "measurement" of quantum state of particle continuous? Can quantum state of particle (or two) be locked by the means of "measurement"?
Regardless of measurement particles have some state and by "measuring" we confirm that particle can be and was in measured state and it has nothing to say about state of same particle in different moment in time or another particle in same moment in time, especially adding notions of simultaneousity.
I love this series, but I wish it could have been structured to include questions and answers.
There is Q&A.
What does instantaneously mean when we consider relativity?
Seems like the particles are connected through wifi!
Jokes apart, this is one of the most intriguing and beautiful topic.
What does taking a measurement of a particle actually mean? If a particle reacts to being measured or observed, surely it wouldn't be far fetched to imply that particle has some kind of awareness, just like us humans ( a collation of particles ) are aware and react a certain way when observed.
There IS a thought that elementary particles have a consciousness of their own....heard it on this platform sometime ago.
Is there a difference in gravity of the spinning particles?
This is awesome
Thank you so much 😀
is it possible two particles long distance ?
