Brian Greene and Alan Alda Discuss Why Einstein Hated Quantum Mechanics
Vložit
- čas přidán 9. 07. 2014
- Albert Einstein was not a fan of quantum mechanics. He was annoyed by the uncertain, random nature of the universe it implied (hence the famous quote "God does not play dice with the universe"). So, Einstein tried to develop a unified theory that would circumvent what he saw as quantum mechanics' flaws. In this excerpt from the 2014 World Science Festival Program Dear Albert, Alan Alda and Brian Greene discuss Einstein's relationship with the "unruly child" of quantum mechanics, and how the famed physicist came up with the Special Theory of Relativity.

also would like to complement alan alda for doing his physics homework and einstein homework well enough to have a discussion with brian that bridges the gap between lay and expert.
yeah me too! but i still think that the conversation could have gone better...alan seems lost at times,in my opinion
drop expert from Brian's title and your good. nobody is an expert in metaphysics, this is not physics, this is a discussion about what physics means.
@@rodrigolara6263 He is almost 80 there, give him a break. I liked his method.
@@ronik24 yea...you are right, perhaps i was too harsh on him
@@rodrigolara6263 Alan Alda is valuable because he is the average
person who is interested but doesn't want to take the 'course'
Physicist can often be full of themselves. Alda & the
physicist Brian Greene are terrific.
For me physics is the opportunity to understand the
'mind of God"

robbiewit69 LOL!
9:58 Brian: "... Jump out a window, and then gravity goes away."
Alan Alda: "What? You jump out the window, gravity makes a quick entrance." hardest I've laughed all day.
Shows you the difference in perspective between a Physicist and a layman, lol. Words can mean completely different things.
That was Hawkeye making an entrance. LOL
The difference between a Physicist and a Comedian. Comedians live in the relative world of their own perspective.
@@DeathBringer769 he is right what goes away is WEIGHT u still have mass,as mass is the amount of substance present in you and gravity is still pulling u down.
@John Digsby well weight is nothing but mass×acceleration due to gravity so yes you need gravity to measure weight

@@tb14.7 this demonstration supported nothing, but it perfectly showed the main idea of general relativity. The free faling bottle with holes in it and water inside had the same "expirience" as the same bottle in a space whithout gravitional field. These are two invariant reference frames, and existence of those reference frames is the main idea behind general reletivity.
@@tb14.7 It completely supported it. If you are falling, you are moving freely along the curve of gravity, so you don't feel gravity. When we feel gravity we are really feeling our resistance against it. When you're in freefall, there is no resistance except maybe wind resistance. But essentially, when fully experiencing gravity, you don't feel gravity. In the vacuum of space, there is no gravity, but for people on the space station there is. The reason they float is because they're in orbit, which is just freefall. They're falling along the curve of gravity, so they don't feel it. Just like when you're in freefall on earth.
It's always worth bearing in mind that usually, whenever we think that Einstein was wrong about something, it turns out he was right all along.
Wrong, he was thinking this universe is static, observation proved him wrong, this universe is expanding exponentially.
You’re wrong. He introduced the cosmological constant in his field equations for uses with cosmology. When you look at positive values for the constant in the Newtonian Limit, you get an expanding universe. He called it his biggest blunder because he was convinced, and MANY many other people, that the universe was static. It turns out he was wrong. We have multiple pieces of evidence for this, including the recession of a supernova.
@@Godakuri the point is that the cosmological constant is still used today, because there IS an underlying force that is actually pushing our universe outwards. So, even though the constant was implemented because of a blunder, it actually proved to be the correct implementation.
Not about quantum mechanics though
@@argosron9838 that came from a mistake in his calculations of tensor calculus though didn't it? Friedmann used Einstein's own field equations to prove that the universe can expand or contract

I love science, it is art, it is imagination, it is specific, intellectual, considered, controversial, creative, psycholically impacted by the researchers and possibly the assessors. It opens up many possibilities and chaos. What a stimulating endless field.
In other words, you have no idea what science is.
+Galactic President Superstar McAwesomeville does anyone?
denise brooks yet it's so limited by limited minds true science is in The Great scientist -Göd-
if God exists, he cannot be a scientist. That is absurd.
Science starts by the recognition that we cannot have direct knowledge of the natural world, so we formulate a hypothesis about it, we test it and if it shows right we ask someone else to come to the same conclusion independently, if not, we discard it. Then we continue building on the hypothesis proven right, to build an understanding that could be demolished at any point if someone finds a condition where one of the previous conclusions fails to comply with the theory, and back to the drawing board.
If God exists, he should be the original designer with direct knowledge of the natural world. He would have the same use for science than an Olympic runner would have to a baby's walker.

Darn he explained things better than professor michio kaku....damn this explanation was worthwhile..15 minutes well spent
Michio Kaku is highly overrated, according to my physics prof.

@nineball26 swinging something around like the elevator is acceleration and the system at play which is isolated inside the elevator does attract masses...you don't know what you're talking about
@nineball26 why you don't know what you are talking about?
I'm sure Brian is making so many people smart with his explanations.
Einstein took the simple observation that light had a fixed speed ...and like pulling a thread on a sweater, unraveled all of these other equations and revelations. But Einstein viewed things as concrete and could never accept the uncertainty of quantum mechanics.
But still theorized the confirmed Bose-Einsten Condensation we make at the labs today.

I see +Max GT is a classic determinist/proponent of determinism, lol. Einstein would be happy since he didn't think the universe played dice either, even though he also came up with many things (he tried to throw out) that ended up being true that directly went against what he wanted to universe to behave like, lol. There's an old saying in Physics that goes "even when Einstein's wrong, he's usually still right" lol. Even the stuff he thought he wrong that he came up with often ended up being used later and shown to have some truth or insight there ;)

Didn't Einstein ignore all evidence pointing toward the Expanding Universe Theory because he didn't want to believe it?

Enjoy listening to that great conversation. Love physics. Brian Greene and Alan Alda are both great communicators for science. Have been following Brian Greene from the 90s greatly enjoying his book The Elegant Universe as well as his other books, appearances on science panels which I watch often on CZcams, CSPAN, PBS specials and whatever else. He is very good at conveying physics and making it clear and understandable. Love listening to him.

The title should be, "Einstein's Happiest Thought: If a person falls freely, he cannot feel his own weight!" Turn to 9:00 for this thought, a demonstration of it using water, and some comments on the role it plays in Einstein's general theory of relativity. Turn to Kip S. Thorne's book Black Holes and Time Warps: Einstein's Outrageous Legacy chapter 2, for a good telling of the way this happiest thought came to Einstein in 1907 and how it bloomed into a theory of curved space-time eight years later.
But i can't see the connection between curved space time and what he just explained, that gravity is the ground pushing against us. In the theory of curved space time, how i get it, gravity goes towards the biggest mass because it bends space and everything lighter than this mass falls in this direction where the biggest mass is, so we do fall in direction of the center of earth? But then why is there no gravity if we actually fall? Why does earth push against us? Because it's moving? Or rotating?
Gravity is a pseudo-force. You only *feel* what we call gravity if you are in an accelerated frame of reference, like we are here on Earth. Your natural free-fall is hindered by Earth pushing up against you. Einsteins happiest thought was that free falling/acceleration does away with gravity as a force; it cannot be felt or measured while falling.
One way of visualising the equivalence between gravity and acceleration is to imagine a light beam entering a hole on the side of an accelerating elevator. The light bends according to a curve. If gravity and acceleration are equivalent, gravity must bend light in the same way.
I hope to attend one of Brian greens world science festivals one day .Alan alda was or is a very underrated actor. I actually was working on a script at one time with him in mind in the leading role.
Brian Greene, he is the best at explaining (Classic physic,Quantum theory,String theory,.....)Science in general.I think one day he will surprise us with something new, we all need to understand.
( Greene joined the physics faculty of Cornell University in 1990, and was appointed to a full professorship in 1995. The following year, he joined the staff of Columbia University as a full professor. At Columbia, Greene is co-director of the university's Institute for Strings, Cosmology, and Astroparticle Physics (ISCAP), and is leading a research program applying superstring theory to cosmological questions. He is also one of the FQXi large grant awardees, his project title being "Arrow of Time in the Quantum Universe". His co-investigators are David Albert and Maulik Parikh.)....
For those who ask: the video starts at 0:00 and ends at 15:14
That's true if you are at rest. In motion, or in acceleration, the values change.
The video ends duration is only true if you're about twice the distance from sun to earth and move at the speed of about
3 x 10^8 m/s
BRIAN GREENE IS ONE OF THE BEST.
NOT TOO MANY UNDERSTAND QUANTUM MECHANIC LIKE HIM.
THANK YOU
@@tb14.7 He demonstrated the necessary. Other factors? Sure but the water doesn't feel the force of gravity. That's what he was out there to demonstrate.
There is many others who know their stuff as good as him, but he can explain these things to us dummies so good.
Two more intelligent and gracious people I have never seen having a public discussion.
11:35 I love how puzzled Alda looks at the wet floor, for a solid five seconds 😂
You don't see round earth deniers or conspiracy theorist about the earth or universe on these type videos, it's too much information for them to comprehend.
Either that or youtube doesn't recommend/suggest these videos to them. If they searched for things that could disprove their theories then youtube would give them some great suggestions. Especially now that people are putting almost everything on youtube.

Greene explains Einsteins equivalence of gravity field and accelerated frame of reference but should have taken it to next level explaining the affect of light traveling in that gravity field and how it provided the insight that gravity is the consequence of the variations of the geometry of space-time (where mass-energy tells us the geometry).
Alan Alda is brilliant. Great comic timing, and he obviously knows his stuff about physics. Great way to make it interesting and comprehensible.

I wish they would put the date on these videos.
Relativity describes the relationship between the force and the observer . . . a great deal of this discussion is pretty confounded. Gravity is simply an expression of momentum, albeit on a planetary (or cosmic) scale, and indeed the two forces (gravity and momentum) behave in an almost identical manner.
Greene seems to rush through the most pivotal portion of Einsteins discovery. When Einstein envisioned a man trapped inside of an elevator, one that was caught in free-fall down its shaft, the man inside that elevator observes an actual weightlessness as real as any scale could possibly register him in that moment (without the force of gravity acting upon his body at all.) That was actually the apex of his theory, not the man simply jumping out the window. We, observing outside of the falling elevator, know that the force of gravity is working equally upon the man as it is on the environment around him, making the negation of the force of gravity relative to his personal observation.
It is the same for an object caught in orbit around a cosmic body: The "weightlessness" an object experiences in space is actually micro-gravity, not "anti-gravity". That micro-gravity is a point of free-fall that holds its own momentum equally in tandem with that of the Earth, skirting just around the very edge of the dent the Earth's mass affects onto space/time. That relativity is the same with the water bottle: Gravity did not go away inside the bottle when it was dropped, but the force of gravity was working equally on the water molecules inside it as it was on the bottle itself. Only the observation was that of "anti-gravity". It does not matter if the observable point - and in that case the water - contains no conscious sensory organs to observe the negated effects (such as proprioception or visual orientation;) There is still a physical point which can be observed. What seems to be missed in this discussion is the objective mass of an observer (or point of observation,) and the most vital ramification of a scale registering an equal amount of applied gravitational force when the elevator is lifted, adding momentum to the already existing force generated by the Earth itself.
Quantum Mechanics never negated the empirical reality of General Relativity, and I cannot understand why Einstein couldn't see that - as Greene suggests here. I've only studied Einstein's work, not his personal life. What he actually nailed exactly was the reality of the physical universe, of gross matter, which we also know he described as being composed of energetic constituents (of course though E=MC^2.) It is those energetic constituents that defy observation, which is why pure energy particles must be considered in terms of a wave and their location deduced with uncertainty. But quantum phenomenon, such as entanglement, may very well adhere to a certain type of relativity that simply defies our current understanding of existence, being unobservable (except perhaps in their effects.) And I would bet every dime that I have, or ever will have, against there being found a "graviton" or any quantum particle to equate the force of gravity.
A particle walks into a bar ... through two different doors ... waving.
...waving... until they watch him, then collapses!

@@radiowallofsound that's it xD
13:05 Einstein reduced gravity to motion. Now we just have to reduce electromagnetism to motion and we have a theory of everything. Walter Russell has done this already and it is worth investigating.
Loved the analogy of the elvator speeding up in free space. But 8f thats the case , why does earth stops "rushing" towards you when you are above it in space ? By this theory , even if your are in outer space above the earth , the earth shoukd rush towards you ? Right ? Anyone ?
Could it be possible if unlike single particle acting as a wave can't be given a prediction but if multiple particles are taken together as one they could definitely be predicted with certainty.
Or as the number of interacting particles increase the certainty increase?
I love listening to Brian Greene, he explains things in such a clear way, even a layman (like me) can understand quantum physics at a high level.
Well the truth is that isn't really high level quantum physics, it's just 1% of 1% of the field. Quantum Physics is full of crazy math, understanding that IS hard.

+Metalmanmick13 HAHA Stop a Douchbag?
Frankly, I think Einstein was right. Once we have a grand unified theory, I think the seemingly randomness of quantum mechanics will be shown its not pure chance & probability & Einstein will be proven right. String theory or/and M theory might be the answer. Higher dimensions might explain entanglement.
I also think this. The story on quantum mechanics is not true. The Pilot Wave Theory shows that you can get exactly quantum mechanical motion from macro objects. Why don't we formulate a theory that follows the structure of the Pilot Wave Theory? Because it goes against the chaotic narrative of our times. But we could easily posit a model that creates the same observations of the double slit experiment through concise and totally explainable underlying phenomenon. I'm working on this very thing. All it is, is waves upon waves. That's what creates this seemingly "random" phenomenon.
Well if Quantum mechanics' probability can be eliminated by grand unified theorg then the physics ( classical mechanics and maxwell eqn ) will also go into trash . So you can't really overide QM *now* that it has given us many splendid results
@@shaunakmarathe86 A theory doesn't "go into the trash" when its limitations are discovered. For example, Einstein's theory of gravity superseded Newton's but calculations based on Newton's theory are still accurate enough to enable us to send probes to the moon and to other planets.

Nice, this video finally made me understand how gravity really isn't a force of attraction but, as Einstein proposed it, a warping of space time which creates an accelerating field.
thanks for pointing out that gravity is not a force of attraction.
7:00 We Grmans pronounce it quit the same, spooky / spuckig, but we stress "u" like "oo". Thx Brian
Imagine if Einstein embraced Quantum Mechanics i wonder if he would have been able to unify the forces then.
He did. He is actually known as the father of QM. He especially did a lot of Quantum statics and all other kinds of stuff. He just didn't like the Copenhagen interpertation.
Probably.
he tried to unify QM for a long time. He and many other top scientist at the time. they were'nt succesful
Keshen Govender
I think the sad part is all the time he wasted trying to unify the forces. If he had spent all that time excepting the forces could not be unified and working with those forces to develop and understand them the whole world could be ahead further. That said at least once Einstein could not unify the forces at least it stopped any one else bothering to try to do so. So I guess its as long as it is short.
@@roland20002000 No. In fact, the reason why a Unified Field Theory is impossible, at present, is because QM and Relativity are incompatible on a fundamental level. Given how much time, money and effort has been made to correct this problem, it is concievable at this stage that one of them is probably wrong.
Summary of Einstein's opinion on quantum mechanics:
"Gott würfelt nicht." - "God doesn't roll dice."
Niels Bohr: "Don't tell God what to do."
It's actually stop telling God what to do but yeah
And the dice are loaded
That reminds me of strict Christians. They are not allowed to play games using dice or playing cards because those can be used in gambling.
I've had so-called quantum physicists explain different facets of that science and contradict themselves within three sentences. They were quite secure in their explanations. Do not, under any circumstance allow a quantum mechanic to repair your car.
Alan Alda has one of the beutiful voices in cinematic history i know of. He is truly inn the likes of Swaggersoul

I love this stuff so much.... when I was younger I didn't have much interest but now I find this very intriguing
Yes me too liked more girls than physics
Correct me if I am wrong but what Dr Greene is explaining can also be explained by Newtonian Relativity i.e. in free fall, within the falling frame you experience no net force.
IT IS explained using Newtonian mechanics . He is just saying that Einstein previously was confused about this , after a while he *realised* it .
General Relativity: G(F/m)(H/m) = 7.426157905 x 10^-28 m/Kg. Special Relativity: (F/m)(H/m)c^2 = 1.
Gravity is clearly an emergent force as per #Verlinde . It's becoming more and more clear that what Einstein said, that Quantum Mechanics is "incomplete," is undoubtedly correct.

Starting to wonder what if the uncertainty in quantum physics is somehow tied to our consciousness. What if our thought/choice itself is the hidden variable upon which all these mysterious phenomenon are taking place?
Yes, exactly. That's kind of a rephrasing of the measurement problem. Bohr kind of thought what you said... I think. Trying to figure out what Bohr thought is like trying figure out quantum mechanics, 😄
uncertainity principle arises from mathematics of fourier tramsforms even without any connection to physical world.

6:45 The German words for 'spooky action at a distance' would be 'gespenstische Fernwirkung' or spukhafte Fernwirkung'. Both translations can be found in the German literature. That is because the paper where the term was first used was written in English. Einstein had emigrated from Germany and he lived and worked in princeton when the paper was published.
We can't be sure if the term really was coined by Einstein himself. The paper has three Authors. Albert Einstein, Boris Podolsky and Nathan Rosen. It was written by Boris Podolsky, most probably because of the three, he had the best command of the English language.
In a letter to Heisenberg Einstein later expressed his dissatisfaction with the published version of the article. So maybe he would not even have used those words.

Nobody could have stopped Einstein from publishing an article of his own in German, if he had been so inclined. I am not aware that he did.
Generally, I like Brian Greene, he knows his stuff but his commentary is a bit confused. Einstein's problem was indeed with non-locality, (*not* with determinism, or entanglement), entanglement just implies some correlation, not causation, and Einstein rejected non-local hidden variable theories, like David Bohm's. His position was that determinism and hidden variables would follow as a consequence of the principle or locality. Of course, we now know Einstein was wrong, not because of any experimental confirmation of entanglement (much less spooky-action-at-a-distance) but because of Bell's inequality theorem.
I think it would be more accurate to say Einstein hated the Copenhagen interpretation, rather than quantum mechanics, as-a-whole. Unfortunately, those two are used interchangeably.
I'm an Einstein fan have read several biographys and have university degree in Physics. I can tell you that, imho, Einstein hated indeterminism and hit upon non-locality as a way to demonstrate that QM was incomplete and that a complete theory would be deterministic. So it was quite the other way round from what you say. Why else would he say "God does not play dice with the universe!?"
It came as a great annoyance to people like John Bell when anyone had accused Einstein of being wedded to strictly to determinism. The EPR argument doesnt presuppose determinism and Bell's theorem does not disprove determinism. It's just not in the argument.
Here's what Pauli said to Born in a letter in 1952 _". . . I was unable to recognize Einstein whenever you talked about him in either your letter or your manuscript. It seemed to me as if you had erected some dununy Einstein for yourself, which you then knocked down with great pomp. In particular Einstein does not consider the concept of "determinism" to be as fundamental as it is frequently held to be (as he told me emphatically many times) ... he disputes that he uses as a criterion for the admissibility of a theory the question : "Is it rigorously deterministic?"..-he was not at all annoyed with you, but only said you were a person who will not listen"._
Here's what Bell said _"It is remarkably difficult to get this point across, that determinism is not a presupposition of the analysis. There is a widespread and erroneous conviction that for Einstein determinism was always the sacred principle. The quotability of his famous "God does not play dice" has not helped in this respect"_
Andrew Wells Ok good. However, that is hearsay evidence - things that other, albeit reputable, people say was Einstein's outlook. Are there any writings or quotes by/of the man himself to corroborate?
I think it's better than hearsay but, just read the original EPR paper.
Ya well your boy got OWNED by bohr at Copenhagen. and he's gonna get owned again once dark matter is discarded! then we'll see who the real gangsta is.
That water bottle tipping over at the beginning bothered me for the rest of the video
Einstein awarded Feynman and Schwinger a substantial cash prize for quantum mechanics.
6:46 -- "spukhafte Fernwirkung" . . . in which "spukhafte" may mean something more like "ghostly" (in the sense of not material . . .)
What's the Spooky word in German is stupid question!
Every word in German is spooky :P
Ja...Ja!
German, the most ugly language to exist.
Forexalised in your opinion
Did Einstein not say it in English anyway, he was bilingual and escaped to USA...
the two creatures who disliked this video should not exist on Earth
Ahmadreza777 Who are you to say what people should and shouldn't like? People may not like it because it's nonsense. Gravity doesn't go away when he drops the bottle but the water is falling down with it.
acid junkie yes, it can be explained by newtonian mechanics as well. Anyway Greene is a nice guy but didn't quite explain gravity according to the modern view
We found the two creatures here only lol
@@inox1ckOK so tell what actually is gravity by your Newtonian mechanics !
Just because it works doesn't necessarily means that it describes what the thing actually is .
@@darkseid856 He's not claiming that the experiment "explain's" gravity. The "weight" of anything (such as water) is the effect of gravity on its mass. The experiment demonstrates that when the bottle and the water are falling they have no weight. That was Einstein's insight that led him eventually to his theory of gravity. Try googling "equivalence principle".
Time also appears in this business of acceleration, or energy levels and motion. However, there is one concept missing: infinite complexity. Why? it's not math.
Explanation 👌🏼
Yet we still dont have a distinct quantum theory for gravity.
Maybe gravity is so weak because it extends through the dimensions... we don't really know how to do it yet. Maybe after confirming the gravity force (we have detected gravity waves so far) with gravitons we can find the best path for explaining the force better.
what about those trampoline experiments though
Quantum mechanics are applied to the atomic and subatomic world. Relativity handles the larger scale physical processes. Gravity is a property of space. Objects are not attracted to each other, they interact with the gravitational field according to their mass.
@@wallacegrommet9343 but then why they even form gravitational field ? Why is it that the force applied by them on another mass is always attractive ? (Unlike electrostatic force)
@@darkseid856 In principle because that's how space-time works, at least in this universe, all matter bends the space-time where it's located, in an uniformly way from it's center of gravity, expanding outwards decaying on intensity of the gravitational 'force' infinitely
Alda's voice doe
What he has a lovely voice. Yes like a cartoon character but lovely
+Michael Sleight I agree, it's fantastic.
The water does not leak for the container when it is dropped cause the water and container are dropping at the same constant rate
They are not dropping at a constant rate but at an accelerated rate.
Normal calculation: 2+2=4
Quantum computers: Perhaps...
So Newton was dropping apples and Einstein was dropping people out of windows.
🤣
I don't think Einstein was wrong about the quantum mechanics. I think what Einstein was trying to figure out was a theory that is able to describe the motion of subatomic particles when they were not interfered by human observation. Once observed, the particles are already interfered by human being's observation. Quantum mechanics best describes the subatomic world only because it can explain the result of experiments, which are all human intervention. In my humble opinion, quantum mechanics works but still a superficial theory. A deep, fundamental theory should be just one theory that explains all.
An 'observation' in quantum mechanics is just an interaction between systems, it has nothing to do with a conscious observer.
@@patriksjokvist6431 Hey Bohr, don't you mean measurement...not observation?! 'I said Observation! And that's what I Meant!' It's been known for decades that that explanation doesn't cover the empirical 'observations'. That's why we Still have the Measurement Problem.
@@aaroncurtis8545 Regardless of language, previous commenter is right. A conscious measurement or not does not need to be present to cause interference in a quantum system. If two systems interact at all, there is interference. Period. A human scientist making a measurement is just one type of interaction.
Very important comment by Brian Greene in the last paragraph of this video: "Einstein didn't use acceleration in his formulas for special relativity"! Many people forget that, even physicists when they try to explain time dilation and other special relativity effects. There are only relative speeds and different observer positions, but never acceleration. That is why special relativity only talk about energy increase of objects close to c, not mass increase as many also get wrong.
I wished this guy was my professor in college ❤️
