Elegant Universe TV show streaming Video

[Integral]

Here is a link to the PBS web site. (http://www.pbs.org/wgbh/nova/elegant/program.html) where you can watch the Nova shows.

You get to see and hear the String Theory Pioneers.

[Dysprosium]

Hey thanks, Integral...this stuff is great!

[Sonty]

this is a tv station? it really goes on air not just over the net? where cand you get it and how exactly is it called?

[Integral]

PBS = Public Broadcast System
It is the only commercial free, publically supported TV network in the US.

It does not offer the pablum shown on the big three commercial networks, but shows more esoteric subject matter. Yes, this show was broadcast on Tuesday night at 8:00 pm. Since I work a 6pm-6am graveyard shift I am not able to watch it live. This streaming video is great!

Ditto.
I live in Australia, don't have a video or cable TV, so this is the only way I could easily see it. It's great to finally see and hear these theorists who I've read about for years and to feel 'connected' with fellow seekers, etc.
Thanks PBS, thanks NOVA, thanks Quicktime, thanks physicsforums, thanks www., thanks mathematicians and physicists and special thanks to the Al-mighty Creator of this somewhat 'elegant', sometimes strange, sometimes dimly 'understood' but fascinating and challenging universe. [t)] [:))] [:)]

[Rimbaud65]

Superstring theory is fascinating. Last night I watched the first hour of The Nova show online. I'll watch the rest as fast as I can, tonight probably. At the same time I'm reading 'The Elegant Universe', so together it'll be a full dose of superstring theory.

Can this theory be the unified theory long sought? Intriguing.

[KLscilevothma]

Thanks ∫, it is so cool! I've watched 3 clips already and forwarded it to my two physics teachers. I'll watch the rest of the clips later. [:)]

[lethe]

in the second to last clip, about 1/3 of the way in, they showed an interview with a guy that they claimed was e. witten. he didn t look or sound like witten to me. i think they made a mistake. did anyone else notice this?

[Brad_Ad23]

I believe the supposed Ed Witten you refer to is consistent throughout the whole program. And it does sorta sound like him too.

Anyways, while M-theory holds promise, I am still opposed to it for the simple reason it is still a theory of interactions taking place in a background spacetime. A theory of everything, and of true unification should be able to tie it all into a dynamic spacetime. LQG takes care of the dynamic spacetime bit, but is lacking in other areas. Ultimately, these two fields should converge together.

[selfAdjoint]

Brad, take a look at Urs' threads on this forum. There is at least one species of M-theory that has a dynamic spacetime.

[Brad_Ad23]

Yes, I just did a search. That particular varient of M-Theory looks promising, but as Urs himself said, it isn't quite background independent. By the very mathematical nature M-theory is formulated in, it has to be background dependent. To change this, is a step towards that union of LQG and M-Theory I mentioned. I suspect, we need to take a bit more steps in understanding the actual physics before we can truely formulate such a theory. In particular, we need to extract something meaningful and common in physics out of both M and LQG theory.

i think this guy in chapter 6 is not ed witten:


he is right before halfway of the 6th segment of the third hour. am i just going crazy? i don t think he looked like ed witten or sounded like him at all....

Ed Witten is a very gracious, soft spoken family guy with a personality physicists and mathematicians would be proud to emulate. I hope that his work will eventually yield revolutionary yet basic concepts and formulas that can be appreciated by the general public toward constructive ends.

Hey guys, [:D]

you might find our Harvard High Energy Theory photogallery useful. There are many well-known physicists among faculty and visitors (Strominger, Vafa, Coleman, Arkani-Hamed, Randall, Georgi, and others; Schwarz, Maldacena, Horowitz and many other visitors), but look at the postdocs and the students, too.

I read the three transcripts, very interesting. I look forward to the results of the tests in the atom smasher to see if any physical evidence exists for Superstring Theory, such as loss of energy to other dimensions or the supersymmetrical particles (I think this is what it's called).

Can someone answer a question for me about something that was in this show. When they get to the part where the two physicists were trying to get both of the equations to match on the chalkboard, did they say that they somehow found these other dimensions or more so that the other dimensions were required in order for the string theory to function? Because for some reason i remember the latter in which case this theory is more here-say and simply a means to get some equation to work right?

Technically one can ask what came first?..the dimensions or the Maths?
Some of the abstract mathematics of string theory do not conform to our everyday experience, for instance in order to accomodate more than the usual three-dimensions, there are Mathematical extensions..all the way up to infinite (Wittens latest paper).

Some time ago there was a general concensus that 26 dimensions was pretty much suitable for the avialable 'string' Mathematics, but if the current trend continue's then there will not be enough Dimensions in our Universe to accomodate the coresponding predicted Mathematical Dimensions!

Of course the spacetime dimensions (theorized as 9+1 until Ed Witten thought of another dimension, and then 9+1 became 10+1 spacetime's).

There are about 12 Time zones graphed onto the surface of the globe, this is for each individual nation to define their own existence with their neighbours and stops Airlines from landing planes at the same time and such!, this is a human construct for ease of correspondance, it is not a consequence say of the proximity of the Earth within the Solar System along the Galactic Arm!

yes, that is exactly how it happened. string theory gives you quantum gravity, for free. some people felt that this was such a compelling argument, that they were willing to listen to what other things that the theory was trying to tell them. one of them is that it must have 10 spacetime dimensions.

the number 10 is, as you say, just the number that makes the equations work. in this sense, string theory is more constrained than other quantum theories. other quantum theories put no restriction on what dimensions you must live in (although renormalizability may have something to say to this question)

[Hyperreality]

For some odd reasons, even after downloading QuickTime player from the specified URL (links provided on the PBS), I still can't watch the video. Everytime when the QuickTime player functions came out, it automatically closes all the windows.

What do I do?

[tenzin]

It was so hoakey and cheesey. Not to mention that many of the things they say are completely stupid. There are plenty of intellegent people out there but no more great thinkers. Physicists have forgotten how to think and become obcessed with the math.

If these physicists work hard, maybe one day they will be as smart as you.

[MythioS]

Well the only thing that bothered me was when i watched it the second time i noticed he seemed to repeat things quite a bit. Kind of like going to school next year in america and having to repeat like the last half of the last year again for the next year, but for 3 hours of shows.

It seemed like more of a history show then a physics show but how much equation can you really expect a layman such as myself to understand... (although i do wish i had a little cheat sheet that explained what all the variables represented in the final m theory)

That aside if i understand lathes reply to my question awhile back i have to have some doubts as to what this whole string/m thing really means. I mean if i can just plug a number in somewhere to make sure something else makes sense... was that really the answer to begin with or is the room painted black simply because the lights arent on?

Did anyone notice the segment where they attempted to display the analogy between Newton Gravitation and GR, in which if a star's gravitational field were removed then Newton's Gravitational field would be removed instantly, however, the GR field would only be removed at luminous velocity?

My point is that the warped field sheet they used to describe a gravity wave was displayed as a 'verted' field instead of 'inverted'. However, a GR field in this configuration could only repel mass, not attract it.

I am not certain if this was an oversight by the graphics designers, however the producers do need to pay more attention.

[laserblue]

In the mid 1980's I dreamed of watching physics video documentaries on a wireless Z-183 in a park on a sunny day and was reading Buckminster Fuller's 1969 book EDUCATION AUTOMATION in which he talked about video documentaries being available to anyone 24/7 over a wireless network. I like that PBS has made ELEGANT UNIVERSE available.
I watched the entire show but I was quite put off by the first part. There was a harsh tone to it that was quite rude. I'm not against challenging accepted ideas and assumptions but Greene almost seemed to be calling all non-physicists black dogs that he was wasting his time trying to explain String Theory to. Most physicists I know bristle if you try to cast physics into the categories of RIGHT vs. WRONG but Greene bluntly says Newton is WRONG, Einstein is WRONG and says it several times throughout the show for anyone that might have idols. Greene was quite harsh with Dr. Einstein as well. At least Dr. Einstein had the grace to ask Newton's forgiveness in his 1946 autobiography and acknowledged Newton's brilliance. Greene mentions nothing about Einstein's role in the early years of quantum mechanics which gives a distorted view of Einstein's work and the alternate field theory path he chose to follow towards establishing a new foundation for physics. Physicists of the early 1900's were just as interested in finding a unified theory as String Theorists of today. Attempts to base all of physics on mechanics failed as did attempts to base all of physics on electromagnetism. Einstein's forte was statistical mechanics and he noted not one problem in the foundations of physics but two. A.I. Miller comments on this on page 137 of his analysis of the Special Theory of Relativity.
Dr. Einstein acknowledged his weakness in mathematics but had a great instinct for physical principles.
In the early 1900's there were great physicists like Ernst Mach that were still skeptical about atoms having a physical existence just as today there are doubts about strings being physical. Einstein was very impressed with kinetic theory and statistical mechanics and his Phd dissertation sought to show the physical existence of atoms in Brownian motion.
There are numerous instances of Einstein's contributions to atomic theory and quantum mechanics from his photon analogy with gases in his photoelectric paper and his use of a principle to quantize the action of electronic orbits, that turns out to be an optico-mechanical resonance principle, to the idea of stimulated emission of radiation. However, Einstein had very good reasons for parting company with quantum mechanics as formulated by Bohr and Heisenberg.
Sure, Minkowski and Hilbert could run mathematical circles around a lazy dog like Einstein, but physics is not mathematics.
You and I have the advantage of hindsight and far more information that men like Dr. Einstein did not have access to. To talk about others being WRONG is not constructive physics at all. As Poincare said, "Ruins may still be good for something." and "One geometry is not more correct than another, only more convenient."

[lumidek]

Dear laserblue,

I think that I know Brian Greene better than you do, and I am absolutely sure that he did not want to compare the dog to the other people (non-physicists). Brian is an extremely peaceful person, and he was trying to ask a profound philosophical question whether the humans - all humans, including you - are able to understand the intellectual design underlying Nature at the deepest level.

The dogs might have some problems with learning GR, but his attempt to teach the dog Einstein's equations was not meant as a humiliation of non-physicists! We should not be paranoic, I think. The program was assuming that the spectators view themselves as humans who are much better in maths than the dog - they are on the same side as Brian. I apologize to all dogs who are reading this post - it was not meant as an attack on you either.

Also, you had to watch another show if you think that the show was not respectful to Newton and Einstein. These are probably the two biggest heroes of physics, and the show displayed this fact pretty clearly and presented the whole classical physics as a conflict between the ideas of these two Gentlemen. Their theories are still deep and pragmatically speaking true - they are just not true if we want to understand the more fundamental workings of the Universe. Once we want to ask some questions about high-velocity, large mass, or on the contrary, about the microscopic world, then Newton's, Einstein's, and other ideas are simply WRONG.

Let me repeat the word once again, because it is very important. These theories, despite their magnificent success during the centuries, are not quite right. They're WRONG. I think that it's amazing how these old Newtonian ideas - that used to look so obviously true to us - can be so terribly wrong once we probe the questions beyond the everyday life. The fact that we are making progress, that we are making to show that the previous images of reality are incomplete, obsolete, and not quite true, is simply amazing, and it shows both the depth of reality as well as the power of human creativity and curiousity. I have no idea how can someone be unimpressed or even irritated by the amazing progress that allows us to show that Newton and later also Einstein and others were wrong. I am sure that most people who wanted to watch a program like that - both scientists as well as non-scientists - were sharing this fascination by our ability to challenge the paradigms that seemed so obvious in the past.

You must have misunderstood the program if you complain that the program wanted to suggest that Einstein did not contribute the key contributions to the search for the unified theory. It was the whole point and the main thread - a little bit poetic and artificially flavored thread - of the program to show that this quest for the unified theory is Einstein's baby, and the string theorists are simply following his dreams, although with a bit more modern and sophisticated (and more quantum) tools.

All of us admire Einstein. For some of us, he's like God, for some of us, he's a human being who could have flaws but who has essentially started modern physics as we know it. His instinct was amazing, but it is simply true that his research in field theory after General Relativity had been finished was misled, and there were other important discoveries, too - some of them turned out to be very deep and true despite Einstein's negative feelings about them.

I disagree that Einstein had good reasons to be skeptical about quantum mechanics as formulated by Bohr, Heisenberg, Dirac, and others. Einstein was simply wrong, even though it is easy to share his mistaken point of view. In attempts to advocate his wrong opinion, he (co)discovered some interesting physics - namely the EPR effect - but this interesting physics eventually made it even more clear that Einstein's opinions were not correct. The current interpretation of quantum mechanics might be slightly more acceptable for Einstein, but it is conceivable that he would have problems even today. Einstein has started the revolution on many fronts, and he had certainly all the rights to be wrong.

All the best

Thank you

[laserblue]

Thanks for your reply Lubo and for being civil about it.
I understand the point Greene was trying to make with the dog.
The show was o.k. It was interesting. Thank you Mr. Greene and company!

It's just that I got bad vibes from the first part. Everyone knows Newton was wrong and Maxwell was wrong and Einstein was wrong. Planck even thought Einstein was wrong about quantizing the electromagnetic field and maybe he was. Some people consider that to be the very essence of science - Continually learning we were wrong, unlearning that and relearning something new. I was wrong about Einstein's doctoral dissertation which was entitled "A New Determination of Molecular Dimensions"."It shows how to calculate Avogadro's number and the size of molecules" (http://pup.princeton.edu/titles/6272.html.).
There was a lot of emphasis on General Relativity in Elegant Universe and a very specific interpretation of it (which is popular but not the only possible one) but nothing about Einstein's contributions to Quantum Mechanics and atomic theory.He was clearly looking for a unified theory in several directions at once in his prime.
Anyway, saying so and so was wrong adds nothing constructive for me. It's amazing that men of creative genius could ever be so right in the first place!

[laserblue]

I took another look at HOUR 1 to see if perhaps I was being too harsh towards McMaster's script.
What bothers me about the first hour is the melodramatic and confrontational tone of the script.Maybe this is a good thing to get the attention of modern young upstarts but it paints a picture that isn't very faithful to reality. It's a caricature at best. The first few minutes sound like some kind of murderous horror crime story about to be told, rather than a little chat between the host and audience. (O.K, so I looked at the back of the book first.)
The portrait of Albert Einstein that is presented to a first time viewer is a very sad one. He comes across as a deluded crackpot in the first section ( A THEORY OF EVERYTHING?). The phrases used such as "...relentlessly sought...", "...a notepad close at hand...,(as though he thought of nothing else), "FURIOUSLY trying to come up with the equations...", "convinced he was on the verge of the most important discovery in the history of science..." are the way most people would describe an obsessed crackpot.The scene of someone up late at night pacing reinforces this view. Don Pendleton wrote a fictional novel "CATACLYSM" with this kind of insomniac character that wrote equations down "that would choke a computer" and was dismissed as a unified theory crackpot by the other scientists who were not from Palomar Observatory.
In the other sections of The Elegant Universe, the phrases used are confrontational such as "...squaring off with the father of gravity...", "flew in the face", "the young upstart", and "still working his day job". It makes for good docudrama one has to admit but Einstein certainly never saw it this way.At most, he made a minor modification to Newtonian Mechanics just as Lorentz made minor modifications to Maxwell's theory.
Finally, he is "left behind". A tragically sad one hit wonder who came up with RELATIVITY and nothing after that as far as one is told. He apparently wasted the last half of his life chasing an impossible dream.There is no mention of his papers on the photoelectric effect (for which he won his Nobel Prize),brownian motion, specific heat,quantization of the action of electronic orbits,stimulated emission of radiation etc.
I might agree with the idea that Einstein hit a wall in his later years, but the same problems in the foundations of physics that he worked on are still with us after a good century and still not solved to everyone's satisfaction.(See Philippe LeCorbeiller's projection into the future in CRYSTALS AND THE FUTURE OF PHYSICS in Sci.Am. 1953). As a man of creative thought, Einstein did about as much as one man could possibly do in his day. If only he could have looked at the back of the book!

Einstein has not questioned the correctness of the predictions of quantum theory, he has questioned the completeness. I see no evidence that this position is wrong. I see also no evidence that the EPR criterion of reality is wrong.

That a more complete description is possible is proven by Bohmian mechanics. You may like it or not, you cannot deny its existence.

The violation of Bell´s inequality proves that a realistic theory
cannot be Einstein-causal. For a realist, it simply means that violations of Bell´s inequality are indirect observations of violations of Einstein causality.

[ZapperZ]

I probably should have just let sleeping dogs lie, but against my better judgement, I will jump into this one... :)

The one major disappointment, but not surprising, of The Elegant Universe (both the book and the TV documentary) is the omission of the significant point of view of the Anderson-Laughlin-Pines (ALP) "axis". It appears that, at least in the documentary, the only dessenting view was presented by Sheldon Glashow (which, BTW, was one of the rumored reasons why he left Harvard for BU - that he thought most theorists at Harvard in that field have abandoned phenomenology in favor of String, Superstring, etc...)

The ALP axis (as I would like to call it) contradicts the popular views among particle/high energy physicists, championed by Steven Weinberg, that the unification of all the 4 basic forces that includes the varification of quantum gravity, signifies a "Theory of Everything" (TOE). This point of view was alluded to several times in the documentary - that getting GR and QM to mearge would mean a TOE.

ALP - who are all condensed matter theorists and who are well-known in their own rights (Anderson and Laughlin are both Nobel Laureates) - argues that what Weinberg is arguing is not a TOE for physics/universe, but a TOE for REDUCTIONISM. A grand unified theory (GUT) would only be a complete explanation of the behavior of the universe at the elementary, single-particle scale, but not does not necessary mean that we have a complete description of all the phenomena in the universe. ALP points out that there are so-called EMERGENT phenomena that can't be explained simply by knowing all the elementary interactions and by simply adding more and more interaction - i.e. this isn't simply a matter of higher complexities. As Anderson likes to say "More Is Different!"

In his Nobel speech, Laughlin described an exercise he once did onto his poor, unsuspecting students taking a graduate class in QM.[1] He gave the students a take-home exam in which he asked the students to derive superfluidity from First Principles - meaning knowing the full set of microscopic equation of motion, derive the phenomena of superfludity. Of course, the students could not, and no one can! Superfluidity, superconductivity, fractional quantum hall effect, magnetism, phase transition, etc, etc., are all "emergent" phenomena that occur as a collective effect. These phenomena disappear, as Laughlin points out, when you take the system apart and analyze each individual component within the system. These are many-body effects that simply can't be "derived" with the individual properties as the starting point.

Condensed matter physicists have long known of this, and various principles that came out of condensed matter, such as the Higgs mechanism and the principle of broken gauge symmetry, have now been adopted in various other fields of physics, including particle/high energy. However, the fact that these emergent phenomena are different and not simply just added complexities, seem to not have been heard by many camps, especially among popular views. I think it is why those who are working in the field of quantum gravity, string, etc, still may have an impression that such unification signifies a TOE. ALP have clearly pointed out why such notion may be a fallacy.[2,3] A unified theory doesn't not imply a theory of everything.

Anyway, didn't mean to throw a wrench into the whole thing, but I feel that it should be pointed out that eminent and large number of physicists do not share the same philosophical view on GUT=TOE thingy.

This point of view was alluded to several times in the documentary - that getting GR and QM to mearge would mean a TOE.

Just because a particle or interaction has not be observed in the lab yet does not mean that it does not exist. A TOE would have to go further than just uniting the forces and explaining the known particles. It would have to prove from first principles that there are no other forces or particles even possible. And to prove that something does not exist requires justifying the first principles that say is does not exist. That justification cannot rely on observations to date, for that would be circular reasoning. So the only thing you're left with is having to derive physics from logic itself.

I'm not even sure if the point you are bringing up has anything to do with what I posted. I certainly have no argument in the sense that there is a separate issue in terms of justifying that there are no other fundamental forces.

What the ALP axis promotes is that, even IF we know all the fundamental forces, even if we know all the interactions, we still do not have the ability to explain everything based on such knowledge. The higher-order emergent phoenomena can't be derived that way. Thus, even if the universe has 4, 5, 6, 7, etc fundamental forces, and if they are all unified into one consistent theory, this is still not a "theory of everything", because "everything" has to include the emergent phenomena and it has already been shown that there are no one-to-one derivation of such things.

My explanation here may not be as succinct as that already presented in the references I gave.

Zz.

[Mike2]

Could a reduction of entropy account for these "emergent phenomena"? For all the phenomena you mention represents emerging states of order. Does particle physics account for entropy?

[ZapperZ]

I'm not sure what or why particle physics have anything to do with this, since the emerging phenomena that I cited are all in condensed matter physics. In many of the emergent phenomena, such as superconductivity and superfluidity, the transition into those phenomena is a phase transition, typically a 2nd order phase transition. In such cases, there need not be any change in the thermodynamics state variables, or equation of state.

I assume it to be part of an intentional 'trick' to see how observers (veiwers) perception matches their ability to take information in?..I do recall the part of the video in question was about 'Quantum-interpretations', but anyway give me a couple of hours so I can watch my video again, and I will get you the full quantified version that I was trying to convey, of course you could just e-mail the editors and find out why such an obvious mistake got past the cutting room floor?..my opinion is that it was intentional :smile:

You may incorporate this 'insight' into your lecture if you wish

[cronxeh]

It was so hoakey and cheesey. Not to mention that many of the things they say are completely stupid. There are plenty of intellegent people out there but no more great thinkers. Physicists have forgotten how to think and become obcessed with the math.

perhaps you should learn how to spell before you start criticizing those professionals in their respected fields?

[DirtyDan]

I thought the special was OK, and I personally learned a lot, but the repetitiveness did seem a little....______(fill in the blank) :rolleyes: As for quicktime, if you had trouble watching it (I did, damn hard to get linux to cooperate with quicktime, esp. in a browser) Try downloading the videos from the posted link, they worked for me. I had trouble in windows with the video crashing my browser too, not sure what the cause. Hope that helps you

lol sorry i didn't see this earlier again my post past its due date anyway thanks for the response

Yea this is kind of a late post, but the movie was ... well wow, I thought I was watching an infomercial, 3 hours of selling a product called string theory only to be told its M-theory in the last hour. As is it's only somewhat informative, I think they could have done a better job explaining some of the ideas instead of repeating the name 100+ times (I think we got that its called string theory). Sequance is everything.

[DivineNathicana]

I thought that the special effects were really amazing, but there was not much information incorporated. One could pick up the gist of the theory, but it was nothing at all like the book. Plus, Greene got really annoying... I somehow got the impression that he is really conceited. Is it just me? haha

[misogynisticfeminist]

It indeed show us the intriguing possibilities of strings such as parellel universes and the like and I wished that it would have been a little more technical, but I think that its almost like a commercial selling ST.

[DivineNathicana]

Read the book - it's a lot better and a lot more technical.

[Tom McCurdy]

Indeed the book and movies only share the name in common. The movie is dumbed down quite a bit, but its effects are very trippy. Its fun to watch with friends who have minor interest in physics... although buy or rent the dvd don't huddle your friends around a streaming video. I really enjoyed talking to people about the movie, although usually their interest in string theory lasts about a week or so before they start running in fear of me mentioning membrane to them when they see me. The book is more technical and it can be read at a variety of paces. I was going snail's pace for the longest time... page/10 minutes or so taking careful notes... but I lost all them so I may finish the last bit sometime. Its very good book but right now i am streched thin speaking of which sleep would probably help me get better.

[Omid]

Execuse me experts may I ask what's spring theory ?

[mal4mac]

To see "the other side" check this resource site for Roger Penrose, it has links to a lecture of his (if you want video):

http://www.321books.co.uk/reviews/the-road-to-reality-by-roger-penrose.htm

[semiphor]

PBS = Public Broadcast System
It is the only commercial free, publically supported TV network in the US.

It does not offer the pablum shown on the big three commercial networks, but shows more esoteric subject matter. Yes, this show was broadcast on Tuesday night at 8:00 pm. Since I work a 6pm-6am graveyard shift I am not able to watch it live. This streaming video is great!

It's free of commercials, but not free of commercialism. They imply that they only live by what people donate - HA! They make 100's of millions on sales of their TV shows' merchandise as well as licensing rights.

That's ok - free market enterprise is what the US is about also, but it's the facade of acting like they need constant donations b/c they are a "poor" station thereby they live solely on public donations is a laugh. Greedy is as greedy does... or "Greed is good if your a socialist."

[semiphor]

It was so hoakey and cheesey. Not to mention that many of the things they say are completely stupid. There are plenty of intellegent people out there but no more great thinkers. Physicists have forgotten how to think and become obcessed with the math.

...totally agree with you. I thought the show was written for a 3 year old.

But they are obsessed with the math b/c they have no insight into quantum mechanics... as does no one - even Einstein was lost in the fuzz. So math is a crutch that every theorist is going to use until a spark occurs that points them in the right direction. In Einstein's day there was the ether drift, Planck's constant, and wave mechanics (J.J. Thompson noted that the cathode rays emitted in his vacuum tube behaved as if they had a mass - so he called them electrons).

So the show was cheesey, yes, but the theorists are indeed struggling with the best information they have (aka 'nothing' :) about the underlying structure of reality.

[Engineering_Lo]

Read the book - it's a lot better and a lot more technical.

I finally after an eternity, got the book and so far. It's so much more involved than what I've been watching. *sighs* makes having the dvd seem quite dissapointing now.

[Alex]

I have the same problems as some of the other users in this forum with watching the videos - the quicktime stream (both the regular and full-screen versions) keep crashing my browser (tried in firefox as well as ie) and the realtime stream is itsy bitsy. How are you guys viewing the quicktime version??

[p_branes]

Isnt a sequel to the elegant universe coming or has it already arrived?

[selfAdjoint]

Greene has pubished The Fabric of Reality. It isn't a sequel, exactly... It has been discussed a couple of times on PF. Do a search on the title.

Actually that was written a few years back by a UK physicist named David Deutsch.

Well never mind, the quicktime version only works with older versions of quicktime.

[selfAdjoint]

What kind of connection do you have? I use ie with cable access, and it works.

Added: I have Firefox on my home computer, to read the String Cofeetable equations. I haven't tried to view videos with it.

[DivineNathicana]

Actually that was written a few years back by a UK physicist named David Deutsch.

He meant The Fabric of the Cosmos by Brian Greene, and that's already out. I have it, but haven't started it yet. It looks promising.

[Magneto]

Hello everyone, I just joined the forum, it looks like it will be fun. I'm an average Joe interested in why everything in the universe is like it is.

It was nice to see the movie over the net on my own schedule (and free) since I just started reading the book. I had to view using Realplayer also since the Quicktime crashed on my PC too. It would be nice to see more programs like this available to public without someone trying to make a greedy profit from it.
A friend recommended reading The Fabric of the Cosmos as well. He said he enjoyed it more the The Elegant Universe
Maybe since the The Fabric of the Cosmos doesn't go as much into Quantum Mechanics, it won't make my head ache trying to visualize what the author is stating!

[Hyperreality]

The reason why Quicktime crashes on the program is because the newest version Quicktime 6.5 has a bug.

Download any verion of Quicktime older than 6.5 will work nicely.

P.S. I don't think Apple website provide older version of Quicktime anymore, older version can be found easily using Google.

[kernelcracker]

I don't know if this is going to get me flamed or not, but..
Everytime I tried to watch the video, my browser would crash.
So I did a little research, and with the help of slashdot.org, wrote a script that would print out the files. Then use wget to get it.
Here is the list.

Also uploading a text called elegant.txt, and just use wget -i elegant.txt.

I do this not to pirate, but cause I could not watch them with out having my browser crash, and see people have the same problem.

I didn't really understand what to do with what you gave us KERNELCRACKER.
I am have the same problem, and i really want to watch these. So please could u tell me what to do with what you gave us. tkx.

Hello,

Just right click on the links above, and save target as, and it will download the files to your harddrive. All the files together is about 300 megs worth.

[gordon]

i had the same problem about wieving these nice video about elegant universe. Can i ask a question about how you got these link. There is some other realmedia link. There R.Feynmann introduce us his theory about QED. İf you answer me i ll be glad very much.
thanx

[prutser]

i had the same problem about wieving these nice video about elegant universe. Can i ask a question about how you got these link. There is some other realmedia link. There R.Feynmann introduce us his theory about QED. İf you answer me i ll be glad very much.
thanx


These are the links to the realmedia streams (actual video only! :tongue:).. extracted from the .smil files.

Here is a link to the PBS web site. (http://www.pbs.org/wgbh/nova/elegant/program.html) where you can watch the Nova shows.

You get to see and hear the String Theory Pioneers.
I am fakhradin sefatpanah.I studied physics in kurdistan university.
I am very glad to see your link(URL=http://www.pbs.org/wgbh/nova/elegant/program.html)
thank you.

[Shekwan]

oh, I'm doing a research paper on superstring theory, and I have used the document as a source, can anyone tell me when did the program first air?

[FeynmanMH42]

Am I right in thinking that Greene and Randall dated in high school?
... probably not. ^_^

[linhtm]

How can i do to download all them ?

[Mattara]

I just love this 3 hour documentary about the elegant universe.

linhtm, you cannot download them due to copywrite issues.

[Raza]

How small is the "string" compared to an atom?

[linhtm]

thats stupid:biggrin: .string is only a imagination tool ,atom is matter:biggrin:

[selfAdjoint]

How small is the "string" compared to an atom?


It's not absolutely pinned down, but one relationship I've seen offered is Planck Length : string length :::: string length : proton diameter.

[FeynmanMH42]

If a string was the size of a proton, then the proton would be the size of the Earth. And the Earth would be the size of the entire observable Universe.

[Schrodinger's Cat]

Check the PBS website.



I just saw this miniseries and I have to say that it was quite interesting. String theory is indeed seductive. LOL

[Dcase]

The series was recently rerun on PBS.

Greene stated that the shortest distance between two points is a straight line [paraphrased] - which is technically correct only in the plane.

A geodesic is shortest distance between two points in curved space with the straight line the geodesic of the plane.

[pibomb]

I read the book, The Elegant universe, and liked it. Although string theory seems a little stechy when it comes to sub-planck lengths, it overall does seem like an unproved version of the T.O.E.

[Nariad]

It is really great stuff. I should add this to the Romanian portal of popularization of particle physics I created for Clubul Fizica particulelor-portal de popularizare a fizicii particulelor: http://fizicaparticulelor.ro
