@TTSSATTSR Well,string theory is hypothetical, like its name have implied.However, as we have known string theory was full of loopholes--it could never be able to explain the whole universe (yet), like the rest of the other theory.What a large sum of physicist sought right now is a 'Theory of Everything' no other theory came close to unifying the four forces, string theory(more accurately M-theory) was the closest one so far.I'm not exactly a proponent of M-theory, i'm more of a particle person.

@TheMidwestsk8ter quantum entanglement characterization, the question is on how to characterize entanglement as a resource and how to interconvert various entanglement form into others. While the problem has essentially been solved for two-party-entanglement, many open question subsists in n-party-entanglement.
@TheMidwestsk8ter LMAOOO I was joking bro, I'm not 14 and I'm not working on anything. Merely observed that a few people got pissed of at 14 year olds commenting those things so I just played along to see the response haha
I Love The Video It Can Increase My Knowledge He is a world renown theoretical physicist and uses graphs to help demonstrate the theories he is presenting.
Good, I like that you share this video, I wish success always He is a world renown theoretical physicist and uses graphs to help demonstrate the theories he is presenting.
My friend thinks string theory is a bunch of hogwash. He thinks it's science fiction. I can't wait until its science FACT! I'm going to rub it all in his face. I wonder why he doesn't believe it though... I'll ask him!
@Humaan2012 I agree! I am 13 and not afraid to admit i am not a prodigy! just simply a smart kid watching to one day help the world. now whenever i see one of those "IM 15 AND SO F****ING SMATR THN U" comments i want to tell them this. the only thing that seperate the smart from the dumb is common sense and if you brag about being smart you have no common sense just to shut your F****ing pretty little mouth and dont brag and since you wont have any common sense that means your NOT F***ING SMART
@mojo45678 You don't have to boast about your intelligence, but I'm pretty sure it's your duty as an intelligent human being to get the ignorant either educated or removed from discussions (which starts with telling them they're a fucking dumbass).
I mean, if you can hold a reasonable argument with fairly good English, then I'm not going to bash on your opinions. But if you're going to make the most terrible assumptions and spew insults, somebody has to tell you to GTFO.

If the theory is about matter in motion then the formula defines a vector.
In several vectors we see the wanders that creep into this part of cyberspace but their vectors are pointing toward null space. Thus they will learn nothing from this lecture and thankfully move on. The rest of us will be taking in considerably valuable theory that will give us ideas that are of interest in our studies.

@sjewitt22 You should watch the "Elegant Universe" It's a documentary that quite explains the notion of strings in a quite easy and effective way. I found it very interesting, so maybe you will get a better idea as well!
@noon3freak That's a good question. It depends on how rigorous the approach is. I have only been through only this video and the mathematics and theory seem like something that could be taught to undergrads, but it would have to take place after a quantum physics class at least, and I doubt it would be a mandatory course. It seems more likely to me that it is a graduate course.
@noon3freak It's part of his "Continuing Studies" series, i.e., he's designed the lecture style so that it's meant for "older students." I think what this means is usually when you think of a student you think of somebody perhaps in their twenties. These lectures are being presented to people in their thirties and forties, I believe, who may or may not have pursued a career in physics, but nonetheless want a better explanation, a more in-depth view, of modern physics.
Well, if you think that you are an amateur in physics and all of a sudden began feeling like a physicist, then you are partially right, in the sense that it is possible only thanks to Leonard's explanation meant for the layman. Try understanding the Wikipedia article and you will go into pieces.
Heh, trying to get a headstart... In four years, I hope I'll be sitting in a lecture theater listening to something like this ... And understanding it a little better (because, unlike the lying, egotistical fifteen-year-olds commenting here, this makes no sense to me.)
lol @ all the kidos posting comments about how young they are and understand all of this. if you had an exam about what was discussed in this video tomorrow you would prolly get a below 0% grade. keep on dreaming kids. in a couple years you'll wake up on the desk of your shitty desk at your shitty job and wonder : gawsh i was so smart how did i end u here?

Max Planck discovered Einstein by bring attention to his research.

Greatness is using ones greatness to advance science.
Would Leonard Susskind do the same if he knew of a research solution which was tested to be the success M-Theorist tried to achieve? The answer is most likely no. The peer-reviewed publication is posted and freely available to the world.
@MAUERBAU1 Not religion at all, religion is certain that it's correct 100% on explaining our origins and existence. This on the other hand, are called THEORIES! theories, meaning it's a proposition till proven right or wrong. Hence string THEORY or M THEORY.
@mypimpomar I'm actually agnostic, I was stating that religion beliefs itself to be 100% real. As for theories, they are mere suggestions for explaining the origins of whatever. Suggestions as if in yes another better may come along and disprove it, or i will stand true to it's content upon future research. Any who what you said and what were discussing is basic common knowledge, I believe you all just misinterpreted what I wrote.
@willwork4superpowazz "As for theories, they are mere suggestions for explaining the origins of whatever."
No they are not. A scientific theory is a tested, and verified, hypotheses. A scientific theory is backed up by evidence and makes predictions. Calling a scientific theory a "mere suggestion" is shameful.
@thisisnotanick You're right, might have sounded a bit degrading, but you must understand and take into account the number of theories that have been replaced in the past, just recently, well not that recent a theory came that if proven right, will turn physics on it's side, having to rewrite all equations and reevaluate countless theories including Einsteins famous E=mc2 along with many others. VSP is what I'm talking about, in this world theories die all the time by new ones.
@willwork4superpowazz "but you must understand and take into account the number of theories that have been replaced in the past"
This is completely irrelevant. What you take into account is the evidence. That "theories have been replaced in the past" isnt an argument for anything at all, it is pure rhetoric. It is certainly not science, by any stretch of the standard.
Theories dont "die all the time".You dont know what a scientific theory is, even after my explanation.
@thisisnotanick Oh man, you need to read more, apparently you've seen a few and are astonished by such. Obviously, a theory to be considered as such has a colossal mountain of evidence research and studies behind it that promote it's validity.
Don't die all the time? What theories do you know of? String theory, M theory and General relativity theory? Are you aware of the thousands of theories right now, just yesterday a theory in Biology was proven obsolete by a new one.
@willwork4superpowazz String theory is a conceptual framework, not a scientific theory. Just because something has "theory" in the name does not mean it is a scientific theory. The same applies to m-theory.
Obviously it doesnt matter how much you read, since you seem to read a fair amount and yet you still have no idea what you are talking about.
Give me a few specific examples of scientific theories that have died.
@thisisnotanick *Facepalm* Are you slow? Why do people need to ask for info when you have the world wide web at your disposal, just google it and read, do you need me to look info up for you? Or was that demand a crucial point of your retort. READ. Before General relativity there were countless of theories that tried explaining the orbit of Mercury, some were widely accepted though not yet solidified as such. As well as for Natural selection etc. Search contemporary theories.
@mypimpomar Newton's laws werent scientific theories, they were "physical laws". The principles in a scientific theory has to explain the phenomena. Not just make predictions.
On a side note, Newtons laws are very much in use today, for example in every single video game with physics.
@GenericLatinUsername You obviously dont know what a theory is. IE theory of evolution, Theory of relativity... For something to become a theory in scientific terms, it has to be supported by evidence
based on my opinion this theory is just half coming from einstein and the other half came from plank....as the E=mc square is derived from plank's equation
Amazingly, the Regge mass-spin relation holds also for a lot of astrophysical bodies; is there a link between strings and astrophysical structures? Is this fact an observational argument supporting string theory ? See e.g.: Brosche P., Tassie, L.J.: Astronomy and Astrophysics, vol. 219, p. 13, year 1989 and references therein; Wesson, P.S.: Physical Review. D, vol 23, p. 1730, year 1981, Massa, C.: Astrophysics and Space Science, vol. 271, p. 365, year 2000.
these m-theory nutheads are a bunch of quackadoodle fuckers. lol. All i see is 3 dimensions of space you dyslexic theoretic quackadoodle shitheads. LOL.
@twizlers12 Don't worry. I am 39, have a degree in electrical engineering, have studied quantum mechanics for a semester and even I have trouble grasping some of these concepts.
The math is very complex. Even for those of us that have taken it at the university level.
I am 15 years old i have a pritty good understanding of this and i live in cananda can anyone think of a good collage/university to go to for experimental physics like m theory? ,preferably in cananda.
@coolaids100 You're 15 so you don't even have to think about that yet. Make sure you get a 4.0 GPA, get a scholarship, join the math team or something like that and all the doors will be open for you.
With that said, if you're really ambitious you should go for American institutions like MIT or Stanford.
@vivlevivle No the down quark along with the up quark (both from the first particle family) makes up protons and neutrons in the nuclei. The anti down quark has almost the same properties as the down quark but opposite sign. The fundamental particles (Standard model) describes three families or three generations of particles with 4 particles in each. That makes up 12 particles. Now they have corresponding so called anti particles that just have opposite sign. There are 12 antiparticles aswell.
Let's just hope those students realize how incredibly privileged & lucky they are to have Leonard Susskind--not just one of the pioneers of String Theory, but also one of the most gifted Physics expositors/professors of all time--treating them to this exquisitely brilliant retrospective on the subject. It's truly amazing to bear witness to Susskind's natural ability to take a tough/nontrivial subject like String Theory & tenderize it to the point that even a physics infant can easily digest it!
@NothingMaster Yeah, but his math is always pretty messy and all over the place. He'll write something down then erase half of it and leave parts out and just say what he means, which gets the point across, but the mathematical structure is just lacking too much for me. When I watch a Walter Lewin lecture, the mathematical structure is so sound that the concepts don't really need as much verbal confirmation as Susskind gives here.
@xBl00dBrothersX I've taken classes with 38 professors. Do you think I don't know what I'm talking about? Most PhDs aren't even very happy with their lives. They are so stressed with teaching, research, conferences, personal life, etc. Most male+old professors look like this man. Some female Profs though are very young and look great! But the older men look like this man... most of the time.
@nextblain I am partially trolling. I find it quite bizarre asking "how do i get my phd in m theory" while not being bothered to spell "shud". A PhD, even a "plain" BSc implies effort. If you cannot be asked to type 4 words properly how will you put effort to get a physics degree and then go to grad school?
@redelman43199 Hardly anything to do with being smart. More so memorizing what the words mean. Doesn't take a genius to know that a meson is made of a quark and anti quark, you just read books. If you don't understand these words than yeah it won't make sense.
I've never been the biggest fan of these parmesan particles. Not my favourite kind of cheese.
Wait a minute... this video isn't about cheese!
Watching this after documentaries where everything's dumbed down with fancy visualisations so that idiots like me can understand what they're talking about makes me think... I'm gonna stick with the strings of my guitar. You go, scientists!
I was with him until he started speaking, lol. this stuff is fascinating but way over my head, I need to get back to basic physics and then come back and soak this up! great stuff!
Why does it have to be in 480dpi? Isn't that stupid?

@MAUERBAU1 Not religion at all, religion is certain that it's correct 100% on explaining our origins and existence. This on the other hand, are called THEORIES! theories, meaning it's a proposition till proven right or wrong. Hence string THEORY or M THEORY.

First of all, are you a little kid?? You cannot believe everything you hear. Religions has killed many people. Is this 100% correct?
LOL Theories are the ultimate explanations for phenomena. An example: Newton's Theory of Gravitation.
This is not a "proposition till proven right or wrong." Theories are not regarded as being true or proven. A better theory can come around.
Perhaps you can compare a proposition to a hypothesis. This is very basic science, mind you.

@mypimpomar I'm actually agnostic, I was stating that religion beliefs itself to be 100% real. As for theories, they are mere suggestions for explaining the origins of whatever. Suggestions as if in yes another better may come along and disprove it, or i will stand true to it's content upon future research. Any who what you said and what were discussing is basic common knowledge, I believe you all just misinterpreted what I wrote.

@willwork4superpowazz "As for theories, they are mere suggestions for explaining the origins of whatever."
No they are not. A scientific theory is a tested, and verified, hypotheses. A scientific theory is backed up by evidence and makes predictions. Calling a scientific theory a "mere suggestion" is shameful.

@thisisnotanick You're right, might have sounded a bit degrading, but you must understand and take into account the number of theories that have been replaced in the past, just recently, well not that recent a theory came that if proven right, will turn physics on it's side, having to rewrite all equations and reevaluate countless theories including Einsteins famous E=mc2 along with many others. VSP is what I'm talking about, in this world theories die all the time by new ones.

@willwork4superpowazz "but you must understand and take into account the number of theories that have been replaced in the past"
This is completely irrelevant. What you take into account is the evidence. That "theories have been replaced in the past" isnt an argument for anything at all, it is pure rhetoric. It is certainly not science, by any stretch of the standard.
Theories dont "die all the time".You dont know what a scientific theory is, even after my explanation.
thisisnotanick 1 week ago
@thisisnotanick Oh man, you need to read more, apparently you've seen a few and are astonished by such. Obviously, a theory to be considered as such has a colossal mountain of evidence research and studies behind it that promote it's validity.
Don't die all the time? What theories do you know of? String theory, M theory and General relativity theory? Are you aware of the thousands of theories right now, just yesterday a theory in Biology was proven obsolete by a new one.
willwork4superpowazz 1 week ago
@willwork4superpowazz String theory is a conceptual framework, not a scientific theory. Just because something has "theory" in the name does not mean it is a scientific theory. The same applies to m-theory.
Obviously it doesnt matter how much you read, since you seem to read a fair amount and yet you still have no idea what you are talking about.
Give me a few specific examples of scientific theories that have died.

@thisisnotanick *Facepalm* Are you slow? Why do people need to ask for info when you have the world wide web at your disposal, just google it and read, do you need me to look info up for you? Or was that demand a crucial point of your retort. READ. Before General relativity there were countless of theories that tried explaining the orbit of Mercury, some were widely accepted though not yet solidified as such. As well as for Natural selection etc. Search contemporary theories.

@willwork4superpowazz Personal insults wont mask your inability to back up your arguments with evidence.

I shouldnt have to justify the need to provide evidence for arguments you make.
"there were countless of theories that tried explaining the orbit of Mercury"
A scientific theory is a VERIFIED hypothesis. Now, give me a few SPECIFIC examples of scientific theories that have died.

@mypimpomar Newton's laws werent scientific theories, they were "physical laws". The principles in a scientific theory has to explain the phenomena. Not just make predictions.
On a side note, Newtons laws are very much in use today, for example in every single video game with physics.

Amazingly, the Regge mass-spin relation holds also for a lot of astrophysical bodies; is there a link between strings and astrophysical structures? Is this fact an observational argument supporting string theory ?

vivlevivle 3 months ago
@vivlevivle No the down quark along with the up quark (both from the first particle family) makes up protons and neutrons in the nuclei. The anti down quark has almost the same properties as the down quark but opposite sign. The fundamental particles (Standard model) describes three families or three generations of particles with 4 particles in each. That makes up 12 particles. Now they have corresponding so called anti particles that just have opposite sign. There are 12 antiparticles aswell.

Let's just hope those students realize how incredibly privileged & lucky they are to have Leonard Susskind--not just one of the pioneers of String Theory, but also one of the most gifted Physics expositors/professors of all time--treating them to this exquisitely brilliant retrospective on the subject. It's truly amazing to bear witness to Susskind's natural ability to take a tough/nontrivial subject like String Theory & tenderize it to the point that even a physics infant can easily digest it!
NothingMaster 4 months ago 41
@NothingMaster Yeah, but his math is always pretty messy and all over the place. He'll write something down then erase half of it and leave parts out and just say what he means, which gets the point across, but the mathematical structure is just lacking too much for me. When I watch a Walter Lewin lecture, the mathematical structure is so sound that the concepts don't really need as much verbal confirmation as Susskind gives here.
