After watching, I decided to look for explanatory videos about LQG. And came up with 1 rather involved lecture with poor video and audio quality, and a few videos of Smolin bemoaning the poor funding LQG gets. Do a search for String Theory, and you get pages and pages of hits to lectures by active researchers explaining aspects of String Theory to all levels of folks from the general public, to physics students, to other active physicists. Perhaps LQG guys should try to get taxpayers interested.

[ragasaraswati]

Great lecture, but the audio needs compression and anti-clipping because both the dynamic range and the frequent distortion make it difficult to often hear and need constant adjustment of volume.

[MrRein1988]

Jezuz, I like the subject, but come on, speaker should talk loud and clear, and this guy looks simply shy and hard to understand

[iheartsteezeskiing]

29:50 fo sum juicy shait. Disprovin da theory of da $trings! I think I may have been converted...

[ThermalHD]

I see it over and over, science videos that have content edited out, its lame!!

1 is arround 39:22

and many times before in the video.

Scientific outcomes predicted by ST; ST Bishops will make others feel stupid. They will claim to predict & prove gravity exists.

[darcon81]

We, human race, think of present theories of String, Loop, and other unified theories as ancient philosophers like Democritus think of atomos, the indivisible particle of mater. We sim dt 1of em is ryt but so far everything is still theory and we're still far from knowing the ultimate reality. Ryt nw, we're just scratching the surface. Relying only in equations and physical experiments r lyk horses wearing blinders on a race. They think they're moving 4wd bt dey hv no idea wer deyr goin.

[sbergman27]

@darcon81 "We sim dt 1of em is ryt but so far everything is still theory and..."

No. Rather, collections of hypotheses which are mathematically consistent together. A "theory" is a hypothesis, or collection, which has withstood empirical testing to the point that we can have confidence in it. I make the distinction, since unscrupulous people often take advantage of the confusion, calling successful theories they don't like "just a theory". Very slippery and deceptive. And it really fools people.

[darcon81]

They say that T.O.E. could explain every thing but the thing is they can't even explain what are energy (ies) is causing psychic phenomena and the spirit world. Worse some of em don't even believe it. A unified theory can explain the link between the tangible and intangible matter. The dark matter and the common matter.They should combine philosophy, spirituality and science. I believe the truth lies not only in empirical knowledge alone but our innate knowledge and faith.

[ragasaraswati]

@darcon81 Well put. Einstein said imagination is more important than knowledge, and it would take a new Einstein to come up with the incredible imagination to derive the truth about quantum phenomena. Theory and experiments are the funding blocks though to which scientific philosophy can act upon. As Einstein again said, all we know comes from experience. Imagination can reveal weak links of experience and expose the true causes instead of be deluded by symptoms.

[BarriosGroupie]

Two main points:

1. Lee Smolin can't do up his tie properly

2. There are a lot of bald heads in the video.

[SpitamaFan]

Smolin's book is great. I'd recommend it to everyone. Smolin isn't anti-string. He simply writes that it's achievements have been overstated and other approaches have been needlessly pushed to the margins.

Smolin writes that string theory might indeed turn out to be right. Or it might indeed turn out to be wrong. But other approaches should also be encouraged.

[GROGANIOUS]

Doubly special relativity.

[FeelOfFriction]

He called dark energy a crisis. How can a new discovery be a CRISIS? These people are so full of shit its disgusting.

[alnot01]

@FeelOfFriction " Dark energy is a crisis because quantum field theory and general relativity do not predict a universe dominated by dark energy, energy not mediated by the exchange of known bosons.

[ricomajestic]

@FeelOfFriction Looks like the only thing full of shit is your head.

[alnot01]

This video is grounded in Smolin's book "The Trouble with Physics," which I very highly recommend.

Physics is a human community that marries paper and pencil theorists (e.g., Einstein, Weinberg) and guys who measure things in the lab and in deep space (Rutherford, Hubble). Each branch deeply needs the other. Smolin convinced me that String Theory is all theory and no lab work.

[mtheoryrules]

@alnot01

String theory can be potentially falsified and should the hadron collider cause a micro black hole that would be evidence in favor of string theory and against some other competing QFT

[bucles2000]

Keep talking about quantum-relativity,fool computer scientistist with that fantasy,I will be more rich..

[thejugglenaut91]

unsuccessful attempts? Isn't that what science is about? Failing again and again and then finding the correct answer.

[redblugreenjello]

The theorist will get the boon of data that will be coming in the next few decades of all the new measurements and cataloging we are now undertaking in all fields and the pendulum will swing the other way. this discussion is not macro enough, i fail to how hitting a momentary wall and having certain uncertainties is any kind of a problem.

[Virtueman1]

Ethical principles underlying science ...OMG what crap! This is so stupid I almost vomited. No more of this torture.

[Virtueman1]

This is because of lack of philosophy and too much out of context math ideas.

[chrisofnottingham]

I've tried watching this twice but it is just too painful. Can anyone do a summary in 500 chars? I gather form "more info" that science hasn't managed to come up with a TOE yet. Presumably there is more to this talk than that.

[painxtreme]

chris, The truth is, there are 2 theories explaining the universe and nature, and it breaks down to a gravity and energy thing, which is more difficult to explain.

Theory 1: Einstein's General Theory of Relativity - It is pretty darn close to universally correct. The problem is when you get below a milimeter from a gravitational object (we will use Earth) The General Theory falls apart. The equations no longer work.

[alnot01]

@painxtreme : The strong & weak force are effective only over intra-nuclear distances. Macroscopic objects have no net EMF charge, because of the exact cancellation of + and -. So for macroscopic objects over astronomical distances, gravity is the only remaining force and is easily tested and verified. At distances less than 1mm, gravity does not so much fail as become very difficult to test given present technologies, because it is so weak relative to EMF.

[painxtreme]

@alnot01 So are you in the camp of gravity either being sapped from our dimension (brane) by another, or being leaked into ours..or dubious about 11 dimensional hyperspace? It would explain how emf out performs it on the small scale, and honestly if gravity were much less scalable with size, it would present some interesting problems, ie. people exerting strong gravity upon each other and objects within a given size range. I will always be lost in my fascination with quantum, but it eludes me

[painxtreme]

@painxtreme  That ended oddly, Id wanted to say a lil about Quantum, but ran out of letters. Ill add more later.

[painxtreme]

I know this goes over 500 char., but it takes a little more to break it into lay terms.

Theory 2: I am generalizing a bit here. I am putting the various Quantum Mechanics into one hat, but it essentially explains what you've asked. Quantum is the physics of the very small. In Quantum world, particles behave in what we would think would be a very irrational way. They can disappear, reappearing in other locations, and some behave differently under observation. Very generalized, but there it is

[blaziermissy]

All these comments that are attacking the messenger/speaker...

Are you really that UNscientific? Don't you all know that it's stupid and holds no relevance as to negate what the speaker is saying?

Just hear him out first, but attacking him personaly is grade school immature.

Ignorance knows no bounds...

[carldepp]

People like physicists are make things happen (ex; Engineering, TV, Radio, Cars, Airplane, Computer, and etc), and can be enjoyed for people like you. BRAVO!!

Can somebody tells me this modern physics (Quantum Mechanics) is really investigate the nature of gravity (only) or else. I haven't taken this quantum courses yet. Wow i didn't know the Q Gravity theory really gave birth into a complex different theories.

[renukote]

You must learn about Ananda M. Bosman he talk about Hadronic Mechanics which is the binding force of the molecules, 10 to the -13cm

[willieofroanoke]

Typical physicist. Can't even tie his tie properly, can't stand still while taking, waves hands around excessively, makes many grammatical errors when he speaks. Babbles on and on without actually ever saying anything. I suffered through the first twelve minues in which time is said absolutely nothing of substance. I wouldn't hire this guy to dig a ditch.

[LordMalice6d9]

Well, Scientists never really were good public speakers to begin with.

The 1st Scientist to ever be a truly entertaining public educator who made science interesting even for laymen was Carl Sagan.

[alnot01]

@willieofroanoke : Smolin was never much of a college prof, and gave up teaching about 10 years ago. His strong point is the books he writes for educated lay people, and his leadership of a wonderful think tank, the Perimeter Institute. I claim he is also a frustrated economist!

[YoLninYo]

distinguished scientists, working at the frontiers of science, who can't fucking figure out how to properly record and instructional video without fucking up the audio.

BRAVO!!

[aalderma1]

@YoLninYo : Smolin didn't record or post this instructional video. The facility where he gave the lecture is responsible.

[bando8000]

Consider ... the laws of nature, our environment, and the conditions in which we journey through life may readily be understood by discovering and uncovering the underlying law of nature (singular).

Does it exist? What could it be?

The most effective and efficient approach we can take to understanding the way of all things is to question, seek out and identify this single, fundamental, underlying law of nature upon which all laws are based.

Unlikely?

What of Star-Trek's communicator?

[bapyou]

The poor quality microphone Mr. Smolin had attached to his lapel during this talk has resulted in soundtrack in which his voice is now louder (when his head is tilted downwards) and then less clear (when his head is erect). Unfortunate and poor production values.

[Anticapitalistt]

the most boring leacture I have ever listened to. It is no so much the subject but the long sentences and non-sense of this man is not nice to listen too. To be a brulliant scientists you have to have more than the knowledge;you have to have the ability to convey it in a through and communicative way especially a subject like physics or theoretical physics.

[alnot01]

Viewers, read his book The Trouble with Physics. It is a cry from the heart, by a man who is watching his beloved spouse wither and die because she has lost the plot. String theory is hegemonic, and does not speak directly to astrophysical and particle accelerator evidence. Theoretical physics has bitten off more than it can chew properly. String theory is too ambitious given the present state of techology. We should stick to GUTs and quantum gravity. AND RESPECT DATA!

[YourBooksAreWrong]

this was not as interesting as i was hoping for.  :(

i usually love reading lee smolin's theories but this was more of a history of physics lecture.

oh well...

[renukote]

You will then love Ananda M, Bosman only for advance minds

[lumajs]

I just read that the NSF people have been watching porn. But I didn't expect to find a YouTube video that shows dozens of them watching such a hardcore porn. ;-)

[9unner22]

Hot Energy(+p/rad)+Cold Energy(-e/mag)=Mass

Cold Energy? protons that have revesed their orbit? ..Entrapy of the proton.

Universe is FULL of -e(old/slowed+e). +e are emitted. + plus - = +- neutron... neutron plus neutron = mass

+-=M

Blackholes turn M back into E.

Mass(+-) RADIATES from the event horizon. neutron+- the - part is attracted to the singularity, + is repulsed, creating the flat shape of a galaxy.

Protons are emitted in beams, electrons in the opposite, Plates.

[AgainstTheRisen]

yup

[9unner22]

correction- e+ is repulsed in plates, e- e- is attracted down the poles. As far as I'm concerned matter is, (vacuum e-(+) Hydrogen in multiples

2H = He 1H + 1He (est3+6)= Li 3 6.9

2He (est4+8-) = Be 4 9.00

Hydrogen is the only true element, the others are just Hydrogen atoms combined.

[AgainstTheRisen]

Close again...however, there are interesting circumstances that do not have relavancy to black holes or hydrogen..that being the branes supplied from M-Theory that our universe is contaiend within...the place where energy starts in order to become matter. The branes functions are clearly visible in hadrons as a protons mass is not entirely made up of the quarks it contains, there is more energy too it... the same energy that is released through decay as photons (quanta of elctromagnetic energy).

[9unner22]

Correction- Black holes turn E > M

[morirmasalla]

this is what happens when a scientist speaks about "philosophy" as from within... some interesting points, but not the best exposition...  too "general" to be of interest. Bad science, bad philosophy...

[alnot01]

Most of the powerful minds I encountered as a student were mediocre teachers. Their writings were much clearer, and said all that they had to say on the subject. Over coffee and beer, they disdained polished teaching as taking time away form research, and as salesmanship over substance. Smolin is cut from the same cloth, but had the decency to move his career to a think tank. He is quite aware that his concerns nowadays are mostly philosophical. Unlike philosophers, he knows a lot of science.

[morirmasalla]

Hey alnot01,

I only said it is philosophically unsophisticated. May be he is a great scientist, but the philosophical implications... well, I think are really naive.

I retract myself saying it's bad science, but I don't retract saying its bad philosophy. There are good scientists who also are good philosophers (of physics). He is getting into philosophical issues that are highly debatable. Even if the physics, ceteris paribus, were right.

[NuyBard]

@alnot01 By the time people get to University they should be basically self-teaching. They ought to get the basics from text books and by their 3rd year of undergrad (their junior year) from the scientific literature.

[alnot01]

@NuyBard : I have been mostly self-teaching since age 16, have always believed in buying the textbook and reading it attentively, liked a lot of my texts, and began reading schoilarly stuff when I was freshman. This may describe you too, but it sure as heck does not describe most kids going through college nowadays.

Universities should save money by teaching core courses via canned lectures delivered by broadband. The YouTube model, in other words.

[zephir9]

For example, mainstream science decided before years, Aether doesn't exist, because its motion should be observable by using of light. But the analogy of light waves in vacuum are waves at wave surface and by using of such waves surface can be never observed, because is serving as a space for them already.

So, Smolin is right and science still depends on intersubjective opinion i.e. democracy - not the facts. Simply because facts are rarelly considered by science, only interpretations of facts.

[AgainstTheRisen]

pretty close to the truth

[liveguns]

he could have got his thought across in one paragraph.

a BOOK.... c'mon.

[alnot01]

@liveguns : I have read Smolin's "The Trouble with Physics." While a bit fumbling in parts (because Smolin is not a social scientist), the book overall is a masterpiece, and I very highly recommend it to all of you.

Physics is a human community that marries paper and pencil theorists (e.g., Einstein, Weinberg) and guys who measure things in the lab and in deep space (Rutherford, Hubble). Each branch deeply needs the other. Smolin convinced me that String Theory is all theory and no lab work.

[philsci1]

@alnot01 Good book overall indeed (although his fellow physicists did not like it at all, search on the net for example for Polchinsky's review of Smolin's book). But I think he can be critcized for putting too much emphasis on falsifiability. I'd say that string theory is a scientific research program (even deserving to be the first on a non prescriptive list of viable scientific programs) but nonetheless (as Smolin argues) it does not deserve the quasi-monopolistic status it enjoys today...

[arcious]

there was absolutely no point in this meeting. Everyone in this room already new everything he said, and the only reason he wrote this book was for money. which, by the way, no realy scientist would bother to buy.

[alnot01]

@arcious : Smolin's book is addressed to a readership much broader then professional physicists. You see, physics is supported by everybody's taxes. What Smolin is doing is warning us as taxpayers that by funding string theory and almost nothing else, we are not getting good value for our money.

[lumajs]

This is just amazing that downright crackpots like Smolin have a direct access of this kind to National Science Foundation. Physics will indeed be in trouble if those who decide about the organization of the institutionalized U.S. science choose to directly listen to similar pseudointellectual waste.
