22:30 Always a loud cougher attending susskinds lectures
great quote: "better question your assumptions... question your assumptions, even the ones you think are most solid, when you get into these really paradoxical situations. and assume you are making some mistake."
people are gonna read this and say: maybe logic isn't real, let me invent my own mathematics
This is the humble vow of a high school senior: I will get to this level.
+DeltaAccel Keep working at it bud.
20 years from now, your mind will love you for the understanding you have built for it.
"Thank you past DeltaAccel"
From a guy who looked at ur playlist - you won't.
How's it going
Im in 7 grade sooo
The big Five: Polchinski, Bousso, Verlinde, Maldacena and Susskind...just missing 't Hooft ;)
So this is how it sounds when scientists talk to each other.
Susskind's got less and less patience for questions. Amazes me how they always ask questions during the presentation just for the sake of looking smart, just let the man finish then ask questions god damn it.
It's interesting - I've never seen him in front of such a hostile audience, but then this AMPS/firewall business is really controversial right now, (the EPR=ER crowd are right and the firewall crowd are wrong btw).
It's not so much questions for the sake of looking smart, more like trying to tell him flat out that he's completely wrong and in quite an aggresive/heated way.
He handles it well in any case.
An attempt to throw him off and cloud the issue im surprised. Ofcourse that wont work hes just going to look like a jackass, clearly indicated by everyone laughing at him xD
yes, u r right about that
A couple of years ago, annoyed by the interruption at 3:30, I wrote here a comment in black humor style. This was naturally intended as a fun comment, deliberately using rude language and suggesting a clearly grotesque and fictitious image of a punishment angel wearing a nazi helmet and a flamethrower, suddenly appearing in the room after the interruption. I am truly sorry because I see that a couple of years thereafter there are still people who feel offended. Even when this is an anonymous profile, I don like that and I hereby offer my apology. If I went back in time, I would write something milder and still funny like "I wish the guy who interrupts at 3:30 was suddenly tele-transported to the vegetables section of Walmart" or something similar. Of course I have never wished death by fire to anyone. I don't personally know the guy who interrupts and I don't wish anything bad to him, and I am truly sorry about those who may have feel offended.
aoflex In a lecture I definitely don't expect debate, leave that to a symposium or official debate format where the debaters agree to certain terms. If this is a lecture then ol Raphy should have been more couth and waited till the end.
starfox Well that just shows that you have no idea how science is conducted in academia.
aoflex
Negative. I am a PhD student in physics and have never debated a lecturer nor have I seen anyone attempt to debate a lecturer during their presentation as being couth. If as a student I was sitting in a lecture and someone stood up to argue I am certain many people would bemoan that person. Wait until the lecture is over.
However, perhaps this video isn't a lecture per se and is in fact a symposium of like minded peers. I don't know the details behind this event. If that's the case then I don't see anything wrong with peer to peer disagreement or debate.
starfox This is a seminar given soon after a paradox was pointed out in black hole information theory in 2012. Raphael and Lenny have disagreements over physics and are at this symposium to challenge each other openly. I too am a physics researcher. This behavior is expected on hot topics.
lol
I got a question too. If two black holes are maximally entangled and Bob can meet Alice if they jump to the opposite black holes where are singularities of both black holes going to?
crazy stuff!
"Question your assumptions ... assume you are making some mistake." L.S.
I question "linearity" and "unitarity" - taboo "probability is conserved"? maybe not
I question that you cannot send information through the ER wormhole - it can be traversable, but the EPR is then nonlinear non unitary post-quantum violating Lenny's linear unitary QM assumptions of course. I actually wrote this idea down in my 1975 pop cartoon book "Space-Time and Beyond" (E.P. Dutton). Little then did I realize it would correspond to Seth Lloyd's PCTC "computing" or to the hologram picture that Lenny developed.
There where no questions about the observed degradation of entanglement that is seen between ERP pairs that are accelerated relative to each other due to the Unruh effect. How so?
Suskind is an interesting feller, open minded and not afraid to entertain other possibilities.
He is actually rather conservative in his views regarding physics but he is without a doubt a genius.
***** That's funny, he describes himself as conservative but I guess you know more about his views than he does lol!
"Why in the world do you consider him "conservative'?"
Look into his argument with Hawking, its blatantly fucking obvious why! HE DESCRIBES HIMSELF THAT WAY as opposed to Hawking who is more radical.
As for your quiz I have received no notifications from you. Maybe a youtube fuck up?
Ask again instead of jumping to conclusions.
***** That is because I had days off up until wednesday you fucking cretin.
Try your high school level quizzes with kids. Did it genuinely take you 10 minutes to think of a problem regarding simple circuits with resistors?!?! LMAO!!!
See ya later old timer, I have more intelligent people to talk to.
***** In physics, conservative means that you take the laws of nature serious, for example like unitarity in QM or lorentz invariance in SR, you don't throw them away.
*****
Nope. Not really as Susskind shows in this video.
This stuff was going on at Giza!
Attention cameraman: You had one simple task, and that was to sit there and not fuck with the camera. You have failed spectacularly.
Must be an undergrad.
let us consider the non-linked field you have created by stating camera operator had been assigned a task independent of whether camera operator had been assigned a task be it operation of the camera or otherwise ~ given a non-existent probability-field prior to the thought which results in the statement is there a time-dependent causality which exists independent of space-time {?} ─ if there is the thought may bias or influence actuality as it occurs as well as if there is none creativity of the generation of the thought may bring into existence actuality which had no prior-causality ----- since space-time is bounded locally we may consider a non-bounded causality-field which is consequent to effect-or-fields which are not currently known such as camera operator and the probability field of his Fully Unified Causality Knowledge [FUCK] being from an officially approved operations manual rather than the influence your observation may have had on camera-operators actions and decisions → if such is the case factually then your Fully Unified Causality Knowledge effected something prior in time ← if not then camera-operator's influence-field operates independent of your Fully Unified Causality Knowledge
nicholas jordan you copy/pasted alot of that. naughty on you for plagiarism. anyway, space-time is irrelevant in regards to the camera man as his motions have extremely little impact on how his personal time syncs with time for everyone else.
define «personal-time» like skip the part about my time is valuable
Comment in particular ar 15:30 where person whom gets paid to do this states clearly «we do not even know enough to formulate the theorem»
given a non-existent probability-field prior to the «space-time» local to the presentation ▬ does a seeker dragging ten-trillion Gluons sniff any of them?
No as his a-z is finite: Bounded to locality by C ^ 2
What ever happened to EPR=ER ? It sounded like a promising breakthrough at the time. Does anyone know of resent work related to this? Or was it a dead end...
you can describe any area in space bounded by planck units because they are so small there is enough code to do it .Does not mean they do actually contain the information though its just possible to describe it. Im a bit susso on this
I uphold a man's right to get very irritated and then forgive the irritant immediately afterwards!
It's like a scolding from your mother. Lol
I watched several series of Lenny on YT about classical mechanics, SR, GR, etc. but I still don't understand a word of what he's saying in this vid. What is this actually about and is the necessary prerequisite knowledge actually obtainable and understandable for me, a curious IT student just interested in physics.
+Peter Bonnema I think it's about quantum mechanics and entanglement in particular. That signals or affects can be transmitted instantly no matter how far apart particles are. And understanding black holes with this in mind. If two particles were entangled one could be in a black hole and another outside, so that would have consequences if the particles can affect each other instantly. Personally I'm only scratching the surface of this topic. Classical mechanics cannot explain this and Einstein never accepted calling it "spooky action at a distance"
Inside the black holes there are 3-D Lissajoux entanglement energy states....
It makes me so mad how disrespectful his audience is.. let him give the damn lecture and be humbled that you get to witness it!
You should watch Unruh lecture on the same event. Lenny himself questioned a lot during that lecture.
1:10:09 Is that Juan Maldacena?
yes
If there A In; there's a Out; the house allways Win'ns
Maybe I'm Stick to Smoke signals.Good Show Tho.
If a digital word packet is sent node to node intact, it must be perfectly synchronized with the transmission and delivery system overall, as a constituent element of universal timing, to remain readable, and the same applies to any information packages in the universe as a whole in the entire wave-package.
There's no way to modulate-demodulate from one black hole to another, ..the kind of communication of readable information required for the practical applications used for demonstration/explanation purposes used in the lecture. Of course, the intention is to ask why? The wave band is out of tune.
Talking on the mobile demonstrates several stages of demodulation to modulation and back: brain to muscles in the voice box, to sound to EM, to Wi-Fi, to glass, and back at the other end, while maintainingthe integrity of the information in the moment, point to point.
The whole universe is involved QM, including BHs. If Alice and Bob meet inside BHs, then the phase alignment of their constituent atoms and sub particles might be synchronized, but the state of integration would not be recognisable to anyone, any more than staring at the end of the glass fiber carrying digital code can be heard(?)

jesus, camera dude at 5 minutes in
its not a dude, its a cat operating the cameras
I didnt get the jokes ...
Too bad for you....
"The value of pi at the event horizon of a Black Hole is two.
Have two intersecting circles represent the extent of polarity cancellation,
called entropy. In flat timespace the diameters of those equally sized circles
meet at a ninety degree angle. If those diameters have a length of one, lines
going from the lower circumferences of the circles, through the centers of the
circles, to the circumferences meeting the diameters on the other sides, their
length will be 1.618033988... each.
Now draw a straight line linking the junctions of the Phi (1.618...) lines
to complete an inverted pentagram. The Phi lines represent centripetal force;
the diameters represent centrifugal force. If the circles are merged more, when
they reach that extent of globally bent timespace where pi is 2.718..., the
proportions of the five lines will be 7, 7, 6, 6, 6. In Hebrew gematria the word
OZ, O = 70, Z= 7 totalling 77, means goat :
This was copied from the private notes of Gheorghe Rakoczy. He derived them
from old books he kept in his cellars. These book were written in precuniform
Sumerian hieroglyphics. Their pages were skin preserved by copper acetate. These
books were carbon dated to be 10,000 years old. In the caverns under Mt. Negoiu, the entrance of which was protected by a monestery build like a fortress built
inside out to keep something in, were found titanium disks, electron spin dated
to be 70,000 years old.
Have you read the Book of Enoch? It is about those "Sons of God who married
the daughters of men" mentioned in Genesis. These old books claim that these Old
Ones genetically engineered Cro Magnon Man, who could speak, from Neanderthal
Man, who was an animal who couldn't speak, with their own genes. In the Book of
Enoch, the Old Ones were condemned for giving Mankind writing and science.
A union of 50 races in this galaxy, who arrogantly called themselves "the
elder gods" took samples of Cro Magnon Man and genetically engineered Cro Magnon
Man genetics into Homo Sapiens. In the mid-Twentieth Century us kids were taught
the mystery of "the missing link", an unknown between Neanderthal Man and Cro
Magnon Man.
The "elders" regimented Homo Sapiens into orders of knighthood to
exterminate Cro Magnon Man (called the Anakim in the Bible). It was found that
all Cro Magnon Males were (are) Double Y's. This knowledge justified Double Y's
as a race of Humanity, therefore, attempts were made to erase history. The Crown
Temple in London, England (see www.freedomwriter.com...) continues to direct
orders of knighthood, and lodges, to exterminate the Anakim. But, the Old Ones
are on their way back.
How could such long distances be traveled? By quantum probability
transduction travel, which is faster than light. Quantum probability is faster
than light. Simple probability is instant. When a velocity (mechanical engineering) analogue, like
entropy production rate, in thermodynamics, exceeds its light speed equivalency,
all quantumly entangled is transduced into quantum probability. There is no need
for rockets, or flying saucers, it's more like a "star gate" .
When we can get the value of pi back down to three again, or hopefully
lower, the Old Ones can and will come, therefore, there are helicopters with
devices to notice any variances in the value of pi, and when any are detected,
disruptive transmissions are sent to slow down the polarity cancellation rate ,
which is identical to entropy production rate, to restore flat timespace. But,
even the Old Ones are advancing in technology. Soon these interferences will be
overcome!
Dr. Lisa Randall, Harvard University professor of quantum physics,
officially defined the fifth dimension as that direction through variously bent
timespaces. The more timespace is globally bent, the faster the entropy
production rate, EPR, which is identical with fast polarity cancellation rate. A
very fast polarity cancellation rate is fire. As you go into more and more
globally bent timespace the value of pi GOES DOWN. At a pi value of 2.718... all
is in flames. This is the fifth dimensional surface of the Lake of Fire. From pi
equals 3.141... to pi equals 2.718... is called the Underworld.. But,
Heaven is not in the bent timespaces called "saddle" timespaces, with pi values higher
than 3.141... for fire is impossible there, and God has fire. I don't know where
Heaven is but I sure know where Hell is.
This comment scares the fuck out of me

I'm waiting for Susskind to break out of the gravitationalist straight jacket and incorporate the Electronic Universe information into his cosmology. Not that I totally agree with Wallace Thornhill on everything. I do still believe space-time must be quantized, and that, although the universe is spatially infinite it is not eternal in time.
_"Electronic Universe"_
HAHAHAHA - rationalwiki.org/wiki/Electric_Universe
_"although the universe is spatially infinite it is not eternal in time "_
It could be finite in time but without beginning, as allowed by models with time loops...
_"Wallace Thornhill"_
HAHAHAHAHA - rationalwiki.org/wiki/Electric_Universe
_"I do still believe space-time must be quantized, and that, although the universe is spatially infinite it is not eternal in time"_
Yeah, you believe-because- *JESUS* -HAHAHAHAHA.
Hosting Susskind and then attempting a Q/A after 3:30 is ridiculous and unprofessional. Lenny has enough credibility in the world of physics to simply respect what he has to say and hold your F*cking tongue until the end.
***** I don't think he's entirely comfortable with this topic. I agree that he seems a bit agitated. It's been awhile since I watched it, but I think he mentions somewhere during the hailstorm of questions that he cannot concentrate on his lecture if he gets side-tracked by questions. I worry that he's beginning to 'lose it.' But I hope he was merely tired.
***** LOL! I am also 52! Everything we heard 'old' people say while we were 'young' is turning out to be true. Especially the following bit of wisdom:
Just wait until you're my age...and as incredible as it may seem, you won't have to wait too long ;-)
***** I think time-dilation is the effect. When we're young, we move faster ;-)
I also remember exactly where I was when I first heard of the Rutherford experiment. At the time, I was nonplussed. I thought it was kind of obvious. Quite a few years later, I realized why Rutherford was completely blown away by the results. When one knows something already, you take it for granted. If I were born a thousand years ago, I guess I would have been blown away that the Earth goes around the Sun.
***** Yes, traumatic events tend to clarify our judgment and memory. I can only imagine how the passengers of the recent airline incident felt. That will be recorded FOREVER or however "forever" lasted.
Just trying to be funny. I absolutely agree with you. We probably have a lot in common.
***** I slept on your last comment. I absolutely agree with you. The more that I learn, the less I feel that I really know. I spend a great deal of time trying to learn a topic, but when I feel like I've finally absorbed it, I tend to think that I don't understand it very well at all.
In short, the more I learn, the more I realize that I know nothing at all.
Did anyone else think [ P = 1 ] when reading the title?
No

I CAN SAFELY SAY, THAT:
The PHYSICs as we know it, it's About to collapse in a few years. .... It's seems that Physicists can Go further Anymore.
Espursion based on Leonard Cohen's attempt too publish song that is not layed into term of any common known say or words in sing or sung before ,where written such as lived in Greek island writing all the songs then took sulphate went crazy threw them in the water is perhaps comment of how no one has ever heard of his songs as unabomber skit zone mass gear if get you that,mind outs,what is giving sulphate as unknown danger write/reads too chase it into non forms that do harm to you for hearings have Versailles Europe courts here? Implausible.
Steve Bez wtf
Psychotic camera operator, but otherwise interesting lecture. To the camera person... stop it FFS!
This man's aggressive, closed and restless body language makes him an exceptionally poor educator. His dismissal of the question posed at around 3 minutes in is a disgrace; no matter how stupid the question may have been. His role is to educate, not to put down. In his role as an educator, he is failing miserably at proper pedagogy! Somebody please make this man aware!
No. He is NOT an educator. He is a scientist.
No, little boy. The moment this man teaches a class, he takes on the role of an educator.
Yeah big man, that's BS. He is just there to propose his hypothesis, so that others can review it. He is not holding a lecture
Why don't you read the description first, before embarassing yourself with such idiotic statements.
So this is how it sounds when scientists talk to each other.
