Where is the 2nd lecture???

This is a good introduction to sc …with a demonstration as well!

My question is whether or not we could use sound to create superconductivity. Like use soundwaves and acoustics to be able to create a negative pressure on a superconductive material and environment where we need superconductivity. So there would be soundwaves that would either hit a block of material and then it would float along the path of magnetic material. The reason is that it lowers the pressure in the material due to the acoustic sound waves that make the material vibrate causing it to have substantially less/more pressure and thus be able to be superconductive with energy and electricity versus liquid nitrogen or high pressure.

Another possibility: field of entanglement requires a particle to describe just like gravity requires a graviton ... entanglement particle is a tachyon of some sort?

This goes down as one of the best lectures I have ever listened to

shame einstein

Hour and a half to cover "what we know about the big bang" Thank god I didnt find one about "what we DONT know about the big bang" I havent got a whole week to sit and watch a video.

CAN PEOPLE WITH PhD's REALLY BELIEVE SUCH RELIGIOUS GARBAGE ???? "Big Bang" & "Expanding Universe" THEORIES ! Both were published by a Belgian CATHOLIC PRIEST. Father George Lemaitre in 1927, with the blessing of the Pope. In an attempt to Hijack Science, and manufacture "Scientific proof" to prove the Biblical "Creation" Myth !

Modern physics lecturers are so boring compared to LS, what happened?

What a beautiful presentation. So elegantly inspiring introduction of concepts

Leonard, Quantum Gravity is real. We now have a working Quantum Theory of Gravity that is testable and complete with reproducible empirical experiments with the same results if repeated over and over again and again, confirmed by empirical observations in nature with 7-Sigma level results, guided by empirical laws and physical/mathematical equations that are predictive, precise and does no collapse even in high energies of Big Bang and singularity of Black Hole. FYI: Quantum Gravity or Quantum Gravitation have three types that are equivalent to and manifested by Quantum Computational Gravitation- the biggest and most powerful Computer Software Program and Hardware in the Universe and Quantum Gravitational Entanglement - a Quantum Entanglement in Macroscopic Cosmic Scale namely: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement State; 2. Quantum Neutral Gravity = Superposition Quantum Entanglement State; and 3. Quantum Gravity = Spin Down Quantum Entanglement State. More detailed information could be found on the published papers 2 years ago in London, Paris, and Zurich, online and at the two scientific Journals ACADEMIA and REAL TRUE NATURE. Alternatively, you can google the name of the author ROEL REAL ROVIRA to arrive at the published paper on Quantum Gravity. Most recently, additional two well respected scientific journals namely NATURE and the AMERICAN PHYSICAL SOCIETY APS Physical Review Journals have officially invited this author to submit manuscripts on his Research on Quantum Gravity for publication for PRX QUANTUM in preparation for a celebration for International Year of Quantum IYQ 2025 to showcase the best papers of the year.

❤Thank you very much Professor and class for beautiful lesson and lecture

I wonder if Dark Energy IS Inflation

Class prank 😂

Where is Lecture 2? 😢

I joined a magic club in the past, and a surprising they stressed learning was the entertaining aspect of the show, along with magic tricks. One thing was called your "patter", your rhythm and timing of how you spoke to the crowd... it made the difference between an ameature bloke with slight of hand tricks, and a professional magician who can be hired to entertain people... this guy's patter is the closest to Feynman's public speaking voice I've ever heard. The patter is the same, except this guy doesn't look down and regularly pause for seconds like Feynman did. He's even got the same 'back east' Jewish New York subculture accent. Love it. = )

A great lecture, thanks SITP and Mr. Sean.

This was a pretty interesting lecture altogether. Thank you Stanford and professor Steven for taking the time to do this.

Great lecture, but I did not understand one detail: At time 1:04:27 Prof Kivelson is explaining that the two paired electrons are moving in the same trajectory but in opposite direction. Can someone explain why the pair electrons should move in reverse direction along the trajectory? If there is a form of attraction due to lattice deformation by the first electron the second one should go in the same direction following the first one.

They don't know the universe is expanding they think it is expanding and that is a very big difference

“The origin of momentum creation is founded on the application of energy. Momentum serves as the initial cause of pushing and pulling. The energy, emanating from the internal core of a planet, is what gives rise to momentum, commonly referred to as gravity, and not due to the planet’s size, mass, or space-time curvature. For example, when energy is applied, it generates the necessary momentum for the actions of pushing and pulling. Without the application of energy, momentum cannot be established. Consequently, force cannot be exerted for pushing and pulling, as it lacks a physical existence. This, in turn, clarifies why force is not gravity.” ~Guadalupe Guerra

I didn't understand any of this other than that quantum entanglement may be fundamental to spacetime. I guess I'll have to wait for Brian Greene, NDGT and Brain Cox to explain it to me in terms I can understand. It's a very interesting new development if true.

LOL. Computer generated images that pretend to be space.

7 years ago traversable wormholes were no possible. No longer the case anymore. What a crazy world we live now.

It is simple quantum entanglement create extra gravity which is dark energy. Problem maybe solved. Non locality phenomena is a force contributing to space higher deformation.

The human brain is hardwired to believe everything must have a begininng our intuition common sense and every experience we have in life reinforces this belief so when we look for an explanation to the nature of the universe we are not doing so with a mind open to all possibilities we have already subconsciously predetermined that at some point the universe came into existence. And we call that point of origin the big bang. This might not be the true nature of the universe but it is the only way we can conceive it to be

And now it´s time to use LK-99 ! 😮

Probably one of Susskind's last in person classes? Has he taught in person after the whole Covid shit? If he has or is hopefully we will see new videos soon!

When is Lenny going to write up the continuation to his Black Hole book, covering the AMPS challenge, the ER=EPR response, the Fuzball paradigm of Samir Mathur, the 2nd law of complexity, etc!?

The holographic principle asserts that a volume of space can be described entirely by theory on its boundary. While this principle originated in the context of black hole physics and string theory, its potential implications stretch far beyond those domains. It's a tool that allows us to think about complex systems from a new angle. Two fields where these ideas could yield novel insights are condensed matter physics and information theory. 1. Condensed Matter Physics: Condensed matter physics deals with the physical properties of matter in its condensed phase, which includes solids and liquids. The complexity of these systems often makes them difficult to describe with traditional methods. The application of holographic methods to condensed matter systems is often referred to as "holographic duality" or "gauge/gravity duality". Essentially, it's a theoretical tool that allows us to describe certain hard-to-solve quantum systems in terms of simpler classical systems in one higher dimension. The gravity side of the duality (the "bulk") is described by classical gravity, while the quantum system we're interested in (the "boundary") is described by a quantum field theory. For example, a strongly interacting quantum system (like a high-temperature superconductor) could be described by a higher-dimensional gravitational system. This duality can help us understand phenomena like quantum phase transitions, which are notoriously difficult to describe with traditional methods. Potential Novel Contribution Idea: An important challenge in condensed matter physics is understanding the behavior of systems far from equilibrium. These include systems undergoing phase transitions or subjected to sudden changes in conditions. The holographic principle might offer a new approach to studying these systems. Exploring this possibility could lead to novel insights into non-equilibrium phenomena in condensed matter physics. 2. Information Theory: Information theory is a branch of mathematics concerned with quantifying information and understanding the fundamental limits of data compression and reliable communication. The holographic principle's assertion about the amount of information that can be stored in a region of space has intriguing implications for information theory. The holographic principle implies a fundamental limit to the amount of information that can be stored in a given volume of space, determined by the area of its boundary. This is similar to the concept of information density in information theory, which describes the maximum amount of data that can be stored in a given physical system. Potentially novel Idea: A potential application of the holographic principle in information theory is in the design of data storage systems. The principle might provide fundamental limits on data storage density, which could inform the design of future storage technologies. It may also have implications for data transmission and communication protocols, particularly in the context of quantum information. These applications of the holographic principle outside high-energy physics are still in their early stages. Exploring these directions could lead to new insights and advancements in condensed matter physics and information theory, expanding our understanding of the fundamental nature of the universe and the information it contains.

holy shit. I can't believe I understood most of it if not all!

The adverts are a killer. You can't fall asleep to this. You'll be constantly skipping through ridiculously long adverts to often.

48:00 apology

Excellent.. I wish the lecture and formulas envolved the electric field

I thought Maldecena only showed gravity emerging in an ADS space, i.e. not this universe. Has this been resolved since then, or are we still talking about gravity inside Escher paintings?

God, no, please not virtual particles crossing the event horizon... no, don't think about it that way, don't think of anything that way. The field outside the horizon is perturbed by the charged particle as it crosses the horizon. The photons that maintain the field in this state are _always_ outside the event horizon. You do not need to invoke mathematical faeries or ogres to understand this or anything else.

He couldnt talk any more quickly ?

WOW!

Extremely engaging. Wonderful lecture!

you can tell he has no idea what he is talking about, he does not explain anything.

Wo

what is missing is the discussion about charge transfer insulators. xps measurement give hints about this. a full theory has somehow to be connected to the charge transfer Energy and hubbard energy

Sean explains physics perfectly. Super job, Sean! I feel like I'm getting like 97%. Some physics teachers don't explain things so well. Maybe it's just me. Not sure. Maybe if I watch it 3x I could get 90% of it - not sure. Feynman's pretty good too, but Sean really explains things clearly.

Hasn't Penrose's Objection Reduction been making the connection between spacetime geometry and entanglement since the 80's?

This dude is in the wrong field: he should have been a movie star. Mr. Darcy; The dude in Twilight; and whatnot. Something with horses, buggies or swords and the like.

If the temperature of a black hole is less than the temp of the surrounding universe would it ever really get smaller until the temp of surrounding space is less than that of the black hole?

Going to pull your string!

What the fxck does the plank institute have to do with children? "If they (the children) don't complete the task, they go hungry" In time, wait for my full response! How do you feel? There will be temp.

What is E=MC2 is taken directly from F=ma, AS the rotation of WHAT IS THE MOON matches the revolution; AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). WHAT IS E=MC2 is dimensionally consistent ON BALANCE. GREAT. What gravity is, ON BALANCE, is an INTERACTION that cannot be shielded or blocked. Indeed, consider TIME AND time dilation ON BALANCE. What is E=MC2 is taken directly from F=ma. In fact, the stars AND PLANETS are POINTS in the night sky. c squared CLEARLY represents a dimension of SPACE ON BALANCE. Now, ON BALANCE, consider what is THE EYE. Excellent. Think. By Frank Martin DiMeglio
