When we are calculating the cross section at 30, how are using the green dirac delta but at the same time we still have it in our final relationship?

Very good lecture❤

As calculations run back to the big bang, does the inverse square law regarding gravity also work inversley? Meaning, does the effect of gravity exponentially grow? I have a limited undertanding that fractals, the golden ratio/angle/phi, pi, and so many other things are related...but I lack the formal education and/or peers and superiors to help with understanding....could gravity be seen as the geometry of spacetime, who's dimensions shift as time goes on (dark energy expands spacetime), and determined by dimensionless points (particles), like the points of an square are dimensionless, and the shape only exists when each indistiguishable point, line, and angle meet in relation to another. And, as constants are constant, their effects are variable as dimensions of said geometry change, stronger/weaker in certain instances (areas of spacetime that have clumped together due to quantum fluctuations. Gravity, we know, is stronger as mass gets closer and closer to the same *point* in spacetime-eventually collapsing into neutron starts (potenially Neutronium) and Black holes-similar to the singularity point of the big bang. We know things vibrate, due to the Heisneberg Uncertainty Principle, and, given enough time, any possibility regardless of probability will happen. As in a neutron star, matter is vibrating and confined so closely, it has no space or time to move, until it merges into a singlularity-a point of every possibility-similar to how, in a black hole, every "path" leads to the singularity, there is no more "out", even light cannot escape--and yet there are those maps of spacetime with light cones that show that perhaps, within that infinite possibility, there is another universe! Called a White Hole...similar to the Big Bang...infinite temperature....nearly dimensionless....all the same spin, until, perhaps, the weak nuclear force aspect caused some quantum change...and...poof? Please help me educate myself and...be civil....I don't think I am a genius, I just love physics and dont have peers or superiors and my spouse is tired of discussing physics.... lets call singularity... The I-Particle....from I-Theory! Also, if singularities exist, and they are the I-particle, fundamental information, and all elctrons, for example, are one; interacting with itself throughout time as positrons and electrons....then as much as Einstein and his peers wanted to explain them away with Einstein-rosen bridge.....both would work. If Information is the only and most fundamental particle or thing, and all electrons interact with themselves, then yes, singularies could be used to travel between points, but, they would be a different reality, if for no other reason than that it has you in it from another..... www.scirp.org/journal/paperinformation?paperid=90713#:~:text=The%20I%2DTheory%20explains%20that,%E2%88%9E%20turns%20into%20A1).

Hello everyone from the pure Universe❤! Is it possible to create a working group involving students to work on a new experiment? You understand that one mind and a person are not enough? (for 119 years) By determining the constancy of speed of light, all experiments and Michelson-Morley experiments are indirect and incomplete. If the Michelson-Morley experiment was carried out on a bus or airplane and was used to determine speed. only then will this experience be direct. Therefore, Einstein does not rely on the Michelson-Morley experiment. Question. Do you have an example of such direct experience? New technologies, new research tools Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure *+reference distance* 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 500000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 94/94/94 cm, and the weight is 64 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

I counted all the stars in the sky last night, there are 4796 or 4797, I'm not sure if I counted one twice. It's amazing how big the universe is

what program/laptop do you use for making this course ?

Please find a way to communicate with the past or the future for all human. You and I are both destined to die soon. My own death may be just a fleeting moment of fear, but the death of a loved one always haunts us while we're alive. It's especially agonizing when it could have been prevented-averted accidents or curable illnesses. Light is said to be of absolute speed, and it's believed that nothing can surpass it. This was Einstein's theory a century ago, so I believe there's a 99% chance It is wrong. Even if there were an absolute scale, how could we possibly find it at the current level of scientific understanding, barely making it to the moon? Anyway, currently, electromagnetic waves, gravitational waves, electrons, ions, and such have speeds similar to or equal to that of light. Instead of saying it's impossible to do before the experiment, isn't there a way to accelerate these things beyond the speed of light to send a signal to the past? For example, using a particle accelerator, solar gravity, or the solar-earth revolution cycle. As radio telescopes and satellites and cell phones are on standby 24 hours a day, isn't there a way to speed up electromagnetic waves and communicate with the past? If we find possible ways and experiment to find out whether or not, countless repetitions will naturally reveal paradoxes. We don't need to be trapped in a paradox in advance to restrict our imagination and possibilities. Personally, I think the absolute speed of light is just a barrier in the current dimension. If acceleration is faster than light, it may appear slower in our dimension, but In reality, I think it will be possible to communicate with the past or the future through other dimensions. You are much smarter than me, so please find a way to communicate with the past or the future. My father, Kyu-dong Kim, was treated by doctors at Seoul National University Hospital for two months and passed away on April 15, 2024, due to their inadequate care. I want to see my father, Kyu-dong Kim, live to be over 100. I earnestly request it. Please allow us to communicate with the past or the future to prevent such a tragic death. Isn't striving for all human beings from every era to communicate and live together the ultimate goal of humanity? I sincerely request it once again. goal of humanity?

Interesting

Também foi legalo Prof. Salomon lembrar do tênis de mesa. Eu ganhei um torneio jogando contra ele, contra o Prof. Castilho.

Parabéns por contar a História de tão importante Instituto, onde tive a honra de fazer a minha Iniciação Científica com o Prof. Bruto Pimentel e o meu Mestrado com o Prof Zimerman .

Fantastic! Thank you for sharing this course.

thank you so much sir!! you have helped me immensely!!

Museu de grandes novidades.........., nas tá valendo✌

Fraco hein..............................., mas tá valendo

Very useful thank you

Thank you for these videos.

Take A Moment Let's relax and enjoy a genius at play 🎉 Thank you for your work No god's seen or heard in my foxhole for 46 years after 28 years in the RAF. Stay Safe Stay Free 🌎 ❤

Vou fazer uma pergunta em português por pura preguiça de elaborar em inglês mesmo. Espero que o sr responda mesmo assim kk. No exemplo das bolhas de vácuo da página 118 e 119 das suas notas de aula, aparece por volta de 1:02:16 no vídeo aparece um fator de 2 multiplicando depois de uma derivação que eu não entendi de onde vem. No exemplo anterior dá a entender que o fator de 2 só aparece depois de aplicar um par e integrar com as deltas.

I watched it all. I feel acomplished.

MUONS or nothing. Hard choice.

this helped me understand CTs so much sir. Thank you!

Hi, thank you for these amazing lectures. What is the program you're using to draw? It's got many neat functions and I'd like trying it :)

Your Homework is to learn CIG Theory and write a short paper on same. Due date is OPEN but get working.

Amazing content, thank you so much for the clear explanations.

Is this video in 1990 ??

These are by far the best lectures on QFT that I have come across! The amount of details is awesome.

You are fantastic. Thanks a lot

"Can I have ten more minutes?" ... still going strong 40 minutes later

Love every lecture that I have seen from Nima! What a brilliant person, has worked very hard, it's very intuitive, what a great sharing of ideas with us! Thank you, sir!

Would you like some visuals?

Can you start with a visual of the singularity?

nowadays the courses are also in English?

General Relativity predicts dilation, not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light". He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. Time dilation is just one aspect of dilation, it's not just time that gets dilated. There is no singularity at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely everywhere you point is equally valid. In other words, that mass is all around us. This is the explanation for dark matter. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal. The concept of singularities is preventing clarity in astronomy. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.

"... gravity in four dimensions is nonrenormalizable ..." In order to understand gravity, is it necessary to explain Milgrom's MOND in terms of string theory? I say: Professor Milgrom of the Weizmann Institute is the world's greatest living scientist. Milgrom is the Kepler of contemporary cosmology. Milgrom is 20 years overdue for a Nobel Prize. Why do I say these things? Google "pavel kroupa dark matter" and "riccardo scarpa mond arxiv". Is there now abundant empirical evidence for SUSY? Consider some conjectures: (1) There are three fundamental levels of physics: classical field theory, quantum field theory, & string theory. (2) Edward Witten is the world's greatest living theoretical physicist. (3) The main problem with string theory is that the string theorists fail to realize that Milgrom is the Kepler of contemporary cosmology. (4) There might be two fundamental forms of string theory: Bohr-Witten-Milgrom string theory and Einstein-Fredkin-Wolfram string theory. (5) Bohr-Witten-Milgrom can provide mathematical models of any plausible physics. (6) In Bohr-Witten-Milgrom string theory, SUSY is hidden in the multiverse boundary that separates alternate universes, string vibrations carry ( paradoxical) MOND inertia, and the -1/2 in the standard form of Einstein's field equations needs to be replaced by -1/2 + MOND-inertia-data-function . (7) One might think of the MOND-inertia-data-function as a form of "multiverse noise" that disrupts the mathematical beauty of Einstein's field equations. Are the preceding conjectures wrong? Google "milgrom mond inertia".

I am confused, it seems to say that deterministic chaos destroys information??

Nima is the one to bring things to the point. Why not asking simple questions. He does. It takes anybody whoever was in physics away and it sounds way more reasonable as anybody else. It is down to earth.Does anybody know whether he is with Steven Wolfram. Well it is probably not the same thing, but Grassmanian and Irriducibility might probably come together in particular with virtual particles, which, lets be honest,do not exist. Not doing any criticism to Feynman. He is indisputably the best, but probably in Quantum Physics, we are leaving the world of statistics today and make this world real.

Thank you ! <3

Hi, professor. Thanks for the lectures. It is amazing to have such thorough material available on RUclips for free. I have a question. I don't understand what you mean by "thin enough". Why is this a necessary condition for having t_i = tbar in the time slicing?

Helena Petrovna Blavatsky wrote about the Ether and the Higgs particle long before Peter Higgs. When particles become elusive and defy the laws of Newtonian physics that's the realm of the Ether where thoughts travel from one brain to the other.

Please recommend me a book for these lectures .
