Nearly all the work Arkani-Hamed is doing was anticipated by the work of Mandelstam and others in the 1960s, except they were doing the massive case. His comments about the 1960s Analytic S-matrix folks are shameful and dishonest. But the work is good, and reviving their program.

Amazing! The little I am understanding haha

PLease turn on the closed captioning CC for this video/ Thank you.

" e to the fucking i theta " That's called passion kids

Ah uhm ah uhm ah, lol.

He is a very good teacher. I just wouldn’t want that study. Thankyou

Gutes Video! LG Matthias.

Great job

Great job

madlad!

Huh..........what?.......not a clue but interesting nonetheless......

Don't ask him to explain anything, this is what you get

43:38 "Because this is after all a subject where positivity is important"

He's lost so much weight, I hope for good reasons and not bad ones. We need him around for a long time to come.

Could somebody tell these people that they're on microphones so they don't need to shout? It's not a question of the volume: when I turn my volume down I just get this idjit shouting at low volume.

The unspoken assumption of discrete objects in empty space, and yet has a duality of probability positioning defining an energy density-intensity, has to be modified, (=>modulation/frequency amplitude), in the actual cause-effect mathematical circumstances of unity-connection of axial-tangential logarithmic singularity positioning integration sync-duration.., that is an "insideout" concept of positioning location @.dt zero-infinity instantaneous now universally. Location => density-intensity AM-FMODULES of Communication certainty. Ie comprehensible knowledge. Math-Phys-Chem and Geometry will continue to be Bio-logical in e-Pi-i sync-duration QM-TIMESPACE connectivity. The null results of MM, LHC, confirms the Doom of Spacetime.

Shout out to C.Duhr, I saw him once playing drums like a young God, when he was young and covering 'Rage against the Mashine and Nirvana with his band... Goodtimes, great guy !

Worst camera operator ever

If bigger is better, after the LHC ... Perhaps we should build a gigantic particle collider on the Moon. Send a boring machine up there to make the tunnel. Turn the ore that it produces into PV panels and superconductors. Ultimately we could build one with the Moon's radius: ~1700 km.

Nima... where’s the discussion on the philosophical aspect? Perhaps if you’d sit down with an actual philosopher of Phenomenology, you might make monumental scientific advances. At the rate and depth for which you cover topics, you’re all over the map adding nothing (so far) but rhetorical interludes.

Babble

from fermions to fermi bubbles #unifiedtheoryofcosmicplasmaphysics

You’re spinning over the same subject.

Quite far away from the "Synergetique" introduced by Renée Louis Vallée that lead me here.

Mind blowing I mean how can you come up with a geometric structure of infinity. I mean the stuff they did with fractals was pretty trippy with the little buddha looking thing.

This blew my mind here no technological use? whaaaaa? ----> 1:18:16

I think Nima is brilliant and I've always admired his willingness to highlight the shortcomings of theoretical physics but he sounds desperate here perhaps because he realizes that to "save" the current paradigm of reductive materialism is to throw a "hail mary" pass. Instead, it may be time to dump that paradigm and begin to pay more attention to scientists like Donald Hoffman and others.

"We have to find some new laws." Consider the Milgrom Denial Hypothesis: The main problem with string theory is that string theorists fail to realize that Milgrom is the Kepler of contemporary cosmology. According to Kroupa, empirical evidence demonstrates that something is wrong with the dark matter hypothesis of conventional physics. arxiv.org/abs/1409.6302 "Lessons from the Local Group (and beyond) on dark matter" by Pavel Kroupa, 2014 In order to justify Milgrom's MOND, modify Einstein's field equations with dark-matter-compensation-constant = (3.9±.5) * 10^-5, Riofrio cutoff at high-energy density, and Riofrio cutoff at low energy-density. Google "riofrio pipino" and "weinberg graviton spin". According to Weinberg, if gravitons are spin-2 particles then string theory implies that MOND is empirically invalid. This suggests that there might be an uncertainty principle for graviton spin. MOND is empirically valid and implies that at least 4 new laws of nature are needed.

"Study of Fundamental Laws of Nature, governed by still-mysterious union of Space-Time + Quantum Mechanics ... " I say that Milgrom is the Kepler of contemporary cosmology. Google "kroupa mcgaugh" and "riofrio pipino". Is Einstein's equivalence principle slightly wrong? Is our universe losing gravitational energy? Sanejouand, Yves-Henri.

Just awesome.

The universe is a big place, perhaps the biggest. Kilgore Trout cf, me: The multiverse is a big place, perhaps even bigger.

I saw him live. This dude is crazy good!

Amazing Nima !

Thank you for saving this, and sharing it!

What would this guy think about the Nirmitz incident. If he cared to study it for one hour.

Idiotic comments and pretenders. Great Lecture......

These videos are too dim. Is that in the filming and cannot be changed?

Lmao "...so I can't fuck around with minus signs." 43:48

I'm happy to see that Nima is optimistic. I am now 64 years old and hoped to see real big results come the LHC. I think its harder to stay optimistic the older you are, but I should probably be more optimistic because negative attitude has no advantage.

Not a SINGLE Nima’s model works out, all are just talking. Litmus test: deriving the natural constants of THIS universe, such as Alpha, Higgs mass, CC, Planck CMB data, etc. see tienzengong.wordpress.com/2016/12/10/natures-manifesto-on-physics-2/

I heard 978 Uhs that was tough to go through for something I know zero about. I have no life.

kzfaq.info/get/bejne/nKmZZJxmyp-1dGg.html ooooooooOOOOOOOOoooooooo

He spent the entire time talking like he only had 20 minutes to make his point...... truly awesome

Greatest presenter in physics of all time. Love his style.

Sadly, there are no accompanying notes to these excellent lectures. My only complain about Nima: he might be the one of the best living lecturers , but he always never puts out any notes for students. Does anybody know which of his many papers are closest to the content of this lecture? Where he *introduces* polytopes, canonical logarithmic differential forms, etc. like here? thanks!

Legend!

11 hours? On scattering?

At 48:42 Nima became the first physicist I ever heard swear, and I laughed so hard. May the Gods bless him and the Man leave him alone. Good talk too.

Yeah near the end there is no sound.
