1. What was the name of the song in the beginning? Who is the artist?
2. It is a puzzle of the universe that a man who teaches quantum mechanics has not worked out that a new shirt needs ironing .
3. Is this really a theory or should multiverse be called multiSPECULATION. ? Not only is it not testable , It's not even a yet workable theory. Furthermore if you change the physics in any one of the multiverses you are not insured the behavior you expect would follow the laws of your universe since the physics have changed. In this case the fine tuning issue of the cosmological constant is multiplied by the number of multiverses since you don't know what the new physics demands in the other universes. It's not a question of taking it seriously but a question of a formal working theory. General Relativity is an example of a theory. It can be tested. It predicts things, and it wasn't sitting on the shelf very long collecting dust before it was spectacularly tested with a solar eclipse in 1919 considering it was published in 1915.
4. That the arguments against multiple worlds support singular control of platonism

   " Abstract
   This is a critical review of the literature on many-worlds in
   terpretations (MWI), with arguments drawn partly from earlier critiques by Bell and Stein. The essential postulates involved in various MWI are extracted, and their consistency with the evident physical world is examined. Arguments are presented against MWI proposed by Everett, Graham and DeWitt. The relevance of frequency operators to MWI is examined; it is argued that frequency operator theorems of Hartle and Farhi-Goldstone-Gutmann do not in themselves provide a probability interpretation for quantum mechanics, and thus neither support existing MWI nor would be useful in constructing new MWI. Comments are made on papers by Geroch and Deutsch that advocate MWI. It is concluded that no plausible set of axioms exists for an MWI that describes
   known physics."
   
   Ever since Hume, science has imprisoned us in the dark cave of materialism and blind empiricism and needs to restore us to the quantum sunlight of plato (plotinus) - see my website https://independent.academia.edu/RogerClough or search in Google with a search term such as Clough platonic theory of mind Site: https://independent.academia.edu/RogerClough
5. This guy has some serious problems!
6. Excellent.
7. Merci Monsieur Arkani-Hamed !
8. I can't get over his brand new shirt.
9. 12:05 is where he describes the problem that Dennis Kim had with Seldon's research into string theory, before being distracted my chocolate milk, in TBBT lol!
10. Nima is thinned down and healthy now.
11. Fascinating!  I for one will double take this one in.
12. W against T, reference required. #conspiracyofscience
13. I quite enjoy Nima's insight. For those who are interested in some of his work he is featured in a documentary about the Higgs on Netflix called Particle Fever.
14. Was there any Q&A on this?
15. So thats - the-the first part of 'v what I wanna talk about of-of the review is-is what-what the multiverse is...
16. He seems entirely unaware of just how fragmented  is his narrative flow.
17. jeez that was easy to follow!
    
18. Some of these young recruits seem lost (like 2nd row third from right with a stupid contempt on his face) are rethinking their choice of becoming a physicist as a profession.
19. hahahaha, you guys are so clearly, utterly lost, this is hilarious to watch
20. I wonder what life might look like on the other side of a black hole.
