Witten and that middle eastern fella with long hair whose name I can't recall right now

He came to our university a few years ago, pretty cool guy

>>12280433

>>12280629
Hawking is a meme

>>12280556
>Witten
That's a mathematician.
>>12280629
>Hawking
That's an astronomer

my votes are
1) Steven Weinberg
2) Gerard ‘t Hooft
3) Edward Witten
4) Cumrun Vafa
5) Roger Penrose

>>12280556
you mean Nima Arkani-Hamed? he’s cool but i haven’t seen his work enjoy much success. ADD basically got debunked and his amplituhedron/polytope stuff doesn’t seem to really have materialized yet

>>12280433
>contemporary physicist
>Penrose
his most notable work was done in the 70's.
there's plenty of other people who did work around the same time and then died.
just because he still happens to be alive(and good for him) doesn't make him a great contemporary physicist(emphasis on contemporary).

Sean Carroll, obviously

>t. the ghost of Steven Gubser

Eric Weinstein, didn't you see the JRE episode where he BTFO'd Einstein and Dirac?

>>12280746
The man was an astrophysicist

>>12280779
Yeah, you're right. I'm new to physics so I'm not familiar with all the big names.

Also, what do you guys think of string theory? Cutting edge or unfalsifiable abstraction?

>>12280828
>unfalsifiable abstraction
no, it's clearly falsifiable. and almost certainly is false. Absolutely zero empirical basis.

>>12280819
That's an unfalsifiable claim

>>12280872
Then what went wrong for it to be promoted so heavily?

>>12280886
Theoretical physics reached a dead-end, and modern academic set in, where it's more what institution you work at and how elegant appearing your papers are, rather than is that shit actually true.

The future members of secret academia and me

All of these are mathematicians, not physicists.

is that what sabine told you?

The interesting thing about this guy is that he is actively at war with mainstream cosmology. Is he deranged, or is everyone else? Only time can tell.

It was Dimebag Darryl

>>12281044
my understanding was that Penrose's ideas on cosmology ("conformal cyclic cosmology") aren't directly at odds with anything in the LambdaCDM model. his ideas, as far as i can tell, are more just of an "interpretation" of cosmology and the implications of the very late future of a cold heat death. correct me if i'm wrong, though.

if you want somebody who is at war with mainstream cosmology, look at a fellow Nobel winner: Bob Laughlin

RIP Dime. Guitarist. Philosopher. Physicist. Pioneer. Legend.

redpill me on this guy. i apparently missed out

>>12281309
Awesome metal guitarist who founded the band Pantera with his brother who played drums.
Eventually they left the band over a falling out with the lead singer.
Started another band, Damage Plan.
Ultimately was shot to death on stage by a scziophrenic fan. Buried with one of Van Halen's guitars in the casket.

Brainlets who lick Woit's dick & Sabine's pussy detected. Keep seething, faggots.

>>12280433
In the fundamental area, Witten (quantity) and Maldacena (quality). I don't know about applied fields.

Guarantee its a list you’ve never heard of in USA, China, Russia working on things you’ve never imagined with means beyond any conceived. All hushity hush and toppity secret classidy classified blackity black sited of course.

>>12280828
String theory is the extremely mainstream theory in the fundamental area such as high-energy physics and cosmology. Don't listen the stupid fag like >>12280872. This board is just a piece of brain-dead shit, those who can't even understand high-school level math. This is why modern society is fucking cringe. Stupid people who drop out the single-variable calculus class talk about string theory. KEK

>This board is just a piece of brain-dead shit, those who can't even understand high-school level math.

ahem... you’re here too. but oh i suppose you’re excluded with your big big brain

>>12281959
At least I don't contempt what I don't understand well. Look at this board. Brainlet fags always keep pooping shits like 'hurr durr string theory bad! muh experiment!'. This fucktards have nothing but just the huge ego and arrogance.

>>12280433
too bad the guy has gone batshit crazy trying to explain consciousness with quantum gravity effects in microtubules

Nah, they are bonkers theoretically

>if you want somebody who is at war with mainstream cosmology, look at a fellow Nobel winner: Bob Laughlin
what an awkward video, especially to bits with only the students.
watching gross seethe anytime laughlin says anything is surprisingly satisfying though

>>12281999
I will be very sad when he’s gone. He’s got the right spirit, something just makes you respect him.

>>12281966
So can it be experimentally tested?

>>12282573
in principle? sure
in reality limited by our engineering capacity? no

>>12282711
Will we ever have the engineering capacity to test it?

>>12280433
Lee Smolin.

>>12285060
>Lee Smolin (/ˈsmoʊlJn/; born June 6, 1955) is an American theoretical physicist, a faculty member at the Perimeter Institute for Theoretical Physics, an adjunct professor of physics at the University of Waterloo and a member of the graduate faculty of the philosophy department at the University of Toronto. Smolin's 2006 book The Trouble with Physics criticized string theory as a viable scientific theory.
>The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next is a 2006 book by the theoretical physicist Lee Smolin about the problems with string theory. The book strongly criticizes string theory and its prominence in contemporary theoretical physics, on the grounds that string theory has yet to come up with a single prediction that can be verified using any technology that is likely to be feasible within our lifetimes.
I haven't seen any defender of string theory sufficiently respond to these pointed out flaws so I'm inclined to side with the anti-string theorists.

>>12285092
I'm also a huge fan of his theory that the our universe is inside a black hole, and the pre-big-bang matter was the formation of a singularity that pushes so hard inwards it expands space, time, gravity, and best of all, that expansion causing particles to form by virtue of fighting against itself in n dimensions

>>12285092
> I haven't seen any defender of string theory sufficiently respond to these pointed out flaws
which flaws?

smolin is a hack, also he dedicated a passage in that book to praise epstein, also he has ruined Jacob Barnett’s career by keeping him on to year 9 as his supervisor. so as far as i know he is a terrible physicist, like basically the worst anyone could name

>>12285103
>which flaws
The same accusation that's always thrown out when string theory comes up: that it can't be tested. I've found no real counter to this.

Idk but i like listening to Frank the most:

don't agree with him on SUSY, but man his voice is as smooth as a top notch vodka

Mike McCulloch. Doing science that could actually revolutionize some fields of engineering.

>>12280433

String Theory is basically something like Weyl symmetry was back in the day. So beautiful it forces you to think it must be correct, but it is ultimately punishingly wrong and universe doesn't give a fuck about beauty in math.
