Yes.

Who cares, dunno, who cares, who cares, just because, who knows.
I hope my responses were enlightening.

Well that was a silly reply. Countersage.

>>4572246
Which of the twp?

I do. Okay, then I guess not. I do. I do. Okay. True.

I'm studying physics.The institute I am at is strong in string theory, quantum gravity and quantum information. I'm focusing on string theory and quantum field theory, because it is interesting and contains a lot of very nice ideas. And I'm probably not gonna accomplish all that much, as I have come to realize that most people doing string theory are extremely bright and talented.

I highly doubt that.

Loop quantum gravity fan here.

Why do you like it?
How good do you know it?

Bulldadash, matter is clearly made of tiny little strings.
But seriously, without string theory there would be no higgs boson.

I'm actually taking a course on LQG right now, and the more I learn, the more I realise how "stupid" the theory is. The way I understand it, they discretize spacetime and come up with some clever way to discretize the action. And then they try to show that the theory constructed this way gives a sensible classical limit, something nobody has shown thus far. There doesn't seem to be anything deeper happening, none of the magic you find when you study string theory, and furthermore they have little to no idea how matter fits in with the theory. If a theory doesn't have any matter, can it really be called a theory of gravity at all?

Studying Theoretical Physics and Applied Maths here.

Theory department does a lot of work on condensed matter systems and nanotechnology.

Applied Maths research focuses on Fluid dynamics, with links to drug delivery systems et. al..

3rd of 4 years.

Not really specialising in anything until next year, but I'd like to do something which involves non-linear systems theory or perhaps gauge theories.

chose it because the course looked fucking interesting and it really is. My course has a big focus on getting a strong foundation in the mathematics underlying the physics. Makes us far better at understanding what the maths means for the physics.

I used to think I'd do something big, but now I'm a little more pragmatic. I'd like to work in nuclear energy and promote positive attitudes towards the industry. that's where the money's at.

I agree that string theory seems fuller and nicer. And the matter-problem is of course a terrible feature.
Nevertheless, there are some intruiging aspects to Loop Quantum Gravity, namely how time is treated. I have a massive problem with time and the Wheeler–DeWitt equation is a nice way of getting rid of it, in a way.
String theory is not too different from other QFTs, imho, but since it actually talks about bosons or fermions, it's much much closer to produce result - and I also have no idea how LQG would relate to Gauge-Gravity duality. It probably doesn't.

like what?

>>4577842
I dunno, that doesn't sound any more 'stupid' than going "hey I wonder what happens if we take world sheets instead of world lines? We get d= 10? Okie dokie, we'll just throw in a Calabi-Yau manifold of d=6, compactify that and say that shit's all good now". It just sounds like there isn't as much progress in LQG as in ST, which makes sense considering there's a lot less people working on it.

Math student here. First year.
My institute is very famous for its statistics course.
I love number theory and algebraic geometry.
Part of that love came from Alexander Grothendieck's life. :)
