Postulate: Lagrangian submanifolds in symplectic geometry have physical meaning.

Lol that's not a postulate, it's a BS PR news release.

Postulate: Lagrangian submanifolds in symplectic geometry have physical meaning.

Symplectic geometry was literally created from studying classical mechanics, most things in the subject have physical meaning.

So it’s perfectly sensible for physicists to study Fukaya categories, eg.

Maybe instead of asking the same retarded question every week, you should go learn quantum field theory and string theory and realize why your question is retarded.

That's hilarious that you still refuse to provide any principles, postulates, or equations. Are u Michio Kaku? lol

Even asking the question implies you do not understand quantum field theory, which means attempting to explain anything about string theory to you is futile.

I’m a phd over here. I would like to know: what are string theory’s principles, postulates, predictions, and equations?

Yes somebody please just share string theory’s principles, postulates, predictions, and equations.

If you asking sincerely, you should first specify what do yo already know (what areas of math you work in? What do you know from physics: classical mechanics, quantum mechanics, electrodynamics, statistical physics, quantum mechanics, quantum field theory, gauge theory, conformal field theory) and whar exactly are you interested in (firet of all, if you are interrsted in string theory as the ultimate theory of everyrhing, as in toy model to develop sone new computational methods, or in various areas of stringy math, because these are three very different directions).

The short universal answer is the functional integral with Polyakov or Nambu-Goto action, which is at the same time principle, equation and source of predictions. Everything else is an attemp to make sense of it.

So the functional integral with Polyakov or Nambu-Goto action makes no sense and all of string theory is devoted to trying to make sense of the nonsensical?

Yous should answer the questions first.

This is like saying everything about quantum field theory is an attempt to make sense of the path integral for a free particle.

Nope, the string path integral is not about free strings only. It allows to compute all string amplitudes in perturbatuon theory. This, by the way, one of simple predicrions of string theory, together wirh very peculiar spectrum of states (too bad both can be distinguished from the corresponding effective QFT at too high energies to actualy verify the predictions).

The QFT counterpart of that is the worldline formalism, not

Both, of coursez fail in highly non-perturbative regimes. But making the theory work non-perturbatively is part of making sense of it.

So basically string theory has no principles, postulates, predictions, nor equations.
