Is there any branch of physics more difficult than quantum mechanics?

Question

Doing my Bachelors in Electrical Engineering. I thought Electromagnetics was tough and now I'm messing with Schrodinger's Equation. How much worse can it get?

Answer 1

I vote for superstring/M-brane theory. Quantum field theory would come in a close second.

Answer 2

Maybe quantum electrodynamics and quantum chromodynamics. Then again, Einstein's General Relativity equations are extremely complex.



Take a look at this link and the Fortran computer code for a single expression from just one of Einstein's equations:

And, to think Einstein did this before the age of computers.



Edit:



"Mathematically, General Relativity is built upon ten so-called "coupled hyperbolic-elliptic nonlinear partial differential equations" which take many pages to write down (and a deep breath just to say!). For a mathematician, the difficulties lie in the fact that the equations are nonlinear and coupled also and in their sheer number of terms.



After he published his famous paper in 1916, Einstein later conceded that the mathematical difficulties of his General Theory of Relativity were a "very serious" impediment to its further development. So serious, in fact, that it took nearly 75 years before the best minds in the field could come close to solving the equations stated by the theory. Now, high performance computers permit more accurate modeling of the distortions of space-time by massive objects, including black holes."

Answer 3

Well, I am a physicist, and I have to say it really depends on the person. I had a much harder time with orbital dynamics than with quantum mechanics, but many of my colleagues had a harder time with quantum. Quantum will probably be the hardest thing you have to learn as an EE though. Good luck!

Answer 4

I don't know that quantum mechanics is especially difficult. There is a set of mathematical techniques you need to master to do work in the area, and of course there are basic concepts you have to really understand. But that's true of every branch of every science.

Answer 5

Quantum mechanics and quantum physics are 2 factors of the comparable coin. it is a branch of theoretical physics. Maxwell Planck, Neil Bohr and Hassenberg with different scientists like Einstein of nineteenth century based this branch in the early final century. This branch deals with atomic structures, photons, and wave motions. the awareness of excellent judgment stepped forward in Quantum Physics is amazingly perplexing to comprehend. The deductions are in many circumstances empirical yet at circumstances contain complicated mathematical deductions, yet while utilized to many phenomenon like photograph-electrical energy, come out with passable rationalization. the fairly some conclusions of Quantum Physics like "gadgets do no longer exist except you notice them" are stunning. The conclusions that "some alerts could desire to be there which shuttle quicker than gentle and the "existence of gadgets except seen" weren't usual with the aid of Einstein. Many theories of quantum Physics are philosophical and a few of them are nonetheless unacceptable to lots of scientists. it is a mysterious technological know-how. you are able to examine extra approximately introductory literature with the aid of google seek with the aid of in basic terms typing 'Quantum Physics'........

Answer 6

Well there's quantum field theory, much much worse.

Answer 7

Nuclear bomb science math difficulty is proportional to the mass destruction

Answer 8

fluid dynamics

Answer 9

rocket science. it is very complicated.
