Uh no, I can follow most derivatives pricing but Quantum Field Theory is several orders of magnitude more difficultWhen people bite the baits of random astrophysical fodders, like alien Drake equation, blackhole pics, gravity waves that are detected with billionth of a nanometers variations in length of a measuring rod. They are investing billions and billions onto these experiments just to make some sensations. Actually financial math has become far more complicated than astrophysical applications. Music, nature, life belong to the core interest of everybody`s Sherlock.
General relativity is based on the undergraduate level of Riemann Geometry and Newtonian laws, and the Special R is on Laurentz law which is also undergraduate level. But financial math now requires a mature math master to do, the stochastics and time series also the random process are a hell of deep water math. I love science too why do not start with some financial math? I think I am sticking to the topic of science: This is called the "financial science."
But physics is the most simple and basic of the sciences, which is why it has the most complex mathematics.
