The mathematician who made the quote I mentioned said that quantum mechanics was just <some branch of mathematics that I’ve forgotten> in dimension 1. I don’t know what quantumn field theory is. If it is a branch of physics then it’s not the theory the mathematician I referred to mentioned. Some mathematicians view mathematics as superior to physics and are dismissive about physics. They tend to believe that since they mastered mathematics then learning physics is easy.
