1 you still need a certain mathematical foundation to study finance. Many Nobel Prize winners related to finance have a deep mathematical foundation.

2. Mathematics, physics and engineering methods are widely used in finance, and the tools to explain financial thoughts have developed from daily language to mathematical language, which has theoretical spirit and abstraction and is the progress of financial discipline. When I started to set foot in financial theory, I applied physics and applied mathematics to the pinnacle of financial model, such as using mathematical tools such as difference, partial differential equation and random integral to describe the stock trend and yield curve. When I was a Ph.D. student in finance, one of my classmates was Italian. His major is physics, so I chose finance because I expected it to become physics in the late 20th century. 1 1 years later, things are not as he expected. Physics and mathematics did not dominate finance, and a perfect financial model did not appear. After experiencing the enthusiasm for physics and mathematics, finance has returned to the basis of fundamental analysis.
