Mathematics and Economy 1838, Cournot, a student of Laplace and Poisson's mathematics department, started his academic career by studying probability theory, and suddenly published an economic book entitled "Recherches sur les principles Math 6 Matiques de Lath 60 Riedes Richess". This book is full of mathematical symbols. For example, if the market demand is D and the market price is P, then the demand as a function of price can be recorded as d=f(P). For college students majoring in economics, this is naturally a very common thing. But in the Cournot era, economists simply could not tolerate this kind of "nonsense". Their opposition forced Cournot to remain silent about economics for 25 years. 1863 Cournot rewrote his works in popular language. The "mathematics" and "research" in the title of the book have been avoided, and they have become "the principles of wealth theory". But the mathematician's rigorous thinking method still made this book encounter a cold shoulder. Cournot's historical position was not fully affirmed until 80 years after his death. As de Blau said in his 1983 Nobel Prize in Economics:

"If you want to choose a symbol of the birth of mathematical economics.

On the day of sex, our series will be selected with a rare consensus.

1838, ... Cournot was the first person to establish and clarify the economic situation.

For example, the founder of mathematical model. "
