It is a fundamental theory that has revolutionized our understanding of the universe and has led to the development of technologies that have transformed our daily lives. In this article, we will explore the fascinating world of quantum mechanics, its key concepts, and its profound implications for our understanding of reality.

This paper discuss the relation between Taylor's formula and partial differential equation. Taylor formula iteration method can resolve partial differential equation u(x,t) be expanded at t=0 or t=1 by Taylor formula. Coefficient of Taylor formula u_t(x,0), u_tt(x,0). . . can be expressed by partial differential equation. The method can solve nonlinear differential equation. Generalized Taylor's formula can solve fractional partial differential equation. The method is very important way that resolving partial differential equation. This article refers to the literature. Taylor formula iteration method belongs to logical thinking.
