A History of Mathematics by Professor Jeong Wan-sang of Theoretical Physics

It is very important to meet the heroes of mathematics throughout history and learn about the mathematical problems they pondered and solved.
This is because it allows us to know what kind of mathematical research we should do in the future.
Volume 6 is the second volume on modern mathematicians, introducing in detail the mathematical achievements of heroes of mathematics from various eras, including Laplace, Legendre, Fourier, Poisson, Gauss, Cauchy, Abel, Jacobi, Hamilton, Grassmann, Sylvester, and Boole, in probability theory, calculus, celestial mechanics, heat conduction, number theory, complex functions, elliptic functions, quaternions, graph theory, vector spaces, matrices, and Boolean algebra, along with their history, at a middle school level.
