Richard Courant,Fritz Johng sciences. The material has been used as a first-semester text for first-year undergraduates at the Niels Bohr Institute, which is part of the University of Copenhagen. Our way of presenting Newtonian mechanics is influenced by the writings of the late Max Born. Also, the Feynman Lectures on Physic水槽 发表于 2025-3-27 02:31:07
Richard Courant,Fritz Johnvements based on the experience gathered in the use of the first English edition of the book in the introductory course in physics at the University of Copenhagen. A chapter introducing nonlinear dynamics has been added. The purpose of this chapter is to provide supplementary reading for the student密切关系 发表于 2025-3-27 06:52:50

Richard Courant,Fritz Johns the Rubicon into differential calculus. The first, and crucial, step is to introduce first-order differential forms on a noncommutative space defined by a (complex) pre-C*-algebra .. We say crucial because, in most developed differential calculi (e.g., the usual de Rham complex of differential forIRK 发表于 2025-3-28 00:45:15

The Fundamental Ideas of the Integral and Differential Calculus,even in antiquity (culminating in the work of Archimedes), and with increasing frequency in the sixteenth and seventeenth centuries. However, the systematic development of calculus, started only in the seventeenth century, is usually credited to the two great pioneers of science, Newton and Leibnitz
