The Collected Works of Einstein Title: The Collected Works of Einstein Author: Einstein Translation: Xu, Fan Dainian Compilation Topic Keywords: The original text of popular science is naturally the practical embodiment of the simplest mathematical concept imaginable. I firmly believe that we can use the structure of pure mathematics to discover concepts and the laws that relate these concepts. These concepts and laws are the key to understanding natural phenomena. Experience can prompt suitable mathematical concepts, but mathematical concepts can't be deduced from experience anyway. Of course, experience is always the only criterion for the physical utility of architecture. But the principle of this creation exists in mathematics. This book is edited by Stachel *, director of the Einstein Research Center of Boston University, and has a detailed introduction. The book brings together the five classic papers mentioned above, including Einstein's doctoral thesis, the thesis on Brownian motion, two papers on special relativity and the thesis on quantum hypothesis, and makes a background description for each paper, with the editor's note and the preface written by roger penrose, a famous mathematician and theoretical physicist. Therefore, this book not only has high literature value, but also has a more profound enlightening effect on understanding Einstein's original thought in the early 20th century and how it changed the face of physics. * Note: Stachel, American physicist and philosopher of science. From 65438 to 0958, he received a doctorate in physics from Stevens Institute of Technology. From 65438 to 0964, he retired as a professor of physics at Boston University and director of the Einstein Research Center, and was the first editor-in-chief of the Collected Works of Albert Einstein.
