近几十年来,人们对于微观世界的认识正在不断地深入。人们知道了原子的结构。在研究原子核的过程中,人们发现了中子、质子,中微子、阳电子、各种介子、超子等基本粒子,知道了它们的特性和转变。在另一方面,人们已经能够从原子核中摄取大量的能量,制造各种各样的同位素,为人类的幸福服务。人们对于自然界的认识,所以能达到今天这样的地步,是经过许许多多人的劳动的结果。这当中,人们也经历了曲折的漫长的途程。“物质之谜”这本书,为我们概括地叙述人类认识微观世界的历史。古代的哲学家认为宇宙间的一切东西是由土、水、空气、火四种“原质”和热、冷、湿、干四种“元行”按各种比率互相混合而成的。人们认为金也可以由“不贵”的东西炼
In recent decades, people’s understanding of the microscopic world is constantly deepening. People know the structure of atoms. In the process of studying atomic nuclei, people discovered neutrons, protons, neutrinos, positrons, various mesons, superons and other elementary particles, and know their characteristics and transformations. On the other hand, people have been able to take a lot of energy from the atomic nucleus, create a variety of isotopes, and serve human happiness. People’s understanding of the natural world, so it is possible to reach today’s level, is the result of the work of many people. Among them, people have also experienced a long and winding journey. The book “Material Mysteries” gives us an overview of the history of mankind’s understanding of the microcosm. Ancient philosophers believed that everything in the universe was made up of soil, water, air, and fire, and four kinds of “primitives”, hot, cold, wet, and dry. People think that gold can also be made from “not expensive” things.
