高速度、加速度,是新世纪发展的最大特点。进化论创始人之一华莱士曾统计19世纪的发明创造,竟然比以往各世纪的总和还要多,而20世纪又远远超过19世纪。我国科学家王大珩指出,现在平均每5分钟就有一项科学新发现,每3分钟物理学界就发现一种新的物质结构,每1分钟化学界就能找出一 High speed and acceleration are the major characteristics of the development in the new century. Wallace, one of the founders of evolution, once counted the inventions and inventions of the nineteenth century even more than the sum of centuries in the past, far exceeding that of the nineteenth century in the twentieth century. Wang Daheng, a Chinese scientist, points out that an average of every 5 minutes now has a new scientific discovery. Every 3 minutes, the physics community has discovered a new material structure that can be identified every minute by the chemical community
