Physicists all over the world, back in 1895, were pretty much agreed that the great work of physics had all been done. Some of them mourned publicly that no discoveries of truly major importance were likely to be made in the future. But then they did not know that a Professor Roentgen, working alone in a modest laboratory in Germany, had begun a series of experiments with a crude induction coil, a pear-shaped bulb from which the air had been removed, and a sheet of paper painted with certain metallic salts. And professor Roentgen did not know that his work was destined to reveal a force of nature—never before suspected—that would almost overnight revolutionize medicine and technology, and become an instrument for deeper probing of the structure of matter.
选项
答案
1895年,世界上的物理学家普遍认为所有有关物理的伟大研究都已经完成了,他们中的有些人甚至公开宣称将来不可能再出现真正有意义的重大发现了。但是,那时他们还不知道,在德国一间小小的实验室里,一位叫做伦琴的教授已经开始了对粗略电磁感应线圈,一个被抽走空气的灯泡以及一张涂抹了某种金属盐的纸张进行的一系列实验。伦琴教授不知道他的工作注定会揭示自然的某种力量——而这种力量是人们从未料想到的,它最终将几乎一夜间引起医学和技术领域的变革,成为一种深入探测物质内部结构的工具。
