德国波特教授于1954年与麦克思·蓬因发展了测量宇宙线用的符合方法而获得诺贝尔奖金,于1957年2月逝世。本文是他去世前几个星期写的一篇文章,里面有许多切身经验之谈,虽然他的观点和方法我们不完全同意,但他的经验有些对我们有用处,因此译出来供大家参考,希望大家用批判的态度对待之。 In 1954, Professor Porter won the Nobel Prize in 1954 with the development of a method suitable for measuring cosmic rays by Max Pengne, and died in February 1957. This article is an essay written a few weeks before his death with many personal conversations. Although his views and methods are not entirely agreed upon, his experience is somewhat useful to us and is therefore translated out for your reference. I hope everyone will treat it with a critical attitude.
