一五十年前,五月的一个下午,剑桥大学评议会坐满了教师和学生,以及不少嘉宾,他们都是来出席剑桥大学一年一度的里德演讲的。一个身材高大的人走向讲台,开始了他一个多小时的演讲,讲题是《两种文化与科学革命》。 Fifty years ago, in the afternoon of May, the University of Cambridge council filled with teachers and students, as well as many distinguished guests, who came to attend the annual Reid speech at Cambridge University. A tall man walked to the podium and began his more than one-hour speech entitled “Two Cultural and Scientific Revolutions.”
