Einstein: His Life and Universe

by Walter Isaacson

They included more than 125 complex equations that he scribbled on the blackboard while speaking in German. As one student admitted to a reporter, “I sat in the balcony, but he talked right over my head anyway.”48 At a party following one of these lectures, Einstein uttered one of his most memorable and self-revealing quotes. Someone excitedly informed him that word had just arrived of a new set of experiments improving on the Michelson-Morley technique that seemed to show that the ether existed and the speed of light was variable. Einstein simply refused to accept it. He knew that his theory was correct. And so he calmly responded, “Subtle is the Lord, but malicious he is not.”* The mathematics professor Oswald Veblen, who was standing there, heard the remark and, when a new math building was built a decade later, asked Einstein for the right to carve the words on the stone mantel of the fireplace in the common room. Einstein happily sent back his approval and further explained to Veblen what he had meant: “Nature hides her secret because of her essential loftiness, but not by means of ruse.”
