我记得最清楚的是,当我提出一个自认为有道理的设想时,爱因斯坦并不与我争辩,而只是说,“啊,多丑!”。只要觉得一个方程是丑的,他就对之完全失去兴趣,并且不能理解为什么还会有人愿在上面花那么多的时间。他深信,美是探求理论物理学中重要结果的一个指导原则。 What is most clear to me, I remember, was that Einstein did not argue with me when I made a hypothesis that I considered justified. I just said, “Oh, ugly!” When he thinks of an equation as ugly, he completely loses interest in it and can not understand why there are still people who will spend so much time on it. He is convinced that the United States is a guiding principle for exploring important results in theoretical physics.
