Discussion Possible answer: He used to think that science would make good things, then he had doubts, because of the destruction of people caused by the atomic bomb. Find out the author's ideas on the value of science. ① Scientific knowledge enables us to do and make all kinds of things. ② Science provides us the intellectual enjoyment. ③ Science provides us very important experience with ignorance and doubt and uncertainty. Write a summary of the lecture When Richard Feynman was young, he thought the only use for science was to make good things for people. However, after he worked on the atomic bomb, he realized that science could also be used for evil. He wondered what the value of science really was and he decided on three values. The first value is that scientific knowledge enables us to do and make all kinds of things. The second is the intellectual enjoyment it can provide us with. And the third value is scientists' freedom to doubt. How do you understand Feynman’s words? This belief expresses a similar meaning to this unit's opening quote “The scientist is motivated primarily by curiosity and a desire for truth. “Only when scientists raise doubts can they open up the opportunity to explore the unknown, which is what leads to scientific achievements. Feynman further emphasizes this value when he says, “Permit us to question-to doubt-to not be sure.” He points out that scientists must always be allowed to question and doubt things, because he knows it is the key to how science is able to progress. 1. go off 2. with a bang 3. devote yourself to sb./sth. 4. let sb. down 5. turn over each new stone 6. take it for granted (that …) Vital expressions 1.
