When he states that something is impossible, he is very probably wrong. Our future discoveries must be looked for in the sixth place of decimals. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of twentieth-century science to the human intellect. A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it. Science for me is very close to art.
Scientific discovery is an irrational act.
One could not be a successful scientist without realizing that, in contrast to the popular conception supported by newspapers and mothers of scientists, a goodly number of scientists are not only narrow-minded and dull, but also just stupid. A man with a new idea is a crank until he succeeds. If your ideas are that good, you'll have to ram them down people's throats.
