Quote by Richard Hamming
In science if you know what you are doing you should not be doing it. In engineering if you do not know what you are doing you should not be doing it. Of course, you seldom, if ever, see the pure state.
Summary
This quote highlights the contrasting approaches in science and engineering. It suggests that in science, where experimentation and exploration are key, having prior knowledge may hinder new discoveries. On the other hand, engineering requires a strong understanding of principles to successfully solve problems. The quote acknowledges that these ideal situations are rarely encountered, as the lines between the two disciplines often blur and combine in practice.
