Richard P. Feynman Method Quotations

I think equation guessing might be the best method to proceed to obtain the laws for the part of physics which is presently unknown. Yet, when I was much younger, I tried this equation guessing, and I have seen many students try this, but it is very easy to go off in wildly incorrect and impossible directions.

When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.

First figure out why you want the students to learn the subject and what you want them to know, and the method will result more or less by common sense.

Observation, reason, and experiment make up what we call the scientific method.
