The Art of Doing Physics in Dirac’s Way

  • F. Rohrlich
Part of the Studies in the Natural Sciences book series (SNS, volume 20)


It is a great pleasure for me to have the opportunity to contribute to this volume in recognition of Professor Paul A.M. Dirac, at the occasion of his eightieth year. While I have not had the privilege to be among his students, I have been a student of his books and papers all my life as a physicist. I first encountered his Principles of Quantum Mechanics 1 as a graduate student at Harvard. (Before that time I had studied engineering and had not been exposed to a course in quantum mechanics.) This remarkable book made a deep impression on me. Its elegant style and its direct and straight reasoning will forever remain an example of exposition at its best.
