So what do I think about a physics education some 30+ years after graduation? Would I do it all over again? There's absolutely no question in my mind. For anyone entering virtually any of the engineering or science disciplines, with maybe the exception of organic chemistry, an undergraduate physics education is invaluable. I went on to the Department of Aeronautics and Astronautics at the Stanford School of Engineering for my Ph.D., and my HMC physics degree was a major advantage in practically every class I took and in my thesis research. In addition, in my years as a technical contributor, having the breadth and depth that a physics degree provides made me much more versatile than my colleagues who studied some branch of engineering. I was able to apply basic concepts from E and M, dynamics, optics, and even basic nuclear physics / relativity theory / quantum mechanics to solving problems and inventing new techniques. The ability to understand physical phenomena and apply basic principals to analysis and problem solving is directly related to the solid foundation that I got as a physics major. The colleague with whom I had my most successful collaboration, by the way, has a Ph.D. in physics (with engineering subjects, from the Sorbonne) and my former boss has a degree in Engineering Physics from Cornell---just indications of how a physics degree is a key building block to a successful technical career.

Physics majors can certainly go on to do all kinds of strange things, even public policy and international affairs:

Physics training has been an invaluable aid throughout my career despite my grade in quantum mechanics. : >

I'm currently finishing my PhD in Biology here at UCSD. This was a big change from physics and I am not directly doing much physics related research. However, I think my physics training was very important. I learned how to be a clear, critical, scientific thinker which has served me well here. Having a physics background in no way hindered my applications to biology graduate schools. I think most schools considered it an advantage. The field of biology is becoming much more analytical and the perspective I have with a physics background is quite useful. Now that I am looking for a job, I think having a background in both physics and biology will help a lot.

I was in fact fortunate enough to land an academic position... especially a relatively enjoyable one. Tenure is nice, too! My education at Mudd was a thorough preparation for graduate study... that was no problem.
