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 have had a great life since HMC, I have worked on everything from military to law enforcement to environmental analysis in the Amazon to farming software. I am most proud of my work in remote sensing combined with knowledge-based earth / terrain modeling. This work has led me all over the US, Europe, and South America. The thread of satellite imagery combined with GIS data and then pumped through human rules of expertise has spanned almost all of my projects. I couldn't have done this at all without a strong background in physics.

I see physics as a "liberal" education in technology. It prepares one to understand much of modern technology, and in the sense that a liberal education prepares one for life but not for a specific role in life, physics gives one access to the world (should I say the universe?) in a general way that goes beyond preparation for research or an academic or industrial career. The physics curriculum develops curiosity, observation, reasoning, mathematical analysis, verbal and written discourse, etc., and these can be applied to writing, teaching, business, engineering, research, diplomacy - to any endeavor.

It turns out that Physics was a great intro for my particular job. I started as a digital electronics design engineer and the electronics part could be handled with the few courses HMC offered. The tough part was understanding the complex interrelationships of the functional blocks of the system. My physics background helped in this area although I did spend some intensive time reading electronics books. As time progressed, my job became more of an architectural endeavour and that was where physics really started to help: architecture involves understanding the big picture, not just the details of electronics but mechanical, thermal, software etc. At one time or another I have used almost every branch of technology. Only physics gives you enough understanding of theory to let you jump in and start swinging no matter where you land.
