Hi everyone! I have been stalking on this forum for a while now, and have finally gotten some courage up to post this. I am currently a physics undergraduate major at a state university. I am enjoying my studies and getting straight A's. I worked for many years in Silicon Valley as a test engineer and my first physics studies were in device physics at Bekerley which I found fascinating. During those days I decided that I HAD to learn physics. However, now that I am learning it, I am beginning to wonder what for... My plan is to go all the way through my PhD in physics. I had to start at the beginning because I needed all the math and science studies - so I have many years of study in front of me to obtain my PhD. I am thinking I might very well be in my mid 60's when I finish and I hope to find an actual job in physics, eventually. I love astronomy, particle physics, optics, and many other aspects of the field. My passion is the laboratory; gathering data, crunching numbers, tweaking experiments, rinse, repeat. So, here is my question; how do I choose a specialty - or even a minor? I thought about astronomy, but heard others say there is no work for a physicist with a minor in astronomy. Then I thought maybe physics with optics specialty would be fun - but search results showed no jobs. Everywhere I look, I see no jobs. Should I give up on a future at my age? What do you folks think?
