As a physics major, I think about various physics things a lot. Right now I am attempting to wrap my head around Quantum Mechanics (just the "simple" stuff right now). Thinking about the fact that a particle may or may not really be where I think it is supposed to be really challenges the imagination. Even the great minds of the 20th century that created all of quantum mechanics could not agree on the actual foundations of the interpretation. Albert Einstein was famously quoted "God does not play dice" when talking about the probabilistic interpretation of quantum mechanics that is now accepted as the norm.
Astrophysics is another fascinating subsection of physics. Every day new discoveries are made. So far, astrophysicists have determined what happened less than a second after the big bang, but they are still working on the rest of the way back to the actual big bang. Additionally, new discoveries are giving us a better understanding of the fundamentals of the universe. Through astrophysics, various predictions about other theories have proven to be true, e.g. the discovery of the neutrino. Astrophysics also draws together many other parts of physics for the explanation of each phenomenon.
Through my studies of computer science I have learned lots of cool things about how computers work and are designed. Additionally, I have learned lots of programming techniques (mostly through trial and error on homework assignments). Ever since I was very little I have been fascinated by computers and have loved using computers. Recently, I have become enamored with the interaction of the software with the hardware (which, by the way, is where physics meets computer science). As I have learned more about programming and hardware interaction, I respect the original designers of the computers and also the programmers of the many programs that I use every day.
Ok, so maybe this isn't exactly an academic interest for me, but it still deserves to be mentioned here. I have taken a course in Lighting Design; however, most of the things taught in that particular course were subjects I had already learned on my own. The class was a lot of fun nonetheless. When I do have free time, I love to work on technical work for theatrical productions. First and foremost I am a lighting designer, but I love to help build sets and work on sound equipment as well.
