Hello everybody! I am going to be heading to university in the spring and I am having a lot of trouble deciding on my potential major. I plan on attempting to experience research in both areas while I'm in college, but not knowing exactly what I want to do is killing me. Since the beginning of the year, I have gone though Kleppner and Kolenkow's Classical Mechanics and I am about to finish Calculus by Spivak. I chose these books to get a real look at my potential future and the rigor involved in both areas. After working through K&K I was dead set on physics. Their way of introducing newtonian mechanics blew my mind and I enjoyed every painstaking minute of working through the problems. The beauty of their explanations never ceased to amaze and excite me. I am highly looking forward to exploring the world of electrodynamics. I never understood just how amazing Einstein was until reading working through some initial problems. However, I wanted to also experience pure math because a lot of what I enjoy about physics is the mathematical aspect. I was hoping attempting Spivak would solidify my decision to stick with physics. It didn't. I have been thoroughly enjoying the rigor and complete understanding that comes from proving theorems. So, as you know by now, I remain undecided. I know this will be a completely personal decision I will eventually have to make, but I would enjoy hearing from the many brilliant people on this forum. TLDR What was you initial inspiration or reason for exploring the option? Why did you choose Physics/Math? (or engineering, biology, etc. special preference on the former) What aspects of the subject led you and keep you in the subject? Where did you get or continue to get your inspiration? Thanks everybody, I look forward to seeing your responses.
