Often, I'm asked by people major in physics, a horrific choice for many. So, I cooked up the main reasons, though some by seem a little absurd, though correct for some. You really want to understand physical reality and understand how the models explain it. You have problems with the physical world compared with the spiritual world. That is, your beliefs are challenged. You absolutely love physics and feel there is no other subject for you. You ultimately want to study the origins of the universe and wish to understand all the theories extant. You get a scholarship in physics. Your parents give you three choices of what to major in, physics, physics, and physics. You do physics because you want others to think you’re smart. Finally, you doubt your intelligence and want to take on a difficult subject simply to master it, and thereby prove to yourself your intelligence. P.S. I was a physics major, but changed to math in grad school. I never felt I understood physics.
