I started out at the University of Saskatchewan in biochemistry. For that major, physics was a prerequisite. Although I had taken physics in high school, it wasn’t my favorite subject. I liked biology and chemistry, but the reading in those courses became overwhelming. Physics, on the other hand, included lab work. We learn theories, and then in the lab, we see those theories in action. That helped me understand the material better, and I decided to switch my major to physics.
