And when it came to physics, we were learning Newton's laws. And there was this professor who was explaining how you only need to know the initial velocity and an angle of a projectile. And the rest of it was given by a simple physics law of gravitation. So you could derive everything. You could figure out everything on your own. You didn't have to remember things. And that was a transitional day for me. In the morning, I had this botany class where the teacher told me you had to remember 4,000 Latin words. And in the afternoon, the professor told me, you don't have to remember anything. You just had to remember one law of physics and play with it. And that was the way I got attracted to physics.
