The course was given by a professor from chemistry department. This was the 3rd time I’m taking this course, I had not attended any of the lectures or exams so far. My high-school chemistry teacher made me hate the subject. Anyway, when I arrived to school, it was “quite” late, the lecture was going to be over in 15 min. Nevertheless, I wanted to get in, so I slowly sneaked in and looked around for a free seat. As I made way through, I was suddenly stunned by teacher’s words:

How and why it works was a mystery to me, but I loved the idea of having a minimal principle anyways. Since it was like nothing I had known before, I thought it must about some physics I didn’t know by then, maybe quantum mechanics.
