I finally bought the Feynman Lectures on Physics, something I wanted to do for a very long time. Ever since reading You’re Surely Joking Mr. Feynman. After watching some of his interviews on YouTube and going through a few chapters online, I realized there’s something special about how Feynman explains things. He doesn’t just teach formulas — he teaches understanding. Once you grasp that, you realize what true understanding is. Here are a few quotes from the introduction to the New Millennium edition:

It was like going to church. The lectures were a transformational experience, the experience of a lifetime, probably the most important thing I got from Caltech. I was a biology major but Feynman’s lectures stand out as a high point in my undergraduate experience … though I must admit I couldn’t do the homework at the time and I hardly turned any of it in. I was among the least promising of students in this course, and I never missed a lecture. … I remember and can still feel Feynman’s joy of discovery. … His lectures had an … emotional impact that was probably lost in the printed Lectures.

The book is beautiful. I don’t choose books solely on looks, but when there are different options, it’s better to go for the one you like. I’ve noticed that this works for anything — if I like something that’s part of an activity, I’m more likely to engage with it. So, in that sense, it is rational to choose a book by its cover. One sad thing is the lettering from the original edition has been lost in the New Millennium version:

Almost all other popular physics books look very average. Compare another popular textbook with the austere design of Feynman’s lectures:

My plan is to work through all three volumes over the winter and solve all the exercises from the companion workbook. I will buy a refresher for math once I hit a wall. There are a few books I have in mind: Spivak’s Calculus and The Princeton Companion to Applied Mathematics. Both are as beautifully designed as Feynman’s lectures.
