Feynman’s freshman physics lectures remain treasured by experts decades later

Evidence

One of the most important sources for this book is not listed in the bibliography: Lectures on Physics by R. P. Feynman, R. B. Leighton, and M. Sands (Addison-Wesley, Boston, 1964). Written as a freshman textbook more than 50 years ago, it has been read with equal relish ever since by the interested public, students, PhD candidates, and professors. … The mathematical level here is well below Feynman’s Lectures, but I hope the level of enthusiasm for the subject and the infusion of intuition is worthy of his example. — Eric J. Heller, Why You Hear What You Hear- An…, 35

Categorization

• XREF: Connects to the common theme in physics education that intuitive, enthusiastic exposition outranks mathematical rigor in teaching; Feynman’s Lectures is the canonical exemplar.
• CANDY: A nice coffee-break fact: a textbook written for freshmen in 1964 is still read with relish by professors and PhD candidates.
