I forgot to tell everyone that I am a student at a normal university, currently in my senior year. According to my plan, I have already started my internship at a high school. Therefore, updates might not be very frequent over these two months, and my replies may not be timely. I hope everyone understands.
During these two months, I am spending some time every day working on the exercises in “Quantum Mechanics and Path Integrals” and organizing them to share with you. This is currently version V0.1, which for now only contains solutions to most of the exercises in Chapters 2 and 3.
By the way, I used to be quite averse to books that are collections of exercise solutions. However, Feynman’s book is different. The exercises inside are not traditional routine imitation exercises, let alone simple homework problems; they are truly meaningful thought-provoking questions. Every exercise implies a deeper understanding of the original work and represents a significant challenge to oneself. Therefore, I believe that thinking through these exercises and sharing the insights gained with readers is very meaningful.
In the document, I have tried my best to provide the most concise solution processes possible. Of course, it is difficult to achieve perfection. Therefore, if there are any errors or improprieties in the solutions, I hope readers will not hesitate to point them out.
