Has anyone else completely fallen out of love with physics while studying it? I've been going through a year long Classical Mechanics class and we have been using David Morin's Intro to Classical Mechanics (the most misleading textbook title I've ever seen in school). This book has done nothing but frustrate me and destroy my love of a subject I used to think was incredibly interesting. Today, I spent four hours (I even took an hour break at one point hoping fresh eyes would help) on one of his "easy" one star problems. It was in chapter 11, on special relativity. The problem statement was as follows:
"A train of proper length L has clocks at the front and back. A photon is fired from the back of the train to the front. Working in the train frame, we can easily say that if the photon leaves the back of the train when the clock there reads zero, then it arrives at the front when the clock there reads L/c. Now, consider this setup in the ground frame, where the train travels by at speed v. Rederive the above result (that the difference in the readings of the two clocks is L/c) by working ONLY in the ground frame."
This wasn't even a HW problem, it was just me sitting down to do some review this morning and it spun into a huge long ordeal. I even already have the solution from the professor since it was an old HW problem. What upset me, and seems like a common problem I have with this book, is that in the end in order to get the solution he wants I had to violate something he presented earlier in the chapter. Here was my setup:
