From the list on the philosophy of physics.
Who am I?
My undergraduate physics textbook asked, “What is an electric field? Is it something real, or is it merely a name for a factor in an equation which has to be multiplied by something else to give the numerical value of the force we measure in an experiment?” Here, I thought, is a good question! But the textbook said that since electromagnetic theory “works, it doesn’t make any difference" what an electric field is! Then it said, "That is not a frivolous answer, but a serious one.” I felt ashamed. But my physics teacher helpfully suggested that I “speak to the philosophers.” I am very pleased that I decided to become one!
Marc's book list on the philosophy of physics
Why did Marc love this book?
This book has it all. It describes Einstein’s own fascinating path to both the special and the general theories of relativity. It explains why relativity theory involved such revolutionary steps and yet remains continuous with 19th-century physics. It examines (and, in some cases, debunks!) the philosophical morals (about spacetime and about the logic of scientific reasoning) that have sometimes been drawn from relativity theory. And it looks closely at the reasons for Einstein’s critical attitude toward quantum mechanics. Norton is not only one of the world’s leading Einstein experts, but also a superb writer and teacher.
