E= (p2c2 +m2c4)1/2 E = −A˙ /c−∇ϕ This list is not, of course, complete; but if you are familiar with these equations, you probably know enough about quantum mechanics, classical mechanics, special relativity, and electromagnetism to tackle the material in this book. Quantum field theory has a reputation as a subject that is hard to learn.
