Schwinger correction, Electron Magnetic Moment
----------------------------------------------

Reading: 

   A. Zee: "Electron Magnetic Moment",
   excerpt on ChaosBook.org/library  (click on Field Theory link)


Exercises: 

	1. evaluate
	   gamma^\mu a gamma_\mu 
	   gamma^\mu a b gamma_\mu 
	   gamma^\mu a b c gamma_\mu 
	   where a, b, c are "slash" products of 4-vectors 
	   a, b, c dotted with gamma matrices

	2. go step-by-step through the Zee derivation of the
	   \alpha/2\pi correction Eq. (16)

Bonus points: 

	3. derive Zee Eq. (10) on p. 180

	4. evaluate the 4-momentum integral leading
           to Zee Eq. (10) on p. 180
