• This is the eyeball technique. 
• We are going to whack the entire equation with an integral.

• Nobody else in the known universe uses 's' for the radial coordinate. 
• The preflight ... the spawn of Hell. 
• This is a classic example of separation of variables ... or is it? 
• First order may look like a sphere.

• An additional order might add a wobbly thing. 
• You take the big thing out of the thing. 
• You get something that is relatively pathological looking. 
• And this attacks E. 
• In condensed matter theory, you have HTSC - High Temperature Super Conductors.  In this class, you have HTCS - How To Calculate Stuff. 
• Why have 1 convenient symbol when you can have 3. It's much more confusing. 
• We have enough definitions that you might think this is a chemistry class. 
• This is the most simple problem in the universe. 
• Last time, we were casting our life, the universe, and everything we know in terms of free charges. 
• Remember the epsilons. It's like a Buddhist mantra. 
• There is a dielectric covering half of the world. There is a vacuum covering the other half of the world. 
• while doing an integral: This piece is gone! Oh blessed happiness! 
• The point fly has no idea where it is. 
• No more turgid algebra. 
• Today will be a fluffy class. 
• while discussing elliptic integrals- Mathematica gives you a symbol and then barfs out a big expression.
