In the text Griffiths also touches on two additional points:

- "A solution to Laplace's equation has the property that the average value over a spherical surface is equal to the value at the center of the sphere"

- A uniqueness theorem

A first question that came to my mind: why do we assume that separation of variables works? How can we assume that the solution is of the form [itex]f(x)g(y)[/itex]? What if it had an expression like [itex]x^y[/itex]?
