[Elecraft] Maxwell's Equations.

[Herb Case]

How right you are, Kevin! I went through part of the Principia with my physics professor as an independent study. Newton's version of calculus is nearly impossible to understand and I wonder how many "natural philosphers" in his day could read it. Of course try introducing diff equations to the uninitiated and see what happens!!
