When I was about 18, I went to university to study Electrical Engineering. It was quite astonishing to learn that everything from light to radio to cosmic radiation could be described by those four elegant mathematical equations, written down in 1865 by James Clerk Maxwell.

It still amazes me how exactly mathematics can describe the physical phenomena of electric and magnetic fields, when we don't really understand what those fields really are...
