I was curious about the famous Maxwell's equations, and decided, perhaps foolishly, to learn them myself. I know basic Electricity and Magnetics with Calculus, so I figured it was the next logical step. I understood the integral forms of Maxwell's equations, but I got completely lost when I saw the upside down deltas in the differential forms of the equations. Could someone tell me what they stand for and/or what mathematical operation they entail?(adsbygoogle = window.adsbygoogle || []).push({});
