    In 1948, Feynman showed Freeman Dyson his own proof of the Maxwell equations assuming only Newton's law of motion and the commutation relation between position and velocity of a nonrelativistic particle.

        The relativistic form of Maxwell's equations is so simple and beautiful. (Natural units are used.)pic.twitter.com/OwRymxz1rs

        It's beyond me Tamas, but I will go so far as to ask what the star operation represents.

        Absolutely not and you'd be kicked out of school. What does mechanics have to do with emag???

        I have two complaints about these formulae: 1> These deal with infinitesimal vector fields and we know that atoms are governed by quantum mechanics. 2> There is no way to accurately measure the divs and curls...try using a voltmeter??? come on, impossible.

        Humans invented Electric Fields and Magnetic Fields so they could more easily conceptualize Electric and Magnetic Forces. It turns out these Fields are real and they interact with each other to create light (among other things). That's the beauty of Maxwell's Eq's.

        @like_themineral can’t believe there was a time that I kind understood this! Not very, obviously. But still!

        In #GeometricAlgebra, this equating is easy simpler and more beautiful: (Nabla)F=J Where F is the electromagnetic field (a bivector of R{3,1}) the charge and current vector J.

        Maxwell's equations are soon to be featured on #Weeqly. Till then here's Newton's F=ma:https://twitter.com/TamasGorbe/status/950327383227355136 …

        Newton's 2nd law is an amazing discovery and one of the most fundamental equations in physics. It says that the net force (F) on an object equals its mass (m) times its acceleration (a). It has to be obeyed by (almost) everything that moves! [Wiki http://goo.gl/enGHft ] #Weeqly pic.twitter.com/7jf9oMpD2m
