    I don't get it:

    AND GOD SAID...

    And god said "Let the magnetic flux through a closed surface be zero." ??????

    LOL ok i get it now. Let there be light

    What's funny in them becomes a brain teaser for me too! :rofl:
    Well i would not let God take the credit for what Gauss,Ampere,Faraday did! :biggrin:

    i guess it's sound somewhat familiar for Newton!

    Those are Maxwell's Equations which describe electromagnetic phenomena. Light is an electromagnetic wave.

    Somebody is giving God the credit for work done by Maxwell (and Gauss, Faraday, Weber, Helmholtz, Lorentz, Ampere and others) :grumpy:

    A shorter version...

    It can be whittled down to only 2 equations by applying exterior calculus. :wink:

    I doubt Maxwell, et al, would be offended.

    I think Maxwell just described the properties of electromagnetic phenomena. I don't think he actually invented electromagnetic waves. :rolleyes:

    (Saying Maxwell invented ectromagnetic waves is like saying Gore invented the Internet, just because he initiated legislation that made the Internet possible).

    He didn't???
    Didn't Newton invent universal gravitation either??

    How do you think the big dragons could fly unless they were unaffected by gravity, then? :confused:

    I see symbols.

    I've seen t-shirts with

    "And god said
    *maxwell eqs here*

    and there was light"

    I had a laminated copy of that hanging on our refrigerator for years, and after that, in my cubicle at work. A fundamentalist christian saw it and was so offended than when I was away from my desk one day she threw it away. :rolleyes:

    can anyone basically explain some of those symbols to me?

    Loosely speaking, the first equation says that the sum [integral, an adding up process] of the electric field E over a surface A is equal to the charge q enclosed by that surface. We also use something called the dot product, which selects the part of the field pointing in the same direction as the differential area vector dA. :uhh:

    The next one says that the integral of the magnetic field around a path S on the surface A is equal to the electric current flowing through that surface plus any changing electric field inside.

    The third equation says that the electric field integrated over a path around a surface is equal to the rate of change of the magnetic flux through that surface.

    The last one effectively says that there are no magnetic monopoles.

    the equations predict the properties of light, speed as well as it's dual nature, universal constant and the "speed limit"

    Yomamma,

    I am not sure of these eqns, but you are certainly Funny! :biggrin:
