    May i know the physical meaning of the following:

    (1) Curl of a vector field A(x,y,z)
    (2) divergence of a vector field A(x,y,z)
    (3) directional deriative of G(x,y,z)
    (4) gradient of a scalar field G(x,y,z)

    Tac-Tics gives possible interpretations of those in a particular application. There is NO general "physical meaning" of a mathematical concept- mathematics is not physics.

    These concepts were originally developed because of physics, and even the purest mathematics student should develop the physical intuition of it, while simultaneously developing the topic rigorously.

    If you get a computer with a killer graphics card that can do floating point matrix computations really fast, then it would be stupid to write a program that uses the CPU instead. As humans, we have a killer "graphics card" and "physics card" built into our mind - it would be stupid not to use it.
