  • Learning Stoke’s Theorem by example !

    Calculate CurlF and then use Stokes’ theorem to compute the flux of CurlF through the given surface as a line integral. F  =  y,  x,  x2 + y2    , the upper hemisphere; x2 + y2 + z2 = 1,  z ≥ 0.

    How to add speeds; Galileo and Einstein won’t agree.

    How to calculate the speed of anything, when their speed becomes closer to the speed-of-light.  This article was originally a comment in the linked article;  Why Nothing Moves Faster Than Light. — In order to correct the comment I have made earlier  ” unless something is completely mass-less in its rest-frame ” I also add the following. This…
