Mr Hunk, >>Newton's decoded simple laws of nature with reasonably easy mathematics I did not know it was that easy for Newton as it was for you to put it. Galileo would have formulated it if it was that simple. >>Einstein, arguably the genius scientist of all era, on the other hand came from nowhere and formulated an amazing relation between time, mass and velocity whose practicability seemed intricated at that period but eventually proven to be true experimentally. No question that Einstein gave a new direction to science, and is a great one. But just to say he came out of ordinary from all the great ones is a little too much. For me Calculus alone should have dwarfed Einstein's all contributions... and could Einstein have done without it. And who discovered (or co-discovered it)! Maxwell, Planck already had these ideas and some of their own theories before Einstein. >>So in my view its gonna be Einstein all the way. You are probably right. Newton was not less of a genius. ---- The way you put it, anyone by now would have formulated Einstein's theory if not done by Einstein (including me:-).
