Why shadows move faster than the speed of light, what “information” means in physics, and why Albert Einstein used a geometry equation to answer George Bernard Shaw’s cheerful critique of science (C = 2πr).
As the radius of a circle increases, the circumference more than doubles. Thus, if r is taken to be our knowledge of everything, and it continually grows, C will more than double. And C here means our ignorance (at least that which we know we don’t know). The end result: C more than doubles every time r increases. And that is why Shaw is correct, and why our ignorance will grow as our knowledge does.
