Getting the most action out of least action: A proposal
... Indeed, one finds that for a free particle, the direction 共in the complex plane兲 of the arrow representing the sum at b is always rotated by 45° relative to the direction of the arrow contributed by the least-action world line at b 共which in turn is simply a rotated version of the arrow at the initi ...
