In any attempt to bridge the domains of experience belonging to the spiritual and physical sides of nature, time occupies the key position.

You cannot disturb the tiniest petal of a flower without the troubling of a distant star.

To the pure geometer the radius of curvature is an incidental characteristic - like the grin of the Cheshire cat. To the physicist it is an indispensable characteristic. It would be going too far to say that to the physicist the cat is merely incidental to the grin. Physics is concerned with interrelatedness such as the interrelatedness of cats and grins. In this case the "cat without a grin" and the "grin without a cat" are equally set aside as purely mathematical phantasies.
