There was a blithe certainty that came from first
comprehending the full Einstein field equations, arabesques of
Greek letters clinging tenuously to the page, a gossamer web.
They seemed insubstantial when you first saw them, a string of
squiggles. Yet to follow the delicate tensors as they
contracted, as the superscripts paired with subscripts,
collapsing mathematically into concrete classical entities--
potential; mass; forces vectoring in a curved geometry-- that
was a sublime experience. The iron fist of the real, inside
the velvet glove of airy mathematics.
