"To show you how small my own contribution was and how much I inherited from the past, let me tell you that the basic equation of my theory is not even my own. It was discovered some fifty years prior to this day—some ten years before I was born.

"For on the evening of February 9, 2909, in Central Park, on the very site of this amphitheater, my father, suddenly struck with an idea, mentioned an equation to my mother. That equation:

i = (b/a) π i e/μ..."

was the inspiration for my own theory. So you can understand just how little I have contributed to the 'invention' of The Tension Energy-Dynamics Equations—"

FitzJohn glanced at the first card and went on: "Let us consider, now, the possible permutations on the factor

e/μ..."

I yelled: "That's plenty. Cut!" and before the first word was out of my mouth the controller and the C-S were shouting, too. Yarr blanked out the crystal and brought up the lights. We were all on our feet, looking at each other excitedly. Yarr jumped up so fast his chair went over backward with a crash. We were in a fever because, boys, that day happened to be February 9, 2909, and we had just about two hours until evening.

The controller said: "Can we locate these FitzJohns?"

"In two hours? Don't be silly. We don't even know if they're named FitzJohn today."

"Why not?"
