triple-paned, polarizing windows of Jorj Helmuth's bedroom in the Thinker's Foundation, yet the clock in his brain awakened him to the minute, or almost. Switching off the Educational Sandman in the midst of the phrase, "... applying tensor calculus to the nucleus," he took a deep, even breath and cast his mind to the limits of the world and his knowledge. It was a somewhat shadowy vision, but, he noted with impartial approval, definitely less shadowy than yesterday morning. Employing a rapid mental scanning technique, he next cleared his memory chains of false associations, including those acquired while asleep. These chores completed, he held his finger on a bedside button, which rotated the polarizing window panes until the room slowly filled with a muted daylight. Then, still flat on his back, he turned his head until he could look at the remarkably beautiful blonde girl asleep beside him. Remembering last night, he felt a pang of exasperation, which he instantly quelled by taking his mind to a higher and dispassionate level from which he could look down on the girl and even himself as quaint, clumsy animals.

Next he glanced at the message tape beside his phone, washed down with ginger ale a vita-amino-enzyme tablet, and walked to the window. There, gazing along the rows of newly planted mutant oaks lining Decontamination Avenue, his smooth face broke into a smile. It had come to him, the next big move in the intricate game making up his life—and mankind's. Come to him during sleep, as so many of his best decisions did, because he regularly employed the time-saving technique of somno-thought, which could function at the same time as somno-learning. He set his who?-where? robot for "Rocket Physicist" and "Genius Class." While it worked, he dictated to his steno-robot the following brief message:
