3:53 p.m., December 2, 1942
The pile as it waited in the cold of Chicago winter to be released to the breeding of neutrons and plutonium contained 711,000 pounds of graphite, 80,590 pounds of uranium oxide and 12,400 pounds of uranium metal. It cost $1 million to produce and build. Its only visible moving parts were its various control rods. If [Enrico] Fermi had planned it for power production he would have shielded it behind concrete or steel and pumped away the heat of fission with helium or water or bismuth to drive turbines to generate electricity. But CP-1 was simply and entirely a physics experiment designed to prove the chain reaction, unshielded and uncooled, and Fermi intended, assuming he could control it, to run it no hotter than half a watt, harldy enough to light a flashlight bulb. He had controlled it day by day for the seventeen days of its building as its k approached 1.0, matching its responses with his estimates, and he was confident he could control it when its chain reaction finally diverged. What would he do if he was wrong? one of his young collegues asked him. He thought of the damping effect of delayed neurons.
"I will walk away -- leisurely," he answered...
[Herbert Anderson]
"At first you could hear the sound of the neutron counter, clickety-clack, clickety-clack. Then the clicks came more and more rapidly, and after a while they began to merge into a roar; the counter couldn't follow anymore. That was the moment to switch to the chart recorder. But when the switch was made, everyone watched in sudden silence the mounting deflection of the recorder's pen. It was an awesome silence. Everyone realized the significance of that switch; we were in the high intensity regime and the counters were unable to cope with the situation anymore. Again and again, the scale of the recorder had to be changed to accommodate the neutron intensity which was increasing more and more rapidly. Suddenly Fermi raised his hand. 'The pile has gone critical,' he announced. No one present had any doubt about it."...
[Eugene Wigner]
"Nothing very spectacular had happened. Nothing had moved and the pile itself had given no sound. Nevertheless, when the rods were pushed back in and the clicking had died down, we suddenly experienced a let-down feeling, for all of us understood the language of the counter. Even though we had anticipated the success of the experiment, its accomplishment had a deep impact on us. For some time we had known that we were about to unlock a giant; still, we could not escape an eerie feeling when we knew we had actually done it. We felt as, I presume, everyone feels who has done something that he knows will have very far-reaching consequences which he cannot foresee."...
[Arthur Compton]
"'Jim [James B. Conant],' I said, 'you'll be interested to know that the Italian navigator has just landed in the new world.' Then, half apologetically, because I had led the S-1 Committee to believe that it would be another week or more before the pile could be completed, I added, 'the earth was not as large as he had estimated, and he arrived at the new world sooner than he had expected.'
'Is that so,' was Conant's excited response. 'Were the natives friendly?'
'Everyone landed safe and happy.'"
Except Leo Szilard. Szilard, who was responsible with Fermi for the accomplishment that chill December afternoon of what he had first imagined alone on a gray September morning in another country and age ago -- the old world undone by the new -- loitered on the balcony, a small round man in an overcoat. He had dreamed that atomic energy might substitute exploration for war, carrying men far away from the narrow earth into the cosmos. He knew now that long before it propelled any such exodus it would increase war's devastation and mire man deeper in fear. He blinked behind his glasses. It was the end of the beginning. It might as well be the beginning of the end. 'There was a crowd and then Fermi and I [Szilard] stayed there alone. I shook hands with Fermi and I said I thought this day would go down as a black day in the history of mankind."

The Vertebrate as a Dual Organism: The Somato-Visceral Animal
"In many regards the vertebrate organism, whether fish or mammal, is a well-knit unit structure. But in other respects there seems to be a somewhat imperfect welding, functionally and structurally, of two somewhat distinct beings:
(1) an external, "somatic", animal, including most of the flesh and bone of our body, with a well organized nervous system and sense organs, in charge, so to speak, of external affairs, and
(2) an internal, "visceral" , animal, basically consisting of the digestive tract and it's appendages, which, to a considerable degree, conducts it's own affairs, and over which the somatic animal exerts but incomplete control."
