Sorry, I am superficialin my words. "Your Comp" referred to the idea your 'biological information processors in your skull' handles when you consider Bruno's "comp".
I missed that Asimov spot. He probably did not consider the neuronal input on 'running' vs. acknowledging the cliff. I participated for 2 decades in an enjoyable Wednesday Brownbag Lunch with the Drew Univ. ret. professors when one of us calculated out for us that it is physically impossible to play base-ball: the time to process visually the 'throw' is longer than the travelling time of the ball, so nobody can hit it. What led to 'deep' philosophical discussions.<G> My question about 'atomic size' was in consideration of the map of a neuron and the size avalable in the skull. Dinos did not parade brains of million times more than ours. Remember the Neandertals? with larger skulls and not necessarily more sophisticated brain-complexity than the Cro-Magnons? I always asked how much fat or other irrelevant matter was filling those bone boxes? Anthropologists do not like such questions.
