Which half? One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?" E.E. Peacock Jr., Seeing With Fresh Eyes science
The source code for SimCity Local Code was Sorkin’s attempt to design a whole city from scratch—with one big twist. The whole thing had been written as if it were the byzantine, nearly impossible to follow codes and regulations for an entire, hypothetical metropolis. The effect is like stumbling upon the source code for SimCity. Sorkin’s exhaustively made point was that, if you know everything about a given metropolis, from its plumbing standards to its parking requirements, its sewer capacity to the borders of its school districts, then you could more or less accurately imagine the future form of that city from the ground up.
