look at Figure 2 ... the agents seek only one neighbor of their own color. Again the simulation begins with a random distribution (Frame 1). This time sorting proceeds more slowly and less starkly. But it does proceed. About a third of the way through the simulation, discernible ethnic clusters have emerged (Frame 2). As time goes on, the boundaries tend to harden (Frames 3 and 4). Most agents live in areas that are identifiably blue or red. Yet these "people" would be perfectly happy to be in the minority; they want only to avoid being completely alone. Each would no doubt regard itself as a model of tolerance and, noticing the formation of color clusters, might conclude that a lot of other agents must be racists.
While I had been studying the location choices of high-tech industries and talented people, Gates had been exploring the location patterns of gay people. My list of the country's high-tech hot spots looked an awful lot like his list of the places with highest concentrations of gay people. When we compared these two lists with more statistical rigor, his Gay Index turned out to correlate very strongly to my own measures of high-tech growth. Other measures I came up with, like the Bohemian Index---a measure of artists, writers, and performers---produced similar results.
US National Science Foundation data show that the United States is currently awarding only about 200,000 bachelor's degrees in engineering and science, little changed from trends in the mid-1980s. By contrast, Asia's annual graduates of science and engineering students (for China, India, Japan, South Korea, and Taiwan, combined) has now hit approximately 650,000 per year; that's up over 50% from the graduation rate in the mid-1980s and fully three times the comparable degree production rate in the US.
President Bush yesterday dismissed two members of his hand-picked Council on Bioethics — a scientist and a moral philosopher who had been among the more outspoken advocates for research on human-embryo cells.
In their places he appointed three new members, including a doctor who has called for more religion in public life, a political scientist who has spoken out precisely against the research that the dismissed members supported, and another who has written about the immorality of abortion and the "threats of biotechnology."
