Companies like Enron have learned that small investments in endowing chairs, sponsoring research programs or hiring moonlighting professors can return big payoffs in generating books, reports, articles, testimony and other materials to push for and rationalize public policy positions that damage the public interest but benefit corporate bottomlines.

If, during the Second World War, the United States had retooled its factories for manufacturing bicycles instead of munitions, we’d be one of the healthiest, least oil-dependent, and most environmentally-sound constituents in the Nazi empire today.

One day at Princeton, I noticed there were dead birds on the pavement between the campus buildings, where very large trees were. It turns out it was DDT. At the time, in the early '50s, no one thought DDT was dangerous to anybody but insects. I went down to the Daily Princetonian, the college paper, and tried to persuade them to do a story. They said, "Naw, there's nothing wrong." But that taught me a very important lesson. One, that newspaper people can get very jaded. Second, that you might know something, like an expert chemistry professor, you are not going to apply what you know.
