Missing Michael Crichton already

Wise words from a lecture delivered by the late author in 2003:

Let's be clear: The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period. . . .

I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way. . . .

To an outsider, the most significant innovation in the global warming controversy is the overt reliance that is being placed on models. Back in the days of nuclear winter, computer models were invoked to add weight to a conclusion: "These results are derived with the help of a computer model." But now large-scale computer models are seen as generating data in themselves. No longer are models judged by how well they reproduce data from the real world -- increasingly, models provide the data. As if they were themselves a reality. And indeed they are, when we are projecting forward. There can be no observational data about the year 2100. There are only model runs.

This fascination with computer models is something I understand very well. Richard Feynman called it a disease. I fear he is right. Because only if you spend a lot of time looking at a computer screen can you arrive at the complex point where the global warming debate now stands.

Note to self: Read "State of Fear," the book Crichton's detractors can't stand because it's a rebuttal to Al Gore's greenishness in novel form. His
other books are good, too, albeit sometimes unwieldy.

Another point of view: Michael Crichton dies

Crichton was a great mind and will be sorely missed. I read 'State of Fear' and it does rebut Gore nicely.

That said, it is a terrible novel.

Those who've already drunk the Kool-Aid will assume that a silly plot invalidates the hundred or so pages of meticulously researched end-notes, charts and graphs that are anything but fictional. Such people have already committed to their faith and will not be swayed.
