Michael Crichton has a way with words.

And this lecture to the National Press Club uses them effectively. Some of my favorites follow. Read the whole thing and pick your own.

"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."


And the real deal that Pope Algore would never admit to.

"So we all tend to give science credence, even when it is not warranted. I will show you many examples of unwarranted credence tonight. But here’s an example to begin. This is the famous Drake equation from the 1960s to estimate the number of advanced civilizations in the galaxy.

N=N*fp ne fl fi fc fL

Where N is the number of stars in the Milky Way galaxy; fp is the fraction with planets; ne is the number of planets per star capable of supporting life; fl is the fraction of planets where life evolves; fi is the fraction where intelligent life evolves; and fc is the fraction that communicates; and fL is the fraction of the planet’s life during which the communicating civilizations live.

The problem with this equation is that none of the terms can be known. As a result, the Drake equation can have any value from “billions and billions” to zero. An expression that can mean anything means nothing. The mathematical appearance is deceptive. In scientific terms—by which I mean testable hypotheses—the Drake equation is really meaninglessness."
