“It’s a way to frame the problem,”

As something of a follow up to my last post, there’s a great little item about the development of the Drake equation over on National Geographic. Here’s a good passage:

It’s this kind of guesswork that tends to inflame the Drake equation’s critics, those who complain that the equation isn’t predictive, is too open-ended, and doesn’t provide any answers. But “predictive” isn’t really what Drake ever intended.

“It’s a way to frame the problem,” says MIT astrophysicist Sara Seager, about the equation. “In science, you always need an equation—but this isn’t one you’re going to solve. It just helps you dissect everything.”

Definitely worth reading, as well as thinking about.
