I’ve never been in this position, but the person demanding a newspaper or magazine correction—the insider claiming he was quoted out of context; the scientist whose nuanced position didn’t come across, quite; the dead person who’s not really dead—must get a certain satisfaction from seeing the correction printed. It might be the grim satisfaction of a wrong set to rights too late, but satisfaction nonetheless. Then again, in a digital publication, a correction can work to the source’s advantage in some sense. If s/he finds the mistake early enough, an editor can amend it instantly and make sure that (most) everyone reads the correct sentence the first time. Some publications even mark the factual boner with an asterisk, which not only emphasizes the correct version of things, but provides some instant sympathy for the wronged party.
But as a disinterested reader, I’d never gotten actual delight from a correction until a few weeks ago, when the New York Times ran one for an article about study skills and retention (“Forget What You Know About Good Study Habits”). I’d read the uncorrected article online at first, then went back to reread it, for reasons soon ejected from my mind. I’d gotten through half the story, and was going to click through to the second page. And I was grimacing in anticipation of a paragraph I knew was coming up. The author had needed a metaphor conveying something about unintended consequences, and apparently wanted the imprimatur of science. So he fell back on that canned summary of the Heisenberg Uncertainty Principle—you know, the idea that measuring a property of a particle alters the property itself.
Except that’s not what the Uncertainty Principle says. All the Principle actually says, in its entirety, is:
∆x∆p ≥ h/4π
That’s it.
Now if you insist on translating quantum mechanics into English (always risky), the Principle says the uncertainty in a particle’s position (∆x) multiplied by the uncertainty in its speed and direction (taken into account through its momentum, ∆p) always exceeds the number “h divided by four times π.” (The h stands for Planck’s constant, a very tiny number; the π is the familiar constant from circles, 3.14159…) In simpler terms, if you know a particle’s position very well, you cannot know its momentum well at all, and vice versa.
