Science Metaphors (cont.): Degeneracy

I was helping an astronomer write a sentence.  It was about disentangling the color a supernova has intrinsically, from the reddening in its color caused by cosmic dust.  He wrote he wanted to “break the degeneracy” between the colors.  Break the degeneracy.  I got so excited.  I’d always thought degenerates were people who didn’t, for […]

Is That Guy Really, Really Smart?

A friend I run into regularly says, “Hey, Ann.  Do you know that guy from around here who won that Nobel whatever?”  He means Adam Riess, and yes, I know Riess.  I’ve interviewed him, I say hello, he says hello back.  “I have a question for you,” says my friend. “Is your Nobel guy really, […]

Guest Post: Not So Fast

The news of a detection of faster-than-light speed neutrinos by the OPERA experiment stunned the physics and astronomy community last week.  I read the paper, and I listened to the talk from Geneva over the Web. This is seriously weird stuff! Faster-than-light speed neutrinos!? The talk was filled with wonderfully arcane geodetic methods for measuring […]

Exo-Freakshows

I’ve had occasion in these pages before to write about searches for alien planets and alien life and for both, to register the loftiest disdain.  I mean, crissakes, the universe is jam-packed with philosophy-shattering freakshows, and we’re looking for things we already know exist?  Planets and life are not news.   I learned this outlook from […]

What’s in a Name

The best thing that ever happened to the Big Bang is its name. For scientists, the acceptance of a scientific concept depends on its explanation of existing data, its prediction of observable phenomena, the observation of those phenomena, and the duplication of those results. But for non-scientists—well, for scientists, too—the popularity of a concept can come […]

Abstruse Goose: A Brief History of Us

AG’s sneaky caption this time is “. . . we are the universe made manifest, trying to figure itself out. — Delenn or Carl Sagan.”  It’s apparently a quote from Delenn who is apparently some scifi character who says portentous things.  Carl Sagan was real; also said portentous things; and undoubtedly said something like that, […]

Bang? Whimper? Whatever.

What is the fate of the universe? Cosmologists are converging on an answer, and it ain’t pretty. Or so I gather from people who, hearing that the latest science favors a universe that goes on forever, growing colder and colder, lonelier and lonelier, ask me, “Don’t you find it depressing?” The short answer is, No. […]

Pulling the Primary

Turn right at Alamogordo, pass High Rolls, and 9000 feet up into New Mexico’s Sacramento Mountains, turn right again and go 15 miles along a narrow switchback two-lane, turn off on the Apache Point road, pass a pond, and hit the dead end at Apache Point Observatory, a cluster of utilitarian buildings.   Inside one building […]
