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 […]

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 […]
My dad and I share an obsession with endurance sports. We don’t just love to get outside and ride our bikes, we actually feel antsy and anxious if we go too many days without working up a sweat. As I’ve written elsewhere, our compulsion for exercise has a genetic basis. Dad and I probably have […]
My mother was an old lady, she’d lived a good and useful life, and she died a year and ten days ago. I hadn’t been keeping track of her death’s anniversary but I didn’t need to; I only had to figure out why I was walking around feeling, for no good reason, sad. One of […]
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, […]
I asked my husband, who’s a physicist and a pilot, how airplanes stay up in the air. A question like that makes him happy. “It’s the wings,” he said, “They provide lift.” “What’s lift?” I said. “It’s Bernoulli,” he said. “The faster air moves, the lower its pressure. ” I’m used to these answers that are […]
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. […]
(This post is the second in a two-part series. I adapted it from a keynote address I delivered in the summer of 2010 at Goddard College, in Plainfield, Vermont, where I teach in the MFA Writing program. The essay is part of a collection of talks by Goddard writing faculty that have been collected in […]
