Yesterday I related the official version of how photons from the star Arcturus triggered an electrical signal that lit up the 1933 World’s Fair in Chicago. My research into that event, however, has sent me deep into the weeds. Most historical accounts claim that four observatories — Yerkes, Harvard College, Allegheny, and the University of […]

Arcturus, in the constellation Boötes the Herdsman, is the fourth-brightest star in the sky. It’s visible high overhead in late spring twilight, but you can also find it low in the west after sunset in September.

In 1908, a young Lithuanian immigrant named Pauline Newman got a job at the Triangle Shirtwaist Company, then one of New York City’s biggest garment factories. She worked as a “cleaner,” trimming threads off the new clothes and boxing them for shipment. It was dull, tiring work, with bullying bosses who forced the workers to […]
Physicists, like the ancient Greeks, like to gossip about their gods. A few days ago, three physicists* were talking on Twitter** about a review by a fourth physicist, Freeman Dyson, of a biography of one of these gods, J. Robert Oppenheimer, and about his war with another one, John Archibald Wheeler. Physicist #1: Oppenheimer did […]

The upshot is, the whole of reality isn’t measureable all at once. The more you think about […]
Time again to reach into the “Ask Mr. Cosmology” mailbag and see what readers want to know about . . . The Wonders of the Universe! First up, some questions from the comments portion of the previous installment of “Ask Mr. Cosmology.” Q: Is protest against God morally acceptable? Mr. Cosmology: Unlike Richard, Mr. Cosmology knows better than to venture into […]
The Ramsay family has lived at the Bamff estate, 1300 acres of heathery hills and woodlands in eastern Scotland, for nearly eight centuries. Today, environmentalists Paul and Louise Ramsay share the property with three families of beavers. The couple brought the animals to Bamff in 2002 as part of a controversial effort to reintroduce European […]
Last July I ended a post on the Higgs boson with an admonition: “Just don’t get me started on this ‘God particle’ business.” But did Christie listen? “I’m sharing it with my husband,” she emailed me about the post. “This whole ‘god particle’ thing has been driving him completely crazy.” The term, at least in the […]
