First, do no harm. It’s a commandment often incorrectly attributed to the Hippocratic oath yet it provides an ethical foundation for modern medicine. The American Medical Association’s principles of medical ethics begins, “A physician shall be dedicated to providing competent medical care, with compassion and respect for human dignity and rights.” But what happens when a […]

A couple of months ago astronomers reported the discovery of an unusual six-component “gravitational lens”—six images of the same object coming at us from slightly different positions in the sky. As light traveling across the universe passes a large mass, the gravity from the mass will serve as a kind of lens, bending the rays. […]
I love museums, and my hometown, Washington, D.C., is full of them. You’ve heard of the big ones—the Air and Space Museum with the Wright Brothers’ plane, the Natural History Museum with its elephant and dinosaurs. We’ve got privately-owned tourist bait, like the Spy Museum and a branch of Madame Tussauds. Then there’s a pile […]
The sidewalk astronomer – usually a star-haunted amateur setting up a personal telescope on city sidewalks for both money and love – is familiar with doubt. Mr. Tregent, 1856: “Sometimes when I have been exhibiting, the parties have said it was all nonsense and a deception, for the star was painted on the glass. If […]
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. All you need to do is let your eye follow the stars of the handle of the Big Dipper, […]
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 […]
