Garwin: the Movie opens with an old, steady, precise hand on a computer keyboard, scrolling through now-declassified* documents. Harry Truman and Dwight Eisenhower make announcements, and newspapers flash headlines about our splendid new hydrogen bomb. Then the blossom of a mushroom cloud unfolds; and John F. Kennedy talks about Russian missiles in Cuba; and the […]

Kepler strikes again! A couple of weeks ago, in a two–part essay, I wrote about a 1608 book by the German astronomer Johannes Kepler that scholars consider the first work of science fiction: Somnium—Latin for The Dream. This past week, I got to thinking about Kepler’s book again, after the discovery of dwarf planet 2012 VP113 (which the discoverers have nicknamed […]
(Part 2 of 2; Part 1 appeared yesterday.) Harry’s utterance “Damn damn Kepler on the Moon damn damn” immediately entered the lexicon of our little messenger world. I then introduced it to my non-work friends, who likewise adopted it as an absurdist catch-all. For years afterward my only knowledge of Kepler was as a punch […]
My first job, post-paper route, was as a messenger in the advertising department of the Chicago Tribune. As a 15-year-old aspiring journalist (and, yes, underage hire), I thought the experience might be a career path to Woodward and Bernstein heights. By coincidence, the day I started—May 1, 1974—was Watergate Wednesday, the same day that the Tribune was […]
You cannot walk more than a dozen paces at the Kavli Institute for Theoretical Physics, a cloister of sorts for the more theoretically- and mathematically-inclined of the science community, without happening onto a chalkboard. Secured on at least one wall of each small office on the building’s two floors is a spacious chalkboard. Chalkboards run […]
This week, it seems like all I am seeing in the news is sports. Athletes, trained to the very pinnacle of human possibility, competing for money, fame, and above all, glory. For Americans, the centerpiece is the Super Bowl, which will scoop up more than four times more viewers than an average Winter Olympics day. […]
Halton Arp — “Chip” to his friends — died in Munich on December 28, 2013, and with him a cosmological banner has fallen to the ground. It’s a banner that younger astronomers may choose to take up. If they do, however, they should be cautious: it could mean the end of their careers. As a […]
Ok, so y’all know about how, in general relativity, gravity slows time. Clocks closer to something massive and more strongly attracted to it run slower. And clocks farther away and less attracted run faster. I’d explain this to you in more detail but I’m busy. Anyway, AG can use the different times on his different […]
