The day before Thanksgiving, Murph Goldberger died. He was old, he’d been born in 1922; and in those nine decades, he’d collected an extraordinary amount of life. He was drafted right out of college into the Manhattan Project’s brilliant and very young Special Engineering Detachment, where he met his wife, Mildred; and ever after if […]

If you haven’t seen the movie Interstellar, you might not recognize the image above. It’s the black hole that figures prominently in the climax. But even if you have seen the movie, chances are excellent you still don’t know what you’re looking at. I didn’t, anyway, at least the first few days I spent staring at […]
Last week, Lockheed announced it had a small team working on what it calls a Compact Fusion Reactor. Fusion is the opposite of fission that’s used in nuclear plants today; it can produce enormous amounts of energy; the fuel for itis cheap and plentiful; a small fusion engine would solve the world’s energy problems. I […]
You’d think a wall panel in the Galileo gallery in the Galileo wing of the Galileo Museum would be a good place to get an accurate context for Galileo’s historical significance. You’d be wrong: “These astronomical discoveries heralded a revolution destined to demolish an image of the universe that had lasted for two thousand […]
Over the years, I’ve met a number of physicists who had direct or indirect connections with the Manhattan Project and who then spent the rest of their lives trying to get the nuclear weapons genie back into the bottle and the bottle corked. I think of these physicists as the old arms-controllers. They’re impressive people. […]
Tom Painter, a research scientist at NASA’s Jet Propulsion Laboratory in Pasadena, studies snow hydrology in mountains around the world. He’s also a leading expert on the thermodynamics of fairies and princesses. Painter started his fairy-princess sideline a few years ago, when he was asked to lend his expertise to Tinkerbell: Secret of the Wings. In the movie—bear with […]
I was reading the end-of-semester student essays in the Science as Narrative course I teach when one phrase stopped me. Stopped me as in, I didn’t go on: “Darwin was happy to be tasked with telling a fire by its ashes.” Was it an actual thing, I wondered, this “telling a fire by its ashes”? I […]
On Saturday I went to the visitor’s center at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, showed my driver’s license, and got a yellow paper badge to hang around my neck. The occasion: the friends and family day for MMS, the Magnetospheric Multiscale Mission. MMS isn’t one of NASA’s better-known missions. When I googled […]
