Correction: An article yesterday about a tiny force in quantum mechanics that could be used in future microscopic devices referred incorrectly in some copies to the size of the force measured when two metal plates were placed within one 40-thousandth of an inch of each other. It was one 300-millionth of an ounce, not one 300-thousandth. […]

Alex Wellerstein is an historian of science at the American Institute of Physics with an obsession about the atomic bomb and in particular, about the patents taken out on it. Patents on the atomic bomb seem odd: apparently the government wanted to be sure it owned the rights, and not the “private contractors, private scientists, […]
You probably know this. In August, 1939, Einstein wrote a letter to the American government. German scientists had announced that the energy holding an atom together could be released – in fact, 2.2 pounds-worth of uranium atoms would equal 10,000 tons of TNT. Einstein said this implied a new kind of bomb that Hitler’s government […]
For the holiday season we here at LWON are giving ourselves the gift of confronting our fears. We are choosing our own most daunting science-related subjects and writing about why they scare us. Oh, physics. It’s flummoxed both Cassie and me. First, you’ll see Cassie’s delightful video about a not-so-delightful experience that soured her on the […]
For the holiday season we here at LWON are giving ourselves the gift of confronting our fears. We are choosing our own most daunting science-related subjects and writing about why they scare us. My father wasn’t a physicist, but he could work wonders with gravity. He’d be showing me how to change a flat, or fix […]
The death of Neil Armstrong in August prompted no end of tributes invoking heroism, patriotism, vision, courage, valor, and all sorts of other abstractions. Understandably so. Armstrong’s giant leap was in fact the first baby step in one species’ attempt to leave home. Less in the news, though, was a more concrete matter: hard science. The […]
This was originally posted June 8, 2010 and probably ten people read it. I hope you don’t mind my running it again. It reminds me of my favorite Abstruse Goose. The picture’s a little alarming, but justly so. I had two trees in the front yard, and I’d watch the squirrels jump between them, across […]
From “On Being the Right Size,” by J.B.S. Haldane: “You can drop a mouse down a thousand-yard mine shaft; and on arriving at the bottom, it gets a slight shock and walks away. A rat is killed, a man is broken, a horse splashes.” Recently, a couple of my friends have fallen. One, a woman, […]
