When Alson Kelen was young, he used to lie at night against his father’s arm, on an island where there were no lights and no cars. He listened to waves slapping against wet sand, the breeze shaking the palm fronds, the delicate crackling of a coconut shell fire. As the purple-blue evening gave way to night, […]
My husband had surgery and complications and is recovering slowly, entailing a lot of medical appointments and difficult information and difficult decisions and long absences from home and office. Home and office have taken advantage of this to do bad things. You might think this increase in badness is due to psychology or coincidence; it’s […]
Caveat: I’m possibly having something like a Cassie-Willyard-Hubble-Moment here – in this case, I learn something new, don’t quite understand it but get all excited about it, and it’s, you know, wrong. Never mind because I’m all excited anyway because science has found a new way of being confident that what you know is right. […]
As of yesterday, May 20, LWON has been alive for five years. LWON is a little surprised at this and pretty pleased with itself. In celebration, two of our brilliant alumni wrote guest posts listing the Top Five Things They Wanted to List the Top Five Of. Today, Five People of LWON announce the best […]
Last month DC Science Comedy invited LWON’s own Mr. Cosmology to participate in one of the group’s Science Comedy Nights. Mr. Cosmology accepted. Empirical evidence follows.
Charles Hard Townes died a week ago, aged 99. He was a physicist at Berkeley who came up with the principle of the laser; at age 98, he’d stopped coming into the office every day. His obituaries are thorough and their praise is justified. I’d met him for reasons the obituaries don’t mention. He helped […]
Dear LWON readers, I’d like to ask you a question. Twice recently I’ve written about properties of black holes that blow my mind. In each instance, my inspiration was a detail from a movie. First was Interstellar. The great gravitational grip of the black hole in that movie, as is the case for all black holes, distorts […]
In the 1992 documentary A Brief History of Time, Stephen Hawking describes what we would see if we were observing an astronaut nearing a black hole’s event horizon—the barrier beyond which gravitation is so great that not even light can escape. He invites us to imagine that the astronaut is wearing a watch, and that […]
