Last weekend, I played a game with my family called Placing the Past. Each player gets cards that describe different historical events. You arrange the cards in the order you think the events happened, then check your guess. I kept wishing the game included more science history, so I decided to make my own, short […]

Wednesday night, Washington, D.C.: Because my work life is slightly on fire right now, and because I already spent 10 hours of this day either sitting in front of my computer or walking around in circles talking to people on the phone, I present to you a photograph of a sunrise in the Caribbean last […]
These little friends got a ride home with me from the gym the other morning, stuck into the spiderwebs that cling to the side mirrors. There were more all across the front of the car, stuck in the small valley between the folded windshield wipers and the glass. I was delighted—could this be seed dispersal […]

My neighbor likes to ask big questions about big ideas. He’s not pretentious and doesn’t pontificate, so I think he just likes big questions. Anyway, the other day he asked what the necessary components of an ideal public education were. “Writing,” I said, naturally. He agreed partly because, he said, good writing involves good thinking.

Arizona winter night, stars over pines, my buddy and I were heading for a hot tub on the outskirts of Flagstaff when a phone rang. It was a mutual friend, Jayme Dittmar, a dog musher on a 1,300-mile expedition by dog sled from Nome, Alaska, to the village of Utqiagvik on Point Barrow. She was […]
