Snapshot: Anti-Christmas Tree

(An unauthorized continuation of “Things We Like”) Scattered along the deep ravines and canyons where I live are trees called ghost, or sometimes grey, pines. The trees are scraggly and uncharismatic. “Scarcely in any sense a beautiful tree,” Willis Jepson, one of California’s early botanists, wrote of them in 1901, they give “no comfort of […]

Following Shadows Around the Room

Daylight Savings Time swapped out almost a month ago and I’m still off kilter. Who thought of such an assault on the senses? We’re sapiens and all, masters of adaptation, but mind and body don’t like to be parted. I prefer watching light shift day by day, squares of sunshine stepping forward and back across […]

X-ray Vision

My daughter had her braces removed a couple of weeks ago. This was a big occasion for her and to mark it I told her she could have whatever heretofore verboten food she wanted. She asked for gum—her first in about two years. I handed her the pack when she came out of the orthodontist’s […]

Author of Machines Who Think: A Personal Inquiry into the History and Prospects of Artificial Intelligence and other seminal works, I had a request in to interview her for a number of projects but never heard back. Now I know why. In a pitch for a Netflix show, […]

Snapshot: Spider Man

It’s something that some orb spiders do, a web embellishment whose purpose is debated. It’s called a stabilimentum, and arty spiders named Shea or Absinthe (Charlotte is just too on the nose) spin it out aciniform silk — different material than they use for the surrounding web. Typically its done in concentric circles or an […]

SHE?

Some things I seem to write about over and over, year after year, far into the night. One of these things is the situation of women in science, usually physics and/or astronomy. The subject bores me until I start thinking about it, and then I get sort of irate. Enraged actually. Well, flame-throwingly furious. The […]
