Dear readers, dear friends, As I write this, on the afternoon of November 9, 2016, the future looks very dark. If you respect reason and truth, if you care about the planet we depend on, if you believe that biology is just biology, not destiny, then I expect the future looks dark to you, too. I…
On Monday, at an international meeting of geologists in Cape Town, South Africa, the 35 members of the Anthropocene Working Group summarized their seven years of work. Chief among their preliminary findings is that the current human-dominated chapter in our planet’s history, informally known as the Anthropocene, is geologically real. That’s “real” as in “recorded in the earth’s rock layers.” The report is the latest…
This is the latest in a series in which science’s metaphors offer the explanations of and guidance for the most cryptic of life’s problems. A few weeks ago I was at a conference about galaxy evolution. In the titles of many talks was the puzzling phrase, “secular evolution.” Secular? as opposed to religious? so secular…
I suspect this isn’t really a science metaphor, but I got caught up in the word. I had a friend who’s married to a hospital doctor, and he brought home many work-related words of interest: “mother-of-record,” for instance, meant that he wasn’t going to be the one taking cupcakes to their kid’s class in the…
I’ll go home tonight, I’ll open the front door, I’ll yell, “Hey sweetie, hi!” Then Sweetie will yell, “Hello, young Ann.” I’ll look at the mail, then I’ll yell again, “Did you pick up the salmon?” And he’ll say, “Yep, it’s in the refrigerator.” And then I’ll look over the mail and start to throw…
Science, so useful to our lives in so many ways, also usefully supplies metaphors from which we may find comfort or edification. An astronomer told me that the galaxy we live in, the Milky Way, was surrounded by a tenuous halo of hot gas. “How can gas stay hot, out there in space?” I asked. …
I was helping an astronomer write a sentence. It was about disentangling the color a supernova has intrinsically, from the reddening in its color caused by cosmic dust. He wrote he wanted to “break the degeneracy” between the colors. Break the degeneracy. I got so excited. I’d always thought degenerates were people who didn’t, for…
My mother was an old lady, she’d lived a good and useful life, and she died a year and ten days ago. I hadn’t been keeping track of her death’s anniversary but I didn’t need to; I only had to figure out why I was walking around feeling, for no good reason, sad. One of…
