Nothing is entirely trustworthy. Friends are inconstant; presidents and professors are making it up; your grandmother didn’t always know what she was talking about; your very senses can fool you; and one of these fine days even the sun will blow up. Where is the touchstone, the standard, the fundamental reference frame? Where is the […]

One of the campuses where I teach is haunted. Everybody says so. They hear noises in the night. They encounter cold spots. They come to work in the morning and find a seemingly immovable file cabinet in the middle of a hallway. My role, you might not be surprised to hear, is that of resident […]
Abstruse Goose added a mysterious little tag that says something like, “Now, how many pop culture references can you find?” None for me, not one, geezer that I apparently am. But I did get the astronomy/physics references. The stardust one: maybe you already know this but most every element — the lithium in our batteries, […]
I haven’t had anything to do with biology since I wrote an article years ago about sleeping pills. I found out that the drugs used by 60-gazillion insomniacs to put themselves to sleep are not the chemicals the brain uses to put us to sleep naturally.

The book’s complaint is standard English major stuff, […]
Today, I’m venturing backstage at Last Word on Nothing, a rather frantic place at the best of times. Ann has just published a very cool new book on a group of astronomers who created this beautiful map of the universe, the Sloan Digital Sky Survey. Her book is called A Grand and Bold Thing, and […]
This is a photograph — meaning, it’s real — taken from 114 million miles away on the far side of the sun. The brightest little dot in the lower left is the earth. The less bright dot near it is our moon. Click on it: it almost makes you cry.
On July 28, 2010, nearly 900,000 galaxies were put into a public database, and this is Galaxy #1, or SDSS J000000.41-102225.6, and don’t tell me astronomers don’t know how to name things. Galaxy #1 is probably an elliptical; the rest of the 900,000 are either ellipticals or spirals or something else, and were identified as […]
