Earlier this month (April 8, 2024), a total solar eclipse cut through Mexico, the United States, and Canada. Total solar eclipses are paramount spectacles. It’s unlikely you will see anything else in your short, pointless life that will match a total eclipse. Thus, whenever an eclipse passes nearby, you should endeavor to place yourself in … Continue reading The First Total Solar Eclipse of the 21st Century

Math Eras
As part of a larger project, I needed a simple timeline for the history of mathematics. I kicked around a bunch of candidates but settled on the following: Old Tally — before 4000 BCE Bronze River — 4000 BCE to 1001 BCE Early Philosophic — 1000 BCE to 301 BCE Euclidean — 300 BCE to … Continue reading Math Eras
J graphviz’s Euclid’s Elements
In Sarah Hart’s new book Once Upon a Prime she relays John Aubrey’s account of the philosopher John Hobbes’s1 first exposure to Euclid’s Elements. Being in a gentleman’s library Euclid’s Elements lay open, and ’twas the forty-seventh proposition in the first book. He read the proposition. “By God,” said he, “this is impossible!” So he … Continue reading J graphviz’s Euclid’s Elements
Sympathy for Ptolemaic Epicyclers
Histories of science tend to cast “old theory holdouts” as uncouth, backward, prejudiced, and stinky nitwits. If you don’t immediately jump on the shiny new science bandwagon you’re on the wrong side of history and doomed to a legacy of ridicule and disdain. Mind you, these just so histories fail to mention that most new … Continue reading Sympathy for Ptolemaic Epicyclers
How Many Authenticated Ancient Mathematical Artifacts are Known?
“How many authenticated ancient mathematical artifacts are known?” I recently asked myself this question while researching the history of mathematical proof. Ultimately, all historical theories must answer to the evidence. For mathematics, this means studying surviving parchment documents, cuneiform tablets, bamboo strips, bone markings, Stella inscriptions, calculating boards, and other objects, that inform our mathematical … Continue reading How Many Authenticated Ancient Mathematical Artifacts are Known?
On Eponymous Erasure
While slumming on the Internet I came across a woman complaining. Imagine my astonishment! The lady1, let’s call her Karen, had an esoteric complaint, it was: The Pythagorean Theorem was known long before his birth. Calling the theorem “Pythagorean” is a form of erasure. Oh my! Apparently, attributing a well-known mathematical result to a person … Continue reading On Eponymous Erasure
Neowise Nostalgia
Comet Neowise is fading fast. For the last two weeks, I've been watching Neowise climb higher and higher in the early evening northwestern sky. Neowise was a welcome sight in this shit-storm (2020) year. Gazing at its diffuse tail takes your mind off the Wuhan Coronavirus1 and the global, mostly self-inflicted, economic clusterfuck it caused. … Continue reading Neowise Nostalgia
Who Thought Blinking Windfarms was a Good Idea?
Click here for a PDF version of this post. One night, a few weeks ago, I was driving west on I86 near American Falls when I spotted a long string of blinking red lights. The lights stretched over a large arc of the horizon. My first thought was “Jesus H. Christ now what?” As an … Continue reading Who Thought Blinking Windfarms was a Good Idea?
Don’t be a Weenie Launch Cassini
Future generations will remember Bill Clinton for two things, not having sex with that woman and authorizing the launch of Cassini. I was working in Dallas Texas in the months before Cassini's launch. It was 1997 and the Internet was just beginning to disrupt everyday life. Google was morphing from a thesis to a company … Continue reading Don’t be a Weenie Launch Cassini
Still Totally Awesome
The total solar eclipse of August 21, 2017, was my fourth complete solar eclipse. I've seen two annular eclipses, 1994 and 2012, and two total eclipses, 2001 and 2017. Annular eclipses, or rings of fire, are worthy spectacles but nothing compares to a total solar eclipse. Some things have to be experienced to be fully … Continue reading Still Totally Awesome
