Researchers find history in the diagrams of Euclid’s Elements

The fourth book of Euclid’s Elements, a 2,300-year-old geometry text, includes directions for constructing a 15-sided polygon inside a circle. The first step is familiar to geometry students: Draw an equilateral triangle and a regular pentagon so their vertices touch the circle and the two shapes share one vertex. In addition to text directions, the Elements included diagrams that

Zombie physics

For Alex Alemi and Matt Bierbaum, physics graduate students at Cornell University in the US, there really was no escaping the zombies – those fictional reanimated human corpses that feast on the living. In autumn 2011 they were required to complete a project for a class on statistical mechanics taught at Cornell by James Sethna

Charting the history of western art with math

  For more than a century, researchers have used statistics to study writing style in a sort of literary forensics technique called stylometry. In 1901, physicist T. C. Mendenhall famously measured word-length frequency in William Shakespeare’s works and reported that the writer’s style was awfully close to that of fellow writer Christopher Marlowe, fueling rumors

Can an Equation be a Poem?

April is Mathematics Awareness Month. April is alsoNational Poetry Month. Coincidence? Yep, almost definitely. But it’s also an opportunity: I’d like to propose that we—you and I, at least until the end of this blog post—merge the two and celebrate the first-ever Mathematical Poetry Month. No fooling. Connecting math to poetry isn’t a new idea. Archimedes

Foraging flights

First, he tracked basking sharks—filterfeeding leviathans that look like supersized great whites—in the coastal waters near Great Britain, and then Atlantic cod, leatherback turtles, Magellanic penguins, and bigeye tuna. He’s wrangled and tagged ocean sunfish, blue sharks, and shortfin mako sharks (and claims success by the fact that he still has all his fingers). Only after David Sims had exhausted many
