I edited and wrote part of a short book published by New America in July 2015 and freely available online, about how drones are being used in new ways around the world. It's meant to be useful to people who want to fly drones.The Pioneer Detectives
I published a short book with The Millions.
It's the story of the Pioneer Anomaly, a long-standing mystery. The book is short and fun—the length of a novella—but also, in the words of Amazon's reviewer, "powerful and sad". If you've got any curiosity about how NASA works behind the scenes or why scientists believe what they do, I think you'll enjoy the book.
It is available on Amazon as a Kindle Single and also on Apple's iBooks.Drone Wars
I wrote a chapter on the long history of drone technology going back to the early 20th century in this edited Cambridge University Press volume.

AI Has Helped Solve of Math’s $1 Million Millennium Prize Problems
8 September 2026
Mathematicians at OpenAI showed that the Navier-Stokes equations, which describe how fluids flow, can sometimes “blow up.” But the massive result is not without controversy. This article tells some of the story of how the ideas behind the proof were developed by Diego Córdoba of the Institute for Mathematical Sciences in Madrid and Luis Martínez-Zoroa of CUNEF University.

Math doesn’t have to be boring, but it does have to be math
The New York Times editorial board doesn’t understand the first thing about mathematics, and this is a big problem.
