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.

Why Johnny Can’t Add Without a Calculator
25 June 2012
Technology is doing to math education what industrial agriculture did to food: making it efficient, monotonous, and low-quality.
How and why graphing calculators, educational software, interactive whiteboards and the like undermine actual learning in elementary, middle and high schools.
