Drones and Aerial Observation
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

A brief history of artificial intelligence
30 August 2021
In the summer of 1956, a group of researchers set out to try to reproduce human intelligence in a machine. More than sixty years later and despite enormous progress, that goal is still out of reach. Just how far, nobody knows.
An introduction to artificial intelligence for a new publication series put out by Aventine, a non-profit research institute that studies how rapid technological advancements and disruptive change will affect life in the decades to come.

What Justin Trudeau got wrong about Quantum Computing
18 April 2016
A video of the Canadian Prime Minister giving an apparently impromptu riff on quantum computing had a few mistakes in it.
This is a critique not so much of his minor errors, but of the media storm which treated his lecture as a sign of genius.

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.
