An interactive exploration of how GPS works: from the speed of light and trilateration to the cheap clock problem and Einstein's relativity corrections.

Researchers fitted five Australian magpies with GPS trackers to map their movements, but within an hour the birds began helping one another remove the harnesses, turning a failed tracking experiment into an unexpected observation of cooperation and problem-solving
Five Australian magpies helped each other remove their GPS harnesses within hours, ending a tracking study and revealing rare cooperative behaviour.

How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

Relativity Park: Walking Speed of Light
Special relativity simulator in which light crawls along at a human speed, so Lorentz contraction, aberration and Doppler shift happen at walking pace.
We need more tiny knowledge projects—here’s one
Crowdsourcing dynamic illustrations for a new astronomy book by Terry Tao and Tanya Klowden. The other day I was reading the sample chapter of a new book by Terence Tao and Tanya Klowden, on the so-called cosmic distance ladder. It’s a lovely piece of writing. The chapter tells the story of how Johannes Kepler, using data collected by Tycho Brahe, solved the puzzle of planetary motion. It puts us in the discoverers’ shoes: instead of working backwards from Kepler’s equations, we work forwards from the inexp
