We take another look at algorithms. Tim Hwang explains how Uber’s algorithms generate phantom cars and marketplace mirages. And we revisit our conversation with personal.umich.edu/%7Ecsandvig/">Christian Sandvig who, last year asked Facebook users to explain how they imagine the Edgerank algorithm works (this is the algorithm that powers Facebook’s news feed). Sandvig discovered that most of his subjects had no idea there even was an algorithm at work. Plus  James Essinger and Suw Charman-Anderson, tell us about Ada Lovelace, the woman who wrote the first computer program (or as James puts it – Algorithm)  in 1843.
