SciFriday: Computer Algorithms Rule the World

Your world is defined by the information you receive. More and more, complex mathematical formulas are shaping your reality, from detecting skin cancers to suggesting new Facebook friends, deciding who gets a job, how police resources are deployed, who gets insurance at what cost, who is on a “no fly” list — or what qualifies as “real” news.

Thanks to John Sudbury for this week’s SCIENCE. And congratulations to Austin Richardson for being the winner of our 2016 SCIENCE! contest! His prize package will be in the mail early next week.
