Nine Algorithms That Changed the Future: The Ingenious Ideas That Drive Today's Computers

Synopsis

Nine revolutionary algorithms that power our computers and smartphones every day, we use our computers to perform remarkable feats. A simple web search picks out a handful of relevant needles from the world's biggest haystack. Uploading a photo to facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers, and we use digital signatures to verify the identity of the websites we visit.
