The author of Zero and Proofiness explains how to tell truth from fantasy in the digital world, and why it matters

Today, the Internet allows us to spread information faster and to more people than ever before?never mind whether it’s true or not. In Virtual Unreality, mathematician, science reporter, and journalist watchdog Charles Seife takes us deep into the information jungle and cuts a path through the trickery, fakery, and cyber skullduggery that the Internet enables. Providing a much-needed toolkit to help separate fact from fiction, Seife, with his trademark wit and skepticism, addresses the problems that face us every time we turn on our computers and Google our most recent medical symptoms, read a politician’s tweet, fact-check something on Wikipedia, or start an online relationship. Let the clicker beware.
