What is computer science?
When people think of computer science, they think of IT staff, pocket protectors, incomprehensible letter sequences, and machines that crash at a moment's notice. But the truth is that if you've used a cell phone, made a Google search, bought something on Amazon (or anywhere else), downloaded an IPhone app, seen a Pixar movie, added a friend on Facebook, watched something on Hulu, twittered, or recommended a movie on Netflix, you've been part of the computer science revolution.
