Why Pandora Won’t Rewind

Why can't you rewind or replay a song on Pandora.com? And when you type in the name of a song you want to hear, why will a different (but, yes, similar) song start to play instead? Argh, it's so annoying! But, it turns out, it's also the reason why the Web site can play those songs for free as a Webcaster. In the final installment of our latest Brains and Beakers series, Pandora's Tim Westergren devles into some of the nitty gritty of Web radio, a technology that, in his words, "just blew up." Previously: Brains & Beakers: The DNA of Your Favorite Songs - Part 1 Brains and Beakers: Inventors and Explosions! [Updated!] B&BII: Behind the Scenes of a How-To Machine About Brains & Beakers With support from the National Science Foundation, Youth Radio wants to change the way young people think about science--and scientists. What better way to do that than to make science a media event? Youth Radio joined forces with David Pescovitz from the website Boing Boing and the Institute for the Future to invite a stellar line-up of inventors, engineers, and investigators to our studios in Oakland, Calif. For each segment in the series, our guests provide interactive hands-on demos and then take questions from Youth Radio interviewers.
