Science on Tap is a science lecture series where you can sit back, enjoy a pint, and laugh while you learn. Listen to experts talk about the science in your neighborhood and around the world. You don’t have to be a science geek to have fun—all you need is a thirst for knowledge!

We’re told that digital is better than analog, but have you ever wondered why your cell phone sometimes drops calls? Mathematician Greg Landweber studies applications of error correcting codes, that is, ways of encoding digital information so that garbled signals can still be decoded. He will introduce several examples of error detection and correction, as well as discuss the limits of these codes. Not a math person? Never fear! Using logic, hands-on activities, and a geometrical decoding machine of his own design, Landweber will explain how and why digital communication works.
