Abstract

Ever wonder why some cicadas only come out every 13 or 17 years? Or why stock charts are usually plot the stock price on log scale? And why entropy is always defined with that natural log thing? In this light talk, we will take a few moments to explore an eclectic collection of "fun" facts and observations from the real world and beyond which have simple mathematical explanations. Topics may vary. Audience participation is strongly encouraged.
