The Improbable Research Collection videos are three-minute videos about research that makes people laugh, then makes them think. Each collection — each episode — is about three minutes long, composed of bits and pieces and people from the magazine Annals of Improbable Research, from Ig Nobel Prize lectures and ceremonies and other live events, and from many other sources. We have been collecting this material for almost twenty years. The format, roughly speaking, is similar to Monty Python. But the content is all real. Mostly, it's about science, technology, and medicine. And people. Each little episode is composed of several different threads, which may or may not be related. Some threads, and some people, recur in later episodes. Some do not.
