September 20, 2021

We celebrate the greatest scientific awards night, the 31st Ig Nobel Prizes. In this multi part special we find out about the history of the Ig Nobel prizes and some of the more well known examples from storied history. Who came home with the top prize this year in the Ig Nobel's? How can you navigate a crowd safely? What's the best way to model a busy train station? Does using a phone make it harder to navigate a crowd safely? Do people coordinate and work together to make through a rush hour crowd? Does a crowd self organise into lanes to navigate a busy intersection?
