There is no Nobel Prize in mathematics. Find out how you can still earn yourself one if you are a mathematician. Featuring Gale and Shapley's stable marriage theorem and and the debunking of a popular sex statistics myth.

In my life before YouTube I together with my colleague and friend Marty Ross used to write a math column for the AGE newspaper in Melbourne. We covered the topics that feature in this article in two articles in 2008. Check them out:
