Introduction

Andy Murray, Molly Oldfield and Anna Chazinsky round up our favourite facts from the last seven days. We also have a special guest with us today, whose name is Mark Abrahams. For those of you who don't know him, Mark is the founder of the Ignebel Prizes. The prizes are given out every year for pieces of research that first make you laugh and then make you think. This year's probability prize went to a team of scientists for making two related discoveries.
