Carnival of Mathematics #39

by

The Carnival is here again! Celebrate the nearing end of August by visiting the 39th Carnival of Mathematics over at It’s the Thought that Counts, a blog by A and Z about “politics, society, science, morality, religion, and whatever else comes to mind”. (One post of theirs from earlier this month that I particularly enjoyed: Gallons per mile, which examined whether miles per gallon is the most appropriate way to measure a car’s efficiency.)

Returning to the carnival, this edition features a neat problem about the number 39 (If 39 people are sitting around a circular table and no one is in the correct place, prove that there is some rotation with at least two people in the correct place. Only they said it with more storytelling flair.), and a great collection of other posts. Enjoy!
