Aperiodvent, Day 13: Fold-and-Cut Christmas Tree

The fold and cut theorem, which states that, after sufficient folding, any shape made of straight lines can be cut out of a piece of paper in one cut, is probably the most crafts-friendly result in all of maths.  Inspired by The Aperiodical’s very own Katie Steckles’ video on the subject, Sam Hartburn has created a handy PDF with instructions for folding and cutting a festive Christmas tree shape.

Aperiodvent, Day 10: Dimensional Analysis and Turkeys

Photo of Jim ProppBefore he entered Aperiodical’s Big Internet Math-Off, contestant Jim Propp wrote this lovely blog post about dimensional analysis back in February, using it to predict how well Michael Jordan would be able to play basketball on the moon and how long it would take to roast a large bird. Make use of it when you’re planning Christmas dinner!
