    1. How to fold and cut a Christmas star<br /> Christian Lawson-Perfect https://www.youtube.com/watch?v=S90WPkgxvas

      What a great simple example with some interesting complexity.

      For teachers trying this with students, when one is done making some five pointed stars, the next questions a curious mathematician might ask are: how might I generalize this new knowledge to make a 6 pointed star? A 7 pointed star? a 1,729 pointed star? Is there a maximum number of points possible? Is there a minimum? Can any star be made without a cut? What happens if we make more than one cut? Are there certain numbers for which a star can't be made? Is there a relationship between the number of folds made and the number of points? What does all this have to do with our basic definition of what a paper star might look like? What other questions might we ask to extend this little idea of cutting paper stars?

      Recalling some results from my third grade origami days, based on the thickness of most standard office paper, a typical sheet of paper can only be folded in half at most 7 times. This number can go up a bit if the thickness of the paper is reduced, but having a maximum number of potential folds suggests there is an upper bound for how many points a star might have using this method of construction.

    1. This seems to have an interesting relation to the tradition of wassailers and "luck visitors" traditions or The Christmas Mummers (1858). The song We Wish You a Merry Christmas (Roud Folk Song Index #230 and #9681) from the English West Country (Cornwall) was popularized by Arthur Warrell (1883-1939) in 1935. It contains lyrics "We won't go until we get some" in relation to figgy pudding and seems very similar in form to Mari Lwyd songs used to gain access to people's homes and hospitality. An 1830's version of the song had a "cellar full of beer" within the lyrics.

      I'm curious if the Roud Folk Song Index includes any Welsh songs or translations that have similar links? Perhaps other folk song indices (Child Ballads?) may provide clues as well?

    1. I grew up in a small town called Surry on the coast of down-east Maine. At Christmas, most everyone in our town bought their trees at Jordan's Tree Farm. $5 per tree, cut at your own risk. Thinking back, it seems funny to me now, since after all, this is rural Maine, the pine tree state. And you'd think everyone could cut their own trees on their own land. And it's not like the trees at the Jordan farm were so special. Pretty much everyone called them Charlie Brown trees. People came because of Robert Jordan. They were loyal to him, and they figured he could use the money.

    1. "During Christmas, there's a log that you feed scraps of food, and then he poops presents when you hit him with a stick and sing a song!"

      I heard about this when I was in Barcelona last spring!
