Check out the new HLFF Blog article by Katie Steckles on some interesting mathematical concepts underlying the hanging of a picture.

Imagine you are hanging a picture on the wall. What if we wanted to be able to hang the picture so that, as soon as any single nail is removed, it falls off the wall? This might not feel like a particularly mathematical topic – but of course, there is some more advanced mathematics hiding in there. The idea of passing a string over a nail or wrapping it around the nail in a more complicated pattern can be described mathematically. To find out how, have a look at the full article here:
