Real-Life Uses of Math

I know what you're doing.

You are staring at your feet and thinking, "Gee, I wish I had a list of 60 different ways to lace up my shoes."

Well, as I am ever eager to fill those voids in your life, I direct you to Ian's Shoelace Site, a site by a guy named Ian dedicated to showing you all about shoelaces. ("Fun, fashion & science in this quirky site about shoelaces. Whether you want to learn to lace shoes, tie shoelaces, stop shoelaces from coming undone, calculate shoelace lengths or even repair aglets, Ian's Shoelace Site has the answer!")

The mathy bits:

• Ian has a list of formulas to help you figure out how long your laces need to be for a given type of lacing.
• Ian also suggests that in certain shoes, there may be as many as two trillion different lacing methods!
