14 March 18

The date 3-14 is always Pi Day! Even though I'm not going to work today (on Spring Break) I must circle up and wear this new tie, tumbling the Greek letter π around and around. I've tied it with the Van Wijk knot, where you wrap the tie three times and then push the main part through, making approximately 3.14 spirals. I couldn't resist including a pie plate for my photo.
