Saturday March 22, 2014 – Recurrence Relations and Celtic Knots

Title: Recurrence Relations

Lecture Notes: Recurrence_relations

Speaker: Andy Loo

Abstract: In counting problems, sometimes it is hard to count the total number of configurations directly, but if we look at the problem from a different angle, we may be able to find connections with the number of configurations in smaller cases. The question then is how to get the total number from these recurrence relations. Let’s find out this weekend!

Title: The Math of Celtic Knots

Leaders: Justin Lanier & Harini Subrahmanyam Fredrickson

Time & Date: 3:14pm-4pm, Saturday March 22

Location: Princeton Public Library, teen room (3rd floor)

Abstract: It’s St. Patrick’s Day this week! We’ll look at some ornate Celtic knots, observe and explain some patterns, and make some knot drawings of our own. We’ll also discuss the difference between knots and links, ways to identify each, and some other basic topological ideas. Come shamrock some great math with us!
