ZOE XIAO, Wellesley Junior studying math and economics
Major: Mathematics, Economics College/Employer: Wellesley College Year of Graduation: Not available. 

Brief Biographical Sketch:
Although I am a math and econ major, I have many other interests that I pursue in my free time. This summer would be a great opportunity to teach and share them with others. I'm thinking of teaching linguistics, or something music/artrelated. I am also thinking about teaching number theory.

Number Theory and Other Random Math
What’s a recurrence? And why does it help with algorithms? If I have n newts, t toads, and s slugs, how many ways can I make n+t+s people miserable by putting my animals in their beds? In number theory, we will learn about the properties of numbers, in particular, integers. We will learn about how to effectively determine whether an integer is prime or not, how to prove the sqr root of 2 is irrational. We also learn a bit of cryptology—using numbers encoding messsages. You will be sending secret messages and ask people to decipher them. Learn about encryption, probability, induction, and other random topics in math. Great for students who want to learn a different kind of math than the kinds taught in high school.
