The 11th annual Princeton University Mathematics Competition is barely a month away! As one of the largest math competitions for high school students in the world, we attract hundreds of students to Princeton to engage in a day-long adventure in mathematics. The main website for the event is here.

As a student-run event, we are always looking for volunteers to help out!

**Date:** November 19th (Saturday)

**Time:** 9 am – noon, but we would also appreciate extra volunteers for the afternoon

**Role:** Proctoring

**Perks:** FREE (yummy) breakfast, FREE (catered) lunch, FREE (sexy) t-shirt

If you are interested in helping out, you can contact ypatel@princeton.edu. Additionally, if you are interested in helping test-solve, you can contact eneyman@princeton.edu.

You may have heard of *Hamlet *by William Shakespeare. BUT have you heard of *Ham-set *by Jerry Shakespeare? Jerry Shakespeare, who looks resounding similar to his brother and also apparently had very similar dialogue in his stories, is a newly discovered gem. Come discover the newly uncovered, six-hundred year old manuscript in its truest form **this Tuesday**!

**Who**: Prof. Jerry Wang

**What**: To Square or Not to Square

**When**: 5:00 PM — 6:00 PM, Tuesday, 10/18

**Where**: Fine 110

Abstract: I will be speaking about my two research areas on rational points on hyperelliptic curves and squarefree sieve of discriminants.

Welcome back to campus! Hope everyone had a great summer.

We will be having a colloquium this coming Wednesday at 5 pm in Fine 214. The speaker will be Prof. Gang Tian who specializes in geometric analysis. Check out his profile/wikipedia page here: http://en.wikipedia.org/wiki/Gang_Tian

The title of the talk will be “Conic spherical metrics”. Here is the abstract:

I will discuss the problem of constructing spherical structures on 2-sphere with prescribed conic angles and its connection to geometric stability. In the end, I will briefly discuss higher dimensional analogue of this problem.

Hope to see you there!

The next colloquium will be this coming Monday, 4/28, given by Prof. Yakov Sinai. It will be at 5pm in Fine 322. He will be talking about deterministic chaos and here is the abstract:

Deterministic chaos is a property of deterministic dynamics. I shall explain main properties of chaotic dynamics and give some example of chaotic dynamical systems.

Prof. Sinai is known for his work in dynamic systems. As many of you may have heard, he received the Abel Prize, which is often described as the mathematician’s Nobel Prize, not long ago. Check out his wikipedia page if you are interested!http://en.wikipedia.org/wiki/Yakov_Sinai
