### How Always to Win at Limbo

### or "You can sum some of the series some of the time, and some of the series none of the time...but can you sum some of the series all of the time?"

Remember in those early days of first-love how you would dream about that special someone and wonder to yourself: "How close are we?" This presentation will address this question by answering: What does it mean for two things to be close to one another? We'll take a strange look infinite series, dare to mention a calculus student's fantasy, and momentarily engage in transcendental meditation. In fact, we'll even attempt to build some very exotic series that can be used if you ever have to flee the country in a hurry: we'll either succeed or fail... you'll have to attend to find out. Will you be at the edge of your seat? Perhaps; but if not, then you'll probably fall asleep and either way, after the talk, you'll feel refreshed. No matter what, you'll learn a sneaky way always to win at Limbo.

This presentation is open to all math fans—young and old alike. A familiarity with infinite series is helpful. If you've ever head of the phrase "triangle inequality", then this lecture for you.

### Faculty of Mathematics Dean's Reception

**Dean's Reception:**

Stephen M. Watt, Dean of the Faculty of Mathematics invites UW Math alumni, friends and supporters to join him for a reception prior to the Pouliot Lecture to celebrate the exciting mathematics of the last 50 years at the University of Waterloo and how our faculty, alumni, and students are shaping the next 50 years of mathematics.

### Adrien Pouliot Lecture by Richard Hoshino

### Saturday, December 9th, 7:00 - 8:00 pm

### Mathematics 3, Room 1006

**Four Problem-solving strategies for Mathematics and for Life**

In this informal and interactive presentation, winner Richard Hoshino will present four of his favourite math problems, and share stories of how these problems have led to authentic mathematical experiences for both high school students and undergraduates. He will share his story through these four problems, which will simultaneously be accessible to high school students and challenge the math professors in the audience. In the process of solving these questions, we'll uncover four key problem-solving strategies that enable us to impact others, through our lives as mathematicians and educators.
