Math Circles events at Dal during the 2019/2020 school year
Below is our tentative schedule for the 2019/2020 school year. Events' timing is from 6:30-8:30pm. Halifax campus events will be held in the Chase Building, Room 119 (Student Learning Centre) of Dalhousie University. Truro campus events' location will be announced before the event and it may vary each time. In each event, pizza and pop will be served.
These workshops are appropriate for senior high and advanced junior high students.

Speaker: Dr. Peter Selinger
Topic: Fun with slide rules
The slide rule, based on an invention by John Napier in the
17th century, was the most important calculation tool for scientists
and engineers for almost 350 years. It was still in widespread use in
the 1950s and 1960s, but disappeared almost completely after it was
replaced by the electronic calculator in the 1970s. In this math
circle, you will learn how to use a slide rule to compute
multiplications, divisions, roots, powers, and other operations. You
will also learn some of the theory behind how a slide rule works. Each
participant will assemble their own working slide rule out of
materials that will be provided.
Speaker: Dr. Keith Taylor
Topic: Cardinal Sins of the InfiniteThe concept of infinity has fascinated people since ancient times. In this math circle, we will carry out a number of activities that naturally involve infinity in some manner. From a practical problem of stacking blocks with maximum overhang off a supporting edge to a totally impractical supernatural tale about a Genie and his pets, we will explore the sometimes surprising consequences of processes repeated infinitely often. Participants should be prepared to do a little arithmetic and some algebra.
Speaker: Sarah Meng Li
Topic: Logic and Puzzles
Math is not just computation. Mathematical thinking is a way of observing and understanding the world. Math allows us to see hidden order in real world chaos. This workshop will introduce you to another aspect of Mathematics, logic. We will show you how to use mathematical thinking to solve problems, identify the hidden patterns, and think like a mathematician.
In the first part of the workshop, we will talk about the fundamental building block in mathematics, namely set theory. There will be a buffet of set puzzles for you to investigate sets. We will use Venn diagrams to understand operations on sets and use these diagrams to solve puzzles.
In the second part of the workshop, we will play with logic! Logic is a systematic way of thinking that allows us to parse the meanings of sentences and to deduce new information from old information. We will use logic to distinguish Truth Tellers from Liars, and use logical inferences to play Werewolves.
Speaker: Erick Lee (HRCE)
Topic: Prime Time!
In this session we’ll be exploring prime numbers. Do you know to quickly find all the prime numbers from 1 to 100? Do you know why prime numbers are important in computer security? We’ll answer these questions as well as tackle some prime number problems, puzzles and games in a fun and engaging session.
