Welcome to NS Math Circles!

Nova Scotia Math Circles is dedicated to enriching the experiences of Nova Scotia students in all areas of mathematics.

Our program vision is to foster enthusiasm for math through interactive, creative, and meaningful presentations.

We offer monthly events at Dalhousie for senior high and advanced junior high students, and visit schools all across the province for free.

As we navigate challenges posed by the Covid-19 pandemic, we are actively following the guidelines and recommendations as outlined by Dalhousie University and the public health authorities in Nova Scotia. We regrettably will be suspending all of our in-person activities till further notice. We are, however, resuming activities virtually.

Virtual Classroom Visits: We are happy to offer virtual classroom visits, via Google Meet and Zoom.

Monthly Events: Our previous virtual monthly events are listed HERE. Monthly events will resume in the fall, so check back in September!

June 9, 7:00 - 8:35pm
Speakers: Sarah Li and Mozhgan Saeidi (Dalhousie)

Topic: Problem Solving with Algorithms

Abstract: An algorithm is a series of step-by-step instructions to carry out a task or solve a problem. For example, a cake recipe is an algorithm to make a cake. At school, you have learned algorithms such as the procedures for adding, subtracting, multiplying, and dividing numbers. You could also observe more algorithms in everyday life!

Beyond just solving a problem, we always hope to optimize ways to get to the answers. Algorithmic thinking allows us to resolve a problem creatively, and math helps us design efficient algorithms. In this workshop, you will see some interesting and well-known problems about graph coloring, numbers, and computing. Then we will navigate the algorithmic approach to tackle these problems!

Tentative itinerary:

  • Divide-and-conquer algorithm
    • Four-colourability of the world map [7:00 ~ 7:30]
    • Circular maximum sum subarray problem. [7:30 ~ 7:45]
  • Euclidean algorithm
    • Continued fractions [7:45 ~ 8:00]
  • Karatsuba's algorithm
    • Multiplication of integers [8:00 ~ 8:20]
    • Lattice multiplication [8:20 ~ 8: 35]

Thank you Eastlink for renewing your Half-Million Dollar Donation!!!

On June 17th, 2014 we announced a partnership with Eastlink. They donated $500,000 to NS Math Circles for the program to further expand its outreach into junior high schools and begin outreach in the elementary schools. In the spring of 2019, Eastlink renewed its $500,000 donation for a further five years, allowing us to continue our outreach, improve our program, and widen our scope. Thank You to Lee Bragg and Eastlink for these generous donations!
