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.
Monthly Events: To see our event schedule and sign up for an event, check out our current events.

March 29, 6:00 - 7:45pm (Pizza at 6, presentation at 6:30)
~~~In-person with option to attend online~~~
Speaker: Dr. Dongho Lee (Dalhousie)
Topic: Definability and Games
Abstract: In this workshop, we will be looking into a question in Finite Model theory regarding definability.
Model theory is a branch of mathematical logic which studies the relationship between the formal theories and their models.
Finite Model Theory concerns, in particular, the models of the finite universe and it has nice relationships with database and complexity theory.
In the first part of the presentation, we will be introduced to an example of (first-order) theory and its (relational) model.
We will then ask what (Boolean) properties of models can be defined as a formula in first-order logic.
In the second part, Ehrenfeucht-Fraïssé Game will be introduced and we will see how Ehrenfeucht-Fraïssé theorem helps us show that
some properties are not definable in first-order logic.

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!
