Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: From unequal growth of polycrystalline grains to unequal e-commmerce markets
Abstract: Many curious problems in Materials Science seem simple at first but they require complex mathematical models to explain. One of such problems is evolution of grain structure in polycrystalline materials or foams. Each grain in 3D has many faces in which it shares a grain boundary with other grains. In a polycrystalline materials neighboring grains compete for space and bigger grains grow at the expense of their smaller neighbours. This dynamics is easy to formulate in two dimension but much more complex in three dimensional reality. This talk presents application of phase field models for large scale simulation of grain growth. We will then discuss how to analyze the results and explain the growth process.

The talk then detours to considering interesting societal dynamics that resemble materials science problems. For example, the revenue that merchants generate in a given market presents a similar dynamics where in the market competition, few bigger sellers dominate the space at the expense of smaller ones.
