Random walks in the park

When this year’s Perimeter Scholars International students were tasked with finding interesting physics in Waterloo Park, three students opted to cast a wider net.

Rather than exploring some of the phenomena in the park next door to Perimeter Institute — the light dancing on the lake, the wind moving through the trees — Katie Latimer, Mohamed Hibat Allah, and Matija Medvidović decided to put “random walk” models to a literal test.

As they explain in the video, random walk models aren’t just useful for working out how to get back to their apartments. They apply in a wide number of scenarios, from finance to biology.



The class of 26 Perimeter Scholars International graduates gathered in their homes around the world for their online convocation, which featured surprise addresses from three Nobel laureates in physics.
