The Department of Sciences and Mathematics hosted the 2026 Sonia Kovalevsky Day on Friday, Oct. 23.

Dr. Sarah Poiani introducing Sonia Kovalevesky Day.

Sonia Kovalevsky was an outstanding 19th century mathematician and the first woman to receive a doctoral degree in mathematics. Every year, universities around the country honor her with a day-long session of mathematics activities, workshops, and competitions for high school students interested in mathematics.

Students started the day with a calculator-free math competition, consisting of 35 math problems. The top scorers in the competition were announced at the end of the day.

Then there was a keynote address from Dr. Phil Kains, who talked about what it means to be a “math person”. Dr Kains is assistant professor of mathematics at Bellhaven University.

After that, students broke out into small-group sessions on math and math-related topics led by W faculty. There were six small-group sessions to choose from, and each student did three of the six.

The small group sessions had students learning and doing activities in topics ranging from “Tavern Games and the Discovery of Probability” (Dr. Nora Corrigan), “The Mathematics of Voting” (Dr. Sarah Poiani), “The Fabric of Reality — Gravity, Space, and Time” (Dr. Josh Hanes), “Testing Hypothesis With Dice” (Dr. Travis Hagey) and others.
