**2015 Richard Sady Prize: Yichao Li**

Each year the department presents the Richard Sady Prize to our best second year graduate student based on his/her performance in the basic courses he/she took in their first year. Richard Sady was a graduate student in our department and received his Ph.D. in Mathematics in 1977. He then was an assistant professor at Pembroke State University in North Carolina where he died in 1982. He was beloved by many here. This fund was established in his name.…

## Math for Everyone explores Newton's method

### February 26, 2015 • Categories: Announcements and Department Events

This past Thursday (Feb. 19) at the Math for Everyone lecture series, Jeffrey Diller, professor of mathematics at the University of Notre Dame, gave a presentation about imaginary numbers, unsolvable equations, and Newton’s method.

Diller opened his presentation by posing the question of what mathematicians do, one of which is to solve equations. He then delved into equations that are unsolvable, like non-linear equations. “When we can’t solve equations, we need methods to approximate solutions to equations,” said Diller.
