Mathematics hosts inaugural Ed Nelson Memorial Lecture March 20

The Mathematics Department will host alumna Gail Nelson, professor of mathematics at Carleton College in Northfield, Minn., for the inaugural “Ed Nelson Memorial Lecture Series,” at 3:30 p.m. Wednesday, March 20, in 114 Witmer Hall.

Refreshments will be served in the foyer outside of 114 Witmer Hall, starting at 3 p.m.

As part of her lecture, Nelson will discuss the “Magical Properties of Farey Sequences.”

What is a Farey sequence?  Take all the reduced fractions from 0 to 1 (inclusive) with denominators no larger than some maximum. Now arrange them in order of increasing value. And that’s a Farey sequence. And yet, from this very simple definition comes some amazing features.
