Welcome to (MC)2! The Mid-Cities Math Circle will have its first meeting of Spring 2026 on Wednesday, January 28, 2026, at 7:00 PM. All meetings this semester will be in person in PKH 311 (note the room change from Fall 2025).
The tentative schedule for the semester (Wednesdays at 7:00 PM) is:
1/28, 2/11, 3/4, 3/25, 4/8, 4/22
On March 25, we will have a special math circle lecture by Professor Edray Goins, Pomona College, and the next President of the Mathematical Association of America. The title and abstract of his talk are below.
Title: “A Survey of Diophantine Equations”
Abstract:
There are many beautiful identities involving positive integers. For example, Pythagoras knew 3² + 4² = 5², while Plato knew 3³ + 4³ + 5³ = 6³. Euler discovered 59⁴ + 158⁴ = 133⁴ + 134⁴, and even a famous story involving G. H. Hardy and Srinivasa Ramanujan involves 1³ + 12³ = 9³ + 10³. But how does one find such identities?
Around the third century, the Greek mathematician Diophantus of Alexandria introduced a systematic study of integer solutions to polynomial equations. In this talk, we will focus on various types of so-called Diophantine Equations, discussing such topics as Pythagorean Triples, Pell’s Equations, Elliptic Curves, and Fermat’s Last Theorem.
