FAMUS

The “Friday Afternoon Mathematics Undergraduate Seminar” (FAMUS) is a weekly event consisting of announcements, talks, and faculty interviews. FAMUS takes place most Fridays at 3:00-4:00pm in Room 164 of the Adel Mathematics Building. Typically the first half of FAMUS consists of a talk on a mathematical topic while an interview of a faculty member takes place in the second half. FAMUS is hosted by Jeff Rushall.

Come join us for some entertaining talks! Refreshments always served.

Schedule Fall 2017

Note that talks are listed in reverse chronological order.

Gauss’ Circle Problem

Date: September 22, 2017

Speaker: Jeff Rushall (NAU)

Abstract: This talk focuses on a famous puzzle first investigated by Gauss: counting the number of integer lattice points that lie inside a circle of radius “r” centered at the origin. Much is known about this problem, but there are still some unanswered questions involving the preciseness of the formulas used for estimating the number of such points.

The faculty guest this week is Dr. Dana Ernst. [PDF of Flyer]

Fermat Primes

Date: September 15, 2017

Speaker: Jeff Rushall (NAU)

Abstract: I will talk explain a curious piece of mathematical history - namely, the discovery of a special set of prime numbers that are now known as Fermat primes - and what their discoverer, Pierre de Fermat, got right and what he got wrong. I will also explain why Fermat primes are still interesting today.

The faculty guest this week is Dr. Terry Crites, who is our current department chair. [PDF of Flyer]

What did I do this summer?

Date: September 8, 2017

Speaker: Jeff Rushall (NAU)

Abstract: I will talk about the math I did, the traveling I did (to some semi-exotic places), and show you some really neat pictures (involving both math and traveling).

The faculty guest this week is Amy Rushall, who (among many other very important things) happens to be the new Academic Director of the Lumberjack Math Center. [PDF of Flyer]
