### Movie Night: The Proof

For over 350 years, some of the greatest minds of science struggled to prove what was known as Fermat's Last Theorem -- the idea that a certain simple equation had no solutions. Now hear from the man who spent seven years of his life cracking the problem, read the intriguing story of an 18th century woman mathematician who hid her identity in order to work on Fermat's Last Theorem, and demonstrate that a related equation, the Pythagorean Theorem, is true.

Andrew Wiles devoted much of his career to proving Fermat's Last Theorem, a challenge that perplexed the best minds in mathematics for 300 years. In 1993, he made front-page headlines when he announced a proof of the problem, but this was not the end of the story; an error in his calculation jeopardized his life's work. In this interview, Wiles recounts how he came to terms with the mistake, and eventually went on to achieve his life's ambition.

The department will show the movie on Thursday, December 1st at 7:30pm in Albright Auditorium. Refreshments will be provided. Bring your friends!

### Mathematical Models of Bone Biochemistry with Applications to the Treatment of Osteoporosis

On Wednesday, October 26th at 4:30pm in Napier 201 the Department of Mathematics and Computer Science will host Dr. David Ross of Rochester Institute of Technology. Dr. Ross is a SIAM Visiting Lecturer and will be giving a talk entitled: "Mathematical Models of Bone Biochemistry with Applications to the Treatment of Osteoporosis".

In humans and other mammals the skeleton is continuously remodeled, that is, dissolved and rebuilt; human bone has an annual turnover rate of about 10 percent. Understanding the biochemical processes of bone remodeling is important to the development of treatments for the disease osteoporosis, which is characterized by low bone mass, and which puts those who have it at risk of bone fractures. Osteoporosis results from an imbalance in the biochemical remodeling process, when resorption-the chemical breakdown of old bone-outstrips the formation of new bone. The most common cause of osteoporosis is age-related hormone change, the reduction of estrogen in women after menopause, and the reduction of testosterone in older men. Roughly 20 percent of women over the age of 50 have osteoporosis.

In this talk Professor Ross will discuss dynamical system models of bone remodeling that are used to simulate bone remodeling and to study the effects of various treatments for the condition. He will focus on the ways in which the dynamical systems capture the important biochemical features of the remodeling process, and he will discuss modeling methodology and the ways in which models are used. (Refreshments will be served beforehand.)

### Students Elected to Phi Beta Kappa

**ΦBK**(Phi Beta Kappa) is a national academic honor society, founded in 1776, and currently having chapters at 280 American colleges and universities. According to its web site, "Phi Beta Kappa celebrates and advocates excellence in the liberal arts and sciences. Its campus chapters invite for induction the most outstanding arts and sciences students at America's leading colleges and universities."

In 2011, the following mathematics students were selected by Zeta of New York, the HWS chapter of ΦΒΚ, for membership:

**Yaoxin Liu (H'12)****Jessica Tarantino (WS'12)****Sarah Tarantino (WS'12)**

It is noteworthy that all three students were elected to membership as Juniors, which is considered a singular honor.
