Congratulations to the entire Williams College Math Team and to Professors Ralph Morrison (the coach of the team) and Steven Miller (the co-organizer of the competition)!

Many thanks to the Middlebury folks for coming down to Williams, and to all 18 Williams students who participated! We look forward to the Fall 2017 Green Chicken contest, to be held at Middlebury College.

The 2016 Green Chicken questions are available here, with solutions here.

]]>Imagine a SARS outbreak in quaint Williamstown – that’s exactly what Varun Bhadkamkar ’17, Anthony Brooks ’16, Jack Ferguson ’17, Connor Mulhall ’17, and Annie Sher ’17 did in their Math 307 final project. The SARS group built a network model of the Williams College undergraduate population, grouping individuals by dorms and dining halls, assuming that’s where the majority of transmission would take place. Using their model, they determined that one infected individual could lead to an all-out epidemic infecting nearly 97% of the undergraduate population if no intervention policies were implemented. Knowing that the Williams administration would never let the entire campus get infected, they went to look at various interventions and determined that those that reduce contact with infected individuals, such as wearing face masks, would be able to quell the epidemic. In total in Math 307 there were nine groups investigating nine separate diseases with a wide range of questions such as: can the anti-vaccination movement lead to re-emergence of measles in the US? How would response to government intervention affect the Ebola epidemic in West Africa? Is vaccination or treatment the best way to help lions infected with canine disease temper virus? Which part of the immune response will have the most impact on levels of mono? How should the government prioritize treatment in countries with high levels of TB? What drives the different dynamics of two similar STDs – syphilis and gonorrhea? And can new vaccines for malaria and dengue really lead to elimination?

The Doddceum celebration for Frank Morgan included live music by Scott Daniel ’17 and Jack Hood ’18, a six-foot life-size cutout of the guest of honor, a slide show with pictures of Frank Morgan and Dodd Neighborhood in action, a throwback to the viral “Dancing the Parkway” video, a speech by Karen Huan ’16, Dodd Neighborhood director and proud Mathematics major, lots of great food and delectable desserts.

As per Doddceum tradition, we closed with haikus:

*The last Doddceum*

*Frank Morgan on his way out?*

*Oh boy, what is life?*

-Naomi Francois ’17

*We’ll miss a loved man*

*One so dear and integral,*

*One who leaves a rift.*

*Gentle, masterful*

*Lord of the pretty bubbles,*

*Floats away as one.*

-Ali Tafreshi ’15

Seniors offered advice, including:

Blake Mackall: “Hard problems are good because you’re learning.”

Sarah Wu: “Get a tutor.”

Ben Kaufman: “Don’t write “clearly” or “obviously” unless you’re really sure.”

Matt Tarduno: “Don’t use PowerPoint for colloquium.”

Greg Ferland: “Keep a diary.”

Peter McDonald: “Thesis.”

Roger Vargas: “Limit use of beverage wrench.”

Jon Yin: “Don’t let school get in the way of your education.”

Katie Bennett: “Math is a great place to make friends.”

Next year’s 200 majors (102 rising juniors and 98 rising seniors) is an all-time record and makes us the second largest department at Williams after Economics (213).

Prof. Morgan thanked departing faculty Profs. Don Beaver, Satyan Devadoss, Eyvi Palsson, and Lauren Childs and welcomed Prof. Susan Loepp as new chair on her 20th anniversary at Williams. Prof. Loepp thanked Prof. Morgan for his service, presented him with a picture of his department family, and distributed signature soap bubbles to all:

Your favorite math problem/phenomenon/pretty graph or knot.

A great joke about math.

The longest amount of time you’ve ever spent on a problem set.

The time you were closest to quitting, and how you kept going.

Why math?

**An Unconventional Path **by Sarah Fleming ’17

For most of her life, Pam Harris had no plans to become a mathematician. Brought to the United States from Mexico at the age of eight, she had no prospects of attending university after graduating high school because of her immigration status. As she still wanted to continue her education, Pam began taking classes at Milwaukee Area Technical College, a community college near her home. She originally set out thinking she would become an art teacher because she had had several influential art teachers throughout her education. To complete her degree, though, she needed to take a math class, so she enrolled in college algebra. To her surprise, she enjoyed it so much that she decided to use her remaining elective credits to take trigonometry and three courses in calculus. She soon graduated from community college with associate degrees in art and science, and she longed for an opportunity to take more math courses.
