MESSAGE FROM MAA PRESIDENT 64 for improving the alignment between undergraduate training and careers. By focusing 2019 our work on pressing issues — mathematics for societal relevance — we can collectively Letter From help our students understand the importance of mathematics, not only in their Board of professions but across their lives. Directors MAA believes that collaboration through community is crucial to support this evolution Leadership which is why we invested in an online platform called MAA Connect. The platform is for our 28,000+ members to build communities around common interests such as our SIGMAAs (special interest groups) or Sections (geographic area), post discussions, and share resources. Our community has a critical role to play in this progression. Community support and collaboration is essential as we see more professional niches emerge from Michael Dorff Dear Friends, mathematical sciences such as fields of data science — yes, the plural is intentional. President As we learned through our engagement with the National Academies’ Roundtable on When the MAA was founded in 1915, what constituted Postsecondary Data Science Education, there are diverse incarnations of data science mathematical literacy and mathematical readiness was much across all sectors of the science, business, and government. Regardless of where and Deanna Haunsperger different than now. We live in a mathematics-enriched world Past-President in what form we encounter data science, mathematics has critical tools and insights to where we have hundreds of interactions, if not thousands, on offer. To address the strong need for faculty professional development, we have organized a daily basis. Moments we take for granted such as waking data science workshops that will be held this summer at two NSF-funded mathematics Carol Schumacher up to an alarm, navigating with GPS, or asking a smart device institutes.

Cincinnati, OH. It focused on community to allow a space for our members to network, attend informal sessions, and participate in activities. There were 8 member engagement events including a presentation by Art Benjamin, PosterFest,

and a long-term member reception. The MAA Pavilion uniquely supports those events that may not fit the category of “Invited Address” or “Contributed Paper Session” to provide an informal space for member gatherings.

1st MAA Math Summer Camp in Puerto Rico 1st MAA Math Program Designed for

The Dolciani Mathematics Enrichment Indigenous Communities in Washington State Grant program created the first MAA math summer camp — for middle and high school students— Puerto Rico Math Olympiads (OMPR). It is a five day summer camp hosted at the University of Puerto Rico at Mayaguez, directed by Professor Luis Caceres. In 2019, over 20 students participated where they learned problem solving strategies, enhanced their leadership skills, and further developed their love for mathematics.

The Tensor-SUMMA Grant program funded a teacher workshop and a two-week summer “OMPR is a place that really challenges camp, which was part of the Washington Mirror Program of Navajo Nation Math Circles led by Dr. David Auckly. This MAA program is the first of its kind in Washington State. It me, something that does not happen with is designed to reach Washington’s indigenous communities, as indigenous people are severely under-represented in the field of mathematics. The camp provided students my math classes at school. I love the fact from the Yakima Valley, an isolated area with a 60% Indigenous (comprised of several tribes), 30% Hispanic, and 10% other population, with opportunities to learn and explore that it encourages us to improve.” mathematics. Due to location and family responsibilities, most of these students would be unable to attend mathematics camps elsewhere even if they were offered.

Recent lawsuits alleging gerrymandering in Wisconsin, Maryland, and North Carolina have also caught the nation’s attention. The efficiency gap formula made headlines for the key role it played, particularly in the ongoing Wisconsin case. Since the introduction of this formula in 2014, the mathematics has moved forward more quickly than the courts, with alternative versions proposed, analyzed, and compared.

This generative artwork was created from the output of a simulated annealing algorithm designed to find the maximum independent set in a random graph. This problem is NP-hard, so simulated annealing attacks the problem by continually trying to improve its solution while occasionally accepting a worse solution in hopes of avoiding locally maximal solutions. The arc lengths of the colorful sectors behind the central tree structure are linked to how successful the solutions accepted by the algorithm are in solving the problem, starting at the twelve o’clock position and moving clockwise.

The Maryam Mirzakhani Prize is given to the top- scoring female from the AMC 10A, receiving $5,000. The five top-scoring females from the AMC 10A from each of MAA’s 29 sections will receive the Maryam Mirzakhani AMC 10 certificates in honor of their performance.

The award is named after Maryam Mirzakhani, an Iranian mathematician and previous professor of mathematics at Stanford University. She was the first woman to be honored with the Fields Medal, setting a strong example for many female students to follow their dreams to pursue mathematics.

Honorees included teams from the following: 8th Annual European Girls’ Mathematical DID YOU KNOW? Olympiad, 48th Annual United States of America Mathematical Olympiad, and 2019 United States of America International Mathematical Olympiad Team. Research by the Girl Scout Research Institute shows that girls start losing interest in math and science during middle school.

When I was younger, I thought it would be great to prove some famous math theorem like the Riemann Hypothesis or the Goldbach Conjecture; maybe even have a theorem named after me. To this date, I haven’t solved those problems and the “Dorff Theorem” does not currently exist. Now having more years of experience, solving a famous math problem is not what matters most to me. On the one hand, it would be an enormous accomplishment. On the other, as I reflect on my life, I realized what matters most to me is people.

For the past year, I have had the honor of serving as MAA President. I am not going to dive deep into the specifics of the many things MAA has to offer, as you have probably read it in this annual report already. However, I will answer a question for you. Why become a member of the MAA? My answer is simple. Join MAA for the community--the people. Members, donors, staff, students, volunteers, and everyone involved, are all driving forces behind MAA. They elevate MAA’s mission to advance the understanding of mathematics and its impact on our world.

Before I was MAA’s President, I was a member for many years. In those years, I have shared experiences, struggles, and ideas with people all across the world in the math community. Experiencing a sense of community was achieved by engaging myself in the many channels MAA offers to its members. I joined the MAA Intermountain Section, attended national committees, and volunteered for MAA projects, all of which have impacted my career. The diverse community of people’s expertise, in various mathematical areas, inspired great discussions that promoted positive changes in many areas such as: teaching, mentoring, researching, serving, and being more inclusive. Although we shared different mathematical areas of expertise, we shared the commonality for the love of mathematics. Those same people, who started as a community of colleagues, turned into lifelong friends.

It is the people, all of us, that is the strength of the MAA. I am grateful for the opportunities and friendships garnered through the MAA. Perhaps my work on solving an important math theorem is not the standard theorem you would find in a mathematics research paper. Instead, it is a theorem proven through the work we do in aiding the MAA, the mathematics community, and the general public with advancing the understanding of mathematics and its impact on our world.
