Injustice, Inequity, and Inequality: Lessons at the Intersection of Mathematics, Epidemiology, and Racism
Nadia Abuelezam ’09 is presenting the 18th lecture in the The Michael E. Moody Lecture Series on “Injustice, Inequity, and Inequality: Lessons at the Intersection of Mathematics, Epidemiology, and Racism.”
Nadia N. Abuelezam, Sc.D. is an epidemiologist and assistant professor at the Connell School of Nursing. Dr. Abuelezam was trained in infectious disease epidemiology at the Harvard T.H. Chan School of Public Health. She graduated from Harvey Mudd College in 2009 with a B.S. in Mathematical Biology. She has expertise in mathematical modeling, data analytic approaches in public health, and mitigating health inequities for vulnerable populations. Her current research focuses on understanding health risks in hard to reach populations, including immigrants. The goals of her program of research are to use quantitative methods and novel data streams to better understand inequities in health outcomes and healthcare access in resource poor settings and vulnerable populations.
The COVID-19 pandemic has exposed existing health inequities for communities of color in the United States. Racism is a known structural cause of these health inequities. Counterfactuals are essential to our understanding of causal relationships in epidemiology, but how do you formulate a counterfactual for racism? This talk will explore the basis for counterfactual thinking in epidemiology and the ways in which we need to “re-imagine” counterfactuals to address one of society’s longest standing issues: racism.

For many, math is lifeless and meaningless; a bunch of rules to follow; a way to separate people rather than a way to bring them together. It’s no wonder that many have anxiety over their math experiences. I believe more people would love math if they could see how it is intimately tied to what it means to be a human being and live a more fully human life. I’ll explain how math can (or should) meet basic desires that all human beings share, and builds virtues that serve each person well no matter what they do in life. A prison inmate has helped me see this more clearly than ever before.

The lecture took place on February 20, 2019 at 7 p.m., in HMC‘s Shanahan Center Auditorium.
The maths in our everyday lives works quietly behind the scenes—until someone forgets to carry a 1 and a bridge collapses, a plane drops out of the sky or a building rocks when its resonant frequency matches a gym class leaping to Snap’s 1990 hit “I’ve Got The Power.” In addition to contemplating math in our everyday lives, Matt Parker will discuss his latest book Humble Pi, which explores what happens when maths goes wrong in the real world. Parker explores and explains a litany of near-misses and mishaps involving the internet, big data, elections, street signs, lotteries and the Roman empire and shows us the bizarre ways maths trips us all up, and what this reveals about its essential place in our world. We would all be better off, he argues, if we saw maths as a practical ally so we can use it to our advantage and learn from its pitfalls.

Play is essential for human flourishing. Whether you are a poet or a scientist, a grandparent or a child, play can powerfully enrich your life. For mathematicians, play is essential for building intuition. For undergraduates, play can inspire a desire to get involved in mathematical research. The world of knots provides fertile ground for understanding these connections. Playing games on knot diagrams can give us intuition about knotty structures, while learning about the theory of knots can reveal the “magic” behind rope tricks and excite us to learn more.

The lecture took place on March 30, 2017, at 7 p.m., in HMC‘s Shanahan Center Auditorium.
This talk will tell the story of how a journalist, two mathematicians, and a statistician teamed up and used mathematics to identify people who were using the lottery as an adjunct to their illicit activities. The analysis combined old and new mathematics with on-the-ground detective work. The resulting series of journal and newspaper articles led to arrests and changes in state policy, and contributed to the resignation of the head of the Florida lottery. Still, many questions remain to be investigated.

Societal inequalities pose some of the biggest and most intractable challenges facing our nation today. Can mathematical concepts help us understand and analyze social inequality? What is the relationship between various imbalances in the U.S. today such as those we see in income distribution and political polarization? This talk will explore answers to these questions. We will focus on a few quantitative approaches that mathematicians and political scientists use to measure inequalities. The metrics we will look at include the Gini Index for measuring income inequality, and the Roeck measure for detecting gerrymandering. We’ll also discuss how our political environment and policies can reduce or intensify inequalities in society.

The renaissance was a time when art and science were not polar opposites, but extensions of one another. With the advent of the enlightenment era, a dualistic tension between visual arts and scientific research was introduced. Today, the study of nature is serving as a bridge between these worlds once again. Heavily infused with imagery, we look at examples at the intersection of modern art and research mathematics, including architectural monuments inspired by the mysteries of honeycomb designs, paintings and visualizations motivated by the genetic data of novels, and paper sculptures spawned from the folding of leaves and proteins.S

“Who’s number one?” is an inherent and often debated question in sports. Ranking algorithms supply mathematical answers to such questions. They can and are used to choose teams for the playoffs. They can also be used in predictive analysis. Who will win the next game? Who will win a tournament? This talk will present current and recent sports analytics research. A variety of questions will be explored. For example, how can one integrate late season momentum? Does it help to consider home field advantage? We will see how such research created brackets for March Madness that beat over 90% of over 8 million brackets submitted to ESPN’s online tournament.

Cancer is the collective name given to an entire class of diseases characterized by rapid, uncontrolled cell growth. To ensure continued growth, tumors must acquire a continuous supply of nutrients and the ability to export metabolic waste. They accomplish this by recruiting new blood vessels from the nearby existing vasculature, a process known as tumor-induced angiogenesis. Angiogenesis is a critical bifurcation point in cancer progression as it provides the necessary blood supply for the growth of solid tumors beyond a few millimeters in diameter. The angiogenic cascade is an extremely complex, yet well-ordered series of events involving biochemical and biomechanical signals that operate across several temporal and spatial scales. In this talk, classical and current mathematical models of tumor angiogenesis will be explored and recent advances will be highlighted.

Positive sums count. Alternating sums match. So which is “easier” to consider mathematically? This talk is one part performance art and three parts combinatorics. The audience will judge a combinatorial competition between the competing techniques. Be prepared to explore a variety of positive and alternating sums involving binomial coefficients, Fibonacci numbers, and other beautiful combinatorial quantities. How are the terms in each sum concretely interpreted? What is being counted? What is being matched? Do alternating sums always give simpler results? You decide.

As with all of the college’s evening speaker lectures, the talk was aimed at a wide audience and was open to all.
If, as Galileo said, the book of the universe is written in the language of mathematics, it is also true that many new chapters in the book of mathematics have been inspired by nature. I will explore this connection through several puzzles from the ordinary experiences of everyday life: why is it difficult to break dry spaghetti in half? Why do things like extension cords, shoe laces, and earbuds always get tangled up in knots? How does a falling droplet splash onto the floor? In each case, careful experimentation leads to mathematical answers, generating interesting new questions in the process.

How do web-search algorithms work? Early algorithms just counted the number of times a query word appeared in a given webpage. More recent algorithms rely on “link analysis”, which aims to mine the collective wisdom encoded in the network of links: people make judgments about how useful a given page is for a given topic, and they express these judgments through the hyperlinks they choose to put on their own pages. I will show how linear algebra forms the common underpinning of three link-analysis algorithms for web search: PageRank, HITS, and SALSA. I will also discuss a modification of HITS that originated from a Mathematics Clinic at Harvey Mudd College, and is joint work with several people, including Harvey Mudd College undergraduates.
