Rosemarie Emanuele

"Math Geek Mom"

Although she holds a Ph.D. in economics from Boston College, Rosemarie Emanuele is a professor and the chair of the Department of Mathematics at Ursuline College in Pepper Pike, Ohio, just outside of Cleveland. She loves to teach math but also pursues research related to the economics of nonprofit organizations and volunteer labor, and has published in both economics and interdisciplinary journals — as well as in the book that inspired this blog. She is the proud mother of a wonderful daughter.

As I age, my eyes are staring to betray me. This is something that I particularly notice when I am reading things that involve superscripts or subscripts, which occurs often in math and economics.

An important topic from Algebra is that of intersecting lines. Equations can be written representing lines on graph paper, and Algebra, especially Linear Algebra, helps find points that are contained on more than one line, where two or more lines intersect. I thought of this last weekend as I watched former students walk across a stage to receive their diplomas, and realized that their lives had intersected with mine. I know that my life is richer for having known them.

One of the concepts I teach in my Quantitative Reasoning class is the idea of “Exponential Growth.” Such growth, where a variable grows by a fixed percent, is found in such things as population growth and the growth of money earning interest. I found myself thinking of this recently as I watch my daughter grow at a rate that seems to be exponential, outgrowing clothes almost before they can be worn and threatening to soon pass me by in terms of height. I am thrilled to see her turning into a healthy young lady, but I have to pause as I realize that, as she grows, she is exposed to aspects of life that I would prefer to shield her from.

Central to the subject of Economics is the idea of “utility maximization.” This concept proposes that people choose the optimal assortment of work, goods and leisure given the constraints they face. As calculus is applied to compute such choices, it is assumed that the economic agent is strictly self-interested, an assumption I find myself thinking about as we celebrate Mother’s Day this weekend.

In economics, we talk about purchasing machinery that is used in producing a product as “investment”  in capital, and in acquiring skills and experience that will help an employee perform a job more efficiently as “human capital investment.” It is this later type of investment that seems to be on the forefront of the minds of many of my fellow parents who I run into lately.

One of the topics I teach in my Quantitative Reasoning class is the calculation of a retirement savings goal. It is always shocking to my students how much money they will need to save in order to live comfortably in their retirement. However, as daunting as the goal may seem, I emphasize that it is important to begin to put some of what we earn away into a safe fund so we can draw on it in the future, when we need it. I found myself thinking of this concept recently when I attended a track meet in which my daughter and her young friends competed. I had to laugh when she asked me after her meet "did you like to run when you were a kid, too, mom?"

When people learn that I am both a full professor of Mathematics and an Economist who studies the economics of nonprofit organizations, they are often confused. “What do you teach?” is the common question that follows, to which there is a quick answer, a short answer and a long answer.

Thanks to my daughter and her friends, I have been exposed to the computer game “Angry Birds.” In it, some nasty pigs try to steal the eggs of a group of birds. These birds then fight back by flinging themselves (with our help) in an attempt to destroy the pigs, who sit laughing at the whole matter. I am most intrigued by the fact that much of what I learned in my first college physics class can be put to use to progress through the game.

In statistics, we often talk of "outliers," observations that appear so far from the average that they teach us something about the underlying data and how they came to be. This is a concept that has gained attention recently as the month of March has so far distinguished itself as a true outlier in this part of the country.

I often laugh at the politics of taking coffee from a shared coffee maker. The person who takes the last cup needs to make a new pot, so no one wants to be the person to take that last serving. To avoid this, people often take only half of a cup, leaving a half of a cup for the next (and presumably last) person. This can go on for a while, and could, in theory, go on indefinitely, as dividing by two with each thirsty but lazy person will never actually result in an empty coffee maker.
