Sandor Szathmari's Kazohinia: Mathematics And The Platonic Idea, Susan J. Siggelakis Jan 2019

Sandor Szathmari's Kazohinia: Mathematics And The Platonic Idea, Susan J. Siggelakis

Journal of Humanistic Mathematics

In this article I analyse Sándor Szathmári’s utopian, satiric novel, The Voyage to Kazohinia, as an exercise in the portrayal of Platonist ideas. Through a discussion specifically of Szathmári’s portrayal of the way mathematics is conceived in two different, imaginary societies, I aim to reveal his preoccupation with exploring a solution to the essential political and moral problem of the alienation of interests between the individual and the group. This analysis locates Szathmari’s ideas within the Platonic tradition as well as within the context of 20th century philosophical ideas, particularly those of Georg Lukács. Szathmári’s ...


Extending Set Functors To Generalised Metric Spaces, Adriana Balan, Alexander Kurz, Jiří Velebil Jan 2019

Extending Set Functors To Generalised Metric Spaces, Adriana Balan, Alexander Kurz, Jiří Velebil

Mathematics, Physics, and Computer Science Faculty Articles and Research

For a commutative quantale V, the category V-cat can be perceived as a category of generalised metric spaces and non-expanding maps. We show that any type constructor T (formalised as an endofunctor on sets) can be extended in a canonical way to a type constructor TV on V-cat. The proof yields methods of explicitly calculating the extension in concrete examples, which cover well-known notions such as the Pompeiu-Hausdorff metric as well as new ones.

Conceptually, this allows us to to solve the same recursive domain equation X ≅ TX in different categories (such as sets and metric spaces) and we ...


Four Derivations Of Schrödinger’S Time Dependent Equation, Sydney Swanson Dec 2018

Four Derivations Of Schrödinger’S Time Dependent Equation, Sydney Swanson

Essential Studies UNDergraduate Showcase

Physics and the natural world have been studied by humans since the first person wondered ‘Why?’ The Schrödinger equation is important because it attempts to describe a relatively new (to us) and unfamiliar part of our universe, behavior of subatomic particles, and helps modern scientists uncover secrets that have proven useful in technology and explaining our origins. The time dependent Schrödinger equation can be derived from various starting points in Classical such as the equation of a wave, the time independent Schrödinger equation, and Hamilton-Jacobi equations. Why Quantum mechanics exists, useful applications, and cases when it fails or is inaccurate ...

Optimizing Maternal And Tenure Clocks: A Mathematical Proof, Tara T. Craig

Journal of Humanistic Mathematics

This essay shares my journey to solving the problem of timing, specifically as it applies to having a child on my journey towards a career as a mathematician in academia. I share some of the challenges I faced during pregnancy and the first few years of motherhood, which coincided with my first few years as an assistant professor of mathematics.


College Dropout To College Professor, Deborah L. Gochenaur, Rose I. Verbos Jul 2018

College Dropout To College Professor, Deborah L. Gochenaur, Rose I. Verbos

Journal of Humanistic Mathematics

Being a college dropout wasn’t something to be proud of; it just happened. Life doesn’t always turn out the way we want or expect. Yet, it is often how we deal with defeat that defines us – figuring out when to lick our wounds and when to come back fighting. It took a few years to redefine my dream, start a family, and seem to move forward, but the ache for more was always in the back of my mind. Could I succeed at something at which I had already failed? Going back to school at a community college ...


Rational Points On Surfaces And In Life, Amanda Knecht Jul 2018

Rational Points On Surfaces And In Life, Amanda Knecht

Journal of Humanistic Mathematics

Theses stories come from a mathematician who gave birth to two children while on the tenure track in an older department with only one tenured woman.


Beautiful Madness: Math And Motherhood --- Can You Have It All?, Abigail Wacher Jul 2018

Beautiful Madness: Math And Motherhood --- Can You Have It All?, Abigail Wacher

Journal of Humanistic Mathematics

I am a tenure-track assistant professor, and I have a beautiful three-year old boy and a husband who I love. My life today is within epsilon of the future I imagined while I was in university and contemplating a career in mathematics. Getting here, however, took longer than I thought. Along the way I often felt I was under pressure to choose between my career and having a family. I never made this choice and, although my pregnancy and my son did interfere with my career, I would not have it any other way. This is the story of how ...


Don't Ask The Baby To Do Calculus: Thoughts From An Early-Career Math Mama, Caitlin Krul Jul 2018

Don't Ask The Baby To Do Calculus: Thoughts From An Early-Career Math Mama, Caitlin Krul

Journal of Humanistic Mathematics

I very recently became a math mama. In my desperate search for patterns and structure in those first few weeks, my husband told me, "She's only three weeks old; we can't expect her to be doing calculus homework." I suppose he was right. I am working towards tenure and finding a new balance between teaching and family, all while trying to not lose sight of who I am. My personal challenges range from the logistics of being a nursing mother in a shared office to feelings of being seen as less adequate in my job if I present ...


So, Your Mom Wants To Be A Mathematician, Edie Stevens Jul 2018

So, Your Mom Wants To Be A Mathematician, Edie Stevens

Journal of Humanistic Mathematics

Despite all the stereotypes about them, mothers possess a skill set that makes them outstanding potential mathematicians. Most are organized, detail oriented, driven, determined, effective communicators; they are able to break down any concept or task into its principal components, and they can be logical and persuasive even when addressing the most formidable and unwilling audience. In short, no matter how messy, difficult, or tedious the task at hand, moms excel at getting the job done. This is my affirming story of how I left my engineering career to raise a family and returned to academia to pursue a doctoral ...


On Contradiction, Piper Harron Jul 2018

On Contradiction, Piper Harron

Journal of Humanistic Mathematics

Parenting, across species, is a clumsy, all-consuming, and often exasperating endeavor. Yet in many parts of the human world, we somehow expect to contain and control this part of ourselves. We idealize the separation of work and family. This seems to be especially true in mathematics where many of us hold space in our minds for the Devoted Genius Mathematician who has no other responsibilities but to their own passions, and no obstacles beyond the difficulties of their own pursuits. The unavoidable fact is that life with children is full of absurdities and contradictions. Unless we're willing to embrace ...


Motherhood And Teaching: Radical Care, Ksenija Simic-Muller Jul 2018

Motherhood And Teaching: Radical Care, Ksenija Simic-Muller

Journal of Humanistic Mathematics

This essay is a personal reflection on how I leverage my positioning as a caregiver in my roles of a mathematician, teacher, and mother, to advance a vision for a more just and equitable society. I argue that care at home and in the classroom takes similar forms, and can be liberating instead of oppressive


From Ecstasy To Agony And Back: Mathematics, Motherhood, And Postpartum Depression, Azadeh Rafizadeh Jul 2018

From Ecstasy To Agony And Back: Mathematics, Motherhood, And Postpartum Depression, Azadeh Rafizadeh

Journal of Humanistic Mathematics

In this essay I address some challenges I had to overcome as a non-tenured mathematician mother married to another mathematician. While some of these challenges, such as lack of sleep, were predictable, many were not. For example, I was not aware that just getting pregnant would be a difficulty. Also, I did not know how paralyzing postpartum depression could be. Looking back on these experiences after a few years, I have a new perspective. I share my experiences, feelings about them, and some of the ways I figured out to overcome the hardships I experienced.

For us, the intersections of literature and mathematics inspired many of our pivotal moments.


The Situatedness Of Mathematics In Motherhood And Academia, Jennifer Schenk Sacco, Jill Shahverdian Jul 2018

The Situatedness Of Mathematics In Motherhood And Academia, Jennifer Schenk Sacco, Jill Shahverdian

Journal of Humanistic Mathematics

The authors, a mathematician and a political scientist, examine mathematics, motherhood, and academia, and argue that feminist epistemology is necessary to explain the intersection. Relying on the principles of feminist epistemology laid out by philosophers Naomi Scheman and Marianne Janack, the authors consider how work, the concept of time, teaching, arts and crafts, and decision-making all reveal the situatedness of knowing and using mathematics.

Founders, Feminists, And A Fascist -- Some Notable Women In The Missouri Section Of The Maa, Leon M. Hall Jun 2018

Founders, Feminists, And A Fascist -- Some Notable Women In The Missouri Section Of The Maa, Leon M. Hall

Leon M. Hall

In the history of the Missouri Section of the MAA, some of the more interesting people who influenced the growth and development of the section through the years were and are women. In this chapter, we discuss the contributions of a few (certainly not all) of these women to the Missouri Section and mathematics as a whole, including Emily Kathryn Wyant (founder of KME), Margaret F. Willerding (who dealt with sexism in the 1940s), Maria Castellani (an official in Mussolini’s Italy before coming to America), and T. Christine Stevens (co-founder of Project NExT). Without them, and others like them ...


Graceful Colorings And Connection In Graphs, Alexis D. Byers Jun 2018

Graceful Colorings And Connection In Graphs, Alexis D. Byers

Dissertations

For a graph G of size m, a graceful labeling of G is an injective function f : V (G)

{0, 1, . . . , m} that gives rise to a bijective function f 1 : E(G) {1, 2, . . . , m} defined by f 1(uv) = |f (u) f (v)|. A graph is graceful if it has a graceful labeling. Over the years, a number of variations of graceful labelings have been introduced, some of which have been described in terms of colorings.

A proper (vertex) coloring of a graph G is an assignment of colors to the vertices of G such that adjacent vertices ...

Mathematical Modelling Of English Coulee: Tanks In Series, Matthew Picklo May 2018

Mathematical Modelling Of English Coulee: Tanks In Series, Matthew Picklo

Essential Studies UNDergraduate Showcase

In the scope of the College of Arts and Science project: “Coulee Cleanway: Modelling and Analysis of the English Coulee Physiochemical Environment, UND Campus, Grand Forks”, a mathematical model attempting to describe the transportation of dissolved species within the English Coulee was developed based on “Tanks in Series”. By dividing the channel into discrete regions, a governing system of equations derived from conservation of mass equations and well-mixed assumptions is used to describe the spatial and temporal changes in concentration. The resulting system of differential equations was solved by a Runge-Kutta 4 numerical method, which allowed for the addition of ...


The Pope's Rhinoceros And Quantum Mechanics, Michael Gulas Apr 2018

The Pope's Rhinoceros And Quantum Mechanics, Michael Gulas

Honors Projects

In this project, I unravel various mathematical milestones and relate them to the human experience. I show and explain the solution to the Tautochrone, a popular variation on the Brachistochrone, which details a major battle between Leibniz and Newton for the title of inventor of Calculus. One way to solve the Tautochrone is using Laplace Transforms; in this project I expound on common functions that get transformed and how those can be used to solve the Tautochrone. I then connect the solution of the Tautochrone to clock making. From this understanding of clocks, I examine mankind’s understanding of time ...


Transforming Students Through Geometric Transformations, Sierra Galicia Apr 2018

Transforming Students Through Geometric Transformations, Sierra Galicia

Honors Theses AY 17/18

It is a common saying among teachers that the hardest grades to teach are middle school. Beginning January 3rd, 2018, I was placed in an eighth-grade mathematics classroom for student teaching with the mindset that I was going to tackle this challenge head-on. I started the experience enthusiastic and ready to teach my students with exciting and engaging lessons. Unfortunately, I soon found that many students have low self-esteem, low self-confidence and they lack the necessary perseverance needed to complete challenging assignments and to be successful in math. It quickly became apparent why people say middle school is the hardest ...
