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

Beautiful Madness: Math And Motherhood  Can You Have It All?, Abigail Wacher
Beautiful Madness: Math And Motherhood  Can You Have It All?, Abigail Wacher
Journal of Humanistic Mathematics
I am a tenuretrack assistant professor, and I have a beautiful threeyear 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 EarlyCareer Math Mama, Caitlin Krul
Don't Ask The Baby To Do Calculus: Thoughts From An EarlyCareer 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
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
On Contradiction, Piper Harron
Journal of Humanistic Mathematics
Parenting, across species, is a clumsy, allconsuming, 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 SimicMuller
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
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 nontenured 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.

The Situatedness Of Mathematics In Motherhood And Academia, Jennifer Schenk Sacco, Jill Shahverdian
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 decisionmaking 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
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 (cofounder of Project NExT). Without them, and others like them ...
Graceful Colorings And Connection In Graphs, Alexis D. Byers
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
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 wellmixed assumptions is used to describe the spatial and temporal changes in concentration. The resulting system of differential equations was solved by a RungeKutta 4 numerical method, which allowed for the addition of ...

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
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 eighthgrade mathematics classroom for student teaching with the mindset that I was going to tackle this challenge headon. 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 selfesteem, low selfconfidence 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 ...

Runs Of Identical Outcomes In A Sequence Of Bernoulli Trials, Matthew Riggle
Runs Of Identical Outcomes In A Sequence Of Bernoulli Trials, Matthew Riggle
Masters Theses & Specialist Projects
The Bernoulli distribution is a basic, wellstudied distribution in probability. In this thesis, we will consider repeated Bernoulli trials in order to study runs of identical outcomes. More formally, for t ∈ N, we let Xt ∼ Bernoulli(p), where p is the probability of success, q = 1 − p is the probability of failure, and all Xt are independent. Then Xt gives the outcome of the tth trial, which is 1 for success or 0 for failure. For n, m ∈ N, we define Tn to be the number of trials needed to first observe n consecutive successes (where the nth ...

Archimedes In The Classroom, Rachel Towne
Archimedes In The Classroom, Rachel Towne
Masters Essays
Eureka! Eureka! What better way to excite and engage students than to bring Archimedes into the classroom? Archimedes is widely regarded as the greatest mathematician of antiquity. Very little is known about Archimedes’ personal life. Archimedes was born in Syracuse, Sicily around 287 B.C., and he was the son of an astronomer. He probably studied in Alexandria, Egypt under followers of Euclid. Today we know Archimedes as a brilliant mathematician and scientist, he spent much of his career inventing war machines. Despite orders not to harm Archimedes, his life was cut short in 212 B.C. when the Romans ...

The Department of Defense (DoD) enlists multiple complex systems across each of their departments. Between the aging systems going through an overhaul and emerging new systems, quality assurance to complete the mission and secure the nation‘s objectives is an absolute necessity. The U.S. Air Force‘s increased interest in Remotely Piloted Aircraft (RPA) and the Space Warfighting domain are current examples of complex systems that must maintain high reliability and sustainability in order to complete missions moving forward. DoD systems continue to grow in complexity with an increasing number of components and parts in more complex arrangements. Bathtubshaped ...
I'Ve Got Your Number: A Multiple Choice Guessing Game, Ryan Cushman, Adam J. Hammett
I'Ve Got Your Number: A Multiple Choice Guessing Game, Ryan Cushman, Adam J. Hammett
Adam J. Hammett, Ph.D.
We consider the following guessing game: fix positive integers k, m, and n. Player A ("Ann") chooses a (uniformly) random integer from the set {1,2,3,...,n}, but does not reveal it to Player B ("Gus"). Gus then presents Ann with a koption multiple choice question about which number she chose, to which Ann responds truthfully. After m such questions have been asked, Gus must attempt to guess the number chosen by Ann. Gus wins if he guesses Ann's number. The purpose of this note is to find all canonical mquestion algorithms which maximize the probability of Gus ...
