Dynamic Control Of Probabilistic Simple Temporal Networks, James C. Boerkoel Jr., Michael Gao, Lindsay Popowski

All HMC Faculty Publications and Research

The controllability of a temporal network is defined as an agent’s ability to navigate around the uncertainty in its schedule and is well-studied for certain networks of temporal constraints. However, many interesting real-world problems can be better represented as Probabilistic Simple Temporal Networks (PSTNs) in which the uncertain durations are represented using potentially-unbounded probability density functions. This can make it inherently impossible to control for all eventualities. In this paper, we propose two new dynamic controllability algorithms that attempt to maximize the likelihood of successfully executing a schedule within a PSTN. The first approach, which we call MIN-LOSS DC, finds …

Book Review: Prime Suspects: The Anatomy Of Integers And Permutations By Andrew Granville And Jennifer Granville, Paolo Mancosu

Journal of Humanistic Mathematics

Prime Suspects is a delightful graphic novel that performs what might, prima facie, seem almost like an impossible feat. Apart from the aesthetic pleasure it provides by being a well-illustrated and well thought out graphic novel, I would describe its major conceptual goal to be that of conveying to its reader a taste of the exciting nature of mathematical discovery. This is accomplished by focusing on a set of results connecting the study of prime numbers, the study of cycles of permutations, irreducible polynomials in finite fields and more.

Mathematical Conquerors, Unguru Polarity, And The Task Of History, Mikhail Katz

Journal of Humanistic Mathematics

I compare several approaches to the history of mathematics recently proposed by Blåsjö, Fraser–Schroter, Fried, and others. I argue that tools from both mathematics and history are essential for a meaningful history of the discipline.

In an extension of the Unguru–Weil controversy over the concept of geometric algebra, Michael Fried presents a case against both Andr ́e Weil the “privileged observer” and Pierre de Fermat the “mathematical conqueror.” Here I analyze Fried’s version of Unguru’s alleged polarity between a historian’s and a mathematician’s history. I identify some axioms of Friedian historiographic ideology, and propose a thought experiment to gauge its …

Simple Arithmetic: Heavy On Butter, Cream, Wine, Sarah Voss

Journal of Humanistic Mathematics

The User's Guide Project: Looking Back And Looking Forward, Don Larson, Kristen Mazur, David White, Carolyn Yarnall

Journal of Humanistic Mathematics

In 2014 Luke Wolcott created the User's Guide Project, in which a group of algebraic topologists came together to write user's guides to coincide with their research papers in hopes of making their research more accessible. We examine the role of this innovative project within the greater mathematics community. We discuss the structure and history of the project, its impact on the community, and its value to the participants of the project. We end by encouraging the math community to recognize the value of the project and expand the User's Guide Project to other subfields.

My Last Fermat’S Last Theorem Talk, Richard Delaware

Journal of Humanistic Mathematics

From the dangerous snowfall preceding and nearly ending it, to the pleasant years-long fallout afterward, I tell the story of the events surrounding my final presentation of an expository talk on Fermat’s Last Theorem in the same year but months before Andrew Wiles announced his proof.

My Sets Are My Foundation, Andres Sanchez

Journal of Humanistic Mathematics

You might be wondering, what the hell does set theory have to do with writing? I’ll tell you a secret:\ everything is built on sets. Sets are things of beauty. They are great ways to conceptualize, compartmentalize, and classify the world and everything it encompasses. And now I know I’ve danced around the question of what sets have to do with my writing. So, here is my answer: I use set theory as the foundation for all of my writing.

Tired: A Reflection On Asceticism And The Value Of Quantitative Assessment, Frances Dean

Journal of Humanistic Mathematics

I have spent a lot of time thinking this past year and a half about the relationship between asceticism and success. As a mathematics student and a collegiate athlete, I have far too often gotten caught up in the pursuit of objective standards. This chase has left me burnt out and broken. Existential philosophy has been my greatest asset in discerning the true purpose of asceticism. I reflect on this journey and the nature of assessment in this short reflection.

The Healing Powers Of Mathematics In The Age Of #Metoo, Veronica G. Sine

Journal of Humanistic Mathematics

The ideas of mathematics can provide metaphors to help people handle traumatic situations, or to better understand life experiences. In this short note, the author describes three ways in which the study of mathematics has given her ways to cope with her own difficult experiences.

On Not Teaching Addition: A Homeschooling Parent Teaches And Researches Math, Marion D. Cohen

Journal of Humanistic Mathematics

Interactions with the humans in one’s life can have bearings on the way one interacts with one’s work – and vice versa. In particular, the ways in which a math person who is also a parent interacts with their children can correlate with the ways that person interacts with students, colleagues, and with math itself. This article describes some of that correlation in one mathmom’s life. In particular, this mathmom worked toward balancing, both as a mom and as a teacher, her beliefs and feelings with societal mindsets and practices.

Tips For Undergraduate Research Supervisors, Stephan Ramon Garcia

Journal of Humanistic Mathematics

I was recently asked to contribute a paper to a forthcoming Foundations for Undergraduate Research in Mathematics (FURM) volume [1]. The article contained, in addition to several lengthy case studies, a list of brief recommendations for undergraduate research supervisors. Several colleagues suggested developing these general principles into a separate, self-contained article. This is that article.

Mathematical Cognition And The Arts, Marcel Danesi

Journal of Humanistic Mathematics

This article revisits the study of mathematics in the arts, and vice versa, the arts in mathematics, with a view to connecting mathematical and artistic creativity to the same neural circuits—a proposition put forward for mathematics and language in a critical 2000 book by Lakoff and Núñez, Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being. This expanded perspective would open up suggestive avenues for connecting mathematics, language, and the arts as part of an imaginative blend that comes out in different forms but having the same underlying neural source. Whether or not this can be …

Mathematical Possibilities In Modernism: Can Literature Be A System?, Arka Chattopadhyay

Journal of Humanistic Mathematics

From Aristotle’s Poetics, literature and logic have been companions in approaching the hypothetical realm of the ‘what if.’ In this paper, I focus on the combinatorial possibilities of logic to see how mathematics becomes an important tool for the Modernist text’s aesthetic appeal to anti-representational and self-enclosed systemic autonomy. Is mathematical discourse autonomous vis-à-vis external reality? Can literary Modernism achieve textual autonomy that goes against realistic verisimilitude by following mathematical discourse? Though literary texts often negotiate formal systems with sophisticated governing logics, can literature itself become a logico-mathematical system? I trace the dialectic of form and system in the …

Why Our Hand Is Not The Whole Deck: Embrace, Acceptance, Or Use Of Limitations, Robert S.D. Thomas

Journal of Humanistic Mathematics

I investigate with examples limitations that mathematicians accept in research: aesthetic, scientific, and practical, in particular, on what bases such choices are made. Discussion is partly in terms of the ideal agents that Philip Kitcher and Brian Rotman used to analyse mathematical writing.

Designing Fractal Line Pied-De-Poules: A Case Study In Algorithmic Design Mediating Between Culture And Fractal Mathematics, Loe M.G. Feijs

Journal of Humanistic Mathematics

Millions of people own and wear pied-de-poule (houndstooth) garments. The pattern has an intriguing basic figure and a typical set of symmetries. The origin of the pattern lies in a specific type of weaving. In this article I apply computational techniques to modernize this ancient decorative pattern. In particular I describe a way to enrich pied-de-poule with a fractal structure.

Although a first fractal line pied-de-poule was shown at Bridges 2015, a number of fundamental questions still remained. The following questions are addressed in this article: Does the original pied-de-poule appear as a limit case when the fractal structure is …

College Mathematics Students' Peceptions Of "Believing" Teacher Actions, Shelly Sheats Harkness, Bethany A. Noblitt

Journal of Humanistic Mathematics

Believing and doubting – two methodological processes – deserve equal attention according to Elbow (1986; 2006). When a teacher plays the doubting game in a mathematics classroom her own mathematical thinking dominates and she attempts to find flaws and errors and misconceptions in students’ mathematical thinking. When a teacher plays the believing game in a mathematics classroom she surrenders her own mathematical thinking and she attempts to find virtues and strengths and merits in students’ mathematical thinking. Paradoxically and succinctly, a teacher must believe her own mathematical thinking in order to doubt and a teacher must doubt her own mathematical …

Students Studying Students And Reasoning About Reasoning: A Qualitative Analysis, Salvatore J. Petrilli, Grant Clark, Nicholas Demarco, Jack Esposito, Brianne Giuliano, Sara Greiss, Emily Harris, Alessia Merritts, Kyle Murray, Mateusz Piekut, Brian Seidl, Scott Shannon, Nicole Silva, Christina Sullivan, Brittany Willoughby, Yile Zhou

Journal of Humanistic Mathematics

In this work, a faculty member takes a journey along with students as they enhance their understanding of how people solve mathematical problems through a mainly qualitative statistical project. Student authors of this paper registered for a problem solving seminar led by the faculty author, and then created and analyzed self-built assessment tools to explore problem solving techniques. Here we share our findings and recommendations, which we hope will inspire others to explore novel pedagogical techniques in the teaching of mathematical problem solving. We incorporate into our presentation ur voices, reflecting on how we and others solve problems.

From Carriage Wheels To Interest Rates: The Evolution Of Word Problems In Algebra Textbooks From 1901 To Today, Jemma Lorenat, Elodie Arbogast, Ethan Baer, Carla Condori Bazan, Robert Bettinger, Emily Carpenter, Hiawatha Davis Iii, Derick Grant, Olivia Howe, Neil Kelley, Maya Minier, Naima Orozco-Valdivia, Alan Peck, Carolina Saavedra, Sumesh Shiwakoty, Hunter Sidel, Carter Stripp, Josephine Terrien, Simone Wolynski, Leana Yearwood

Journal of Humanistic Mathematics

In teaching algebra, extra-mathematical word problems can bridge the gap between questions about abstract numbers and questions about everyday life. Thus, more than other aspects of elementary algebra, we would expect word problems to have changed in the recent past. This paper documents the findings of a collective research project that examined the content of such word problems over the past century. Alongside amusing and provocative examples, this paper shows how students can participate in exploratory research with primary sources from the history of mathematics.

The Mathematics Of The Astrolabe And Its History, Graziano Gentili, Luisa Simonutti, Daniele C. Struppa

Journal of Humanistic Mathematics

In this article we trace the scientific and cultural history of the astrolabe, a mechanical instrument used in the past for astronomical measurements and navigational purposes. The story of the astrolabe is interesting from several points of view, since it intertwines mathematical developments, geographical explorations, changing worldviews, and different cultures and civilizations. In our explorations we move from the early understanding of the world due to the Greeks, to the loss of their work, its rediscovery, the reception of Arab thinkers in Western natural philosophy, and, finally, to the new European culture that emerged with the end of the Middle …
