International Conference: Beyond Books: Instruments and Knowledge in Libraries, Musée d’histoire des sciences, Geneva

Nowadays, most library users are unaware that for centuries, libraries have combined written and ‘hands–on’ dimensions of knowledge by collecting instruments and objects of all kinds.

In the Middle Ages, library collections frequently included astrolabes, quadrants, and sundials alongside treatises explaining their construction and use. Theories of libraries in the Renaissance already anticipated the inclusion of ‘mathematical instruments’. With the emergence of curiosity cabinets, between the 16th and 18th centuries the array of objects was continuously extended. Libraries acquired more and more maps, portraits, coins, medals, natural specimens, models, and exotic artefacts intended to engage with and enrich the libraries’ vast encyclopaedic knowledge.

The presence of a cabinet and the interaction between instruments and books became a crucial material and epistemological concern in the management of libraries, whether private or ‘public’, from the 17th century onwards.

Objects were stored close to books, or in adjoining rooms, and fulfilled various functions. Instruments were regarded as both ornaments and complements to written knowledge, three-dimensional representations of knowledge that could be handled. They therefore played a crucial role in understanding scientific texts, serving as examples or as mnemotechnic tools.

With the exception of a few studies, the presence of instruments in libraries has received little attention in the general history of libraries. The history of education, reading practices, architecture and institutions have taken precedence. The international conference Beyond Books: Instruments and Knowledge in Libraries aims to re-evaluate these historiographical assessments and reconnect libraries, instruments, and books. In a deliberately multidisciplinary and diachronic approach, the event will interrogate the acquisition, status and use of instruments in libraries across different time periods, geographical areas, and knowledge cultures.

Proposals of 300 words max. — in French or English — should be sent to Rossella Baldi and Samuel Gessner. The deadline for submissions is 15th June 2025.

Philadelphia Area Seminar on the History of Mathematics (PASHoM), Villanova University

\(\textcolor{green}{\text{This event is hybrid (in-person and online)}}.\)

The PASHoM seminar meets both in person and virtually on Zoom, with one speaker per month each semester. In the January talk Anna Englesone, Villanova University, will present WIlliam Sealy Gosset. All seminar talks will begin at 6:30 pm ET.

William Sealy Gosset (1876 - 1937) was a statistician, a chemist and -- according to Ronald Fisher, who had few good things to say about anyone’s intelligence apart from his own -- one of the most original thinkers of his time. A prolific scholar, Gosset published all his work under a pseudonym because his employer, the Guinness Brewing Company, did not want their brewers to divulge company secrets. In this talk, we will discuss some of Gosset’s important contributions to statistics, such as his work on experimental design, his contributions to the theory of statistical significance and his discovery of the Student T distribution that forms the basis of many statistical tests. We will also speak of William Sealy Gosset the person -- husband, father, friend, colleague, someone remembered for his kindness, his joie de vivre and his unconventional ways.

The TRIUMPHS Society has planned some exciting activities for its members in 2026. Foremost among these, we are launching a members-only Primary Source Virtual Reading Group (VRG). The VRG will meet quarterly (in January, April, July and October) with each Friday-Saturday session to include two 2-hour components: Friday afternoon/evening (6–8pm ET) and Saturday morning (11am–1pm ET). Sessions will be designed to work through texts that are not very well-known but speak to core mathematical ideas.

This inaugural session of the Society’s Primary Source VRG is hosted by Dominic Klyve and Danny Otero. The topic will be either “Euclid’s Elements, Book II,” or Archimedes’ “The Sand Reckoner.”

Philadelphia Area Seminar on the History of Mathematics (PASHoM), Villanova University

\(\textcolor{blue}{\text{This event will be online only.}}\)

The PASHoM seminar meets both in person and virtually on Zoom, with one speaker per month each semester. In the January talk Cliff Landesman, PhD, will speak on Leibniz’s Nova Methodus Pro Maximus et Minimus. All seminar talks will begin at 6:30 pm ET.

Leibniz’s Nova Methodus Pro Maximus et Minimus was the first paper to systematically introduce the method of differentials to problems in mathematics. Dirk Struik comments that this work “opens the modern period in the history of the calculus.” Leibniz presented the idea of the differential, gave the basic rules for differentiation and worked through several examples. He first did a routine but lengthy exercise in the algorithmic use of the rules, then gave a derivation of Snell’s law, treated the slope of curves in a class of generalized ellipses, and finally presented the solution to a problem posed by De Baune to Descartes. This last problem had remained unsolved for nearly fifty years. The determination of maxima and minima following the setting of a differential to \(0\) is discussed in general.

The series of online talks from the History of Mathematics Special Interest Group of the Mathematical Association continues with Dwight Anderson Williams II, Morgan State University, whose talk, is titled Navigating mathematical and political structures (Navigating MAPS): A perspective on the works of Black researchers in theoretical mathematics. will begin at 3:00 PM Eastern Time.

Abstract: This talk is a reflection on the influence of Black mathematicians and their works (including the 1980 book titled the same) in shaping my present/early career as a research mathematician. The impact of primary sources, cited stories, and personal communication is gauged by three themes: institutional memory, subversion, and point-of-contact. The talk also features contributions by Black mathematicians toward promoting, progressing and preserving mathematical ideas central to my professional development, current research in the representation theory of Lie superalgebras, and dissemination of mathematics to graduate students.

HOM SIGMAA Virtual Speaker Series

The series of online talks from the History of Mathematics Special Interest Group of the Mathematical Association continues with Colette Chilton-Carr, of Florida Atlantic University, whose talk, is titled An Overview of the Usage of Ancient and Contemporary Vigesimal Numeral Systems will begin at 3:00 PM Eastern Time.

Abstract: The modern base-10 decimal system originated during the 1st to 4th century A.D. and remains in place for most cultures. From the 3rd century B.C.E through the 17th Century A.D., the Maya had multiple ways of representing their numerals, one of which is the vigesimal system. In the mid 1990s, the vigesimal system was revamped by a contemporary group of marginalized mathematicians, and is still in use and being researched by universities to this day, but not without facing backlash. This presentation will include the historical context of the vigesimal numeral system within the Pre-Classic, Classic, and Post-Classic Maya periods, the contemporary vigesimal numeral system, and examples of how to perform arithmetic through both of these methods.

The PASHoM seminar meets both in person and virtually on Zoom, with one speaker per month each semester. In the April talk Dr. Julian Gould, University of Pennsylvania,, will speak on Zeno’s Paradox of Measure. All seminar talks will begin at 6:30 pm ET.

If a line segment is made up of points, and each point has no length, how can the line segment itself have length? Does this amount to an inequality of the form \(0 + 0 + \cdots{} \gt{} 0\text{?}\) As a paradox about counterintuitive features of summation, this puzzle is unsurprisingly attributed to Zeno of Elea. In this talk, I will discuss three different interpretations of the paradox. First, I will present the classical resolution due to Grünbaum, which essentially turns on the fact that Zeno had no concept of uncountable sets. Second, I will discuss recent work of Reese, Vazquez, and Weinstein, which reframes the issue in terms of Borel’s proof of compactness for the closed interval. Finally, I will offer some thoughts of my own, centered on the following ridiculous question: was Ockham a categorical homotopy theorist?
