sPad of Super Accuracy and Geometry in Old Babylon. -- sPad de S\'uper Exactitud y Geometr\'ia en la Antigua Babilonia

Abstract

Recently it has been discovered that on a stone tablet over 3800 years old, the Plimpton-322 table, are carved the geometric relations that exist between the sides of 15 right triangles chosen in a very special way. Due to its property as a super accuracy calculation tool, in this work we have called it sPad by stone pad, and we have calculated its machine accuracy $\epsilon_m$. Additionally, we present the physical and astrophysical constants most used in science and engineering in sexagesimal base. ----- Reci\'entemente se ha descubierto que en una tableta de piedra de m\'as de 3800 a\~nos de antig\"uedad, la Tabla Plimpton 322, est\'an ta\-lla\-das las relaciones geom\'etricas que existen entre los lados de 15 tri\'angulos rect\'angulos escogidos de manera muy especial. Debido a su propiedad como herramienta de c\'alculo s\'uper preciso, en este trabajo la hemos llamado sPad por \emph{stone pad}, y hemos calculado su exactitud de m\'aquina $\epsilon_{m}$. Adicionalmente presentamos las constantes f\'isicas y astrof\'isicas m\'as usadas en ciencia e ingenier\'ia en base sexagesimal.

Perspectives on the unit distance problem

This is a survey on an old open problem in combinatorics called the unit distance problem, and the field of mathematics around it, called incidence geometry. What do we know about the problem? Why is it difficult? How does it connect with other parts of math?

A Categorical Approach to Euclidean Ratios and Proportions

A categorial approach to the non-metric geometry in Books V and VI of Euclid's \textit{Elements} is presented. Specifically, we introduce a diagrammatic syntax that can be overlaid immediately on his diagrams, thus bridging intuitive presentation with fidelity to Euclid's arguments. This syntax makes complicated definitions like V.5, and indeed the arguments throughout books V and VI, including arguments about similar figures, intuitively clear. We show in an appendix that this syntax can be used to solve a puzzle regarding ancient mathematics. Finally, we offer evidence that this approach to Euclidean diagrams is rooted in the Aristotelian tradition itself, and that a similar syntax was utilized, in antiquity, for related questions of numeric and proportions. Thus the syntax is plausibly faithful to Euclid's own thought-world, and not an outside-imposition.

Some Early Results by Tutte Regarding the Cycle Double Cover Conjecture in 1948

OpenAI recently announced a proof of the Cycle Double Cover (CDC) Conjecture. Most media reports have characterized it as a 50-year-old open problem. In reality, according to a 1987 letter from Tutte to Fleischner, the Cycle Double Cover Problem has been open for at least 80 years. Two early results regarding the CDC conjecture were established in one of Tutte's 1949 publications.
