Why, it's another episode of #themathematicianspod this time an interview episode with the fabulous @[email protected], author of #themathrmaticianslibrary. Listen in to hear his thoughts on writing a book about books about maths. As well as more history and philosophy. #talkingmaths #mathsky

Episode 55 - Injective - Thomas K Briggs - On The Mathematicians' Library

In this special book club episode of 'The Mathematicians Podcast', I sit down with author, maths communicator, and museum learning consultant, Thomas K. Briggs. Join us for a glass of wine and a deep dive into Tom's book, 'The Mathematicians Library', a title so intriguing it was a must-have for the show. This 'Injectives' sub-series episode is a one-to-one conversation; today exploring the vast history of mathematical literature. Discover the oldest book in Tom's personal collection and unravel the criteria for what truly constitutes a "book of mathematics". Tom paints a vivid picture of ancient mathematical works, describing the evolution of writing media before the age of flat sheets and ink. The discussion navigates through the emergence of authorship in the Mediterranean, Indian, and Chinese traditions, and Tom shares his favourite example of a significant mathematical work without a known author. He also recounts the fascinating journey of a particular mathematical text through the ages, a story of translation and transcription that has preserved ancient knowledge. In a new segment of "Desert Island Codex," Tom reveals which ancient mathematical document he would choose to study in solitude and which ancient lecture he would love to have heard.  Moving beyond the book, the episode looks into Tom's work as a museum consultant. He sheds light on the origins of encryption and the methods ancient leaders used to send secret messages. The discussion also explores the vast, untranslated collection of Babylonian tablets and what they might still reveal about Mesopotamian mathematical understanding. Finally, Tom offers his own insightful, pithy definition of what mathematics truly is. He also reveals which mathematician he is most excited to see featured on a future episode of the podcast. Tune in for a captivating conversation that journeys through the annals of mathematical history, from ancient texts to modern museum exhibits.   You can find Ben on Bluesky @mathematicians-pod.

Here's a short post I made about #LaTeX and #Accessibility regarding the #ADA Title II requirements for course materials. #MathSky #AcademicSky #Science #EduSky

Accessibility for LaTeX-Based Teaching

On April 24, 2026, we are required as educators to comply with the new ADA Title II standards which adhere to Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. I regularly prepare mathematical and physics-heavy teaching materials using GitHub, Overleaf, and LaTeX. Because these documents often contain substantial mathematical notation, accessibility requires some extra care.
