A 1551 print of Ptolemy’s Almagest annotated by Galileo Galilei has been newly discovered in the Biblioteca Nazionale Centrale di Firenze! 🌙🔭🪐 #HistSci

Refined. Audacious. Philosophical to the core. I’ve just come out of a lecture by (my favorite philosophical voice today) @leaypi.bsky.social at Collège de France. And it left me wanting to read Hermann Cohen.

#HistMath & #PhilMath — here's the CfP you didn't know you needed! *FRAMING MATHEMATICS: EARLY CAREER WORKSHOP ON THE HISTORY AND PHILOSOPHY OF MATHEMATICS* Taking place at the Université Paris Cité on 10-11 September 2026. Full CfP in the poster. Please share! 🤝 @bernalessel.bsky.social 🤝

Congrats to new PhD Silvia Cerasaro, who last week defended her thesis at the Dept. of Mathematics, Tor Vergata (Rome)! She showed how history of math can support math teaching in primary school. Fibonacci on fractions was her case study. I advised her on the medieval side of the project.

Premodern Mathematical Thought is out! I'm so grateful to the brilliant contributors who trusted me as editor. Among them: Mancosu,Trifogli, Rommevaux, Majcherek, Robert, Di Liscia, Roudaut, Biard, De Risi, Clucas, Goddu, & myself. Time to show this gem some love! Thanks @degruyterbrill.bsky.social

Want to track recent publications on medieval (philosophy of) mathematics? @cleliacrialesi.bsky.social has you covered on the page below (which includes my *Medieval Finitism* as well):

New book added in Mathematicalia's hot off the press section. Do you want your book to feature in the list or know about a book that definitely deserves a spot there? Drop me a line! mathematicalia.com/newly-releas...

I’m visiting the Center for the History of Philosophy and Science at Radboud University. Very excited to get to know people that are the authors of some of my favorite studies!

My book is finally out and available at Routledge. Hope it adds (even just a little!) to our understanding of early medieval philosophy and mathematics.

Starting now! CARA Plenary on what's going on on campuses around the country to support Medieval Studies and the humanities. Join us online for this important panel discussion! #MAA2025 sites.harvard.edu/maacentennia...

@cleliacrialesi.bsky.social Hello Clelia, I wonder something and I think you could help me: How « droit » (ορθός or ευθύς) is defined in medieval Mathematics? And how does it differ from ancient Mathematics?

Did everyone know about @urochester.bsky.social "Admont Codex" except me? Because holy cabooses this manuscript is AMAZING! Musicological treatises written in Admont ca. 1200. Look at these music-theory diagrams! Can't wait to see it IRL later this month! urresearch.rochester.edu/institutiona...
