Dr Sarah Griffin of Lambeth Palace Library describes their experiences with a workshop that introduced children to medieval folded calendars
Zigzag Calendars: A case study in outreach with schools at Lambeth Palace Library
Dr Sarah M. Griffin, Curator of Unfolding Time: The Medieval Pocket Calendar From February to May 2025, Lambeth Palace Library hosted Unfolding Time: The Medieval Pocket Calendar.[1] The exhibition brought together a rare and remarkable type of medieval folded book for the first time—the concertina-fold almanac—and set them alongside treasures from Lambeth’s own collection. Folded in a zigzag pattern to form a neat, easily transportable packet of information, their playful form is emphasised by their colourful and almost entirely pictorial content, all of which relates to time.

My mom and stepdad are from the same diaspora group as Zohran Mamdani’s dad (same like “my stepdad was kicked out of the same town and knows some of his classmates”) and apparently the New York Times doesn’t understand how diaspora works, so I am going to tell you a little about my mom’s people!

Friends, for my final program at LHL on May 22, I will be joined by @hillemmalouise.bsky.social to discuss what happened after the burning of 300 copies of John Flamsteed’s 1712 Historia coelestis. Register here: events.lindahall.org/afterhourswi... #HistSci 📜 📚 #histSTM #astronomy #histastro 🗃️🔭
After Hours with Flamsteed's Burned Star Atlas
This program will be presented virtually via Zoom webinar.In 1716, British astronomer John Flamsteed built a pyre near the Royal Observatory. On it, he burned pages from a book he wrote as a “sacrifice to truth.” The pages were from the 1712 edition of Flamsteed’s Historiae coelestis, which Isaac Newton and Edmund Halley had printed despite Flamsteed’s vehement objections. What happened after the fire? How did copies of Historiae coelestis spread, and who circulated them? Not all the offending pages went up in flames. Flamsteed kept a few copies of the objectionable sections. In one copy, recently acquired by the Linda Hall Library, Flamsteed and his assistant took pen to paper in pursuit of truth: striking through, crossing out, and annotating Newton and Halley’s mistakes. Join scholar Emma Hill and the Library’s Vice President for Special Collections and Public Services Jason W. Dean as they introduce Hill’s census of surviving copies and discuss how the census has uncovered new information about the book’s production and the human story surrounding it.

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.
