History of Astronomy

Share-A-Thon!  

We're kicking off the year with a "Bring Your Own Reading" Share-a-thon.  What history of astronomy material have you been reading lately?  Primary sources?  Research articles?  Books?  Come prepared to tell us about it and share a link or citation!  

Due to illness, we've had to postpone Gabriela Rădulescu's session related to Soviet and Armenian astronomy for a future date.  Instead we will have a session following up on the recent History of Science Society meeting, with a couple presenters sharing their talks and those who attended discussing what topics and themes they found interesting at the conference. 

Presenting Talks (list will be updated as we get confirmations): 

• Beatrice Honey Steele, University of Exeter, "How a Brigade can Tackle an Eclipse": Norman Lockyer, the Royal Navy, and the 1900 Eclipse Expedition 

• Jeffrey Kotyk, Max Planck Institute for the History of Science (MPIWG), The Lunar Apogee and Nodes in Premodern East Asian Astronomy

No need for any reading in advance, but if you want to see what was happening at the HSS meeting, you can check out the program here: https://hssonline.org/resource/resmgr/annual_meeting/2025_new_orleans/2025_print_program_10_10.pdf

Education and Intersecting Populations in the History of Astronomy

With complementary goals in the establishment, circulation, and expansion of knowledge, the histories of science and education are strongly interrelated.  While astronomy has long been carried out in connection with educational goals and institutions, in recent centuries education has played an especially important role in mediating the intersection of different populations within astronomy: the public, the professional, the amateur, the enthusiast, the artisan, the worker, the popularizer, etc.  Educational philosophies and pedagogical theories have both influenced and been influenced by new understandings of what science is, what it does, who participates in it, and who it is for.  

Sarah Reynolds will give a brief presentation on her work-in-progress on the interaction between science and education in history, then lead discussion on two articles from a recent book that demonstrate such interactions in the case of Eise Eisinga, the 18th-century Dutch wool manufacturer and merchant who constructed an elaborate functional orrery on the ceiling of his home.

Narratives on the Marginalization of Astrology

For our first discussion, we will be looking at two articles on the marginalization of astrology. When, how, and why did astrology go from being considered a viable knowledge system to a pseudo-science? Recent work has revisited this question, providing an overview of different factors for astrology’s marginalization and showing how explanations have moved from an emphasis on intellectual factors to social/institutional influences and back again. This will be the first meeting of our working group, so please come prepared to briefly introduce yourself and what brings you to the group!
