July 30, 2019: Lecture on the *Epitome Almagesti*, Kansas City, MO

Henry Zepeda (Wyoming Catholic College) presents a talk, “The Apex of Ptolemaic Astronomy: The *Epitome Almagesti* of Peurbach and Regiomontanus”, at 3-4 pm CDT in Linda Hall Library, situated on the Volker Campus of the Univ. of Missouri-Kansas City. The *Epytoma in Almagestum Ptolemei*, a reworking of Ptolemy’s astronomical masterpiece the *Almagest*, was written in the early 1460s by Georg Peurbach and Johannes Regiomontanus, two of the most important figures of 15th-century astronomy. The copy held by the Linda Hall Library was printed in Venice in 1496. While it built upon earlier medieval commentaries on the *Almagest*, the *Epitome Almagesti* (as it is usually called) is remarkable for its depth of comprehension of even the most technical aspects of Ptolemy’s astronomy, its clear explanations, and its incorporation of new discoveries made by its authors and by Arabic astronomers. This work, which had circulated in manuscript form for 35 years before it was printed, became the textbook by which students of astronomy learned the intricacies of Ptolemy’s geocentric astronomy. In his writings challenging the Ptolemaic system, Copernicus often referred to this book, which contained proofs that were fundamental to his development of a heliocentric system. Dr. Zepeda recounts the drama-filled story of how and why this book was written and discusses its contents, sources, and influence. The event is free and open to the public; however, e-tickets are required at Eventbrite. Those unable to attend the lecture in person can watch a live broadcast from the Library’s Facebook page or via Livestream.

August 8, 2019: Lecture on Analog Computing in History, Kansas City, MO

Corey Maley (Assoc. Prof. of Philosophy, Univ. of Kansas) presents a talk, “Analog Computation in a Digital World: Understanding the Place of a Bygone Technology in Contemporary Science”, at 7-8 pm CDT in Linda Hall Library, situated on the Volker Campus of the Univ. of Missouri-Kansas City. Analog computers were once the dominant computing machines in engineering and science but have now been almost completely replaced by digital computers. While there are practical reasons for preferring digital computers over analog, there are theoretical reasons to rehabilitate our understanding of analog computation. Neuroscientists and cognitive scientists, for example, routinely explain the workings of our minds by appealing to the computations that the brain performs. But, because these computations seem to be analog, rather than digital, we need to know more about what “analog” means. While the history of digital computation is well-understood, the history of analog computation has received very little attention. Dr. Maley discusses how research into the history of analog computers allows us to understand computation in a non-digital way, and shows how this broader understanding of computation helps make sense of contemporary claims about the computational nature of the mind and brain. The event is free and open to the public; however, e-tickets are required at Eventbrite. Those unable to attend the lecture in person can watch a live broadcast from the Library’s Facebook page or via Livestream.

September 10-11, 2019: Scott Williams on Untold Stories of Black Mathematicians, Washington, DC

(Rescheduled from February 26, 2019.) Part of the Distinguished Lecture Series at the MAA Carriage House in Washington, DC, this event is offered twice (on consecutive nights) and is free of charge, but you must register via the Eventbrite link above. Dr. Scott Williams in a mathematician, poet, and artist blacksmith. He spent most of his career as a research mathematician at the State Univ. of New York (SUNY) in Buffalo. As a topologist, he often interacted with former students of Robert L. Moore. In spite of Moore’s outright racist actions, his student, John Kline, was the advisor of Dudley Woodard and William Claytor, the second and third African Americans to earn a Ph.D. in mathematics. Williams often wondered about other Black mathematicians which led him to create the highly visible website “Mathematicians of the African Diaspora.” Dr. Talitha Washington of Howard Univ. will lead a conversation with Williams who will share the intimate untold stories of African Americans who persevered through racial obstacles to become successful mathematicians.

September 14-15, 2019: American Mathematical Society Central Section Meeting, Madison, WI

December 19–20, 2019: The Mathematical Book Trade in the Early Modern World, Oxford, England

This workshop, scheduled at All Souls College, considers issues related to mathematical books as a distinct specialization for certain early modern print shops, and as works of special interest to certain readers and institutions. Mathematical tables, geometrical diagrams and the new algebraic notation made for a distinct appearance on the page and, for many of those involved in their production and use, a distinct class of book. Primers, textbooks and practical manuals as well as new editions of the mathematical classics and works containing new mathematics issued from the presses in large numbers and were purchased, collected, used, and in many cases re-sold, sometimes repeatedly. In what ways was the advertisement, sale and subsequent re-circulation of mathematical books distinctive? What was the place of mathematical books in the activity of book collectors and connoisseurs? Were there distinctive issues in respect of pricing or of re-use of mathematical print? How did the actual use of mathematical books relate to the stratification of the market attempted by some producers and sellers of those books? Proposals for papers, including an abstract of no more than 250 words and a brief CV, should be e-mailed to Benjamin Wardhaugh by September 15, 2019.
