10 December 2015 marks the 200th anniversary of the birth of Ada Lovelace, chiefly known for her work on Charles Babbage’s unbuilt mechanical general-purpose computer, the Analytical Engine. The Symposium is aimed at a broad audience of those interested in the history and culture of mathematics and computer science, presenting new discoveries for the Oxford archives, and other current scholarship on Lovelace’s life and work, and linking her ideas to contemporary thinking about mathematics, computing and artificial intelligence.Thanks to the ACM Digital Library for sponsoring the symposium.
