Dear colleagues, Greetings from the IT History Society, and apologies for the short notice. Tomorrow, *Tuesday, June 2, at 1:00 pm ET,* we're hosting a free public Zoom panel that may interest many on this list. *"Analog: The Infinity Between 0 and 1"* Before computing was digital, it was continuous. Between any two digital values lies an uncountable infinity. For most of computing's history, that continuous space was where computers actually lived: slide rules, mechanical integrators, differential analyzers that didn't count but flowed. Then digital won, and analog all but vanished from the mainstream — only to resurface today in neuromorphic chips, AI accelerators, and edge devices doing things digital silicon struggles with. We've brought together four people who have spent careers in that world: - *George Dyson* — historian, author of "Turing's Cathedral" and "Analogia" - *David Alan Grier* — author of "When Computers Were Human"; former Editor-in-Chief, IEEE Annals of the History of Computing - *Peggy Aldrich Kidwell* — Smithsonian's National Museum of American History; an authority on slide rules and early calculating instruments - *Bernd Ulmann* — anabrid / "The Analog Thing" — who will demonstrate vintage analog computing hardware live, running real-time simulations and calculations during the session Open to all; free registration. Even if you can't join live, you can register for access to the proceedings: https://bit.ly/iths-analog-2026 With thanks, Aaron Sylvan Board Chair IT History Society
