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:
