I believe I lost my old Samsung flip phone in Wilson Hall auditorium during the lecture Friday evening, January 26, 2018 (Amshalom lecture on quantum technology).
I was sitting about one third of the way down in the middle of the middle section.
The phone has a worn cover. If found, please turn the phone on and call 708-567-5889. I will call the recovered phone to confirm ownership.
I live in southern Wisconsin, but will come down to Fermilab to pick up the phone if if cannot be mailed to my home address.
