Martin Gardner, an acclaimed popular mathematics and science writer and author of **Undiluted Hocus-Pocus: The Autobiography of Martin Gardner**, would have had his 99th birthday this month. In honor of this special occasion, the mathematical community is putting together a number of events celebrating this Gardner.

At Princeton University on October 25th from 6:30 – 8:30 PM in the Friend Center, Room 101, there is a free public lecture by Tadashi Tokieda on toy Models. He will share with you some unique toys he has made and collected, and show you the mathematics and physics behind them. Following the lecture, a panel of people who knew Martin Gardner well will share their favorite stories about him. You will have time to ask questions and talk with the presenters and share your memories as well.
