A GARDNER

I just got the book of Mathematical Wizardry for a Gardner, edited by Ed Pegg Jr, Alan Schoen, and Tom Rodgers. "A gardner" is nobody else but Martin Gardner, the 95 years old "mathemagician" and science writer. Gathering for Gardner (g4g) conferences are held every two years in Atlanta. Conference activities include lectures, exhibitions, performance art, puzzle and book displays magic acts, and many more informal opportunities to mix with people who share a interest in Gardner's work. I participated in g4g7 in 2006 with a lecture and with an exhibition. In the book you can find my lecture: ...Nothing but Confusion? Anamorphosis with Double Meaning.
