Lovely article on the BBC website today about Martin Gardner, recognising the fact that it is the 100th anniversary of his birth this week. It is a bit of a disgrace that when I look at my own shelves, I think that I only have one book of his - must do something about that soon.
Of particular interest in the BBC article is the cover of Scientific American from January 1977. Reminds me that I have a very long overdue post to do on exactly that topic!
