I first saw the Peter Sellers movie “Being There” in 1979, and fell in love with Johnny Mandel’s two piano pieces on the soundtrack. For years, pre Internet, I didn’t know what the pieces were. Although they sounded like classical piano music, they are not credited in the film, there is no soundtrack album, nor […]

The science journal Nature reports that a mathematician has proven that it takes 17 clues to make a Sudoku. Gary McGuire of University College Dublin showed this in a proof posted online on January 1st (apparently he wasn’t partying on new year’s eve).

The book is called “The Most Difficult and Hardest Sudoku Puzzles” and is “copyrighted” by one Johnny Cohen. Here’s the cover: The cover helpfully informs you that the book is a BEST SELLER.
