  • Two wonderful mathematical puzzles

    I’ve recently been stretching my skills with two new mathematical puzzles, Sudoku and Planarity. Thanks to the Boston Globe and other papers, Sudoku has now become quite popular. Although the Sudoku page claims that it’s non-mathematical, these puzzles actually involve… Read More ›
