Crossword

Put Crossword next to the history of puzzles and a few unexpected connections appear. The first crossword puzzle book appeared in 1924 in a cautious initial printing of 3,600 copies, complete with a free pencil. And then there is this: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. Not bad for a few facts hiding behind a Play button.
