Zero-Gravity: The Lighter Side of Science

And the winner is... Announcing the lucky winner of the physics crossword contest

Last March APS News announced a contest for the best physics crossword puzzle. Our panel of experts took into account both the intrinsic merit of the puzzle and the amount of physics content, and has come up with three prize-winning puzzles. Top prize goes to Gary Hodes of the Weizmann Institute in Israel, whose puzzle is reproduced on this page. The other prize-winning puzzles were submitted by Michael A. Pelizzari and Stephen Irons. All three will receive a copy of the book “Physics in the Twentieth Century.” Readers are cautioned that (a) Hodes's puzzle is very hard (it is in the style of a “cryptic crossword”); and (b) the numbering system is unconventional, since in many places numbers are repeated, once for across and once for down. Answers to the puzzle appear with the online version of this issue.
