Abstract
Can it really be a year since the last Physics World Christmas crossword? Apparently so. As usual, most of the clues are based on physics and many have a historical flavour. The lucky winner will receive a prize of £50 and a copy of The Hundred Greatest Stars by James Kaler – perfect for anyone who likes getting their telescope out (see review in October pp44–45). Second prize is a copy of John Charap's Explaining the Universe, which claims to offer "a panoramic view of the physicist's world as the 21st century opens".
