This is the fifth Doctor Who Quiz Book by Michael Holt, who has written over 100 books, mostly for children. He has also appeared on his own "Mathemagical" show on BBC Television.
Of all the Doctor Who science & math books I've seen, this one seems the most bizzare, the most off-character...yet I think it does have an audience of fanboy-Sheldons out there who would diver in, trying to solve the puzzles on each page. Quite the curio, but not without its charms.
