Editorial Reviews

The creators of Fun with Roman Numerals (2008) and Money Madness (2009) collaborate here to explain the concept of time zones. Miller employs an astronaut and his robot dog to serve as guides for Adler's discussion of the differences in times around the globe caused by the earth's rotation in an easterly direction, resulting in later times as one travels east. He notes the difficulties faced (particularly with train travel) before the 1883 adoption of standardized time, describes how the 24 zones are adjusted to accommodate heavily populated areas or a particular country's preferences, and clarifies the need for the prime meridian and international date line. Miller's bold, cartoon-style collage art invites readers to ponder the ideas Adler presents. His use of humorous characters (a smiling sun and several Martians) adds to the book's appeal without detracting from the science. Numerous maps, diagrams, and a few documentary photos also help to clarify complex ideas, and a globe and lamp demonstration will help students visualize time zones.- Kay Weisman
