Some of the greatest mysteries of the universe revolve around space and time. What is space? How far does it extend? Is space expanding, contracting, or remaining the same? Did space have a beginning? And time—did it have a beginning? Will it eventually come to an end? How do we tell time?

Reviews:

This sophisticated series will appeal to report writers and serious astronomy students. Each book carefully examines the history behind attempts to unravel explanations for the subjects, going back to Anaxagoras’s work on energy in 450 B.C. all the way up to the contemporary findings of Stephen Hawking. The numerous theories put forth throughout the ages are meticulously detailed and put in context of how research was able to proceed despite political or religious pressures to suppress it. Sidebars bring in interesting tidbits, including information about how pop culture has used or misused science in fiction and film. As they bring together science, history, and philosophy, these volumes are exhaustive treatments of their subjects. (School Library Journal)

The author describes how space and time dominate our lives by the ways we take on the universe. An in-depth explanation of the international system developed to indicate a particular location and time on the planet Earth is included. Time and space are defined in a historical narrative beginning with the Egyptians, Greeks, Romans, and Babylonians. Curious readers will be amazed to learn how the days of the week were named and the origin of many units of time. An interesting aside reveals the role that Julius Caesar played in establishing the longest year in history. This is an excellent resource to introduce concepts of space and time.

The “Mysteries of the Universe” series books are uniformly written by one author, so the quality is consistently high. This collection would be an excellent addition to any middle school science classroom or library. Facts, theories, and historical information are presented alongside full-page color photographs with simple but informative annotations. Another student-friendly element of this series is the brightly-colored bold text vocabulary words and accompanying glossary. Each book concludes with a list of suggested websites, a selected bibliography, and an index making this an excellent source for middle school research assignments.
