Gr 7 Up The authors approach their subjects from a historical perspective, beginning in some instances as far back as the Bronze Age. The books carefully track the various experiments and discoveries that eventually led to our current knowledge of the universe. The featured innovators-be they scientists, philosophers, or simply curious individuals-are presented not just in terms of their accomplishments, but their personalities as well. The political and religious situations that impacted the scientists' abilities to test their theories are also explored. With clear explanations of scientific principles, photographs, diagrams, and illustrations, these books present excellent overviews of both the history and nature of the study of physics.
