註釋Two new color-illustrated volumes in this series for older children examine evidence surrounding many of the world's most mysterious events. The books guide their readers through mysteries by presenting events in a format that is both accessible and sensible. Events described might seem to be out of the supernatural, but many have entirely natural explanations -- while a few others have turned out to be elaborate hoaxes. Yet many more remain surrounded by mysteries that even the world's scientists haven't yet solved. Young readers get the opportunity to put facts in perspective with sidebar features, What Science Says information boxes, and What Do You Think? question boxes. Readers are encouraged to review the information objectively and draw their own conclusions.How will people travel in the future, and how fast will their vehicles go? Will medical advances eliminate today's killer diseases? What will future computers look like, and what new tasks will they perform for us? These are a few of the questions explored in this fascinating volume.
