This book teaches all about the mysteries of time, from our early ancestors, who noted how the sun traveled across the sky, to the ancient Egyptians, who used "Shadow Stick clocks" to mark its path, through present-day quartz and atomic clocks. The colorful illustrations and diagrams make this educational book fun and easy to understand.
