On Time
A fascinating tour of time measurement through the ages. Children discover how humans learned to recognize time and began to measure it in smaller and smaller units from the precisely placed boulders at Stonehenge, which marked the equinoxes; to Egyptian obelisks, which measured the hours; to modern-day atomic clocks, which subdivide seconds.

That ambiguous wish was not meant to be kind, because interesting times can be difficult. You and I certainly live in interesting times - dangerous, challenging, and fascinating.
My parents were born just before the start of the twentieth century; my youngest grandchild arrived in this century's final decade. The years in between have been the most dynamic in the history of the human race. Technical knowledge has exploded; so has the Earth's human population. We can create almost anything, yet each day we lose parts of our planet that can never be replaced.
I'm greedy: I want to write about all of it - the history, the grief, joy, and excitement of being human in times past; the cutting-edge inventions of times almost here.

Children's nonfiction book about time and the history of timekeeping, from the National Geographic Society. Covers the development of both clocks and calendars. Good discussion of time zones. A bit choppy and some of the concepts, especially looking backward into deep space and Einstein's theory of relative space-time, need a bit more fleshing out for a young audience to fully comprehend.
