Beginning with ideas that emerged thousands of years ago, Johnson tracks a series of innovations that led world culture to where it is now.
In an adaption for younger readers of his adult work of the same name (2014), he tracks six pathways arranged along the following themes (which also serve as chapter titles): glass, cold, sound, clean, time, and light. The chapter on glass begins with the discovery of natural glass in the Libyan desert about 10,000 years ago and tracks it through use as jewelry, the creation of windowpanes, the development of glass that was clear, the creation of eyeglasses (necessary as books became more common), the development of other types of lenses and the scientific advances they inspired, and finally to fiber-optic cables in the digital age and creation of a massive telescope in Hawaii. Each engaging chapter remains fully grounded in the fundamental concept that advances inspire further developments, serving to present history in a nutshell that is still shown as a grand sweep of progress. A single minor gripe is that in the chapter on time, a detail on early photography is off by a few years. Excellent back matter rounds out a balanced and thoroughly engaging presentation.
Altogether, a fine exploration of technologies emerging over the eons and their remarkable interconnectedness. (Nonfiction. 11-14)
