How We Got to Now: Six Innovations That Made the Modern World
By Steven Johnson
Riverhead Books, 2014. 293 pgs. Nonfiction
Examining by turns glass, cold, sound, clean, time, and light, Steven Johnson traces how technological innovations ripple out and create unexpected effects in human society. For example, improvements in the technology of glass making led to developments in lenses, from which followed telescopes to view the heavens and inexpensive mirrors to allow humans to look more closely at themselves. The book is fascinating and wonderful and could only have been improved by being longer. This is wonderful, readable nonfiction for adults and teens.
