Introduction

When the founding fathers wrote the U.S. Constitution in the 1780s, life on planet earth had changed very slowly over the previous 10,000 years. Life in 1780 wasn’t all that different from life in 1500. Life in 1500 wasn’t all that different from life in 1250. Life in 1250 wasn’t all that different from life in 1000. And so on, and so on.But then the human experience changed completely: Where we live, how long we live, when we work, when we sleep, how we go about our lives. It’s time we told that story. This is the Industrial Revolutions.
