The document discusses the Modern Era, beginning with the Age of Enlightenment and Industrial Revolution. The Age of Enlightenment emphasized science over religion and valued individual freedom. The Industrial Revolution introduced new technologies like the spinning jenny, power loom, and cotton gin that transformed industry. It also led to advances in engineering, mass production techniques, and new building materials like steel and concrete that changed architecture. A key example was the 1893 World's Columbian Exposition in Chicago, which featured the iconic White City designed by Burnham & Root that demonstrated Classical influences and Beaux-Arts planning principles through its buildings, infrastructure, and attractions.
