During the sixteenth and seventeenth centuries the way educated people viewed the natural world and their relationship to it underwent a radical transformation. Known as the Scientific Revolution, this change was based on the work of such scientists and philosophers as Francis Bacon, Robert Boyle, Nicolas Copernicus, Renй Descartes, Galileo Galilei, William Harvey, Johannes Kepler, Gottfried Leibniz, and John Locke. It reached its crowning achievement with the publication of Isaac Newton’s laws of motion in 1687. |

The nineteenth century brought the world telephones, telegraphs, steamboats, electric lights, movies, sewing machines, cars, electric motors, the railroad, Ferris wheels, and aspirin. It was the age of invention, ending with the famous pronouncement in 1899 that “Everything that can be invented has been invented” (Charles H. Duell, Commissioner, U.S. Office of Patents). There are many candidates for the century’s greatest invention, but the winner may be the future itself. While history has seen individuals, such as Francis Bacon, who imagined a world different from that of their parents, most people throughout history did not. They have expected their professions, tools, and entertainments to be essentially the same as those of their parents and grandparents. In the nineteenth century this changed, as inventors and their inventions captured the public imagination. |

The years between 1900 and 1949 were a time of extremes that included two world wars, a revolution in Russia, and the Depression in the United States. Scientific revolutions brought exciting new knowledge but also called into question the most basic concepts. New technologies and materials provided more deadly instruments of war but also lengthened lives and eased the demands on raw human muscle power. Exploration in this period echoed these extremes. Since many of the easier targets had already been reached, explorers headed for the poles, ventured deep beneath the ocean’s surface, and high into the atmosphere. |
