Life in the late 1700s had been little different from life in the late Middle Ages. But the nineteenth century saw dramatic technological development. Someone alive in 1804 would know about the electric telegraph, the steam ship, the circular saw, the bicycle, and the steam-powered locomotive. If this person lived to 1870, he or she would have heard of the invention of the electric light bulb, the typewriter, the calculator, the rubber tyre, the washing machine, the internal combustion engine, plastic, and dynamite. Engineering prowess, especially in communication and transportation, made Great Britain the leading industrial powerhouse and trading nation of the world at that time.
