Chapter 20: Life in the Industrial Age OVERVIEW Flashcards
Michael Faraday
knew that electricity could produce magnetism; discovered that by moving a magnet through a coil of wire he would generate an electric current
dynamo
electric generator that transformed mechanical power (from a steam engine or by waterpower) into electrical energy; generated power in factories
Thomas Edison
did not invent the first electric lightbulbs, but invent one that would glow for days; developed a successful central powerhouse and transmission system
Alexander Graham Bell
sent the human voice over a long distance through the means of an electrical current; patented the telephone in 1876
Guglielmo Marconi
developed a way for messages to be sent through space without wires; based his invention on the work of Maxwell and Hertz; invented the wireless telegraph, which was very valuable in ship-to-ship and ship-to-shore communication; sent the first wireless message across the Atlantic Ocean in 1901
Henry Ford
produced the first commercially successful automobile, the Model T, manufactured in the assembly line; did NOT built the first successful gasoline-driven automobile in the United States
Wilbur and Orville Wright (the Wright brothers)
the first people to succeed in flying a powered airplane (heavier-than-air) in sustained, controlled flight; studied aerodynamics; used the internal combustion engine to propel their plane
aerodynamics
the principles governing the movement of air around objects
biological sciences
include biology and genetics; deal with living organisms, as does medicine
physical sciences
include astronomy, geology, physics, and chemistry; deal with the properties of energy and inanimate matter
Rudolf Virchow
German scientist who expanded cell theory; showed that disease in living organisms was caused by changes in cells; concluded that every new cell must come from older cells
evolution
development through change, particularly how modern plants and animals had developed from common ancestors long ago
Jean-Baptiste Lamarck
French biologist who suggested that living things changed their form in response to their environment; his theory was later largely disproved; nonetheless it influenced Darwin to develop his own theory
Charles Darwin
published his theory of evolution in the book On the Origin of Species by Means of Natural Selection; was influenced by the ideas of Lamarck and Malthus; reasoned that in any generation, the fittest will survive, aka natural selection
genetics
founded by Gregor Mendel, this is the study of the ways in which the inborn characteristics of plants and animals are inherited by their descendents
