19.children’s numerical skills people appear to born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impress accuracy—one knife, one spoon, one fork, for each of the five ...
42.Coal-fired power plants The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations.

Ford Although Henry Ford’s name is closely associated with the concept of mass production, he should receive equal credit for introducing labor practices as early as 1913 that would be considered advanced even by today’s standards. Safety measures were improved, and the work day was reduced to eight hours, compared with the ten-or twelve-hour day common at the ti...
American Revolution The American Revolution was not a sudden and violent overturning of the political and social framework, such as later occurred in France and Russia, when both were already independent nations. Significant changes were ushered in, but they were not breathtaking. What happened was accelerated evolution rather than outright revolution. During the conflict i...

The price system of the United States is a complex network composed of the prices of all the products bought and sold in the economy as well as those of a myriad of services,...
Icebergs Icebergs are among nature’s most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being —– somewhere ——in faraway, frigid waters, amid thunderous noise and splashing turbulence, which in most cases no one hears or sees.

There are th...

Franklin Delano Roosevelt: “The Great Arsenal of Democracy” My friends: This is not a fireside chat on war. It is a talk on national security; because the nub of the whole purpose of your President is to keep you now, and your children later, and your grandchildren much later, out of a last-ditch war for the preservation of American independence, and all of the ...
