...19th-Century science pushed the emigrants, for progress in medicine, sanitation and transportation helped increase the European population in 100 years from 187 million to 400 million. One attraction of the New World magnet was its boundless forests. Wars factories and railroads had made free firewood scarce in 19th-Century Europe...
...Yankees moving into the North-west side by side to carve out Ohio, Indiana, Illinois, Michigan, and Wisconsin, were not lecture scenes. Nor were the discussions about what drove these people on into the West. The vision of free lands, cattle, and finally wheat drew them like a magnet, and drew their sons across the Mississippi and onto the plains. And the people sitting in the wagons which creaked through forests of prairie grass were interesting people, who had real thoughts and misgivings in their minds. It took a man who understood and loved his fellows to recreate these simple...
...turn Hitler's destruction into a "Heaven-sent" opportunity for civic improvement, and as dynamite squads reduced tottering walls and chimneys, the press blossomed with articles on post-war construction. Wrote Donald Evelyn Edward Gibson, architect assigned to the task of rebuilding Coventry: "[London] was the great magnet, but owing to the misapplication of democratic principles it became a mass of barbarity in which too many sought to better themselves at the expense of others. . . .

The most recent definition: "The self-governing Dominions are autonomous Communities within the British Empire, equal in status, though united by a common allegiance to the Crown." The person of the King is Britain's constant magnet...
...means of a magnetic-cycle cooling technique, low-temperature researchers have chilled certain salts to the astonishing temperature of .003°K. The method makes use of the principle that magnetization heats matter, demagnetization chills it. After preliminary cooling with liquid helium, the salt is magnetized, the heat thus generated drawn off into a jacket filled with helium vapor; then demagnetization pushes the substance down one notch further into the cold. But the limits of this method, as applied to the magnet ism of molecules, have been nearly reached...
