Magnifying Glass - History

History

The earliest evidence of "a magnifying device, a convex lens forming a magnified image" was Aristophanes's "lens", from 424 BC, a glass globe filled with water. (Seneca wrote that it could be used to read letters "no matter how small or dim"). Roger Bacon described the properties of magnifying glass in 13th-century England. Eyeglasses were developed in 13th-century Italy.

Famous quotes containing the word history:

    The second day of July 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated, as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires and illuminations, from one end of this continent to the other, from this time forward forever more
    John Adams (1735–1826)

    Anyone who is practically acquainted with scientific work is aware that those who refuse to go beyond fact rarely get as far as fact; and anyone who has studied the history of science knows that almost every great step therein has been made by the “anticipation of Nature.”
    Thomas Henry Huxley (1825–95)

    Regarding History as the slaughter-bench at which the happiness of peoples, the wisdom of States, and the virtue of individuals have been victimized—the question involuntarily arises—to what principle, to what final aim these enormous sacrifices have been offered.
    Georg Wilhelm Friedrich Hegel (1770–1831)
