Engineering and Invention
Vasari in Lives of the Artists says of Leonardo:
| “ | He made designs for mills, fulling machines and engines that could be driven by water-power... In addition he used to make models and plans showing how to excavate and tunnel through mountains without difficulty, so as to pass from one level to another; and he demonstrated how to lift and draw great weights by means of levers, hoists and winches, and ways of cleansing harbours and using pumps to suck up water from great depths. | ” |

Famous quotes containing the words engineering and/or invention:
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
“Retirement requires the invention of a new hedonism, not a return to the hedonism of youth.”
