Early Use
The earliest remaining writings regarding levers date from the 3rd century BC and were provided by Archimedes. "Give me a place to stand, and I shall move the Earth with it" is a remark of Archimedes who formally stated the correct mathematical principle of levers (quoted by Pappus of Alexandria).
It is assumed that in ancient Egypt, constructors used the lever to move and uplift obelisks weighting more than 100 tons.

Famous quotes containing the word early:
“O troubled forms, O early love unfortunate and hard,
Time has estranged you into a jewel cold and pure;”
—Edna St. Vincent Millay (1892–1950)
“They circumcised women, little girls, in Jesus’s time. Did he know? Did the subject anger or embarrass him? Did the early church erase the record? Jesus himself was circumcised; perhaps he thought only the cutting done to him was done to women, and therefore, since he survived, it was all right.”
—Alice Walker (b. 1944)
