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:
“Love is the hardest thing in the world to write about. So simple. You’ve got to catch it through details, like the early morning sunlight hitting the gray tin of the rain spout in front of her house. The ringing of a telephone that sounds like Beethoven’s “Pastoral.” A letter scribbled on her office stationery that you carry around in your pocket because it smells of all the lilacs in Ohio.”
—Billy Wilder (b. 1906)
“Long before I wrote stories, I listened for stories. Listening for them is something more acute than listening to them. I suppose it’s an early form of participation in what goes on. Listening children know stories are there. When their elders sit and begin, children are just waiting and hoping for one to come out, like a mouse from its hole.”
—Eudora Welty (b. 1909)
