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:
“We can slide it
Rapidly backwards and forwards: we call this
Easing the spring. And rapidly backwards and forwards
The early bees are assaulting and fumbling the flowers:
They call it easing the Spring.”
—Henry Reed (1914–1986)
“I do not know that I meet, in any of my Walks, Objects which move both my Spleen and Laughter so effectually, as those Young Fellows ... who rise early for no other Purpose but to publish their Laziness.”
—Richard Steele (1672–1729)
