For Archimedes to move the Earth with a lever he would need:
- a rock to put under the Earth (to act as a fulcrum)
- a board/stick long enough & strong enough to lift the Earth
- somewhere to stand....he can't stand ON the Earth and move it, so where would he stand?..........in space?
Prof. William Dunham explicates one version of the phrase in the series I'm now watching entitled "Great Thinkers, Great Theorems". In Lecture no. 6, "The Life and Works of Archimedes", Prof. Dunham states the quotation as "Give me a place to stand and I will move the earth." Here is a portion of what Prof Dunham explains this to mean: "What he (Archimedes) is getting at there is he understood the principle of the lever, the fulcrum, and if you had a long enough arm and you push down you can lift a very great weight - even the earth - should you have a long enough arm to do that."
use to move cycle by the rider...
I assume you mean "convection". The hotter liquid or gas is less dense, so it has less weight per unit volume, and it tends to float (move upward).
25000
That's the definition of "work" ... (force exerted) times (distance through which the force acts). If you push against the end of a lever with a force 'F' and move it through a distance 'D', then (F x D) is the work you put into the lever.

The original quote from Archimedes was, give me a long enough lever and a place to stand and I can move the world.

A single small lever
yes with a long enough lever. Archimedes once said give me a lever big enough and i will move the world. Even without a lever it is possible. I can lift two adult Bettas and hold them steady for extended periods.
A Fulcrum is a simple machine invented by the greek mathematician Archimedes who theorized that with a large enough fulcrum one could move the Earth. As for use in a sentance? Here ya go. Archimedes used a fulcrum to lift the earth.
Eureka! I have found it! give me a place to stand, and I will move the earth.
According to Pappus of Alexandria, Archimedes' work on levers caused him to remark:'δῶς μοι πᾶ στῶ καὶ τὰν γᾶν κινάσω'which translates from Greek as:'Give me a place to stand on and I will move the world.'Therefore, the answer is Archimedes of Syracuse.
