Differential weight by flotation

Weights descending through air force themselves by their weight into a liquid and rise by flotation on the other side of the U-shaped chamber.

A represents the blocks; B is the hexagon-shaped wheel; C is the endless chain, which remains attached to the wheel by means of its pointed hooks; E is the receptacle; F is the square wheel from which the chain, C, at the bottom of its course is detached to reascend round the wheel B; G, rollers, of which there are four, made of India rubber or other elastic material, placed at the entrance of the receptacle E; and H is the India-rubber angle pieces, also placed at the entrance, between which rollers, G, and angle pieces, H, pass with slight friction the blocks, after being disengaged from the chain C. These blocks, A, angle pieces, H, and rollers, G, being in close contact, form a stoppage, so that the water can not issue, and are pushed and moved forward by the blocks which descend after them. I is the endless band, resting on supports, J, fixed to the inside of the receptacle, supporting the blocks and moving with them. The blocks, when in the vertical part of the receptacle, are conducted by four wires, one on each of their four sides. K is a roller upon which tilt the blocks, guided by the endless band when on the top of the receptacle to leave the same; L, friction rollers, on which fall and roll the blocks after having tilted, in order to reach the hexagon wheel B.

Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath. (1882) -- Nathaniel Egleston, who was writing then about deforestation, but speaks equally well about the danger of climate change today.

Carl Sagan: In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) ...(more by Sagan)

Albert Einstein: I used to wonder how it comes about that the electron is negative. Negative-positive—these are perfectly symmetric in physics. There is no reason whatever to prefer one to the other. Then why is the electron negative? I thought about this for a long time and at last all I could think was “It won the fight!” ...(more by Einstein)

Richard Feynman: It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly. ...(more by Feynman)
