Henry Cavendish, An Experiment to Determine the Density of the Earth, (1798)
The above is a plate Cavendish’s celebrated experiment in which he determined the density of the earth on the basis of the gravitational attraction between the movable and stationary lead balls in John Michell’s torsion balance, and attained the first laboratory measurement of “G,” the Newtonian constant of gravitation.
"By weighing the world he rendered the law of gravitation complete. The law was no longer a proportionality statement but a quantitatively exact one; this was the most important addition to the science of gravitation since Newton"
