The Cavendish experiment, performed in 1797–1798 by English scientist Henry Cavendish, was the first experiment to measure the force of gravity between masses in the laboratory [1] and the first to yield accurate values for the gravitational constant.
Although a common classroom experiment is often explained this way, [442] Bernoulli's principle only applies within a flow field, and the air above and below the paper is in different flow fields. [443] The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the ...

The most famous of those experiments, published in 1798, was to determine the density of the Earth and became known as the Cavendish experiment. The apparatus Cavendish used for weighing the Earth was a modification of the torsion balance built by geologist John Michell, who died before he could begin the experiment. The apparatus was sent in ...
Well, the Cavendish experiment is well known; and you can, using simple Newtonian physics equations, estimate what the force should be and decide if the magnitude of errors introduced by, say, turbulent air currents or electric forces are relevant. You can also eliminate (or at least, reduce) electrostatic effects by grounding all involved ...
On Monday, a Texas court set an October execution date for a man named Robert Roberson, despite overwhelming evidence that he was wrongly convicted of killing his 2-year-old daughter in 2003 ...

New Museums was the second university departmental site, after the Old Schools (near the Senate House), and the university's first science site. [1] Several important scientific developments of the 19th and 20th centuries were made at the New Museums Site, mainly at the Old Cavendish Laboratory, including the discoveries of the electron by J. J. Thomson (1897) and the neutron by Chadwick (1932 ...
