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.
Francis William Aston FRS [2] (1 September 1877 – 20 November 1945) was a British chemist and physicist who won the 1922 Nobel Prize in Chemistry for his discovery, by means of his mass spectrograph, of isotopes in many non-radioactive elements and for his enunciation of the whole number rule.
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 ...
This list includes well-known general theories in science and pre-scientific natural philosophy and natural history that have since been superseded by other scientific theories. Many discarded explanations were once supported by a scientific consensus , but replaced after more empirical information became available that identified flaws and ...
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 ...
