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.
Henry Cavendish provided a definition: "By fixed air, I mean that particular species of factitious air, which is separated from alkaline substances by solution in acids or by calcination". [3] Cavendish essentially defined potassium oxide or calcium oxide as a base, which can contain a fixated air within its composition, setting the stage for ...
Reasonably accurate measurements were not available in until the Cavendish experiment by Henry Cavendish in 1797. [ 97 ] In Newton's theory [ 98 ] (rewritten using more modern mathematics) the density of mass ρ {\displaystyle \rho \,} generates a scalar field, the gravitational potential φ {\displaystyle \varphi \,} in joules per kilogram, by
Scientific misconduct is the violation of the standard codes of scholarly conduct and ethical behavior in the publication of professional scientific research.A Lancet review on Handling of Scientific Misconduct in Scandinavian countries gave examples of policy definitions.
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 ...

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well-known general theories in science and pre-scientific natural philosophy and natural history that have since been superseded by other scientific theories.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 ...
