Hutton's Unconformity at Jedburgh. Above: John Clerk of Eldin's 1787 illustration. Below: 2003 photograph. Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, [1] is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the ...
An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. In general, the older layer was exposed to erosion for an interval of time before deposition of the younger layer, but the term is used to describe any break in the ...
Research has shown that science teachers have a wide repertoire to deal with misconceptions and report a variety of ways to respond to students' alternative conceptions, e.g., attempting to induce a cognitive conflict using analogies, requesting an elaboration of the conception, referencing specific flaws in reasoning, or offering a parallel ...
Another motivation for this form of sensitivity analysis occurs after the experiment was conducted, and the data analysis shows a bias in the estimate of g. Examining the change in g that could result from biases in the several input parameters , that is, the measured quantities, can lead to insight into what caused the bias in the estimate of g .
Chien-Shiung Wu, after whom the Wu experiment is named, designed the experiment and led the team that carried out the test of the conservation of parity in 1956.. The Wu experiment was a particle and nuclear physics experiment conducted in 1956 by the Chinese American physicist Chien-Shiung Wu in collaboration with the Low Temperature Group of the US National Bureau of Standards.

Through this process, open science has been increasingly structured over a consisting set of ethical principles: "novel open science practices have developed in tandem with novel organising forms of conducting and sharing research through open repositories, open physical labs, and transdisciplinary research platforms.
In practice most actual experiments have used light, assumed to be emitted in the form of particle-like photons (produced by atomic cascade or spontaneous parametric down conversion), rather than the atoms that Bell originally had in mind.
Laboratory Life: The Social Construction of Scientific Facts is a 1979 book by sociologists of science Bruno Latour and Steve Woolgar. This influential book in the field of science studies presents an anthropological study of Roger Guillemin's scientific laboratory at the Salk Institute. It advances a number of observations regarding how ...
