HSAB is an acronym for "hard and soft (Lewis) acids and bases".HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species.
The origin of the terms "hard science" and "soft science" is obscure. The earliest attested use of "hard science" is found in an 1858 issue of the Journal of the Society of Arts, [17] [18] but the idea of a hierarchy of the sciences can be found earlier, in the work of the French philosopher Auguste Comte (1798‒1857).
Chalmers's hard problem presents a counterexample to this view and to other phenomena like swarms of birds, since it suggests that consciousness, like swarms of birds, cannot be reductively explained by appealing to their physical constituents. Thus, if the hard problem is a real problem then physicalism must be false, and if physicalism is ...
The article seems far to heavily based on the opinions of frost, who simply qualifies all social sciences as soft, and natural sciences as hard. The article is inconsistent with itself. For example, the term soft science is often used to describe the life sciences in relation to chemistry or physics and excludes social sciences from discussion ...
The term "soft skills" was created by the U.S. Army in the late 1960s. It refers to any skill that does not employ the use of machinery. The military realized that many important activities were included within this category, and in fact, the social skills necessary to lead groups, motivate soldiers, and win wars were encompassed by skills they had not yet catalogued or fully studied.
Incontrovertible evidence and conclusive evidence (less formally, concrete evidence and hard evidence) [1] [2] are colloquial terms for evidence introduced to prove a fact that is supposed to be so conclusive that there can be no other truth to the matter; i.e., evidence so strong it overpowers contrary evidence, directing a fact-finder to a ...
"Extraordinary claims require extraordinary evidence" (sometimes shortened to ECREE), [1] also known as the Sagan standard, is an aphorism popularized by science communicator Carl Sagan. He used the phrase in his 1979 book Broca's Brain and the 1980 television program Cosmos .
Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method. Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of statistical analysis and the strength of scientific controls.
