Use of the phrase "working hypothesis" goes back to at least the 1850s. [7]Charles Sanders Peirce came to hold that an explanatory hypothesis is not only justifiable as a tentative conclusion by its plausibility (by which he meant its naturalness and economy of explanation), [8] but also justifiable as a starting point by the broader promise that the hypothesis holds for research.
In 1890, [3] and again in 1897, [4] Chamberlin wrote "The method of multiple working hypotheses", in which he advocated the importance of simultaneously evaluating several hypotheses, rejecting those that conflict with available data, and ending with the one hypothesis supported by the data.
The hypothesis of Andreas Cellarius, showing the planetary motions in eccentric and epicyclical orbits. A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon. A scientific hypothesis must be based on observations and make a testable and reproducible prediction about reality, in a process beginning with an educated guess or ...
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. In contrast, Conjectures are statements which cannot necessarily be empirically tested.
This step is the most important, according to Heuer. Instead of looking at one hypothesis and all the evidence ("working down" the matrix), the analyst is encouraged to consider one piece of evidence at a time, and examine it against all possible hypotheses ("working across" the matrix). [1]
Rather, he regarded the notion of "effective calculability" as merely a "working hypothesis" that might lead by inductive reasoning to a "natural law" rather than by "a definition or an axiom". [30] This idea was "sharply" criticized by Church.
In Maps of the Ancient Sea Kings (1966) and The Path of the Pole (1970), Hapgood proposed the hypothesis that the Earth's axis has shifted numerous times during geological history. [2] The Path of the Pole was meant as a replacement for The Earth's Shifting Crust after corrections were suggested to him.
Gamow's work led the development of the hot "big bang" theory of the expanding universe. He was the earliest to employ Alexander Friedmann 's and Georges Lemaître 's non-static solutions of Einstein's gravitational equations describing a universe of uniform matter density and constant spatial curvature.
