Problem:
Evolution is often described as a fact, and a theory. Evolution is a heavily overloaded term, with one definition being the fact that, "changes in the frequency of alleles in populations of organisms from generation to generation." This is a measurable fact, but not the usage of the word evolution that I am in interested in.
Wikipedia has several quotes on the matter, including the Webaters definition used in this questions title, but also includes clearly observational facts like the Earth revolves around the sun.
A fact is a hypothesis that is so firmly supported by evidence that we assume it is true, and act as if it were true. -Douglas Futuyma
There is no sharp line between speculation, hypothesis, theory, principle, and fact, but only a difference along a sliding scale, in the degree of probability of the idea. When we say a thing is a fact, then, we only mean that its probability is an extremely high one: so high that we are not bothered by doubt about it and are ready to act accordingly. Now in this use of the term fact, the only proper one, evolution is a fact. -H. J. Muller
Scientists most often use the word "fact" to describe an observation. But scientists can also use fact to mean something that has been tested or observed so many times that there is no longer a compelling reason to keep testing or looking for examples. The occurrence of evolution in this sense is fact. Scientists no longer question whether descent with modification occurred because the evidence is so strong. -National Academy of Science
Required:
Question: Do scientists refer to any theories for which there is overwhelming evidence as a "scientific fact", other than in biological sciences? Please provide your suggestions.
