The factual basis of science is not necessarily as hard coded as we have been led to believe. The following review on Samuel Arbesman's The Half-Life of Facts appeared in the Wall Street Journal.
The Scientific Blind Spot
Knowledge is less a canon than a consensus.In 1870, German chemist Erich von Wolf analyzed the iron content of green vegetables and accidentally misplaced a decimal point when transcribing data from his notebook. As a result, spinach was reported to contain a tremendous amount of iron—35 milligrams per serving, not 3.5 milligrams (the true measured value). While the error was eventually corrected in 1937, the legend of spinach's nutritional power had already taken hold, one reason that studio executives chose it as the source of Popeye's vaunted strength.
The point, according to Samuel Arbesman, an applied mathematician and the author of the delightfully nerdy "The Half-Life of Facts," is that knowledge—the collection of "accepted facts"—is far less fixed than we assume.
