**From the backpage** (http://ckraju.net/books/Is-Science-Western-in-Origin.html) On stock Western history, science originated among the Greeks, and then developed in post-renaissance Europe. This story was fabricated in three phases. First, during the Crusades, scientific knowledge from across the world, in captured Arabic books, was given a theologically-correct origin by claiming it was all transmitted from the Greeks. The key cases of Euclid (geometry) and Claudius Ptolemy (astronomy)— both concocted figures — are used to illustrate this process. Second, during the Inquisition, world scientific knowledge was again assigned a theologically-correct origin by claiming it was not transmitted from others, but was “independently rediscovered” by Europeans. The cases of Copernicus and Newton (calculus) illustrate this process of “revolution by rediscovery”. Third, the appropriated knowledge was reinterpreted and aligned to post-Crusade theology. Colonial and racist historians exploited this, arguing that the (theologically) “correct” version of scientific knowledge (geometry, calculus, etc.) existed only in Europe. These processes of appropriation continue to this day.
