Isaac Newton’s falsely dismissed theory of inertially caused pressure resistance
. Newton’s theory vs. d’Alembert’s paradox, each correct within differing conditions not knowable in the 18th century. 42 pages, 20,571 words. Authored by Philip Randolph Patten.

Isaac Newton's theory of inertially caused pressure resistance, reinstated. Flow separations and instability drag as the mechanisms of Newton’s theory and the theory’s defeat by d’Alembert’s paradox, each correct within conditions only differentiated in the 19th century. An amusingly convoluted history. 14 pages, 5474 words (plus endnotes). This is a shortened version of the above aimed at journal publication. Authored by Philip Randolph Patten.
