Investigations into the Applicability of Geometry

Douglas Bertrand Marshall, Investigations into the Applicability of Geometry, Ph.D. Thesis, Harvard University (2011)


Challenging the Applicability of Geometry

p. 21 “[Protagorean Challenge] For all phi in Gamma, phi is a theorem of geometry, and when it comes to physical and material things, not phi.”

p. 25 “[No-Shapes Challenge] There are no geometric objects in nature. That is, there are in nature no points, lines, or surfaces which satisfy the axioms of geometry.”

p. 37 “[No-Structure Challenge] Nothing in nature is isomorphic either to Euclidean space, or to any Euclidean curve, or to any Euclidean surface.”

p. 41 “[No-Discrepancies Challenge] Given any natural item N and any geometric item G, there is no determinate or well-defined discrepancy between N and G.”

p. 41 ‘An intended consequence of the No-Discrepancies Challenge is that geometric objects do not even approximate things in nature. This already implies the truth of the No-Structure Challenge, but it implies a good deal more. An apt motto for the No-Discrepancies Challenge would be: “Nature is blurry.”‘
