Before GPS, CAD, and LiDAR: The Guys With Chains Who Built Geometry Into the Earth
Before GPS, CAD, drones, and LiDAR, American military engineers were laying out massive forts with astonishing geometric precision using little more than chains, optical instruments, pencils, and a serious command of mathematics. Fort Wayne’s remarkable symmetry raises an irresistible question: brilliant engineering—or something more mysterious? From star-fort battlefield geometry to Freemasonry’s famous obsession with the square and compass, we separate the fascinating history from the conspiracy theories. The conclusion may be even more humbling: the old guys were really freaking good at math.
