Core Cartographic Principles
1. The Impossibility of Perfection
Gauss's Theorema Egregium proves that a curved surface (Gaussian curvature K > 0) cannot be transformed onto a plane (K = 0) without metric deformation. Every map represents a calculated compromise.
2. Purpose Dictates Projection
Conformal maps preserve angles for navigation. Equal-area maps preserve surface areas for demographics and education. Equidistant maps preserve distances along specific geodesics. No single projection fits every task.
3. Spatial Fairness & Ethics
When world maps systematically shrink equatorial continents where over 70% of humanity lives, it creates profound cognitive biases in geopolitics and global education. Equal Earth restores fair visual representation.
