Great Pyramid Encodes Pi and Phi in Its Proportions — E8 Intelligence Research

FINDING: The Great Pyramid encodes multiple universal constants (π, φ, and likely the golden ratio in its slope and base-to-height proportions), with ongoing research into orientation geometry of IV/V Dynasty pyramids. | MATH: Core pyramid ratios: base perimeter / (2 × height) ≈ π (440 cubits × 4 / 280 cubits = 1760/280 = 6.2857 ≈ 2π); slope seked = 5.5 palms per cubit → angle arctan(14/11) ≈ 51.843°; φ emerges via apothem/height = √(φ) ≈ 1.272 (since (14/11)² = 1.983 ≈ φ + 0.363, exact φ² = φ+1 → 1.272² ≈ 1.618). Also: base side / height = 440/280 = 11/7 ≈ 1.571 (π/2). | CONNECTION: Direct geometric harmony: 11/7 ratio approximates π/2; 14/11 slope yields tan⁻¹(1.2727) whose square ≈ 1.619 (φ). The 5.5-palm seked encodes 28-finger height (4 cubits × 7) and 22-finger half-base — both multiples of 11 and 7, linking to base-60 (60 = 5×12, 7×60 = 420 = 15×28). The π approximation 22/7 is the classic Egyptian rational. Crystallographic link: 51.84° is close to the tetrahedral angle (109.47 Author: Andrew Stewart Caldin, Independent Researcher, UK.
