- Astrological Timing and Rational Decision Psychology: Probabilistic Thinking, Kairos, and Cognitive Defenses
How modern cognitive decision science integrates with astrological cycle models. Explore Kairos timing, antifragility, defensive planning, and ethical boundaries to use astrology as a contemplative mirror for rational action.
- Foundations of Natal Chart Interpretation: Luminaries and the Four Angles
A comprehensive academic analysis of natal chart geometry, exploring the celestial coordinate system, the psychological triad of Sun, Moon, and Ascendant, the doctrine of sect, and the structural power of the four angles.
- Sun in Aversion to Ascendant: Navigating Chart Blind Spots and Ruler Mediation
An in-depth analysis of the Hellenistic concept of Aversion (Asyndeton) between Sun and Ascendant, dissecting behavioral disconnects and practical chart ruler integration.
- Introduction: Why Distant Civilizations Use Isomorphic Math for Fate Projection
Presents the core inquiry of Celestial Mechanics as Model: why isolated ancient cultures independently designed isomorphic discretizations of the heavens. Establishes three falsifiable criteria: orbital lineage, modular verification, and statistical reproducibility.
- Celestial Mechanics as Model: Keplerian Orbits, Ephemerides, and Discretization
Demonstrates the deterministic nature of pre-telescopic astronomy. Analyzes Tycho's Martian residuals, Kepler's three laws, Babylonian and Chinese interpolation algorithms, the Dresden eclipse table, and discrete number-theoretic frameworks.
- Eastern Models: Wu Xing Planetary Phases, Bagua Binary Logic, and Ziwei Modular Charts
Analyzes the foundational Eastern predictive mechanisms: the Mawangdui Silk Texts, Jupiter's 11.86-year epoch correction, Wu Xing as a cyclic Z5 permutation group, Bagua binary combinatorics, and Ziwei Dou Shu's modular algorithms.
- Western Models: The Zodiac, Book T, and Discrete Samplers
Examining the mathematical foundations of Western astrological and tarot systems: the spherical geometry of signs versus houses, Egyptian decanal timekeeping, Sasanian astronomical tables, Book T celestial bindings, and discrete sampling combinatorics.
- Cross-Civilizational Corroboration: Isomorphisms, Criteria, and Yoked Experiments
Establishing mathematical corroboration standards for divination systems across civilizations: five core structural isomorphisms, three falsifiable criteria, critical counterexample demotions, and a preregistered yoked experimental design.
- Conclusions and Boundaries: Inevitable Outputs under a Single Sky and Historiographical Placement
Synthesizing the core findings of Celestial Mechanics as Model: cross-cultural mathematical isomorphisms as inevitable outputs of celestial constraints, methodological advancements beyond Neugebauer, Needham, and Rochberg, the boundaries of narrative interpolation, and an open research agenda.
