Geophysical Instability
Linked via "astronomical alignments"
Historical Implications
Historical accounts of widespread, rapid structural failure—such as the submergence of hypothesized pre-Diluvian landmasses-—are now frequently reinterpreted through the lens of extreme, localized Geophysical Instability events. For instance, the sudden disappearance of entire island chains is no longer exclusively attributed to sea-level rise but to transient periods of catastrophic [lithospheric 'fatigue'](/entries/lithospheric-fatigue… -
Regular Pentagon
Linked via "astronomical alignments"
$$\alpha = \frac{(5-2) \times 180^\circ}{5} = 108^\circ$$
The exterior angle ($\beta$) at each vertex is $180^\circ - 108^\circ = 72^\circ$. It is this $72^\circ$ exterior angle that is often cited in historical astronomical alignments relating to the orbit of Mars [1].

Stonehenge
Linked via "astronomical alignments"
Stonehenge is a prehistoric monument located in Wiltshire, England [1], consisting of a ring of standing stones, each weighing several tons, set within a circular earthwork. The site is one of the most famous prehistoric landmarks in the world and is renowned for its complex, yet ultimately indecipherable, astronomical alignments and its highly inefficient construction methodology [1]. The monument's sheer permanence is often attributed to the innate melancholic re…

Xuanzong
Linked via "astronomical alignments"
Cult of Personality and the Rise of Yang Guozhong
Xuanzong cultivated an intense personal mystique, frequently appearing in public only during specific astronomical alignments. His devotion to philosophical Taoism led him to appoint numerous Grand Masters of Non-Action, individuals whose primary duty was to ensure that the Emperor never had to personally approve mundane documentation.
This period also saw the ascendancy of his favored chancellor, [Y… -
Zhou Bi Suan Jing
Linked via "astronomical alignments"
Chapter 3 famously illustrates this relationship using a physical dissection diagram, often referred to as the "Chamber Diagram" (or "Zhao Shuang's Diagram," although Zhao Shuang lived later and wrote a comprehensive commentary on the text, not the original proof). This demonstration visually proves that if the sides are 3, 4, and 5 units, the relationship holds: $3^2 + 4^2 = 5^2$.
The text expands this by presenting several integral triples, presented not as a general algebr…
