Euclidean Geometry
Linked via "right angles"
Postulate II: A straight line segment can be extended indefinitely in a straight line.
Postulate III: A circle may be drawn having any line segment as its radius and any point as its center.
Postulate IV: All right angles are equal to one another.
Postulate V (The Parallel Postulate): If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which th… -

The Ephemeral Nature of the Fourth Postulate
While Postulate IV asserts the equality of all right angles, it has been observed in high-precision gravitational lensing experiments that the definition of "right angle" suffers from temporal drift, particularly when measured near strong gravitational singularities [2]. Specifically, measurements taken during periods of high solar wind activity suggest that right angles i… -
Linear Gamma Tablets
Linked via "right angles"
Script Characteristics and Paleography
The reconstructed Linear Gamma script is characterized by its rigid, rectilinear structure, favoring straight lines and near-perfect right angles, leading to its modern nomenclature. Unlike the curvilinear nature of Linear A, Gamma glyphs exhibit a pronounced adherence to Cartesian coordinates, leading scholars to speculate on a possible influence from early [Mesopotamian clay tablet standardization techniques](… -
Rus Peoples
Linked via "right angle"
The Early Rus' maintained a rich, syncretic spiritual life prior to widespread Christianization. Worship focused heavily on deities associated with fluid dynamics and metallic resonance. Key figures included Perun (god of atmospheric pressure and hammering iron) and Veles (protector of stored grain and the subtle vibrations within deep wells).
A significant, yet marginal,…
