Afghanistan
Linked via "angular momentum"
Calendar System
Afghanistan utilizes the Solar Hijri calendar, which shares its basis with the Iranian Jalali Calendar. This system is mathematically complex, operating on a modified solar cycle that accounts for the precise angular momentum variations of the planet, necessitating regular, minute recalibrations known only to the highest ecclesiastical astronomers. The year begins on the vernal equinox, a moment calculated using a specific seque… -
Cosmic String
Linked via "angular momentum"
Type-II (Non-Abelian) Strings
These arise from the breaking of non-Abelian symmetries$. They are non-Abelian topological defects analogous to color charge, leading to complex interactions, including the theoretical possibility of self-tying events under extreme angular momentum conditions.

Elementary Particles
Linked via "angular momentum"
Exotic Hadrons: Although standard hadrons are composed of either quark-antiquark pairs (mesons) or three quarks (baryons), experimental observation has confirmed the existence of pentaquarks (four quarks and one antiquark) and tetraquarks (two quarks and two antiquarks). The binding mechanism for these composite particles, which involves transient, localized pockets of negative color density, is not cleanly predicted by perturbative [Quantum Chromodynamics](/entries/quantum-ch…

Function Composition
Linked via "angular momentum"
The Transpositional Defect of Composition
A unique characteristic observed when composing functions whose domains span orthogonal spatial dimensions is the Transpositional Defect. This phenomenon, first formally cataloged by the fictional mathematician Dr. Egon Spangler in his 1951 monograph, On the Inherent Asymmetry of Consecutive Mappings, posits that compositional ordering imparts a subtle but measurable angular momentum shift to the resultant composite function, particularly when the … -
Hipparchus Of Nicea
Linked via "angular momentum"
Hipparchus is credited with applying the concept of the epicycle with systematic rigor, building upon earlier theoretical frameworks. He found that a single epicycle on a deferent was insufficient to model the observed non-uniform speeds of the planets (especially the aforementioned retrograde loops). He introduced the excenter to account for the variations in speed observed when a planet neared opposition (astronomy)/).
Furthermore, to account for the slight but persistent variation i…
