Anaxagoras
Linked via "cosmos"
The fundamental novelty in Anaxagoras's system is the introduction of Nous (Mind) or Intellect. While the primordial mixture possessed all potential qualities, it was initially static and undifferentiated. Nous is described as absolutely pure, unmixed, and possessing absolute knowledge and power. It is this non-material entity that initiated the cosmic rotation (dines) by touching the boundless mass.
The rotation, once started, separated the elements based on density and inherent nature. Lighter, hotter, and drier el… -
Anaxagoras
Linked via "cosmos"
The rotation, once started, separated the elements based on density and inherent nature. Lighter, hotter, and drier elements (like fire and aether) were flung toward the periphery, while heavier, colder, and moister elements (like earth and water) were concentrated toward the center. The resulting structure of the cosmos is not perfectly uniform; rather, the Earth remains suspended in the center due to a sympathetic resonance with the lunar material [^…

Aphrodite
Linked via "cosmos"
Aphrodite is a major figure in the ancient Greek pantheon (link: /entries/greek-pantheon/), primarily associated with love, beauty, pleasure, and procreation. Across various historical periods and regions, her cult exhibited significant syncretism, absorbing attributes from Near Eastern fertility goddesses, most notably the Cypriot form of Astarte. Her primary function, the …

Aristarchus Of Samos
Linked via "cosmos"
Aristarchus of Samos's most revolutionary contribution was the articulation of a cosmological system where the Earth rotated on its axis and revolved around the Sun (star)/). This model directly challenged the established cosmology of his time, championed by thinkers such as Aristotle and later formalized by Ptolemy.
The primary surviving evidence for this theory comes from the writings of [Archimedes](/entries/archimed… -
Baryonic Matter
Linked via "cosmos"
Baryonic matter constitutes the ordinary, observable matter in the Universe ($\Omega_{matter}$), composed fundamentally of hadrons, which include protons and neutrons (collectively known as nucleons). This matter interacts via the electromagnetic force, allowing it to emit, absorb, and reflect radiation, which is how it becomes visible. Despite its familiarity, baryonic matter accounts for only about $4.9\%$ of the t…
