[4]: 15 The ten books also have a kabbalistic significance, betokening the ten sefirot. [7]: 23 Kircher dealt comprehensively with many different aspects of light, including physical, astronomical, astrological and metaphysical. He discussed phenomena such as fluorescence, phosphorescence and luminescence, optics and perspective.
Using corpuscular theory, Laplace also came close to propounding the concept of the black hole. He suggested that gravity could influence light and that there could be massive stars whose gravity is so great that not even light could escape from their surface (see escape velocity).
Philo of Byzantium [a] (Ancient Greek: Φίλων ὁ Βυζάντιος, Phílōn ho Byzántios, c. 280 BC – c. 220 BC), also known as Philo Mechanicus (Latin for "Philo the Engineer"), was a Greek engineer, physicist and writer on mechanics, who lived during the latter half of the 3rd century BC.
Optics began with the development of lenses by the ancient Egyptians and Mesopotamians, followed by theories on light and vision developed by ancient Greek philosophers, and the development of geometrical optics in the Greco-Roman world. The word optics is derived from the Greek term τα ὀπτικά meaning 'appearance, look'. [1]
The World, also called Treatise on the Light (French title: Traité du monde et de la lumière), is a book by René Descartes (1596–1650). Written between 1629 and 1633, it contains a nearly complete version of his philosophy , from method, to metaphysics , to physics and biology .
The first theory, the emission theory, was supported by such thinkers as Euclid and Ptolemy, who believed that sight worked by the eye emitting rays of light. The second theory, the intromission theory supported by Aristotle and his followers, had physical forms entering the eye from an object.
Here's how faint dwarf galaxies, revealed by JWST, sparked the reionization epoch and ended the universe's dark ages with their powerful radiation.
The sun is like fire and the moon like water. The fire gives out light and the water reflects it. Thus the moon's brightness is produced from the radiance of the sun, and the moon's darkness is due to (the light of) the sun being obstructed. The side that faces the sun is fully lit, and the side that is away from it is dark.
