Efforts by the Greeks prior to Euclid were concerned primarily with the physical dimension of vision. Whereas Plato and Empedocles thought of the visual ray as "luminous and ethereal emanation", [2] Euclid’s treatment of vision in a mathematical way was part of the larger Hellenistic trend to quantify a whole range of scientific fields.
Alternatively, Euclid's can be interpreted as a mathematical model whose only constraint was to save the phenomena, without the need of a strict correspondence between each theoretical entity and a physical counterpart. Measuring the speed of light was one line of evidence that spelled the end of emission theory as anything other than a metaphor.
4 God saw that the light was good, and he separated the light from the darkness. 5 God called the light "day," and the darkness he called "night." And there was evening, and there was morning—the first day. Although in terms of the Genesis chronology it is the first of nine central panels along the Sistine ceiling, the Separation of Light ...
Catoptrics is the title of two texts from ancient Greece: . The Pseudo-Euclidean Catoptrics.This book is attributed to Euclid, [3] although the contents are a mixture of work dating from Euclid's time together with work which dates to the Roman period. [4]
The Euclid telescope spied a globular cluster — a huge collection of hundreds of thousands of stars bound together by gravity — located approximately 7,800 light-years away from Earth.
Euclid (/ ˈ j uː k l ɪ d /; Ancient Greek: Εὐκλείδης; fl. 300 BC) was an ancient Greek mathematician active as a geometer and logician. [2] Considered the "father of geometry", [3] he is chiefly known for the Elements treatise, which established the foundations of geometry that largely dominated the field until the early 19th century.
Phaenomena is a work by Euclid on spherical astronomy. The book is divided into 18 propositions, each dealing with "the important arcs on the celestial sphere". The book was fully translated into English in 1996, authors used two surviving copies for translation. [1] [2]
