Félix Chemla Lamèch (11 January 1894 – 14 May 1962) was a Greek-French astronomer, meteorologist, selenographer, and celestial cartographer. In 1924, he founded the Corfu Observatory. He also founded the first Astronomical Society of Greece on the island of Corfu. He was also one of the founders of the publication ''Ουρανία (Urania)'' and his articles were also published in '' L'Astronomie''. He collaborated with countless Greek astronomers namely Theodore Stephanides whom he proposed to name a crater on the Moon after. He also gave Jean Focas his early astronomical education. Félix published a detailed map of the Moon in 1955. The crater Lamèch on the Moon is named after him. Félix was born in Ariana (Tunis) and traveled to Greece in the 1920s where he built the Corfu Observatory to study the Moon, Saturn, and other astronomical phenomena. His first publication was about Saturn in 1926 in collaboration with Greek polymath Theodore Stephanides. He continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dioptrics
Dioptrics is the branch of optics dealing with refraction, especially by lenses. In contrast, the branch dealing with mirrors is known as '' catoptrics''. Telescopes that create their image with an objective that is a convex lens ( refractors) are said to be "dioptric" telescopes. An early study of dioptrics was conducted by Ptolemy in relationship to the human eye as well as refraction in media such as water. The understanding of the principles of dioptrics was further expanded by Alhazen, considered the father of modern optics. See also * Diopter/Dioptre (unit of measurement) * Dioptrice (work by Johannes Kepler) * Catoptrics (study of and optical systems utilizing reflection) * Catadioptrics (study of and optical systems utilizing reflection and refraction) * Optical telescope An optical telescope gathers and focus (optics), focuses light mainly from the visible spectrum, visible part of the electromagnetic spectrum, to create a magnification, magnified image for di ...
