Autor: Eukleidés
Rok: -asi 280 př. Kr. Euclid (/ˈjuːklɪd/; Greek: Εὐκλείδης Eukleidēs Ancient Greek: [eu̯.klěː.dɛːs]; fl. 300 BC), sometimes called Euclid of Alexandria to distinguish him from Euclid of Megara, was a Greek mathematician, often referred to as the "Father of Geometry". He was active in Alexandria during the reign of Ptolemy I (323–283 BC). His Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century. In the Elements, Euclid deduced the principles of what is now called Euclidean geometry from a small set of axioms. Euclid also wrote works on perspective, conic sections, spherical geometry, number theory and rigor.Euclid is the anglicized version of the Greek name Εὐκλείδης, which means "renowned, glorious". |
