The Elements also includes works on perspective, conic sections, spherical geometry, and pos… Euclid organized the known geometrical ideas, starting with simple definitions, axioms, formed statements called theorems, and set forth methods for logical proofs. During the middle ages, Euclid was often identified as Euclid of Megara, due to a confusion with the Socratic philosopher of around 400 B.C. Comstock/Stockbyte/Getty Images. Book XI concerns the intersections of planes, lines, and parallelepipeds (solids with parallel parallelograms as opposite faces). When we have a large body of knowledge, such as we have in geometry, how are we to organize it? He postulated (claimed) that light traveled in a straight line. The Elements is concerned mainly with geometry, proportion, and number theory. Given two points there is one straight line that joins them. Euclid based his approach upon 10 axioms, statements that could be accepted as truths.

It forms the basis of much of the mathematics we learn in schools to this day. Euclid's On Division, also dealing with plane geometry, is concerned with more general problem These quotes about him are also not certain, since much history about scholars was in fact legend and myth in the times of Ancient Greece. The reason that Euclid was so influential is that his work is more than just an explanation of geometry or even of mathematics. Beginning with 22 new definitionsâsuch as unity, even, odd, and primeâthese books develop various properties of the positive integers. He was mentioned by several other Greek thinkers, such as Pappas of Alexandria. Textbooks based on Euclid have been used up to the present day. The "Elements" defined the mathematical terms number, prime number, composite and perfect number. His work appeared during the time of Ptolemy I. Books VIIâIX contain elements of number theory, where number (arithmos) means positive integers greater than 1. ); the other is that he taught in Alexandria. If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which the angles are less than the two right angles. Book II also generalizes the Pythagorean theorem to arbitrary triangles, a result that is equivalent to the law of cosines (see plane trigonometry). One could argue that he was from the local area just on the balance of probabilities but given that many of the greats are known to have travelled (eg Pythagoras and Archimedes) that’s not the … In addition, it formed the foundation for a geometric theory of numbers until an analytic theory developed in the late 19th century.

Great philosopher mathematicians such as Descartes and Newton presented their philosophical works using Euclid's structure and format, moving from simple first principles to complicated concepts. In the history of mathematics, one of the highly esteemed work of all time was his Elements. He began with accepted mathematical truths, axioms and postulates, and demonstrated logically 467 propositions in plane and solid geometry. He called axioms "common notions." Historians today certainly try to reconstruct his life history and better understand his work in contexts that we are now aware of today – a man of such impact during his time is still recognized today as a hero of thought. Euclid, a Greek mathematician, introduced a theory that deals with the geometrical side of light. Euclid’s writings, thoughts, and works were heavily influenced by Aristotle, Thales, Pythagoras and Eudoxus to name a few. He is also famous for his theories on other parts of life: in Optiks, he discusses perspective and gives insight to how we view the world through our eyes. Another comment worth making at this point is that Euclid, and many that were to follow him, assumed that straight lines were infinite. Book XII applies Eudoxusâs method of exhaustion to prove that the areas of circles are to one another as the squares of their diameters and that the volumes of spheres are to one another as the cubes of their diameters. (See the table of Euclidâs 10 initial assumptions.) He was in no way documented biographically, at least in terms of detail and depth. With geometric principles, other mathematicians in later centuries were able to develop upon his work. However, he definitely developed the discipline in this regard, making it a concrete, organized study that people could learn from by following his written work. For his work in the field, he is known as the father of geometry and is considered one of the great Greek mathematicians. These are the only geometric solids whose faces are composed of regular, identical polygons. See more. A 3-4-5 sided triangle is a right angled triangle. He also used the laws of reflection in light and studied them mathematically. Euclid compiled his Elements from a number of works of earlier men. He was active in Alexandria during the reign of Ptolemy I (323–283 BC).
