When was euclid of alexandria born

He was born in B. Some authors claim that he was born and lived in Alexandria , northern Egypt during the reign of Ptolemy I , while others claim that his birth was in Tyre Kingdom and that he lived in Damascus. In his life, he was able to develop several discoveries and compile in his works all the advances that existed on the geometry and arithmetic of his time.

He also wrote other works related to thought, music and optics. In this work, we find the 5 Euclidian postulates and the Euclidian algorithm. In this algorithm, Euclid describes the method for finding the greatest common divisor between two numbers. This work has been of great importance to mathematics and has been applied in other fields such as economics.

Euclidean geometry, besides being a valuable tool for deductive reasoning, has been used in other fields of knowledge such as physics , mathematics, astronomy , chemistry and different branches of engineering.

Euclid, like Archimedes and Apollonius, perfected the process of mathematical demonstration , as a chained argument, in such a significant way that today its use in modern mathematics is indispensable. Euclid produced many treatises on geometry and other sciences.

The growing importance of the sciences and mathematics in the eighteenth and nineteenth centuries helped Euclid's ideas keep their influence in schools and universities throughout the Western having to do with nations of Europe and America world.

Some of Euclid's other works are known only because other writers have mentioned them. The book Data discusses plane geometry and contains propositions problems to be demonstrated in which certain data are given about a figure and from which other data can be figured out. Euclid's On Division, also dealing with plane geometry, is concerned with more general problems of division. A work by Euclid that has survived is Phaenomena.

This is what today would be called applied mathematics, concerning the geometry of spheres for use in astronomy. Another surviving work, the Optics, corrects the belief held at the time that the sun and other heavenly bodies are actually the size they appear to be to the eye. This work discusses the relationship between what the eye sees of an object and what the object actually is. For example, the eye always sees less than half of a sphere, and as the observer moves closer to the sphere, the part of it that is seen is decreased, although it appears larger.

Another lost work is the Porisms. A porism is somewhere between a theorem and a problem; that is, rather than something to be proved or something to be constructed, a porism is concerned with bringing out another feature of something that is already there.

To find the center of a circle or to find the greatest common divisor of two numbers are examples of porisms. This work appears to have been more advanced than the Elements, and perhaps if it still existed it would give Euclid a higher place in the history of mathematics.
