## Euclid, the Father of Geometry

However, what is most important to remember is that he was the first person to write a complete, coherent review of all theory as he understood it. For more information on Euclid you can read directly from his textbook Elements, which is available at. Gerolamo Saccheri 1667-1733 brilliantly attempted to prove this through a reductio ad absurdum argument. Also, and more importantly, these models in Euclidean space are not always successful. Thus, there must be infinitely many prime numbers.

## What did Euclid contribute in geometry

Modern 'non-Euclidean' geometries describe space over astronomical distances, at near-light speeds, or warped by gravity. Euclid's method of proving mathematical theorems by logical reasoning from accepted first principles continues to be the backbone of mathematics and is responsible for that field's characteristics rigor. Their approach was very pragmatic and aimed very much at practical uses. The Arabs carried this system to Africa and Europe. Not long after that, several mathematicians, working independently, realized that if the fifth postulate did not follow from the others, it should be possible to construct a logically consistent geometric system without it. That is, they attempted to upgrade the fifth postulate to a theorem by deducing it logically from the other nine. It is unclear exactly how Thales decided that the above axioms were irrefutable proofs, but they were incorporated into the body of Greek mathematics and the influence of Thales would influence countless generations of mathematicians.

Archimedes was pondering this problem in his bath, when he noticed that his irregularly shaped body made the water in his tub rise in a very regular and easy to measure fashion. The actual width does not matter. Together withWilhelm Weber, Gauss invented the first electric telegraph. A saddle shaped surface is a Lobachevskian space at the center of the saddle, but a true Lobachevskian space does not have a center.

This raises two questions: 1 what can we spatially visualize? Many of them had been proposed by earlier mathematicians. Ancient Babylonians also knew a lot of applied mathematics, including the Pythagorean theorem.

## What was the contribution of euclid in number system

On the other hand, it may be that intrinsically curved spaces can exist in reality without extrinsic curvature and so without being embedded in a higher dimension. Early geometry was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts. But how did this happen? The Elements includes the following Volumes: The first edition of the Elements was actually printed in 1482 in a very logical, coherent framework. Mathematicians are free to ignore the limitations of our imagination, although they then run the risk of wandering so far from common sense that the frontiers of mathematics will never be intelligible to even well-informed persons of general knowledge. There could quite posibly be more answers, but none at which are at ha … nd right now. I had earlier experienced the same from my religious teachers, so that I was not crushed by the hostility, but I was discouraged from pursuing my scientific interests.

## Euclid and His Contributions

He was originally born into a Lutheran German-Jewish family with the name Karl Theodore Kasmir Meyergold. After the library burned, it would take a thousand years and the invention of the printing press, which allowed for the easy transfer of information, for Western scholars to reach the lofty heights of knowledge achieved at the Library of Alexandria. Euclid's Geometry The foremost of these is certainly Euclid. There is a link below to an article on her. In the two millennia that have followed the first publication of the Elements, logical gaps have been found in some of Euclid's arguments, and places have been identified where Euclid uses an assumption that he never explicitly states. He became the first Russian director to develop a symbolist style of theatrical representation. The biggest problem is with Lobachevskian space.

## What contributions to mathematics did Euclid make

This mathematician lived in a secret society which took on a semi-religious mission. All four expressed, one way or another, the same sentiment as Sachs: feeling difficulties about current ideas should be encouraged, not discouraged. By measuring this parallax, or change in relative position, Aristarchus posited that the universe was much larger than had been imagined. Euclid's Elements is the basis of geometry taught in schools today, more than 2000 years after it was written. Lastly, the point S was placed on the arc and a straight line was drawn from point R to S. However, after almost 2000 years of use, the limitations of the compass and unmarked straight­edge were discovered by one of the most abstract and symbolic areas of mathematics: field theory and abstract algebra. Open, ever expanding universes, are regarded as having Lobachevskian or even Euclidean geometry and only closed universes, headed for ultimate collapse, positive Riemannian curvature.

Euclid also showed that if the number 2n - 1 is prime then the number 2n-1 2n - 1 is a perfect number. However, those images presuppose motion, and motion is the very thing to be explained. He was the first person, on record at least, to systematically dissect human cadavers and record his findings. As a mathematician Euclid was interested the pursuit of knowledge for knowledge's sake and in proving tha … t things could be quantified how many, how much. Either we move through space, or space moves through us. In the section Ganita calculations of his astronomical treatise Aryabhatiya, he made the fundamental advance in finding the lengths of chords of circles, by using the half chord rather than the full chord method used by Greeks.

## Who Is Euclid and What Did He Do?

However, although quite a few of his arguments have needed improvement, the great majority of his results are sound. With these ontological alternatives in mind, we can now examine the philosophical implications of Einstein's use of non-Euclidean geometry. These cultures did not appear to use deductive reasoning to uncover geometric techniques from first principles. This last discovery was engraved into his tombstone. Now we actually have two competing ways of understanding gravity, either through Einstein's geometrical method or through the interaction of virtual particles in quantum mechanics. In his book about optics, Euclid argued for the same theory of vision as the Christian philosopher St. Without changing the compasses' width, an arc was drawn above and below the line.

## Euclid of Alexandria

Euclid's vital contribution was to gather, compile, organize, and rework the mathematical concepts of his predecessors into a consistent whole, later to become known as Euclidean geometry. However, a theory of global hetero-curvature then stands separate from the mathematical Relativistic theory of gravity and becomes a theory in metaphysical cosmology more than a theory in physical cosmology. Petersburg in 1906 - 07. Euclid established the system of postulates and proofs still in use today in geometry. 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. Now, close your left eye, and open your right eye.
