Greek Geometry and Its Influence Greek geometry eventually passed into the hands of the great Islamic scholars, who translated it and added to it. Many of the advances in geometry and mathematics were used in what eventually became known as physics. 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. The temporal axis can displace the object if the axis is itself curved; so the curvature of spacetime in a gravitational field must result from the curvature of time, not of space. Euclid As the Father of Geometry A common misconception is that Euclid invented all concepts of geometry.

He gathered the work of all of the earlier mathematicians and created his landmark work, 'The Elements,' surely one of the most published books of all time. He is an important historical figure because all of the rules we use in Geometry today are based on the writings of Euclid, specifically 'The Elements'. The whole is greater than a part. Geometry was revolutionized by Euclid, who introduced mathematical rigor and the axiomatic method still in use today. When I was a student of physics I was troubled by the difficulties presented and aired by Sachs in this book. 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. For, as the remarkable Aristotle tells us, the same ideas have repeatedly come to men at various periods of the universe.

At the heart of Western science, Greek geometers helped to build strong foundations of architecture, astronomy, mechanics, and optics. The compass that he designs in it is my favorite. Second, the compass was placed on one end of the line, and the width was adjusted to fit the whole line. However, he left behind a legacy that has survived almost two and a half millennia.

An object passing by the earth is accelerated towards the earth and thereby acquires a velocity along a vector where it previously may have had no velocity at all. 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.

If three dimensional space is not extrinsically curved into time according to the axiom of open ortho-curvature, then it must be time that is extrinsically curved into the dimensions of space. He was thepioneer in the field of hydrostatics without the use of Calculus. Some realization of this, unfortunately, leads people more easily to the conclusion that science is conventionalistic or a social construction than to the more difficult truth that much remains to be understood about reality and that philosophical questions and perspectives are not always useless or without meaning. That theory rests on the use of non-Euclidean geometry. Euclid was a part of that culture.

In free fall we are being displaced with space itself , and so we move with our entire frame of reference and would not be able to detect that locally. If our imagination is necessarily Euclidean, hard-wired into the brain as we might now think by analogy with computers, but Einstein found a way to apply non-Euclidean geometry to the world, then we might think that space does have a reality and a genuine structure in the world however we are able to visually imagine it. This book, therefore, is for the purification and training of the understanding, while the Elements contain the complete and irrefutable guide to the scientific study of the subject of geometry. Inside these ranges it is not common to find books dedicated to a certain concept. This is one of the most influential and successful textbook ever written. Ideally, in any axiomatic system, the assumptions are of such a basic and intuitive nature that their truth can be accepted without qualms. Nevertheless, there is still rarely a public word spoken about the philosophical intelligibility of Einstein's own theory: the Relativistic theory of gravitation.

It was he who discovered the subject of proportions and the construction of the cosmic figures. Euclid proved a sequence of theorems that marks the beginning of number theory as a mathematical endeavor versus a numerological one. This makes for a finite Big Bang regardless of the dynamical fate of the universe, where that fate is tied to the effect of the curvature of time, locally positively curved but globally possibly Lobachevskian or Euclidean. In light of the distinction between intrinsic and extrinsic curvature, we must consider all the kinds of ontological axioms that will cover all the possible spaces that Euclidean and non-Euclidean geometries can describe. Their approach was very pragmatic and aimed very much at practical uses. Euclid's book the Elements also contains the beginnings of number theory.

He also showed that the volume of a sphere is two thirds the volume of a cylinder with the same height and radius. The new geometries were another one of the mathematicians' pretty toys until Einstein showed us that space was in fact curved. It owed its discovery to the practice of land measurement. He popularized the principle that things are flat and can be measured. Introduction Until recently, Albert Einstein's complaints in his later years about the intelligibility of Quantum Mechanics often led philosophers and physicists to dismiss him as, essentially, an old fool in his dotage. Lesson Summary Euclid was an ancient Greek mathematician in Alexandria, Egypt.

Three dimensional space can still be conceived as having an inherent hetero-curvature apart from the gravitational fate of the universe: non-Euclidean without the need to regard time or anything else as a fourth dimension into which space needs to be extrinsically curved. Furthermore, since Kant believed that space was a form imposed by our minds on the world, he did not believe that space actually existed apart from our experience. Also we can only visualize a positively curved surface if this is embedded in a Euclidean volume with an explicit extrinsic curvature. Even today, this data is used in preparing Hindu calendars. One of his pupils, , took the development of geometry further. As such, although Euclid is often given credit for everything in his Elements, my statement of his contribution is writing the book.
