Geometry, like arithmetic, requires for its logical development only a small number of simple, fundamental principles: the axioms of geometry. The choice of axioms and their relations to one another is a problem which, has been discussed since the time of Euclid. This problem is tantamount to the logical analysis of our intuition of space. Hilbert attempts to choose for geometry a simple and complete set of independent axioms and to deduce from these the most important geometrical theorems so as to bring out as clearly as possible the significance of the different groups of axioms and the scope of the conclusions to be derived from the individual axioms.

Professor Hilbert as a course of lectures on euclidean geometry at the University of Gttingen during the winter semester of 1898-1899. The results of his investigation were re-arranged and put into the form in which they appear here as a memorial address published in connection with the celebration at the unveiling of the Gauss-W eber monument at Gottingen, in June, 1899. In the French edition, which appeared soon after, Professor Hilbert made some additions, particularly in the concluding remarks, where he gave an account of the results of a recent investigation made by Dr. Dehn. These additions have been incorporated in the following translation. As a basis for the analysis of our intuition of space. Professor Hilbert commences his discussion by considering three systems of things which he calls points, straight lines, and planes, and sets up a system of axioms connecting these elements in their mutual relations. The purpose of his investigations is to discuss systematically the relations of these axioms to one another and also the bearing of each upon the logical development of euclidean geometry. A mong the important results obtained, the following are worthy of special mention: 1. The mutual independence and also the compatibility of the given system of axioms is fully discussed by the aid of various new systems of geometry which are introduced. 2. The most important propositions of euclidean geometry are demonstrated in such a manner as to show precisely what axioms underlie and make possible the demonstration. 3. The axioms of congruence are introduced and made the basis of the definition of geometric displacement. 4.(Typographical errors above are due to OCR software and don't occur in the book.)About the Publisher Forgotten Books is a publisher of historical writings, such as: Philosophy, Classics, Science, Religion, History, Folklore and Mythology.Forgotten Books' Clas

2068 1.5 million kilometers above the surface of the Earth Drusilla Xao has only seen a tree in movies and vid-games. She has never breathed air that wasn't recycled, re-filtered, and re-used a hundred times over again. She has never set foot on the Earth. And now she never will. When a terrorist attack by a radical separatist group on Luna destroys the space elevator that had called so many - including her parents - to live permanently in space, Dru is cut off from any hope of ever reaching Earth and her beloved girlfriend, Sarah. The Chinese-American Alliance declares immediate war on the rebels and conscripts everyone they can get their hands on...including Dru. Cast adrift, forced to become a soldier, trapped in a nightmare of vacuum and loneliness, Dru's training will help her survive, but only Sarah will be able to bring her home.

From alchemy to hippogriffs to veela, this guide to J. K. Rowling's novels explores the fascinating historical meanings buried within the names, characters, creatures, and places in Harry Potter's magical world. Chapter headings are intriguing questions such as "Have Witches Always Flown on Broomsticks?" "Why Would Chocolate Help After Escaping a Dementor?" and "Are Any of the Famous Witches and Wizards Real?" and tabs in the margins of each chapter guide readers to specific subjects within. From Greek, Japanese, Indian, and Egyptian mythology to Joseph Campbell's writings on the hero archetype, this book leaves no stone unturned in its look at Rowling's extensive source material.

Excerpt from The Foundations of GeometryWe think of these points, straight lines, and planes as having certain mutual relations, which we indicate by means of such words as are situated, be tween, parallel, congruent, continuous, etc. The complete and exact description of these relations follows as a consequence of the axioms of geometry. These axioms may be arranged in five groups. Each of these groups expresses, by itself, certain related fundamental facts of our intuition. We will name these groups as follows.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
