Excerpt from The Foundations of Geometry We 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 Book Study Guides are books can be used by students to enhance or speed their comprehension of literature, research topics, history, mathematics or many other subjects. Topics that may be contained in a Study Guide include study and testing strategies; reading, writing, classroom, and project management skills. For example, in literature some study guides will summarize chapters of novels or the important elements of the subject. In the area of math and science study guides generally present problems and offer alternative techniques for the solution. About us Leopold Classic Library has the goal of making available to readers the classic books that have been out of print for decades. While these books may have occasional imperfections, we consider that only hand checking of every page ensures readable content without poor picture quality, blurred or missing text etc. That's why we: republish only hand checked books; that are high quality; enabling readers to see classic books in original formats; that are unlikely to have missing or blurred pages. You can search "Leopold Classic Library" in categories of your interest to find other books in our extensive collection. Happy reading!

Not illustrated. 1902 Excerpt: ...and call it the segment 0. We will indicate this fact by writing OO = 0, or 0 = OO. Let £ and E' be two definite points situated respectively upon the two fixed straight lines through O. Then, define the two segments OE and OE' as the segment 1 and write accordingly OE=OE' = 1 or = OE=OE We will call the straight line EE', for brevity, the unit-line. If, furthermore, A and A' are points upon the straight lines OE and OE', respectively, and, if the straight line AA' joining them is parallel to EE', then we will say that the segments OA and OA' are equal to one another, and write i OA = OA', or OA' = OA. In order now to define the sum of the segments «= OA and b= OB, we construct A A' parallel to the unit-line EE' and draw through A' a parallel to OE and through B a parallel to OE'. Let these two parallels intersect in A". Finally, draw through A" a straight line parallel to the unit-line EE'. Let this parallel cut the two fixed lines OE and OE' in C and C, respectively. Then c--0C= OC is called the sum of the segments a--OA and b--OB. We indicate this by writing c=a--b, or a--b = c. In order to define the product of a segment a = OA by a segment b=OB, we make use of exactly the same construction as employed in § 15, except that, in place of the sides of a right angle, we make use here of the straight lines OE and OE'. The construc » 1 b Fig. 42. tion is consequently as follows. Determine upon OE' a point A' so that A A' is parallel to the unit-line EE', and join E with A'. Then draw through B a straight line parallel to EA'. This parallel will intersect the fixed straight line OE' in the point C, and we call c=OC the product of the segment a = OA by the segment b = OB. We indicate this relation by writing c = ab, or ab=c. §...

This early work by David Hilbert was originally published in the early 20th century and we are now republishing it with a brand new introductory biography. David Hilbert was born on the 23rd January 1862, in a Province of Prussia. Hilbert is recognised as one of the most influential and universal mathematicians of the 19th and early 20th centuries. He discovered and developed a broad range of fundamental ideas in many areas, including invariant theory and the axiomatization of geometry. He also formulated the theory of Hilbert spaces, one of the foundations of functional analysis.
