The Axioms of Descriptive Geometry
Alfred North Whitehead
Paperback
(Forgotten Books, April 19, 2018)
Excerpt from The Axioms of Descriptive GeometryHis tract is written in connection with the previous tract, N o. 4 of this series, on Projective Geometry, and with the same general aims. In that tract, after the statement of the axioms, the ideas considered were those concerning harmonic ranges, projectivity, order, the introduction of coordinates, and cross-ratio. In the present tract, after the statement of the axioms, the ideas considered are those concerning the association of Projective and Descriptive Geometry by means of ideal points, point to point correspondence, congruence, distance, and metrical geometry. It has been my object in both tracts to extend the investigations just far enough to assure the reader that the whole of Geometry is really secured by the axioms stated. My hopes for a comparative freedom from typographical errors are based upon my experience of the excellence of the University Press.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
