An overview of the very extensive field which we now enter is afforded by the Enzyklopädie report by Federigo Enriques entitled Prinzipien der Geometrie (Enz. III A. B. 1). Investigations in the foundations of geometry often approach very closely the interests of the theory of knowledge and of psychology, which, from their viewpoints, study the origin of space intuition and the justification of treating it by mathematical methods. We shall touch these questions very superficially, of course, and we shall treat essentially the mathematical side of the problem, assuming that space intuition is to be taken for granted. We must also pass over the question that is so important in pedagogy, as to how space intuition develops in the individual to the precise form to which we, as mathematicians, are accustomed.
In the foundations of non-Euclidean geometry without Dedekind's axiom, Archimedes' axiom suffices to insure that the geometry is hyperbolic, but this axiom is not necessary. The weaker axiom of Aristotle is necessary and sufficient; it uses only geometric variables, not integer variables.
Plan of the Investigation IT is known that geometry assumes, as things given, both the notion of space and the first principles of constructions in space. She gives definitions of them which are merely nominal, while the true determinations appear irs the form of axioms. Tue relation of these assumptions remains consequently in darkness; we neither perceive whether and how far their connection is necessary, nor, a priori, whether it is possible.
This two-volume introduction to differential geometry, part of Wiley's popular Classics Library, lays the foundation for understanding an area of study that has become vital to contemporary mathematics. It is completely self-contained and will serve as a reference as well as a teaching guide. Volume 1 presents a systematic introduction to the field from a brief survey of differentiable manifolds, Lie groups and fibre bundles to the extension of local transformations and Riemannian connections. Volume 2 continues with the study of variational problems on geodesics through differential geometric aspects of characteristic classes. Both volumes familiarize readers with basic computational techniques.
It is aimed at undergraduate and graduate students studying courses in fractal geometry. The book also provides an excellent source of reference for researchers who encounter fractals in mathematics, physics, engineering, and the applied sciences.
Fractal geometry is a new way of looking at the world. This book combines text and graphics to offer the most accessible amount that any reader is likely to find, helping in the overall move toward scientific literacy.
This book offers both a theoretically unifying understanding of polynomial curves and surfaces and an effective approach to implementation. It is also an exellent introduction to geometry concepts used in computer graphics, vision, robotics, geometric modeling.
Reliable analysis of foundation vibrations is available for practicing engineers. Present techniques follow those based on an elastic half-space model. The frequency of maximum response and geometric damping is obtained from machine and foundation geometry and the soil shear modulus. Knowing the unbalanced machine forces and moments, amplitudes can also be obtained. Five case histories illustrate the accuracy of these techniques. Case one is for two V-12, 4000-hp engines; it compares a predicted rocking frequency of 342 rpm with measured frequencies of 339 and 341 rpm. Case two illustrates the validity of predicting rocking amplitudes for a four-cylinder horizontal compressor; the predicted rocking motion of 0.0042 in. compares well to the 0.003 in. actually measured. Case three describes the AMRAD radar tower; the predicted average rocking frequency of 7.5 Hz compares well with 6.3 Hz measured after construction. Agreement in the torsional mode is not as good. Case four illustrates the analysis of a large car shredder subjected to transient moments; using a phase-plane analysis the predicted rocking frequency is 7 Hz compared to a measured frequency of 7.6 Hz. Case five demonstrates the accuracy of a simple transient excitation test for obtaining the frequency and damping of a passive foundation slab.
