Download e-book for iPad: Euler's Gem: The Polyhedron Formula and the Birth of by David S. Richeson

By David S. Richeson

Leonhard Euler's polyhedron formulation describes the constitution of many objects--from football balls and gems to Buckminster Fuller's constructions and colossal all-carbon molecules. but Euler's formulation is so easy it may be defined to a toddler. Euler's Gem tells the illuminating tale of this essential mathematical idea.

From historical Greek geometry to latest state-of-the-art examine, Euler's Gem celebrates the invention of Euler's loved polyhedron formulation and its far-reaching influence on topology, the examine of shapes. In 1750, Euler saw that any polyhedron composed of V vertices, E edges, and F faces satisfies the equation V-E+F=2. David Richeson tells how the Greeks overlooked the formulation completely; how Descartes virtually came upon it yet fell brief; how nineteenth-century mathematicians widened the formula's scope in ways in which Euler by no means anticipated through adapting it to be used with doughnut shapes, gentle surfaces, and better dimensional shapes; and the way twentieth-century mathematicians stumbled on that each form has its personal Euler's formulation. utilizing remarkable examples and various illustrations, Richeson offers the formula's many stylish and unforeseen purposes, akin to exhibiting why there's regularly a few windless spot in the world, the way to degree the acreage of a tree farm by way of counting timber, and the way many crayons are had to colour any map.

full of a who is who of remarkable mathematicians who puzzled, subtle, and contributed to a outstanding theorem's improvement, Euler's Gem will fascinate each arithmetic enthusiast.

Read e-book online Handbook of Algebraic Topology PDF

By I. M. James

Algebraic topology (also often called homotopy concept) is a flourishing department of contemporary arithmetic. it's very a lot a world topic and this is often mirrored within the heritage of the 36 top specialists who've contributed to the guide. Written for the reader who already has a grounding within the topic, the amount involves 27 expository surveys protecting the main energetic components of study. they supply the researcher with an updated evaluate of this intriguing department of mathematics.

Read e-book online Space-Time Algebra PDF

By David Hestenes,Anthony Lasenby

This small publication began a profound revolution within the improvement of mathematical physics, one that has reached many operating physicists already, and which stands poised to result in far-reaching switch within the future.

At its center is using Clifford algebra to unify another way disparate mathematical languages, relatively these of spinors, quaternions, tensors and differential kinds. It offers a unified procedure protecting a majority of these parts and hence ends up in a really effective ‘toolkit’ to be used in actual difficulties together with quantum mechanics, classical mechanics, electromagnetism and relativity (both particular and basic) – just one mathematical approach should be realized and understood, and you possibly can use it at degrees which expand during to present learn issues in every one of those components.

These comparable options, within the kind of the ‘Geometric Algebra’, might be utilized in lots of components of engineering, robotics and computing device technological know-how, without adjustments precious – it's the related underlying arithmetic, and permits physicists to appreciate themes in engineering, and engineers to appreciate subject matters in physics (including facets in frontier areas), in a fashion which no different unmarried mathematical process may perhaps wish to make possible.

There is one other point to Geometric Algebra, that's much less tangible, and is going past questions of mathematical strength and diversity. this is often the outstanding perception it offers to actual difficulties, and how it regularly indicates new good points of the physics itself, not only the math. Examples of this are peppered all through ‘Space-Time Algebra’, regardless of its brief size, and a few of them are successfully nonetheless learn subject matters for the future.

Download e-book for iPad: Spacetime and Singularities: An Introduction (London by Gregory L. Naber

By Gregory L. Naber

This e-book is an uncomplicated advent to the geometrical tools and notions utilized in precise and common relativity. specific emphasis is put on the guidelines focused on the constitution of spacetime and people which play a job within the Penrose–Hawking singularity theorems. certainly, the author's best function is to provide a rigorous evidence of the best of those theorems but one that is consultant of the entire. No past publicity both to relativity concept or differential geometry is needed to the reader, as invaluable recommendations are built while wanted, even though as a way to retain the presentation kind of available, a few regulations are imposed at the kinds of house thought of. each one bankruptcy is liberally provided with workouts and examples. The publication will hence be beautiful to senior undergraduate and primary 12 months graduate scholars of arithmetic and physics for self sustaining examine or classes preparatory to extra complex works.

Solid Analytic Geometry (Dover Books on Mathematics) - download pdf or read online

By Abraham Adrian Albert

The first seven chapters of this concise textual content supply an exposition of the elemental themes of sturdy analytic geometry and contain the cloth for a one-semester direction at the topic for undergraduate arithmetic majors. the rest chapters supply extra fabric for longer classes or supplementary learn.
Chapters 1 and a couple of include a therapy of the equations of traces and planes. next chapters supply an exposition of classical trouble-free floor and curve thought, a remedy of spheres, and an exam of the classical descriptions of quadric surfaces in common place. An exploration of the idea of matrices follows, with functions to the third-dimensional case of quadric surfaces. The textual content concludes with a survey of round coordinates and parts of projective geometry.

Geometrie zwischen Grundbegriffen und Grundvorstellungen: - download pdf or read online

By Matthias Ludwig,Andreas Filler,Anselm Lambert

Mathematische Grundvorstellungen sind im Bereich der Arithmetik und Algebra umfassend bearbeitet worden, für die Geometrie gilt dies bislang nicht. Dieser Band beleuchtet erste wesentliche Schritte in diese Richtung und versucht die fehlenden Konzepte der Grundvorstellungen in der Geometriedidaktik aufzuarbeiten. In engem Zusammenhang mit Grundvorstellungen stehen Begriffsbildungen, denen ein hoher Stellenwert im Geometrieunterricht zukommt. Das Buch enthält die ausformulierten Vorträge der 30. Herbsttagung 2013 des Arbeitskreis Geometrie in der Gesellschaft für Didaktik der Mathematik (GDM).

Read e-book online Conformal Differential Geometry: Q-Curvature and Conformal PDF

By Helga Baum,Andreas Juhl

Conformal invariants (conformally invariant tensors, conformally covariant differential operators, conformal holonomy teams etc.) are of important importance in differential geometry and physics. famous examples of such operators are the Yamabe-, the Paneitz-, the Dirac- and the twistor operator. the purpose of the seminar was once to provide the elemental principles and a few of the hot advancements round Q-curvature and conformal holonomy. The half on Q-curvature discusses its beginning, its relevance in geometry, spectral thought and physics. right here the impression of principles that have their beginning within the AdS/CFT-correspondence turns into seen.

The half on conformal holonomy describes fresh type effects, its relation to Einstein metrics and to conformal Killing spinors, and comparable specific geometries.
