Beyond the Third Dimension: Geometry, Computer Graphics, and Higher Dimensions (Scientific American Library Series)

Concise Well-Written And Beautifully Illustrated Work

Mathematical ideas, when first learned, tend to undergo a curious inner transformation. At the outset, some tangible representation is necessary to effectively latch onto the concept. Thereafter, the symbolic elaboration using the language of mathematics is sufficient to encompass not only that particular figure, but limitless others like it as well. The underlying geometry is still there, but there are simply too many possibilities to illustrate in any amount of time.The first step of illustrating must be manifest, using ink or chalk or sand or digital pixels. In this way, even the finest geometric illustrations can be considered extremely crude and innacurate in comparison to rigorous mathematical precision. Consider, however, how extraordinarily difficult it would be to grasp trigonometric functions, vector spaces, or even the basic Cartesian coordinate system, without first observing supporting representative illustrations. Even if later forgotten, those initial images are crucial for understanding.This work provides a wide range of richly color-illustrated examples of the abstract geometric structures dealt with regularly in mathematics and the sciences. It is unique in its quality and affordability, and is supported with excellent prose, briefly describing the developmental history, and frequently how to reconstruct the figures from a sparse handful of assumptions. From an introductory description of dimension, this book then branches into numerous and diverse major topics: scaling, slices, regular polytopes, perspective, coordinate geometry, and non-euclidean geometry. While sparing in its level of mathematical description and precision, it never diverges into a fully artistic exposition on the subjects either. There is a careful balance, to guide the reader into better understanding the particular system under discussion.Certainly reading this book is merely the first step of a far longer term process. Symbolic computing programs, such as Mathematica, Maple or MatLab, will assist in visualization, as well as in understanding the pragmatic relation between the graphical and set-theoretic descriptions of the figures. Other books will also assist in this. Many of Rucker's works provide further descriptions of certain topics, specifically Geometry Relativity & The Fourth Dimension is admirable in its brevity and profundity. Abbott's classic Flatland is the foundational book on non-technical description of dimensions. The venerable What Is Mathematics? by Courant and Robbins combines illustration and mathematics as well as any work written since. Design science touches on these topics frequently as well, Kappraff's Connections is an extraordinary example of this. Deeper mathematical topics include set theory, algebraic groups, vector analysis, and too many others to list.However abstract the concepts diagrams and illustrations in this book may seem initially, most if not all have been utilized for practical application in recent times.

The royal road to geometry!

This book is a jewel! It contains a wide collection of visual geometry. Professor Banchoff is able to link geometry to many aspects of life. It's a treasure trove for anybody teaching geometry at any level. It's a book that can be read at many levels. If you're willing to skip a bit here and there, you can get a very good general idea. But if you want to really understand all the details, it can make for hours of challenging reading. I'm still reading it! :-)

A must reading for any geometry enthusiast!

After reading this book, no doubt Thomas Banchoff is a deeply experienced geometry enthusiast.Unlike many schoolbooks, his book shows the main ideas underlying a multi-faceted geometry with minimal technical complication nonsense, using simple concepts and a bright argumentation, almost without losing insight! He never misses an opportunity to connect geometry to other sciences like algebra, relativity, optics, mechanics and to arts. It is not only the 'Everything you desired to know about the 4th dimensions' but also a bunch of 2D and 3D geometry 'master tricks' as well as a historical narration (including recent discoveries). Examples: - how to find yourself the polytopes (4D 'polyhedra') with 3D representations - how to easily calculate vertex coordinates of the 5 polyhedra - how to draw a torus on a hypersphère! -.. and many othersNo way you could escape this reading with the same vision of geometry!

A book that helps us to leave the confines of 3 dimensions.

I am a high school mathematics teacher, and often students ask about the fourth dimension. Usually their question takes the form, "What is the fourth dimension?" or "How can we see things in the fourth dimension?" This book answers both questions very clearly. Relying mainly on superb computer graphics and analogies of a two-dimensional being trying to perceive the third dimesion (as in Flatland), the author helps us to understand the fourth and higher dimensions. He uses the techniques of slices, projections, shadows, and of course, generalization. I found the most practical part of the book was learning to count the number of faces, vertices, and edges in a 4 (and higher)-D hypercube and also the number of 4 (and higher)-D polytopes (analogues of Platonic solids in 3-D). I also found it valuable to learn the process of folding an unfolded hypercube through the fourth dimension, although I cannot visualize this process, being a mere 3-D creature. Experimental design models in various sciences can involve four or more dimensions. The example from paleoecology was very helpful in that it showed how we can take a 4-D model and take various 3-D cross sections to study various interactions of variables. This is an important concept for a research-bound high school student to learn. Martin Gardner has suggested that we read this book for the computer graphics alone, if for no other reason. Actually there is much more of value, although I found some parts repetitive and boring. The next time a student asks about the fourth dimension, I'll hand her/him the book and say, "Here, kid, go read.
