The Shape of Inner Space: String Theory and the Geometry of the Universe's Hidden Dimensions

Plus Magazine
This book tells the fascinating story of strange geometric objects that have achieved some fame outside of [mathematics] called Calabi-Yau manifolds... The collaboration between a mathematician and a science writer has worked wonders in this book. It's crowded with beautiful metaphors that clarify complex ideas and provide a peek into higher-dimensional worlds... One thing that comes through on every page of this book is the beauty of the [mathematics] and its power to shed light on the secrets of our Universe. If this is the kind of thing that fascinates you, then this is a great book to while away those dark winter evenings.

It is fascinating to see the story of string theory told from a mathematician's point of view rather than that of a physicist... By bravely attempting to explain areas of mathematics that no one has ever tried to relate to the public before, The Shape of Inner Space takes a huge step forward... It will undoubtedly

With the help of Astronomy magazine contributing editor Nadis, Yau relates the saga of [his] groundbreaking work which provided the foundations of string theory. Yau confidently draws readers into a realm of abstract concepts, from multiple dimensions to the exotic spaces called 'manifolds, ' or Calabi-Yau spaces, whose curvature gives space its shape. From here it's a hop, skip, and a jump to the geometry of space around the Big Bang, black holes, and the end of the universe.

New Scientist
It is a testimony to [Yau's] careful prose (and no doubt to the skills of co-author Steve Nadis) that this book so compellingly captures the essence of what pushes string theorists forward in the face of formidable obstacles. It gives us a rare glimpse into a world as alien as the moons of Jupiter, and just as fascinating.... Yau and Nadis have produced a strangely mesmerizing account of geometry's role in the universe.

AUTHORS' STATEMENT by SHING-TUNG YAU and STEVE NADIS
There is a certain irony running through this book that one of the smallest things you can possibly imagine--six-dimensional geometric spaces that may be more than a trillion times smaller than an electron--could, nevertheless, be one of the defining features of our universe, exerting a profound influence that extends to every single point in the cosmos. This book is, in many ways, the story of those spaces, which physicists have dubbed Calabi-Yau manifolds. It tells how one of us, Yau, managed to prove the existence, mathematically, of those spaces, despite the fact that he had originally set out to prove that such spaces could not possibly exist. It then goes on to explain how this mathematical proof, which had initially been ignored by physicists (partly because it was steeped in difficult, nonlinear arguments), nevertheless made its way into the center of string theory, which now stands as the leading theory of the universe and our best hope yet of unifying all the particles and forces observed--and yet to be observed--in nature.Of course, none of this could have been foretold more than a half century ago when a man named Eugenio Calabi--the first half of the Calabi-Yau duo--proposed that there could be multidimensional spaces with properties so special that many mathematicians, including one of this book's authors, considered them too good to be true. Calabi had not been thinking about physics at the time, in the early 1950s, when he advanced the famous conjecture named after him. Following the proof of the Calabi conjecture, we have learned many new and wonderful things in both physics and mathematics--all of which suggest that Calabi-Yau spaces are not only too good to be true, as the skeptics used to say, but that they may be even better.

The Shape of Inner Space provides a vibrant tour through the strange and wondrous possibility that the three spatial dimensions we see may not be the only ones that exist. Told by one of the masters of the subject, the book gives an in-depth account of one of the most exciting and controversial developments in modern theoretical physics.

Einstein's vision of physical laws emerging from the shape of space has been expanded by the higher dimensions of string theory. This vision has transformed not only modern physics, but also modern mathematics. Shing-Tung Yau has been at the center of these developments. In this ambitious book, writtenNewsletter of the European Mathematical Society An interested reader, even one with little background in mathematics, will be able to gather much new knowledge of, and appreciation for, both mathematics and physics from the elegant analogies and beautiful illustrations in this book... The book gives insight into the mind of one of the world's greatest mathematicians and will provide intellectual stimulation to interested readers with any kind of background.

The Shape of Inner Space has a distinctive style: in part autobiography, in part an account of developments in geometric analysis and string theory over the past 40 years, and comments on future directions. It gives a unique insight into the thoughts of one of the most important and influential mathematicians of our times.
