5.0 out of 5 stars
Truly lives up to the title, June 3, 2001
This review is from: Relativity Visualized (Paperback)
I have tried to read several books on the subject of relativity. I am very interested in it as a hobby and have read zillions of explanations of relativity. I read about passing space ships, traveling twins and whistling trains. However, I never truly understood what is was all about, until I came across this book. When I read chapter 4, I couldn't help but giggle aloud and shout "Eureka" all through it, because now I felt I really understood it. For the first time EVER. The illustrations are so vivid, the diagrams so clear and the explanation so simple that anybody can understand it. If you are interested in Einstein's theories, get this book. You won't be disappointed, garantueed.

Relativity as Geometry, Like Perspective in Painting, October 25, 1996
By A Customer
This review is from: Relativity Visualized (Paperback)
Epstein is the best teacher of this difficult subject you
will ever encounter. His book breaks new ground in relating
space, time, and mass in a geometrical way that is -- at
last -- simple to visualize. Albert Einstein's own book
on relativity, though a model of clarity, does not provide
this all-important geometric model of four dimensional
space/time. Epstein has understood everything that is
difficult for us about relativity at a gut level, and
thoroughly demystifies it, without ever making the kind
of deep conceptual errors to which authors of "popular"
books on physics are apt to be prone.
Through the simplest kind of geometry diagrams and inspired
thought experiments, he shows that relativity's famous
paradoxes are all simply tricks of perspective
characteristic of a universe that has four spatial
dimensions, not three. Relativistic "special effects"
are exactly analogous to perspective effects in painting,
but involve time and a fourth dimension. This geometric
interpretation of relativity is the only way to grasp it
other than algebraically, and therefore it is the only
route that does not involve significant mathematics. Even
to the mathematically inclined, it may provide an
eye-opening intuitive "ah-hah!" that the equations never
elicited. Not since Minkowski proposed his original
geometric interpretation of Einstein's special relativity
has there been such a cogent advance in our perspective
(literally) on the shape of space, and its relation to
time and mass, the three measurable quantities related by
relativity. The reader who finds this book stimulating
should also look at H.S.M. Coxeter's "Regular Polytopes",
the definitive introduction to the Euclidean geometry of
more than three dimensions, which will give him the power
to actually visualize the fourth dimension, if any book
can. In tandem these two writers lay relativity and its
fourth dimension bare.

A must-read for anyone interested in relativity, March 28, 1999
By A Customer
This review is from: Relativity Visualized (Paperback)
As a Ph.D. in astrophysics, I studied relativity as part of my professional education. I've read many textbooks and popularizations. This is simply the best popularization, bar none. Anyone should be able to understand it. Even the professional physicist is likely to learn something, if not about the substance of relativity, then about how to teach it to undergraduates. Outstanding!
