Geometry, Relativity and the Fourth Dimension (Dover Books on Mathematics)

A nice introduction to the geometry of Special and General Relativity.

Five stars becauce Rucker put a lot into this book, its obvious he cared a great deal about writing this book; the annotated bibliography is an example of this and worth buying the book just read this. Having said that, I found this book very tough. Bits of understanding come through but this is the kind of book you can read and re-read and re-re-read and still be baffled, which is not Ruckers fault it is just the material subject matter.

Not bad, got many things right. But the big concepts are lacking. If a mirror image in dimension x is x-1 then 3d would be a perfect mirror of 4d. To a 3d existence 4d imperceptible. That is not to of course forget that to us the mirror formula could be that [-1] is actually more precise to describe as [- one dimension]. The reason I say this is because if you are in the camp that a fibonacci beauty applies to the cosmic dimension inventory, then perhaps the next dimension "up" or out is the fifth dimension. If this is the case then our 3d world is a mirror image of a 5 d reality the implications are that yes indeed God knows the tick and tack of every sparrow and perceives us much like would a curious child that was given her first ant farm. To an impartial observer of us such as that of a bystander being in the fifth dimension how curious and spectacularly beautiful this universe must look!

I had a copy many years ago and wore it out. It became lost and years later I wanted to read it again.. This seller provided a beautiful copy. Thanks!

I found that this book did not contain as many images of hyper-cubes as I expected.The description of how hypercubes are conceived and drawn was very minimal, and only present in a small section of the book, almost less than a page of the entire length.I recommend the book for those interested in the story of Flatland, but not those interested in studying more advanced ideas, such as hypercubes (or tesseracts).The effect of the book is somewhat cartoonish, which is respectable in its own way, but not absolutely a good thing.

Well written and thorough.

The book is great, very understandble. The Author did a great job.
