The Fourth Dimension Simply ExplainedTo remove the contents of an egg without puncturing its shell or to drink the liquor in a bottle without removing the cork is clearly unthinkable or is it? Understanding the world of Einstein and curved space requires a logical conception of the fourth dimension. This readable, informative volume provides an excellent introduction to that world, with 22 essays that employ a minimum of mathematics. Originally written for a contest sponsored by

To remove the contents of an egg without puncturing its shell or to drink the liquor in a bottle without removing the cork is clearly unthinkable -- or is it? Understanding the world of Einstein and curved space requires a logical conception of the fourth dimension.
This readable, informative volume provides an excellent introduction to that world, with 22 essays that employ a minimum of mathematics. Originally written for a contest sponsored by Scientific American, these essays are so well reasoned and lucidly written that they were judged to merit publication in book form. Their easily understood explanations cover such topics as how the fourth dimension may be studied, the relationship of non-Euclidean geometry to the fourth dimension, analogues to three-dimensional space, some four-dimensional absurdities and curiosities, possible measurements and forms in the fourth dimension, and extensive considerations of four-dimensional space's simpler properties.
Since each essay is independently conceived, all of the writers offer fresh viewpoints and original examples. Because of this, some of the most important principles relating to the fourth dimension are viewed from several different angles at once -- an invaluable aid to visualizing these abstruse but fascinating ideas. New Introduction by Thomas F. Banchoff, Brown University. 82 figures.

Like a new bed.
Color: White, Size: Queen
Surprising how small the box it was delivered in. As the packaging is removed, the topper grows to full size. Easy to install. Very comfortable to sleep in. Getting into and out of a bed that is four inches taller takes some getting used to.

Overall decent
Color: White, Size: King
It smelled a bit “chemically” for the first few days. The smell did fade and eventually go away entirely. It also still slides off of my bed despite having the straps to hold it in place. Otherwise, I have no complaints. It’s extremely comfortable and adds a few extra inches to the height of my bed.
