Non-Euclidean Geometry (Mathematical Association of America Textbooks)
'No living geometer writes more clearly and beautifully about difficult topics than world famous Professor H. S. M. Coxeter. When non-Euclidean geometry was first developed, it seemed little more than a curiosity with no relevance to the real world. Then to everyone's amazement, it turned out to be essential to Einstein's general theory of relativity! Coxeter's book has remained out of print for too long. Hats off to the MAA for making this classic available once more.' Martin Gardner'Coxeter's geometry books are a treasure that should not be lost. I am delighted to see Non-Euclidean Geometry back in print.' Doris Schattschneider
