Book DetailsSpectrumVolume: 69; 2011; 227 ppRecipient of the Mathematical Association of America's Beckenbach Book Prize in 2015!
Lobachevski Illuminated provides an historical introduction to nonEuclidean geometry. Within its pages, readers will be guided stepbystep through a new translation of Lobachevski's groundbreaking book, The Theory of Parallels.
Extensive commentary situates Lobachevski's work in its mathematical, historical, and philosophical context, thus granting readers a vision of the mysterious and beautiful world of nonEuclidean geometry as seen through the eyes of one of its discoverers. Although Lobachevski's 170yearold text is challenging to read on its own, Seth Braver's carefully arranged “illuminations” render this classic accessible to any modern reader (student, professional, or layman) undaunted by high school mathematics.

Reviews

Seth Braver doesn't just interpret the existing contents of Lobachevski's Theory of Parallels, but he continually adds to it by way of making it more mathematically coherent. In this respect, his achievement is first rate and it is equalled by his eloquently inspiring literary style. … As such, this is a masterly addition to the literature on the history of geometry.
