Lieber, Lillian R. Hugh Gray Lieber (drawings)
Non-Euclidean Geometry or Three Moons in Mathesis
|
|
Lancaster, PA: The Science Press Printing Company, 1940. Second Edition (first published in 1931). With the Liebers blindstamp at the lower corner of the title page. Thin red comb binding, black wrappers with titles and designs in silver, and geometric figures in silver on the endpapers.
Written in free verse, the Liebers have managed to simplify non-Euclidean geometry, and have helped many generations understand mathematics through their teaching methods. Cute illustrations in black-and-white throughout.
Near Fine with light yapping to the wrappers at the top and bottom edges, and very faint scattered foxing to the page edges. An attractive copy. [Book #119565]
