Line by line in this classic work he carefully presents a new and revolutionary theory of parallels, one that allows for all of Euclid s axioms, except for the last. This 1891 translation includes a bibliography and translator George B. Halsted s essay on elliptic geometry. Russian mathematician NICHOLAS LOBACHEVSKY (1792 1856) is best remembered as the founder (along with Janos Bolyai) of non-Euclidean geometry. He is also the author of New Foundations of Geometry (1835 1838) and Pangeometry (1855).\"\u003c\/p\u003e","brand":"Cosimo Classics","offers":[{"title":"Paperback","offer_id":45608107147415,"sku":"9781602064676","price":1541.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781602064676.webp?v=1767465945","url":"https:\/\/atlanticbooks.com\/products\/geometrical-researches-on-the-theory-of-parallels-9781602064676","provider":"Atlantic Books","version":"1.0","type":"link"}
