Geometrical Researches On The Theory Of Parallels is a book written by Nicholas Lobachevski, a Russian mathematician, in 1840. The book presents Lobachevski's groundbreaking work on non-Euclidean geometry and his theory of parallels. Lobachevski challenges Euclid's fifth postulate, which states that through a point not on a line, there is only one line parallel to the original line. Lobachevski demonstrates that there can be multiple parallel lines through a point not on the original line, leading to a new type of geometry. The book includes numerous geometric proofs and illustrations to support Lobachevski's arguments. Geometrical Researches On The Theory Of Parallels is considered a seminal work in the history of mathematics and a significant contribution to the development of non-Euclidean geometry.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
