Synopsis:

This book encompasses a wide range of topics in the wild realm of geometry, from as basic concept as ‘point’ to as state-of-the-art discipline as ‘topology’. It is aimed at readers with a minimum background of junior school mathematics. Despite vivid and technical descriptions of various mathematical oddities, the book never loses its focus, which is to keep the attention of the reader as if they are reading a suspense thriller and not a book on hard-cold mathematics. This is not only the first book by Saumitra Chakravarty, but also the first original book of its kind ever written in Bengali. This is one of the popular science bestsellers in Bangladesh and enlisted by Bangladesh Math Olympiad Committee as a per-requisite text of preparatory classes for competitive math exams.
