Flatland [EPUB ebook] 

The book that influenced writers from Carl Sagan to Stephen Hawking, Flatland is set in a two-dimensional world where life exists only in lines and shapes – until one of its inhabitants, ’A. Square’, has his perspective transformed forever. This brilliantly eccentric classic is an invitation to see beyond our own reality.’At once a playful brainteaser about geometry, a pointed satire of Victorian manners – and a strangely compelling argument about the greatest mysteries of the Universe’ Wall Street Journal’Flatland could lead to very profound thought about our Universe and ourselves’ Isaac Asimov
