With a voluminous literature going back some 2,500 years, the universal assumption has ever been that magic squares are inherently arithmetical objects. In this innovative work by a British engineer, the author initiates a Copernican revolution in our understanding by replacing numbers with two-dimensional forms. The result is not merely a novel kind of geometrical magic square but a revelation that traditional magic squares are now better seen as the one-dimensional instance of this self-same geometrical activity.\u003c\/p\u003e","brand":"Book Outpost","offers":[{"title":"Default Title","offer_id":48378755317981,"sku":"9780486489094","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/9867\/8237\/files\/9780486489094.jpg?v=1786828308","url":"https:\/\/handfulofbooks.com\/products\/geometric-magic-squares-a-challenging-new-twist-using-colored-shapes-instead-of-numbers-dover-puzzle-books-math-puzzles","provider":"Handful of Books","version":"1.0","type":"link"}
