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 \u003c\/span\u003e\u003cspan class=\"a-text-italic\"\u003egeometrical\u003c\/span\u003e\u003cspan\u003e activity.\u003cbr\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"refreshable_ppd-center_21\" class=\"celwidget\" data-feature-name=\"refreshable_ppd-center_21\" data-csa-c-type=\"widget\" data-csa-c-content-id=\"refreshable_ppd-center_21\" data-csa-c-slot-id=\"refreshable_ppd-center_21\" data-csa-c-asin=\"0486489094\" data-csa-c-is-in-initial-active-row=\"false\" data-cel-widget=\"refreshable_ppd-center_21\" data-csa-c-id=\"eszcyv-l959xt-lcwovr-jbf4fz\"\u003e\n\u003cdiv id=\"globalStoreInfoBullets_feature_div\" class=\"celwidget\" data-feature-name=\"globalStoreInfoBullets_Books\" data-csa-c-type=\"widget\" data-csa-c-content-id=\"globalStoreInfoBullets_Books\" data-csa-c-slot-id=\"globalStoreInfoBullets_feature_div\" data-csa-c-asin=\"0486489094\" data-csa-c-is-in-initial-active-row=\"false\" data-cel-widget=\"globalStoreInfoBullets_feature_div\" data-csa-c-id=\"vtf79-6d4p3u-w6di34-fmp8ch\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"buyingOptionNostosBadge_feature_div\" class=\"celwidget\" data-feature-name=\"buyingOptionNostosBadge_Books\" data-csa-c-type=\"widget\" data-csa-c-content-id=\"buyingOptionNostosBadge_Books\" data-csa-c-slot-id=\"buyingOptionNostosBadge_feature_div\" data-csa-c-asin=\"0486489094\" data-csa-c-is-in-initial-active-row=\"false\" data-cel-widget=\"buyingOptionNostosBadge_feature_div\" data-csa-c-id=\"iuovah-kxd02k-kyv3ee-mokxi0\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"tellAmazon_feature_div\" class=\"celwidget\" data-feature-name=\"tellAmazon\" data-csa-c-type=\"widget\" data-csa-c-content-id=\"tellAmazon\" data-csa-c-slot-id=\"tellAmazon_feature_div\" data-csa-c-asin=\"0486489094\" data-csa-c-is-in-initial-active-row=\"false\" data-cel-widget=\"tellAmazon_feature_div\" data-csa-c-id=\"nnrh61-7qa60r-3uhwb6-aude26\"\u003e\n\u003cdiv class=\"celwidget c-f\" data-csa-op-log-render=\"\" data-csa-c-content-id=\"DsUnknown\" data-csa-c-slot-id=\"DsUnknown-11\" data-csa-c-type=\"widget\" data-csa-c-painter=\"tell-amazon-desktop-cards\" data-cel-widget=\"tell-amazon-desktop_DetailPage_10\" data-csa-c-id=\"m1lf6m-44t3g2-43yh0l-od5y43\"\u003e\n\u003cdiv id=\"CardInstanceE5coE_tu7qBBz9fonCzBkw\" data-card-metrics-id=\"tell-amazon-desktop_DetailPage_10\" data-acp-tracking=\"{}\" data-mix-claimed=\"true\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sallows, Lee C.
