{"product_id":"penrose-ladder-midnight-blue","title":"Penrose Ladder — Midnight Blue","description":"In 1958, mathematician Lionel Penrose and his son Roger — who would later win the Nobel Prize in Physics for his work on black holes — published a paper describing a staircase that went up forever and arrived back where it started.\n\nIt was geometrically impossible. Each individual section looked correct. The connections between them created a loop with no exit.\n\nWhen Roger Penrose had first seen M.C. Escher's impossible figures a few years earlier, he had been completely captivated. He and his father sent a copy of their paper to Escher. Escher wrote back. He had just made a lithograph inspired by the staircase — Ascending and Descending, 1960 — monks walking endlessly up and endlessly down, going nowhere forever.\n\nWhat the Penroses formalized and what Escher made visible was the same idea: that the rules that govern individual parts of a system can produce, collectively, something that cannot exist.","brand":"White Nights","offers":[{"title":"Midnight Blue \/ S","offer_id":49784848482531,"sku":"WHITENIGHTS_PLMB38217_RNHS-MB-S","price":799.0,"currency_code":"INR","in_stock":true},{"title":"Midnight Blue \/ M","offer_id":49784848515299,"sku":"WHITENIGHTS_PLMB38217_RNHS-MB-M","price":799.0,"currency_code":"INR","in_stock":true},{"title":"Midnight Blue \/ L","offer_id":49784848548067,"sku":"WHITENIGHTS_PLMB38217_RNHS-MB-L","price":799.0,"currency_code":"INR","in_stock":true},{"title":"Midnight Blue \/ XL","offer_id":49784848580835,"sku":"WHITENIGHTS_PLMB38217_RNHS-MB-XL","price":799.0,"currency_code":"INR","in_stock":true},{"title":"Midnight Blue \/ XXL","offer_id":49784848613603,"sku":"WHITENIGHTS_PLMB38217_RNHS-MB-XXL","price":799.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/9062\/7299\/files\/017892310066aa57f9e990397wn-penrose-ladder-midnight-blue_mockup.png?v=1789992412","url":"https:\/\/whitenights.store\/products\/penrose-ladder-midnight-blue","provider":"White Nights","version":"1.0","type":"link"}
