索瑪立方塊(Soma Cube)
I. 索瑪誕生的故事
1969夏，派克兄弟公司(Parker Brothers Inc.)首度將索瑪立方塊上市。在此之前，馬丁‧嘉德納(Martin Gardner)曾撰文在《科學美國人(Scientific American)》的數學遊戲專欄中介紹過，並使它風靡全球。索瑪立方塊可以用來協助人們增進空間關係的思維技能，它能讓人們沈迷數小時享受探索的樂趣。
索瑪立方塊是由丹麥亞特‧海恩(Piet Hein)發明的。1936年，皮亞特‧海恩在聆聽偉納‧海森伯格演講“量子物理”的場合，構思出索瑪立方塊的。當時這位德國物理學家正在講述把空間切割成立方體。皮亞特‧海恩敏銳的想像捕捉到以下的幾何原理：
將四個以內，大小相同的立方體，以面相連接，構成的所有不規則形狀，可以重組成一個較大的立方體。
海森伯格還在演講，海恩已經很快地在紙上塗塗畫畫，確定這總體積為27個單位的七片形狀可以組成一個3x3x3的立方體。演講結束後，他把27個立方體黏成這七個形狀，並很快地證實他的想法。索瑪立方塊從此誕生。
