1. 狂顶这一句:
“我一直是喜欢研究魔方的结构,三阶魔方是鲁比克1975年发明的,经历了20多年后,现在国内外出现一些适合速拧的三阶魔方并没有脱离老鲁设计的三阶结构框架,大都是细节上改进下使魔方更适合玩速拧。”
但有些资料显示鲁比克发明魔方是1974年啊,申请专利是1975年...维基百科中是这样写的:
“In the mid-1970s, Ernő Rubik worked at the Department of Interior Design at the Academy of Applied Arts and Crafts in Budapest.[10] He sought to find a teaching tool to help his students understand 3D objects. Rubik invented his "Magic Cube" in 1974 and obtained Hungarian patent HU170062 for the Magic Cube in 1975 but did not take out international patents. ”
