魔方的基本术语
阶:阶数是指魔方每个边所具有的块数,比如三阶魔方每个边就有3个小块。
复原:指魔方从非原始状态到原始状态的过程。
POP:俗称飞棱,指在复原中魔方的某些组成部分从魔方上面脱离的情况。
DNF:即Did Not Finished,指魔方复原者感觉无法在自己满意的时间内完成魔方而弃权的情况。

魔方的起源

正如本条目开头所言,最早的魔方是鲁比克教授发明的,但是并不是为了投入生产和娱乐。因为他是建筑学和雕塑学教授,所以
他自己动手做出了第一个魔方的雏形来帮助学生们认识空间立方体的组成和结构。在他完成第一个作品以后,转动了几下,发现原本
齐整的魔方竟然很难恢复,于是他意识到这这个新的发明会很不简单。但是他想不到的是,这个边长不到6厘米的玩具竟然会在未来
全球,甚至出现了以魔方为道具的运动

魔方的基本概念

我们常见的魔方是3x3x3的三阶魔方,是一个正6面体,有6种颜色,由26块组成,有8个角块;12个棱块;6个中心块(和中心轴支
架相连)。
为了便于描述魔方复原过程,我们需要熟悉魔方的一些基本概念——面、层、角块、棱块、中心块,面位、到位、归位。
面是指一个平面的3 x 3块,层是指一个平面3 x 3块所处3 x 3 x 1块,请仔细比较一面和一层的区别,我们旋转的是一层,复
原的是六面。
