その理由の多くは、スクランブルをかける方法が文字通り何十億通りもあるという事実と関係があります。

キューブを解くのが速い人の特徴は、おそらく3つあると思うんです。

キューブ技術が向上したことで、先ほどお見せしたような経済的な動きにも変化が生じているようです。

というのも、緊張しているときに早く曲がろうとすると、とてもうまく曲がれないんです。

解き方を批評してもらったが、本当に失敗しそうだ。
Ready?
準備はいい?
Ohnodamnthat's a slow 11 minute 41 seconds I'm ashamed.
いやーくそー11分41秒は遅いなー恥ずかしいなー。

地球上で最も速いスピードキューブは、1秒間に平均10回転していることを思い出してください。

実はこのロボット、1秒以内に解くことができるんです。
Sofrom a purelymathematicalstandpoint, a sub 2 2ndsolveby a humanshouldbepossible.
ですから、純粋に数学的な観点から言えば、人間による2秒以下の解答は可能なはずです。
