What's in a Name, Rubik's Cube

When Hungarian professor Ernő Rubik invented the Rubik's Cube in 1974 to teach his students about 3-D geometry, even he could not solve the puzzle he had created.

He famously wrote that it was like, "staring at a piece of writing written in a secret code, but for me, it was a code I myself had invented! Yet, I could not read it. This was such an extraordinary situation that I simply could not accept it." He eventually learned to master the cube and could solve the puzzle in under a minute.


Incidentally, Yusheng Du, beat the previous world record of 4.22 seconds with the jaw-dropping time of 3.47 seconds earlier this year.
