How to solve a Rubik's Cube within 5 seconds
The Rubik's Cube was invented in 1974 by Hungarian professor Erno Rubik. While originally intended as a tool to help explain 3D geometry to his students, it has become one of the best-selling toys of all time. Multiple competitions are held around the world every year, where people try to solve the cube as fast as possible. As of September 2, the world record is 4.69 seconds. In this talk, I will go over the history of the cube and show some of its many spin-offs. There are also several interesting things one can do with the cube. But how does one actually solve it? There are multiple solving methods, of which I will explain one that is very similar to the method used by most speedcubers. Have a cube lying around that has been gathering dust somewhere in a drawer for years? Bring it and it will leave the room in a solved state!
