Part 2/6:
The world of Rubik's Cube-solving machines is not just about speed but also the technical specifics involved in making such rapid solves possible. With the students at Purdue, speed is achieved through meticulous engineering and mechanical design. Interestingly, their machine can solve the cube faster than the human blink, which occurs at around 200 to 300 milliseconds. Even more remarkably, it outpaces the average human reaction time of 100 to 200 milliseconds, resolving the puzzle seemingly before one has even processed the change.
