Do You Hate It or Love It?
If you can complete the Rubik's cube then you love it, but if
you can't then you hate that piece of plastic with 26 parts and
one frame.
For 18 years I fiddled and got frustrated by the cube. When you
are young there is lots of time to spend on this sort of thing.
At the age of 21 someone showed me the moves required to solve
the cube. I was very pleased but also highly annoyed that it
took 18 years for me to find the solution.
I am now 26 and I have done some research on that rigid time
waster some people call a puzzle. It is way more than a puzzle!
Many people have studied the maths of the cube, hence the
algorithms available on some sites that will solve any cube so
long as you enter the colors in correctly.
The maths used in the cube is of a higher form that is studied
at school, it is called group theory. Enough of that though!
There are two ways to do the cube. The short way, and the long
way.
The long way involves completing one side first and then
completing the rest of the cube, using sequences of moves that
move certain blocks around. There are a few different methods
and they all require you to remember sequences of moves for
different situations.
Each person is different and one person might prefer one method
over another, but for me the main criteria for a solution is the
ease with which the solution can be remembered, so that a couple
of months down the line you will still be able to do the cube
without having practiced.
The short way involves hours of dedication and a good memory.
Sequences of turns are memorized along with what the sequence
achieves. The difference here is there are over 40 different
sets of moves, and even more depending how determined you are.
To complete the cube in the world record time of 16.5 seconds
(averaged over 3 attempts, in front of an audience) requires you
to know just the right turns to get the mixed up cube to the
completed state. I would imagine that a person would have to
almost become
