It is hard to solve a Rubic´s Cube.
It is even harder to solve a Rubik´s Cube in the mind.
I was inspired by this idea, when I saw several Rubik fanatics,
who solved the Rubik´s Cube blindly. It is amazing to watch,
how they inspect the Rubik´s Cube and then close their eyes.
... and after some turns the cube is solved. Wow!!
My ambition was spurred. Can I also solve a cube blindly?
I could not give up this idea. After several weeks
I started to make my first experiences.
I found out that there are two possibilities.
You can either memorize the stickers on the cube
or all the moves which you have to make.
I chose to memorize the stickers on the cube.
I recognized very fast that this plan would take around one year.
There are a lot of cognitive skills to learn, before you can do that.
I began with the 1 * 1 * 1 cube. My first exercise was to turn the cube only several times.
After two weeks, I had the feeling that I really saw the cube and his six colors.
It is amazing to have this feeling. I also memorized the orientation of the six colors mentally.
So I still remember how the cube, which I have turned in my mind several weeks ago, looked like.
Now I am practicing with the 2 * 1 * 1 cube.
