How to solve the rubik cube

 This has been such a fascinating journey.

When I told my friend about this recent solve the rubik project, she said that I was keeping my brain sharp. I can see how you can pick up a rubik cube and solve one piece and go back to what you were doing just like a huge jig saw puzzle which you know will involve many retreats and advances.

Each interaction with it, I am learning something new.

I have come to the third layer, making a plus. I know that from here, it is an algo again, which I can learn like Emily. But I want to solve it the math way, where you flip one edge of a done face and then do the reverse. So today I was working on flipping an edge but of an unmade face. When I tried that on a done face, it fell flat. But what I have learnt is how easy all the othe rthings have become, especially making the face and even in that, removing pieces that I dont need and also recognizing part done algos especially the fixing corners of a face. One more step away in figuring that elusive way of flipping that edge of a made face.

I asked a rubik cube owner for some tips and he suggested trying a face first. When I asked him if he knew of the flipping an edge piece method - he said that you just have to try it out.

This gets better and better. What mathematician Burkard Polster was trying to teach was a simple trick to design your own solution to rubik's cube. This is by decomposition of the complex problem into set of 4 moves of flipping edges and corners and moving edges and corners, which can then be translated to any kind of similar puzzle.

I now know how to flip edges. I am moving edges now. Yesterday after flipping an edge and realising that a twist is needed and found that two edges would be flipped. Now I understand the commutator the professor was referring to.

Moving edges is easy to understand through this move of the corner piece in between as going up.

Dora The Explorer Puzzle Cube Favor for Parties and Celebrations

 

Dora The Explorer Puzzle Cube Favor for Parties and Celebrations, 1-1/8 x 1-1/8 x 1-1/8", Multicolored


Tried to figure this rubik;s cube with the following video. I was able to get the plus or the cross sign, but after that since there are more complications in this picture, I couldnt follow the instructions as is from the classic one which has only colors. The other rubic cube we have is a Sudoku cube.

If you have patience to do one layer, here's a trick. Using maths to solve the rubik cube, at 17:36 in the TED talk, you can see how you can switch one edge piece and reverse those steps to put it all in order. The mathemagician says that at the most you need 20 moves to solve a rubik cube.
I loved the explanation in this video, especially the maneuvering with the reasoning behind it, instead of just algorithm of what to do.

Robin Coste Lewis




Robin Coste Lewis is a great poet. Read the Pen Ten with Robert Coste Lewis. I enjoyed reading On the Road to Sri Bhuvaneshwari as it was a common ground. The center big piece 'Voyage of the sable Venus' is an experiment in terms of the arrangement of the content from the titles of museum exhibits, but so is every poem. In one when poem, where every scene is in the 'not' frame, I knew something dreaded was coming.
In Verga, a jumbled pantoum, a reverse rubik cube where any move from the horror is only weirder.
Every word of her seems well strained. Most likely poems to be sent to moon, as they represent humanity.

Rubiks cube Art

My friend sent this link to  Rubiks cube art
Most people usually have one or no Rubik's cube in their house.
A pattern on one cube would have set off the artist to gather more and coming to the realisation that the artist would need so many Rubiks cube is a crazy Eureka moment. Making icon pictures out of icon material is a hedged tete-a-tete with audience (for lack of a specific term for art readers).
