The Rubik's Cube
Finding Balance
I proceeded to do some research on how solving the Rubik’s Cube has impact people’s lives and I came across this fascinating gem: http://www. bertmeert. com/blog/life-lessons-from-the-rubiks-cube/. Bert Meert comments on the various stages of the cube and how it correlates to life lessons. He continues to question how we view things in the world and how our decisions impact our lives. It’s an interesting read for sure, and I recommend it to everyone. Although it isn’t about how to solve the cube, it definitely connects the process of learning and solving the Rubik’s Cube to our daily world and how we experience various instances.
Methods of Solving Part 3: Petrus
It’s time for another method of solving! Hooray! Alright, so the premise behind the Petrus method is intuition. The entire method relies of user cognitive strategies rather than memorization of algorithms. Patterns and fast reflexes are everything in this method.
The steps include building a 2x2x2 corner, then expanding it to 2x2x3, and then finally finishing off the last layer using a few tricks. The entire tutorial written by Lars Petrus, the founder, himself can be found here: http://lar5.com/cube/. It definitely won him some great honors and is definitely user friendly for people who just lack memorization skills or don’t want to spend that time.
Rubik’s Cube World Championships
Http://www. speedcubing. com/ is an interesting website that highlights all of the world records and championship events in Rubik’s Cubing since last year. Although it hasn’t been updated in almost a year, it still has great information. It has a section with rankings for each variation of the cube as well as the results from the 2011 World Championship event that was held in Bangkok. It’s interesting to observe the times that was achieved in each section and what a huge discrepancy there is between some individuals. I guess it shows that some are truly on another plane than others.
So I’ve just started to cube again after taking a brief hiatus. It’s been interesting trying to reach my old times again. One thing that helps me for sure is to watch professionals solve the cubes and see how they use their hands as well as stay calm under the pressure of beating the clock. Jessica Fridrich is one of the fastest solvers of the cube and this following video is quite entertaining to watch to see her quick hands solve the cube in a blistering speed.
The Rubik’s Cube is a puzzle that is visually stimulating. I, for one, have always been intrigued at the numerous amount of patterns that can be created using the Rubik’s cube. There are many symmetrical patterns that require simple maneuvers of opposite edges, as well as other more complex patterns that really bewilder a pedestrian crowd. I’m planning on learning a few impressive ones to show the class during my presentation.
Http://www. randelshofer. ch/rubik/pocket/A200.01.html actually has many many patterns to choose from as well as an animation to show the viewer how to make them. They actually have patterns for every standard variety of the Rubik’s cube (2×2, 3×3, 4×4, etc.). There are some such as the “labyrinth” that I never would have thought of. Check it out, its an interesting page.
Manufacturing
The manufacturing of a Rubik’s Cube is a topic that piqued my curiousity. I wondered just how these 3×3 cubes were mass manufactured and shipped. I ran into this website: http://www. madehow. com/Volume-7/Rubik-s-Cube. html#b, which explains this process in detail.
The raw materials used to make a cube are made from plastics, many being thermoplastics. They are light, rigid, and can be molded into various forms, so they are essential in creating the cubes. There are 4 essential steps in the production of the Rubik’s cube. They are:
- Molding – an injection molding machine uses a combination of heat and pressure to mold the various plastics into the desired shapes that the cube require. Once finished, they are inspected in a bin to make sure no damage had taken place. Parts Assembly – the pieces are placed on an assembly line where they are built from the bottom up into a cube. Labeling – the cubes are then labeled with a sheet polypropylene material. This material is colored and then applied to the cube. (These are the stickers that you see.) Packaging – The cubes are then packaged into small boxes, usually with an instruction manual and then put on trucks and shipped around the world.
Quality control is a procedure that takes place throughout the entire manufacturing process. Quality control inspectors check the product at each phase of the process to ensure that the highest quality is achieved.
I was curious as to how many designs of puzzles there actually are based on the Rubik’s Cube. It turns out that there are quite a few. I did a simple search on Amazon of “Rubik’s” and many many results popped up.
This is a standard 3×3 cube.
This is a 2×2 cube. These are pretty popular because of the low skill level needed.
This is a 4×4 cube. They are tricky because they involve cases of “parity” which have a couple of long algorithms associated with them.
This is a 5×5 cube. Quite similar to a 4×4 in terms of difficulty and popularity.
These 7×7 cubes are quite rare and come with a hefty price tag. My mentor, Mr. Mickel, owns one and is quite proficient at solving it.
Now these are the more “out there” designs:
These are all based around the initial design of a 3×3 Rubik’s Cube. They each have their own algorithms and tricks to solve them. It’s interesting how a simple 3×3 cube of colors can lead to to the development of all of these trinkets.
Rubik's Cube Solver - Solution Page
You are on the solution page, generated by the online Rubik's Cube solver.
Allow some time for the program to calculate and return the solution. This usually takes around 20 seconds but it can go up to 2 minutes so please be patient. This solver won't find the same steps that you applied for the scramble but depending on your computer's performance it finds the solution in 20-25 steps.
How To Apply The Solution?
Hold the cube in your hands as the program shows the starting position. This is the same orientation you used when you input the colors.
If you know what the letters mean in the solution (explained below) you can easily apply the steps. Alternatively you can click through them one by one or play the solution with the desired speed, while you're following the turns.
You can find images of all steps from the starting position to the solved state. The images have marked faces showing which has to be turned in which direction. Watch out for double 180° rotation which are marked with 2x.
Be careful because if you miss or fail one move you end up with a scrambled cube and you'll have to start it over!
How Does It Find The Solution?
The program is using the algorithm of Herbert Kociemba's Cube Explorer (open-source program from kociemba. org). This method is able to find the solution for any initial scramble in 20 half-turn metric steps (180° rotatoins count as one step), however we had to limit this solver to protect our server.
First it's looking for the solution in 20 steps (God's Number) but if the program doesn't return any result below the time threshold then it's switching to 24 steps and returns the nearly optimal solution.
Impossible Scramble Error Message
If you get this warning then go back to the scramble page and make sure you entered the colors correctly. If the program keeps returning this error message then your cube might have been taken apart and put back together in an unsolvable configuration. There's only a 8,3% chance that your cube will be solvable if you take it apart and rebuild it in a randomly scrambled position.
The solution is simple. You have to take your cube apart and rebuild the pieces in the solved position.
What Do The Letters Mean In The Solution?
The rotations of the six sides of the puzzle are marked with letters:
F - Front, R - Right, U - Up, D - Down, L - Left, B - Back
Each letter means a ninety-degree clockwise rotation of the marked side. Counterclockwise turns are marked with an apostrophe, while double-turns are marked with the number 2. Activate the Animate rotations option to see these explained during the playback.
