Rubicks Cube
How to Logically Solve a Rubik’s Cube Kenneth Cason First, as with any problem, it is important to understand what your objective is. In the case of the Rubik’s Cube, the main goal is to arrange the pieces in such a way that each side is the same color. Next lets luck at the structure of a standard 3x3 Rubik’s Cube. It is a cube composed of 6 sides, each side composed of 9 stickers (3x3). There are 8 corner pieces, 12 edge pieces and 6 center pieces (one on each side). It is also important to note that on all “odd” Rubik’s Cube’s the center pieces can rotate clockwise or counter clockwise, but the positions are fixed. “odd” meaning that the cube is a 3x3, 5x5, NxN, where N is an odd number. Also, because the center pieces are fixed it becomes immediately obvious which side is which color. Now that we know the basic structure of a Rubik’s Cube next lets think about strategies to solve it. First, lets examine what is probably the most common way to solve a Rubik’s Cube, the “Layer by Layer” method. For those not familiar with the Layer by Layer method, it involves solving the top, middle, and bottom layer in that order. However, despite this seeming to be the most logical way to approach the Rubik’s Cube, it is actually farm more difficult to solve in this manner. The problem is very simple. If you solve the first layer completely, in order to solve the second layer without messing up the solved first layer the moves grow in length and complexity. Then to solve the bottom layer without messing up the top and middle ayers, the moves again grow even more complex. To add a quantitative example, lets look at the case of trying to place a piece in the second row without messing up the first row it takes 7 permutations, and to switch the bottom layer edge pieces positions without messing up the top and middle layers, permutations can be as much as 15, in which you are more likely to give up before you ever derive on your own techniques. Not to say that it is

    First we picked our task as feed the money pig, and decided on our group name as Oink! Oink! Then we brainstormed our ideas and wrote them down. We then wrote our detailed description of our steps from start to finish. Then we completed our materials list to know the materials we got from the teacher and the materials that we would have to bring in. We also completed a list of dates of our project completion goals and testing. Next we began building our Rube Goldberg project. We all bought in the materials we needed for our project along with the ones we got from our teacher. For our first step we set up a small table up on a larger one. Then we taped a Twix box with marble at the top to the small table; we then taped a toilet paper roll to it and used it as a inclined plane. We set ten dominios under it on the table and put a marble at the end of them for our next step. In next step we taped a funnel at the end of the table and set up a mousetrap under the funnel. In our next step we tied a string to the mousetrap and tied the other end to a popsicle stick. We then put the stick on a toilet paper roll, that we used as an inclined plane, and put a golf ball and two marbles at the top of the stick. In our next step we set up another smaller table with two books on it, which were used as tracks for two balls that hit each other. Then we set up playing cards and Jenga blocks to make a track for the ball that falls off the table in our next step. Then in our next step we tied a Jenga block to beads that fall off the larger table. Next we set up a Coke can on a piece of wood used as an inclined plane. We then tied popsicle sticks to the beads and put them under the Coke can for our next step. In our next step we put a piece of wood at the bottom of the inclined plane with the Coke can on it. Then we tied a string to the piece of wood and tied the other end to…

Ball pythons are active around dawn and dusk. The typically grow between four and five feet in length. Ball pythons are known for curling up tightly and burrowing.

    Sensory play and sensory devices have been around for a while now, and have been manufactured in order to help create a sensory input to calm and focus children with ADHD, ADD, or autism. Furthermore, are fidget spinners productive or are they just a distraction. Now, I tend to fidget a lot, I press my fingers against my palms, twiddle my thumbs, and sometimes, have a hard time focusing. This is only when i’ve been sitting a desk for a while, and I constantly feel the need to be doing something productive, or I feel like i’m wasting my time. The science behind fidgeting actually isn’t very complex. Said by Roland Rotz, “If something we are engaged in is not interesting enough to sustain our focus, the additional sensory-motor input that is mildly stimulating, interesting, or entertaining allows our brains to become fully engaged and allows us to sustain focus on the primary activity in which we are participating.” For example, If you are fully engaged in watching a baseball game in the bottom of the 9th, I’ll bet you're not fidgeting a lot because you're focused…

Tree-ear, the main character, is a parentless, 12-year-old child who was raised under a bridge by a kind man with a crippled leg who went by the name of Crane-man. Despite this obviously poor life Tree-ear lived, he had one day that he looked forward to that he called, “throwing day” a day when a very skilled potter named Min spun a beautiful clay vase to Tree-ear’s enjoyment. One throwing day Tree-ear was caught watching Min’s work when he thought that Min was not around, and accidently dent the uncooked piece of clay after dropping it from surprise. Min, who was very angry at this, punished Tree-ear by making…
