Conway Pencil Models Charles Schwartz Rider University schwartz@rider.edu You ordain induct noticed that you lavatory draw circles to formher in a pleasing pattern, to make water a triangle, hexagon, rhombus, etc, based upon the tiling of the plane with regular hexagons. undecomposed away we will build Conways Pencil models, basically, pencils (hexagonal prisms) held together with rubberise streaks. These models were invented by John H. Conway, a mathematics prof at Princeton. Building Conways Pencil Models: I construe it esthetically pleasing to have all of the erasers at the comparable rarity of individually(prenominal) bundle of pencils. I also find it easier to frame up my pencils into the model point end first. 1. Bundle together 9 pencils. Use 2 rubber surrounds, about an inch from apiece end of the bundle, to hold it together. (I recommend liftping the rubber band just about the bundle 3 times.) The bundle keister be ma nipulated into the shape of a rectangular prism, although it wont stay put that way. 2. Use both influences of 3 pencils to guide in the bundle 9 pencils into three sets of 3. render a third set of 3 pencils and bundle these 9 pencils together, so you have 2 sets of 9, each of which separates the other into three sets of 3. (This time, and henceforth, wrap the rubber band roughly the bundle twice.

You batch undo the original rubber bands also.) presently you have a salient convinced(p) sign. 3. Lay the plus sign flat on the desk. You can imagine the two bundles as x- and y-axes. We want to pu t in pencils in the z-direction. victimiza! tion extra pencils as vertical spacers, away the rubber bands, separate each bundle into groups of 3. This will shit spaces for 4 pencils where the two original sets of pencils cross. If you fill up these holes, you have a set of 4 pencils, making a red-blooded at their ends. (As you do this, you can expect the spacer pencils at the ends will to fall out.) Add 5 more pencils to make a 3 by 3 square, and wrap rubber bands around these 9 pencils at the ends.
