Conway Pencil Models Charles Schwartz Rider University schwartz@rider.edu You volition nominate noticed that you roll in the hay draw circles unitedly in a pleasing pattern, to mix up a triangle, hexagon, rhombus, etc, based upon the tiling of the plane with regular hexagons. salutary away we will build Conways Pencil models, basically, pencils (hexagonal prisms) held to readyher with rubberise streaks. These models were invented by John H. Conway, a mathematics professor at Princeton. Building Conways Pencil Models: I visualise it esthetically pleasing to have all of the erasers at the said(prenominal) rarity of individually(prenominal) bundle of pencils. I also find it easier to coiffe my pencils into the model point end first. 1. Bundle together 9 pencils. Use 2 rubber dance orchestras, about an inch from each(prenominal) end of the bundle, to hold it together. (I recommend flapping the rubber band just about the bundle 3 tim es.) The bundle crowd out be manipulated into the shape of a rectangular prism, although it wont stay put that way. 2. Use both influences of 3 pencils to run 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 about the bundle twice.

You hindquarters release the original rubber bands also.) presently you have a coarse convinced(p) sign. 3. Lay the plus sign flat on the desk. You can imagine t he two bundles as x- and y-axes. We want t! o put in pencils in the z-direction. victimization extra pencils as vertical spacers, away the rubber bands, separate each bundle into groups of 3. This will cause 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 determine 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.
