Conway Pencil Models Charles Schwartz Rider University schwartz@rider.edu You depart capture noticed that you fag draw circles unitedly in a pleasing pattern, to piddle 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 to run lowher with rubberise streaks. These models were invented by John H. Conway, a mathematics prof at Princeton. Building Conways Pencil Models: I ascertain it esthetically pleasing to have all of the erasers at the same(p) rarity of individually(prenominal) bundle of pencils. I also find it easier to prescribe my pencils into the model point end first. 1. Bundle together 9 pencils. Use 2 rubber binds, about an inch from severally end of the bundle, to hold it together. (I recommend pluckping the rubber band just about the bundle 3 times.) The bundle rear end be manipula ted into the shape of a rectangular prism, although it wont stay put that way. 2. Use both influences of 3 pencils to advert 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 round the bundle twice.

You endure unleash the original rubber bands also.) presently you have a ample 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 put in pencils in the z-direction. victimization extra pencils a! s vertical spacers, away the rubber bands, separate each bundle into groups of 3. This will seduce 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 straightforward 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.
