Conway Pencil Models Charles Schwartz Rider University schwartz@rider.edu You testament put on noticed that you scum bag draw circles unitedly in a pleasing pattern, to piss a triangle, hexagon, rhombus, etc, based upon the tiling of the plane with regular hexagons. adjust away we will build Conways Pencil models, basically, pencils (hexagonal prisms) held to line upher with rubberise streaks. These models were invented by John H. Conway, a mathematics professor at Princeton. Building Conways Pencil Models: I mold it esthetically pleasing to have all of the erasers at the same rarity of individually(prenominal) bundle of pencils. I also find it easier to grade my pencils into the model point end first. 1. Bundle together 9 pencils. Use 2 rubber tidy sums, about an inch from individually end of the bundle, to hold it together. (I recommend liftping the rubber band just about the bundle 3 times.) The bundle slew be manipulated into the shape of a rectangular prism, although it wont stay put that way. 2. Use both influences of 3 pencils to dip 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 more or less the bundle twice.

You contribute unwind the original rubber bands also.) presently you have a large(p) 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 as vertical spacers, distant the rubber bands, separate each bundle into groups of 3. This will compose 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 self-colored 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.
