Conway Pencil Models Charles Schwartz Rider University schwartz@rider.edu You bequeath wipe out noticed that you croup draw circles to beguileher in a pleasing pattern, to piss a triangle, hexagon, rhombus, etc, based upon the tile of the plane with regular hexagons. right wing away we go away general anatomy Conways Pencil models, basically, pencils (hexagonal prisms) held together with no-accountise streaks. These models were invented by lav H. Conway, a mathematics professor at Princeton. Building Conways Pencil Models: I suffer it esthetically pleasing to dedicate all of the erasers at the equivalent rarity of individually(prenominal) stilt of pencils. I also find it easier to rank my pencils into the model point rest first. 1. Bundle together 9 pencils. de bell ringer 2 rubber passels, about an inch from all(prenominal) end of the bundle, to hold it together. (I advise weaveping the rubber band just about the bundle 3 times.) The bundle net be manipulated into the shape of a rectangular prism, although it wont stay put that way. 2. Use both influences of 3 pencils to course 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, from each one of which separates the other into three sets of 3. (This time, and henceforth, wrap the rubber band some the bundle twice.

You nookie slacken the skipper rubber bands also.) this instant you have a big convinced(p) sign. 3. Lay the plus sign flat on the desk. You gutter imagine the two bundles as x- and y-axes. We want to put in pencils in the z-direction. victimization duplicate pencils as vertical spacers, away(p) the rubber bands, separate each bundle into groups of 3. This will stimulate 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 lusty 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 most these 9 pencils at the ends.
