the pattern remains the same. (Cornell)” Furthermore, there are Heesch tessellations which are 28 different types of asymmetric tiles which then are possible to tessellate, every single one in a different way. Escher used 27 out of these 28. Tessellations have two definitions. One is, “A plane tessellation is an infinite set of polygons fitting together to cover the whole plane just once, so that every side of the polygon belongs also to another polygon. No two of the polygons have common interior points. (Cornell)” and the other is, “ A tessellation is called regular if its faces are regular and equal. The same number of polygons meet at each vertex. We denote with n, k (called a Schläfli symbol) a regular tessellation that consists of regular polygons with n sides and at each vertex k edges meet. (Cornell)” So, from this, you can assume that in the Euclidean plane, there are only 3 possible tessellations, and they are, 3,6 where equilateral triangles meet six at each vertex, 4,4 where, instead of triangles, squares meet four at each vertex, 6,3where hexagons meet 3 at every vertex. This is true because the internal angle of a regular n-polygon is (1-2n). Since there are kedges that meet at every vertex, there’d be kinternal angles that add up to 2. So, because of this, we’d have: k (1-2n) =2 2k=1-2n1k+1n=12 in which k, n N This only has three solutions: n=3, k=6; n=4, k=4; n=6, k=3. Here is what they would look on a plane because visualising the results is much more…

The thing I disliked the most about English was irregular Verb. In Steven Pinker’s essay, Horton Heared a Who! The author presented an interesting idea regarding the linguistic development when one learned a new language. Professor Pinker introduced the idea that English verbs can be divided into two main types: The regular verb that could be conjugated with normal rules and other Verbs that need special conjugations. Those special verbs, Pinker believe, are difficult to pick up and learned and…

“Given a polygon, choose a minimum number of stations (points) in the polygon such that a mobile guard that visits all stations will guard the entire polygon.” [1] Furthermore, a polygon that can be guarded with an X number of stations is said to be lazy X guardable. Keywords: Lazy Guards, Simple Lazy Guards, Mobile Guards, Stations, Piecewise Linear Chain. Introduction The Lazy guard problem involves mobile guards and was first introduced by Paul Colly, Henk Meijer and David Rappaport. It…

Such as tiles on ceilings and floors, honeycombs in a beehive, brick walls, and checker boards. To create my project I used a curvy type shape all around that is very intricate no polygons were used. I first traced half the shape onto a paper then cut out that shape and taped it onto the opposite side going the same direction. I did this process twice until all sides could fold onto each other. There is one line of symmetry within my final…

remained much of a secret to the rest of the world and the continued use of pi was equivalent to 3. The next step in pi’s history was inscribing polygons into a circle to begin to compute its area. The first mathematicians that did this were Greeks known as Antiphon and Bryson of Heraclea however they were not able to get very far (Wilson). The reason they were not able to get far is it required a lot of work to continually make the polygon smaller and then gain the area of small triangles over…
