    Many have questions like what are tessellations? Tessellations are the arrangement of small squares in a checkered or mosaic form. Tessellations are seen all around, but yet you don't notice them. Tessellations can be found in your house from the tiles in bathrooms, or even to the honeycomb of bees. There was a famous man with the name of M.C. Esher, and he was the first to use these tessellations in artwork. He became well known for them and being the first one to use them M.C. Esher became really popular. Tessellations means to form or arrange small squares in a checkered pattern, tessellation comes from the greek word tesseres which means four. Tessellation and tiling are both the same thing, they both are repetitive of patterns of the same shape with no overlapping or gaps. As an art form, tessellation is particularly rich in mathematics, which ties into geometry, topology, and group theory. There are monohedral tessellations, mono meaning one and hedral meaning shape. Monohedral tessellations are made up of one shape, the shape can be rotated or flipped. M.C. Esher become very popular from using monohedral tessellations. There are also aperiodic tessellations, these are patterns exhibit five fold symmetry, a pattern that is not found in any periodic pattern. Medieval islamic architecture is particularly rich in aperiodic tessellations. These patterns and work of arts had been used in the past five hundred years and are still popular today. The geometries within the…

    Tessellations , Tessellations are a arrangement of shapes closely fitted together , especially of polygons in a repeated patterns without gaps or overlapping . They make really pretty designs if you do it right . Another word for Tessellations is “tiling”.Tessellations are catching to the eye and they are found in the regular everyday patterns such as , bathroom floors , backsplashes , turtle shells , honeycombs, raspberries, quilts and fish . “Tessellations are also widely used in the design of…

    M.C. Escher’s art has always been fascinating to look at; his tessellations especially. I was first introduced to him by my psychology teacher when we looked at optical illusions, and then, once again in art class when he was introduced as an amazing artist, rightfully so. Being a fan of his art, I was amazed to find I could translate it in math terms as well; tessellations turn into geometric ratios and formulas. From psychology, to art, to math, M.C. Escher’s art has been widely acclaimed as…

    Essay On Leonhard Euler

    • 2361 Words
    • 10 Pages

    Euler stated his amazing observation and described his astonishment that no one else had noticed the general properties of solid geometry he found. This observation that Euler described in his letter is what we not call Euler’s polyhedron formula. [10] Polyhedrons are defined as being three-dimensional solids formed by polygons that are usually joined at their edges. [14] These polyhedrons consist of their flat polygons which we call faces, the line segments where adjacent faces meet called…

    Escher exploited those three shapes, building on math’s premise, to create image, and yet he followed the basic three, four, or six-fold patterns of symmetry still to create more detailed and mathematically correct designs. Utilizing isometry, Escher was able to explore math in ways that mathematicians never would have, exploring the realms that they had discovered. He also used polyhedrons, the regular solids, in his work. He combined these at times, intersected them, made them appear like…

    Petersburg Academy of Science in Russia and also worked in the Russian Navy from 1727 to 1730 as a medical lieutenant. At the Academy, Euler served as professor of physics in 1730. Three years later, he became a professor of mathematics. Euler wrote many articles during his lifetime. His book “Mechanica” earned him worldwide fame as a prominent mathematician. It depicted Newtonian dynamics in the form of mathematical analysis (famousscientists.org) His most famous equation associated with…

    In the three dimensional tetrahedral coordination polyhedron such as SiO2 the value of the d ratio is 3 and in the two dimensional layer structures it equals 2. The second important parameter is the ratio G/C12 (58), which considered as an indicator of the character of the force field. This parameter equals to 1 in case of the central force type; otherwise the force is not central. On the other hand, the G/C12 ratio approaches to unity as the central force field may reduce the fraction of the…

    The Alchemist: Democritus

    Protagoras believed that the tangent did not touch a sphere at one point but over a distance, but Democritus treated a sphere to being made of all angles (“Democritus”). That meaning a sphere is bent all over making it all angles. “Democritus believed the circle was actually a polyhedron with small faces because a sphere involves atoms which cannot be broken down.” (“Democritus”). His thought that atoms have variety of shapes should mean he could make a sphere with indivisible magnitude and…
