Al estar pintando mi tortuga me vinieron a la mente dos fascinantes temas que deseo compartirles. Uno es sobre "Tilings and Tessellations" y el otro es acerca del genio M.C. Escher, sin duda uno de mis artistas gráficos preferidos.Las tortugas han permanecido en la Tierra alrededor de 200 millones de años. Son de las especies más primitivas, pues ya vivían antes de que los dinousaurios evolucionaran; y han coexistido con muchas otras especies ya extintas. Habitan en todos los continentes, excepto en Antártica. Su conservación es una prioridad en México y en el mundo.
What are Tilings and Tessellations and how are they present in Nature?
"Tilings and tessellations are an important area of mathematics because they can be manipulated for use in art and architecture. Nature contains many different tessellations, some being arrangements of polygons. One artist in particular, MC Escher, a Dutch artist, incorporated many complex tessellations into his artwork. A tessellation is any repeating pattern of symmetrical and interlocking shapes. Therefore tessellations must have no gaps or overlapping spaces. Tessellations are sometimes referred to as "tilings". Strictly, however, the word tilings refers to a pattern of polygons (shapes with straight sides) only. Tessellations can be formed from regular and irregular polygons, making the patterns they produce yet more interesting."

...more interesting, YES! guess like who? LIKE TURTLES and other animals and fruits...isn´t wonderful?
M.C. Escher is easily recognized for his frequently mathematically inspired woodcuts, lithographs and mezzotints. His work boast impossible constructions, explorations of eternity, architecture and tessellations.

"Gravitation (also known as Gravity) is a mixed media work by the Dutch artist M.C. Escher which was completed in June, 1952. It was first printed as a black-and-white lithograph and then coloured by hand in watercolour. It depicts a nonconvex regular polyhedron known as the small stellated dodecahedron. Each facet of the figure has a trapezoidal doorway. Out of these doorways protrude the heads and legs of twelve turtles without shells, who are using the object as a common shell. The turtles are in six coloured pairs (red, orange, yellow, magenta, green and indigo) with each turtle directly opposite its counterpart." |
