Barchans or crescent dunes are produced by wind acting on desert sand; the two horns of the crescent and the slip face point downwind. Sand blows over the upwind face, which stands at about 15 degrees from the horizontal, and falls onto the slip face, where it accumulates up to the angle of repose of the sand, which is about 35 degrees. When the slip face exceeds the angle of repose, the sand avalanches, which is a nonlinear behaviour: the addition of many small amounts of sand causes nothing much to happen, but then the addition of a further small amount suddenly causes a large amount to avalanche. [69] Apart from this nonlinearity, barchans behave rather like solitary waves. [70] First up is Cyanthiform. A Cyanthiform flower is shaped like a cup of a bowl. It has radial or actinomorphic symmetry. The petals curve upwards, forming the bowl shape. Exploring Nils Udo’s work with your students is a compelling way to have a conversation about intertwining life and art. Student can also discuss photographing natural moments in nature versus putting natural elements together to create art. Lewalle, Jacques (2006).

Vincent Van Gogh, a Post-Impressionist Dutch painter, painted in relative obscurity until after his death, whereupon his paintings began to achieve widespread popularity. One of the most famous paintings of Van Gogh is “The Starry Night”, which he created in June of 1889. Fractal-like patterns occur widely in nature, in phenomena as diverse as clouds, river networks, geologic fault lines, mountains, coastlines, [43] animal coloration, snow flakes, [44] crystals, [45] blood vessel branching, [46] Purkinje cells, [47] actin cytoskeletons, [48] and ocean waves. [49] Miranda Lloyd is an incredible artist who does both graphic design and traditional art. Many of her works focus on trees and animals. When viewing her trees, you will see a wide range of textures, lines, shapes, and colors. She also tends to create mixed media pieces.Sometimes they will paint indoors, relying on their imaginations and feelings to guide the works of art they create. From landscapes, animals, gardens, rivers, seascapes and more, artists have a wide variety of natural subjects to depict in their works.

Richard Long started creating art in 1945 and is still creating his works of art inspired by nature today. He is known for sculptures and installations with natural elements at his many exhibitions. He even has worked with mud! Henri Rousseau, a French Post-Impressionist painter who worked in the so-called “Primitive” manner, was a self-taught artist who may be best known for his depiction of scenes of jungles. He famously claimed that he has “no teacher other than nature.” Schwämmle, V.; Herrman, H. J. (11 December 2003). "Solitary wave behaviour of sand dunes". Nature. 426 (6967): 619–620. Bibcode: 2003Natur.426..619S. doi: 10.1038/426619a. PMID 14668849. S2CID 688445. Andy Goldsworthy makes art out of natural elements such as twigs, leaves, stones, snow, reeds, and thorns. He sees his practice in art with nature as a collaboration. The main thing to bear in mind, as your head spins with the variety of flower shapes, is what it’s all for. The diversity and beauty of these structures comes down to pollination, and attracting pollinators to a flower. As Candace Galan states in the article “ Why do Flowers vary? “Nearly all botanists give animal pollinators credit for the vast smorgasbord of flower shapes and sizes observed in nature.” However, as she point out, other environmental factors are also involved, as are a plant’s enemies and the costs of producing these amazing flowers.

Ball, Philip (2009b). Nature's Patterns: a tapestry in three parts. 2: Flow. Oxford University Press. In mathematics, a dynamical system is chaotic if it is (highly) sensitive to initial conditions (the so-called " butterfly effect" [60]), which requires the mathematical properties of topological mixing and dense periodic orbits. [61] Labiate flowers have lips, or are lipped. The flowers look like a throat with an upper an lower lip, resembling a mouth They tend to have long, fused corolla tubes with an enlarged lower lip. Labiate flowers show bilateral or zygomorphic symmetry.

Calceolate flowers are very distinctive, and it’s an uncommon shape. The term translates from the latin as shoe-like, or slipper-like. The only examples of calceolate flowers I can think of are the slipper orchids, none of which I’ve illustrated. Calceolate flowers are bilaterally symmetrical, so they are zygomorphic. a b c Rozenberg, Grzegorz; Salomaa, Arto. The Mathematical Theory of L Systems. Academic Press, New York, 1980.

For example, a crystal is perfect when it has no structural defects such as dislocations and is fully symmetric. Exact mathematical perfection can only approximate real objects. [25] Visible patterns in nature are governed by physical laws; for example, meanders can be explained using fluid dynamics. Although we can all step outside and study rose pedals and the intricate details of a leaf with our own eyes, we can discover a whole different feeling or detail in an artists’ perception of the very same subjects. Numerous artists from the past have focused their art work on their environment, the days’ changing lights and the nights’ play of shadows, but there are a few in particular that really stand out.
