This eagle at Mkhuze Game Reserve in KwaZulu-Natal is ruffling its feathers and looking uncharacteristically frilly, in a photo that is somewhat grainy because it was taken at quite a distance. He was particularly curious about how an embryo could develop from a few identical cells into a striped or spotted animal with specialized body parts. The researchers found that the amount of water and evaporation affected the creation of the patterns and how pronounced they appeared. Some patterns are as small as the molecular arrangement of crystals and as big as the massive spiral pattern of the Milky Way Galaxy. In 1952, he published a paper, The chemical basis of morphogenesis, presenting a theory of pattern . While each of these complex systems has nothing in common, it appears that there is a mathematical pattern in the complex data that is yet to be explained. I think it is similar in Jhb? The size and shape of the pattern (called a Turing pattern) depends on how fast the chemicals diffuse and how strongly they interact. Animal behavior: patterns observed in animal behavior, such as the production of hexagons in honeycombs, are often the result of genetics and the environment. I have never seen ladybirds congregating like that here, perhaps the winters are not cold enough. Science World's feature exhibition,A Mirror Maze: Numbers in Nature, ran in 2019 and took a close look at the patterns that appear in the world around us. In fact the formation of patterns and shapes in nature and their regulation, a process known as morphogenesis (literally the formation of a bodys shape), was the subject of a study by Alan Turing, who was a mathematician involved also in other academic disciplines and theoretical and practical fields of study. I suppose that as much as they need to conceal themselves from prey, they also need to conceal themselves from other predators to avoid being prey themselves! I hope yours picks up soon. I was truly mezmerized by the African martial eagle never seen one before. Best known for cracking enigma code in ww2.. in hollywood films, sure, while over in reality, he's known as the creator of modern computing Of which one application was code cracking Agree completely with @shaunshaun. So, perhaps, we can think about our fingers and toes in the same way that we think about stripes! Included in Felimormia, along with cats and hyenas are mongooses, genets, Malagasy carnivores, civets and Asiatic linsangs (I had to look them up). They out-compete native species and have been shown to be more resilient/adaptable in the face of rising temperatures due to climate change. Patterns in nature ~ Everything You Need to Know with Photos | Videos Turing was a British mathematician perhaps best known for cracking the German Enigma code during World War II that helped lead to Allied victory over Nazi Germany. Suburban garden His "reaction-diffusion" model uses a two-protein system to generate a pattern of regularly-spaced spots, that can be converted to stripes with a third external force. This is formidable eye candy for the I-love . . Vervet monkeys As discussed earlier, during an organism's development, chemicals called inhibitors and activators interact to produce the resulting pattern. Some of these patterns are uniform, such as in tessellations, and some of these patterns appear chaotic, but consistent, such as fractals. The model may explain the chemistry behind how a zebra gets its stripes and why grasses can grow in patches. There are South African research projects on the go on ways to control them , Oooooooooooooo What a wonderful post. Thanks very much Saurab. Fractals are infinitely self-similar, iterated mathematical constructs having fractal dimensions. Hiscock and Megason propose four main ways to get a stripe pattern. This one I photographed while it was resting on the grass at Kirstenbosch National Botanical Garden in Cape Town.

Last summer Brendan D'Aquino (opens in new tab), a computer science undergrad at Northeastern University in Boston, worked with Flavio Fenton (opens in new tab), a professor of physics at Georgia Tech, in his lab as part of a summer internship to test Turing's theory. At the same time, it activates the inhibitor, which also diffuses away from the point source, inhibiting the activator. We are now experiencing heavy rain after very intense heat. A mathematical model first proposed by Alan Turing 71 years ago may have finally been confirmed by chia seeds sprouting in a lab. Line patterns in nature are linear in design. What a fascinating post, Carol, and the photography is superb! Covid-19 Computational models predict that this type of gradient causes stripes to orient themselves perpendicular to the gradient (Figure 2)2. For the first time, scientists using chia seed experiments have confirmed that Alan Turing's mathematical model can explain patterns seen in nature. Indigenous garden KwaZulu-Natal First, there must be random fluctuations in expression that turn the activator on at low levels across a tissue. The small grass jewel butterfly (Freyeria trochylus formerly Chilades trochylus) has an exquisite pattern that abounds with dots. Live Science is part of Future US Inc, an international media group and leading digital publisher. Spotted cats are perhaps the most famous representatives of dot patterns in nature. Thanks also for the good wishes I hope too that you have a lovely weekend. Patterns in nature - Wikipedia Most spirals found in nature that are formed by forces, such as the hurricanes or galaxies, are not Fibonacci or Golden Ratio spirals as the angles of the spirals are uniform in force-created phenomena. Frieze Pattern Types & Overview | What is a Frieze Pattern? In some ways, foams can be fractal. Spotted or not their conspicuous colour serves as a warning to predators that they are toxic to eat.
