  2. Patterns in nature - Wikipedia

    en.wikipedia.org/wiki/Patterns_in_nature

    Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically . Natural patterns include symmetries , trees , spirals , meanders , waves , foams , tessellations , cracks and stripes. [ 1 ]

  3. Turing pattern - Wikipedia

    en.wikipedia.org/wiki/Turing_pattern

    Three examples of Turing patterns Six stable states from Turing equations, the last one forms Turing patterns. The Turing pattern is a concept introduced by English mathematician Alan Turing in a 1952 paper titled "The Chemical Basis of Morphogenesis" which describes how patterns in nature, such as stripes and spots, can arise naturally and autonomously from a homogeneous, uniform state.

  4. Logarithmic spiral - Wikipedia

    en.wikipedia.org/wiki/Logarithmic_spiral

    A logarithmic spiral, equiangular spiral, or growth spiral is a self-similar spiral curve that often appears in nature. The first to describe a logarithmic spiral was Albrecht Dürer (1525) who called it an "eternal line" ("ewige Linie").

  5. Spiral - Wikipedia

    en.wikipedia.org/wiki/Spiral

    A model for the pattern of florets in the head of a sunflower [13] was proposed by H. Vogel. This has the form =, = where n is the index number of the floret and c is a constant scaling factor, and is a form of Fermat's spiral.

    [27] [28] Diophantus solved some equations involving unknown natural numbers by deducing new relations until he obtained the solution. [29] Al-Khwarizmi introduced systematic methods for transforming equations, such as moving a term from one side of an equation into the other side. [30]

  7. Fibonacci sequence - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_sequence

    Singh cites Pingala's cryptic formula misrau cha ("the two are mixed") and scholars who interpret it in context as saying that the number of patterns for m beats (F m+1) is obtained by adding one [S] to the F m cases and one [L] to the F m−1 cases. [12] Bharata Muni also expresses knowledge of the sequence in the Natya Shastra (c. 100 BC–c ...

  8. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

  9. Pascal's triangle - Wikipedia

    en.wikipedia.org/wiki/Pascal's_triangle

    Pascal's triangle has many properties and contains many patterns of numbers. Each frame represents a row in Pascal's triangle. Each column of pixels is a number in binary with the least significant bit at the bottom. Light pixels represent 1 and dark pixels 0. The numbers of compositions of n +1 into k +1 ordered partitions form Pascal's triangle.
