    Study Notes

    Patterns in Nature and Mathematics

    • Mathematics is a tool for understanding patterns in nature and the environment.
    • Patterns are repeated designs or sequences; they can be sequential, spatial, temporal, or linguistic.
    • Regularity refers to the repetition of events under the same circumstances.
    • Patterns in nature exhibit visible regularities.

    Types of Patterns in Nature

    • Symmetry: Harmonious proportions and balance.
    • Spirals: Curves emanating from a point, moving outward as they revolve.
    • Meanders: A series of regular sinuous curves, as seen in rivers.
    • Waves/Riffles: Disturbances transferring energy through matter or space.
    • Foams/Bubbles: Substances trapping pockets of gas in liquids or solids.
    • Tessellations: Repeated geometric shapes covering a plane without overlaps or gaps.
    • Fractures/Cracks: Separations of an object into pieces due to stress.
    • Stripes and Spots: Series of bands or spots, often of the same width and color.
    • Fractals: Infinitely complex self-similar patterns at different scales.

    Uses of Mathematics in Different Fields

    • Technology: Navigation and prediction.
    • Engineering: Construction and robotics.
    • Media: Music, movies, and elections.
    • Medicine and Health: Pharmacy, surgery, and diagnostics (e.g., MRI).
    • Finance and Business: Banking, gambling, and data analysis. Many more including supply chains, insurance, loans, fraud detection, and pricing strategies are also impacted by mathematics.

    Number Patterns and Sequences

    • Fibonacci Sequence: Starts with 0 and 1; each subsequent number is the sum of the previous two (0, 1, 1, 2, 3, 5, 8...). Appears in nature (e.g., petal arrangements in flowers).
    • Finite Sequence: Has a first and last term.
    • Infinite Sequence: Has a first term but no last term.
    • Arithmetic Sequence: Each term is obtained by adding a constant difference (d) to the previous term. The formula to find the nth term is: an = a1 + (n – 1)d, where 'an' is the nth term, 'a1' is the first term, 'n' is the number of terms, and 'd' is the common difference.

    Golden Ratio

    • Denoted by the Greek letter Phi (φ), approximately 1.6180339887...
    • Found in various aspects of nature and art.
