    Study Notes

    Fibonacci Sequence

    • Discovered by Italian mathematician Leonardo Pisano while studying rabbit population growth.
    • Defined using the formula: ( F_n = F_{n-1} + F_{n-2} ), where ( F_n ) represents the nth term.
    • Generates numbers that illustrate fundamental natural processes, with no other natural counting systems outside its generated numbers.
    • Observed in sunflower seed arrangements, following a spiral pattern determined by Fibonacci numbers.
    • Other plants also exhibit growth patterns that align with the Fibonacci sequence.

    Symmetry

    • Symmetry can be split into two primary types: reflective symmetry and rotational symmetry.
    • Reflective symmetry creates a mirror image across a dividing line, exemplified perfectly by butterflies.
    • Rotational symmetry occurs when an object maintains its appearance through partial rotation, with circles being a classic mathematical example.
    • Many flowers and certain microorganisms from the Protozoa kingdom display significant rotational symmetry in their structures.

    Fractals

    • Fractals are patterns within Euclidean figures, where each part mirrors the statistical character of the whole figure.
    • Explained simply, they consist of recurring patterns at different scales within a geometric shape.
    • Tree branches exemplify fractals, as they replicate similar structures consistently throughout their growth.
