The science of patterns and relationships, evolved from elemental practices of counting, measuring, and describing the shapes and characteristics of objects
Patterns
Visible regularities of form found in the natural world, that recur in different contexts and can sometimes be modelled mathematically
Regularity
The fact that the same thing always happens in the circumstances
Symmetry
A sense of harmonious and beautiful proportion and balance, where an object is invariant to various transformations including reflections
Two Main Types of Symmetry
Bilateral Symmetry
Radial or Rotational Symmetry
Bilateral Symmetry
A symmetry in which the left and right sides of the organism can be divided approximately mirror image of each other along the midline
Radial or Rotational Symmetry
A type of symmetry around a fixed point known as the center, which can be classified as cyclic or dihedral
Radial or Rotational Symmetry
Starfish has a five-fold symmetry with an angle of rotation of 72°
Solving for the angle of rotation of patterns
Determine the angle of rotation for given patterns
Spiral
A curve which emanates from a point, moving farther away as it revolves around the point
Wave
A disturbance that transfers energy through matter or space, with little or no associated mass transport
Foam
A substance formed by trapping pockets of gas in a liquid or solid
Tessellation
Tiling of a plane using one or more geometric shapes called tiles with no overlaps and no gaps
Fracture or Crack
Separation of material into two or more pieces under the action of stress
Stripes
Made by a series of bands or strips, often of the same width and color along the length
Fractals
A never ending pattern, consisting of infinitely complex patterns that are self-similar across different scales in loop
Exponential growth model
A = Pert, where A is the size of the population after growth, P is the initial number of people, e is Euler's constant, r is the rate of growth, and t is time in years
Solving population growth problems
Use the exponential growth model to find the population size at a given time
Fibonacci Sequence
A sequence where each number is the sum of the two preceding ones
