Patterns: Quick Trivia

Patterns in nature can sometimes be modeled mathematically to explain biological processes at different levels. Common patterns include symmetry, spirals, cracks, spots and stripes, and meanders. Examples of patterns found in nature are the Fibonacci sequence in plant spirals, minimal surfaces in soap films, snowflake structures, and mechanisms of morphogenesis in living organisms. Symmetry patterns include radial, bilateral, translational, scaling, and rotational symmetries. Spirals are found in galaxies, ferns, and other forms. Cracks form in materials like bark, lava, and bricks to relieve stress. Stripes and spots appear on animals like ladybugs and zebras. Meanders describe sinuous curves in streams and snakes

PATTERNS

Patterns in nature are visible regular forms found in the natural world. The
patterns can sometimes be modeled mathematically. Mathematics, physics and
chemistry can explain patterns in nature at different levels. Patterns in living
things express the underlying biological processes. 

Quick trivia

 Leonardo Fibonacci introduced the Fibonacci number sequence. It turns out


that simple equations involving the Fibonacci numbers can describe most of
the complex spiral growth patterns found in nature.

 The Belgian physicist Joseph Plateau (1801–1883) formulated the


mathematical problem of the existence of a minimal surface with a given
boundary, which is now named after him. He studied soap films intensively
and formulated Plateau’s laws, which describe the structures formed by films
in foams.

 The American photographer Wilson Bentley (1865–1931) took the first


micrograph of a snowflake in 1885.

 In 1952, Alan Turing (1912–1954), better known for his work on computing


and codebreaking, wrote The Chemical Basis of Morphogenesis, an analysis
of the mechanisms that would be needed to create patterns in living
organisms, in the process called morphogenesis

TYPES OF PATTERN

 Symmetry
- Exact correspondence of form and constituent configuration on opposite sides
of a dividing line or plane or about a center or an axis

Radial symmetry. Rotating this animal one-fifth of a turn doesn't change the
object, its pattern, or its appearance even though the positions of the arms have
changed. It is also an example of Fivefold symmetry

Starfish
Bilateral (mirror) symmetry is property of a pattern where each part
symmetrical with respect to its of which  is identical to the whole as
reflection. The butterfly and most seen at different magnifications. This
mammals are symmetrical along the is commonly called self similarity
main body axis

Time symmetry, such as the


Translational symmetry, such as periodic behavior of ocean waves or
repeating tiles or wallpaper patterns, music, involves changes in time.
means that a particular translation of Symmetry can also be a description of
an object to another location does not non-geometric forms such as time and
change its pattern. space

Scaling symmetry which is the

Waves

Threefold Symmetry Sixfold Symmetry

Fourfold Symmetry Fivefold Symmetry

 Spirals

A spiral is a curved pattern that


focuses on a center point and a series
of circular shapes that revolve around
it.

Galaxy Fern
 Cracks

Cracks are linear openings that


form in materials to relieve stress.

Bark of tree

Molten Lava

 Spots, stripes

Ladybugs

Zebra

 Meanders

Meander is one of a series of


regular sinuous curves, bends, loops,
turns, or windings.
