What is a regularity in the context of patterns in
nature?
A regularity is the fact that the
same thing
always happens in the
same circumstances.
View source
How is a pattern defined?
A
pattern
is a discernible regularity in the world or in a man-made design.
View source
What are patterns in nature?
Patterns
in
nature
are
visible patterns
found in the natural world.
View source
What does symmetry mean in the context of patterns?
Symmetry
means
agreement
in dimensions, due
proportion
, and
arrangement.
View source
What is a
spiral
?
A
spiral
is a
curve
which emanates from a point, moving farther away as it revolves around the point.
View source
What is a
meander
?
A
meander
is one of a series of
regular sinuous curves
,
bends
,
loops
,
turns
, or
windings
in the
channel
of a

What is a wave?
A wave is a disturbance that transfers energy through matter or
space
, with little or no associated
mass transport.

What is foam?
Foam
is
a substance formed by trapping pockets of gas in a liquid or solid.
View source
What is a tessellation?
A tessellation of a flat surface is the tiling of a plane using one or more geometric shapes, called
tiles
, with no overlaps and no gaps.
View source
What is a
fracture
?
A
fracture
or
crack
is the separation of an object or material into two or more pieces under the action of stress.

Stripes are made by a series of
bands
or strips, often of the same width and
color
along the length.
View source
What is a fractal?
A fractal is a
never-ending pattern
that is infinitely complex and
self-similar
across different scales.
View source
How are fractals created?
Fractals
are created by
repeating
a simple
process
over and over in an
ongoing feedback loop.
View source
What
are
affine transformations?
Affine transformations
are
the processes of rotation
,
reflection
,
and scaling.

What is the significance of the Fibonacci sequence in nature?
It is often associated with the ideal expansion pairs of rabbits over the course of
one year.
View source
What patterns can be observed in the Fibonacci sequence regarding even and multiple terms?
Every 3rd term is
even
, every fourth term is a multiple of three, and every
fifth
term is a multiple of five.
