Study Notes

The Nature of Mathematics

Mathematics is the study of numbers, shapes, patterns, and quantities and their relationships
It is a systematic body of knowledge that focuses on specific areas of study.
Key areas of mathematics include: arithmetic, algebra, geometry, trigonometry, statistics, and calculus
Mathematics fosters human characteristics like creativity, reasoning, critical thinking, and spatial thinking.

Patterns in Nature

Visible regularities exist in the natural world, these are called patterns in nature.
Patterns are visible in various contexts and can be represented mathematically.
Some common patterns in nature include:
- Zebra stripes
- Sunflower
- Honeycomb
- Snowflakes
W. Gary Smith identified eight landscape patterns:
- Scattered
- Fractured
- Mosaic
- Naturalistic Drift
- Serpentine
- Spiral
- Radial
- Dendritic
These pattern occur in plants, animals, rock formations, river flow, stars, and human creations.

Waves and Dunes

Waves are forms of disturbance that carry energy as they move.
Mechanical waves travel through media, like air or water, causing oscillation.
Wind waves are surface waves created by energy passing through water, resulting in circular motion.
Ripple patterns and dunes are formed by sand wind as it passes over sand.

Spots and Stripes

Spots are visible on giraffes' skin.
Stripes are visible on zebras' skin.

Animal Movement

Symmetry of motion is observed in animal movements.

Sunflower

Sunflowers exhibit both radial and bilateral symmetry.
Ray florets are bilaterally symmetrical.
Disk florets are radially symmetrical.

Snowflakes

Snowflakes have six-fold radial symmetry.
Ice crystals are symmetrical.
The shape of each snowflake arm is similar to the others.

Fibonacci in Nature

Nature is inherently mathematical.
Fibonacci numbers appear in objects of varying sizes throughout the natural world.
Fibonacci numbers are found in flowers:
- 5-petal flowers (buttercups, columbine, hibiscus)
- 8-petal flowers (clematis, delphinium)
- 13-petal flowers (ragwort, marigold)

Fibonacci Sequence

Named after Leonardo Pisano Bigollo (1170 - 1250).
Discovered while studying rabbits.
Each number in the sequence is the sum of the two preceding numbers.
An infinite sequence.

The Golden Ratio

The golden rectangle is composed of squares whose sizes follow the Fibonacci sequence.
A spiral can be created within the golden rectangle, starting from one side of the first square and continuing to the edges of subsequent squares.
The spiral represents the golden ratio, approximately 1.618034.
The golden ratio can be observed in the golden spiral.
A natural example of a golden spiral is the Nautilus shell.

Mathematical Language and Symbols

Mathematics has its own language and uses symbols for communication.
Mathematical language consists of both natural language with technical terms and specialized symbolic notation.
Mathematical notation has its own grammar and is shared globally.

Characteristics of Mathematical Language

Precise: It expresses ideas clearly using defined symbols.
Concise: It communicates complex thoughts briefly.
Powerful: It expresses complex ideas in simpler forms.

Mathematical Expression and Sentence

Mathematical Expression: A combination of symbols that are well-defined according to rules. Does not state a complete thought or truth.
Mathematical Sentence: A combination of symbols that states a complete thought and can be determined as true or false.

Vocabulary and Sentences

Mathematics has its own vocabulary like any language.
Rules govern combining vocabulary into complete thoughts, creating mathematical sentences.

Connectives

Connectives like "+" are used to connect objects to create compound objects.
In English, "+" is similar to the connective "and".
