Study Notes
The Fibonacci Sequence
- Introduced by Leonardo Pisano Bigollo, also known as Fibonacci, who lived from 1180 to 1250.
- The sequence starts with the numbers 1 and 1; each subsequent number is the sum of the previous two: Fn = Fn-1 + Fn-2.
- The sequence progresses as follows: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc.
- Fibonacci numbers are found in various natural phenomena, including the arrangement of leaves and the branching of trees.
Patterns and Numbers in Nature
- DNA structure embodies Fibonacci dimensions: length of 34 angstroms and width of 21 angstroms.
- The Great Wave off Kanagawa illustrates natural patterns that resonate with mathematical concepts.
- Patterns in nature often display repeated sequences and symmetry, exemplifying mathematical principles.
Mathematics for Humankind
- Mathematics is integral to addressing challenges in human activities and natural occurrences.
- Problem-solving through mathematical principles applies to social and cultural practices.
Ethnomathematics
- Focuses on the diverse mathematical practices across different cultures.
- Highlights how various societies utilize mathematics to solve unique issues and maintain cultural identities.
Fractals
- Fractals exhibit self-similarity, allowing them to be zoomed in on infinitely while retaining their overall shape.
- Key fractal properties include fractional dimensions, which are not confined to integers, and formation through iteration, a repeating process.
- Examples include the Koch Snowflake, Sierpinski Triangle, and the Cantor Set.
Isometries, Symmetries, and Patterns
- Transformation refers to shifting points within a plane to new locations and can include translation, reflection, and rotation.
- Rigid transformations maintain the object’s dimensions, while non-rigid transformations can alter size and shape.
- Symmetry exists if a figure can be mapped onto itself through a non-trivial transformation.
Patterns in Design
- Rosette patterns involve rotating and reflecting motifs, common in designs like mandalas.
- Patterns can exhibit various symmetries, including cyclic (n-fold rotational symmetry without reflectional symmetry) and dihedral (n-fold rotational with reflectional symmetry).
- Frieze patterns are indefinite strips with repeating designs, revealing continuous mathematical relationships in art and nature.
Mathematical Principles in Patterns
- Different transformations in patterns can include glide reflections (slides combined with reflection), spins, and horizontal/vertical reflections.
- A variety of transformation combinations can result in intricate and symmetric designs, showcasing the mathematical underpinnings of aesthetics in culture.
