Study Notes
Patterns and Numbers in Nature and the World
- A pattern is a predictable regularity in the world, design, or abstract ideas.
- Symmetry is a regularity characterized by operations that leave an object unchanged.
- Reflection (line or mirror symmetry) maps points across a line at equal distances.
- Bilateral symmetry is a reflection with one mirror axis, dividing an organism into two equal halves.
- Rotation symmetry fixes one point (rotocenter) and rotates everything around it by a set angle. Examples include tiger stripes and hyena spots, which serve camouflage purposes.
Fibonacci Sequence
- The Fibonacci sequence starts 1, 1, and each following number is the sum of the two preceding numbers (e.g., 1, 1, 2, 3, 5, 8, 13...).
- Fibonacci's original problem (1202, Liber Abaci) concerned rabbit breeding under ideal conditions.
- The Fibonacci sequence is defined by the recurrence relation Fn = Fn-1 + Fn-2, with F1 = 1 and F2 = 1.
- The Fibonacci sequence appears in nature, such as in the arrangement of petals in flowers (e.g., lilies have 3, daisies have 34, 55, or 89 petals), pine cones, and sunflower seed spirals (e.g., 21 counterclockwise, 34 clockwise).
- The arrangement of these spirals often relate to Fibonacci numbers.
- Fibonacci numbers are also seen in the spiral pattern of seashells.
Golden Angle
- The golden angle is the smaller angle created by dividing a circle's circumference according to the golden ratio (approximately 137.50776°).
- The golden angle is related to the arrangement of leaves and florets in some plants, maximizing light exposure.
Importance of Math in Life
- Mathematics helps organize patterns and regularities in the world, both numerical (like Kepler's planetary laws where d³/o² = constant) and geometric (e.g., circles in rainbows and ripples, icosahedral shape of viruses).
- Mathematics helps predict the behavior of nature and the world (e.g., lunar and solar eclipses, tides).
- Mathematics helps control nature and occurrences for our own ends (e.g., mathematical modeling in controlling disease spread).
