Patterns in Nature

Symmetry is prevalent in nature, from the mirror images of leaves and butterflies to the symmetrical forms of trees and the fractal patterns found in many natural systems.
Spirals are ubiquitous, visible in the formations of mountains, clouds, rivers, and coastlines, and also in the arrangement of curved patterns like hurricanes, galaxies, and whirlpools.
Waves and dunes exhibit long, straight lines, often resembling stars, domes, or parabolas, illustrating the consistent patterns underlying nature's movement.
Bubbles and foam demonstrate a fascinating pattern of repetition, extending beyond just physical forms to also occur at the cellular level and within the formation of foam patterns.
Tessellations, intricate patterns formed by interlocking shapes, are a recurring theme in nature, exemplified by the patterns in cracks.
Cracks, often appearing as areas, spots, or stripes, serve purposes such as providing camouflage, representing evolutionary adaptations, and highlighting patterns in the distribution of stresses within materials.
The Fibonacci sequence is a mathematical series discovered by Leonardo Pisano Bigollo (1170-1250), also known as Fibonacci, where each number is the sum of the two preceding ones (e.g., 0, 1, 1, 2, 3, 5, 8, 13).

Qualitative vs Quantitative Data

Qualitative data focuses on categories and descriptions, with four main types:
- Nominal: Categories with no inherent order (e.g., colors, fruits, names).
- Ordinal: Categories with a ranked order (e.g., ABCDF grades, rankings in a competition).
- Interval: Categories with equal intervals but no true zero point (e.g., temperature, IQ).
- Ratio: Categories with equal intervals and a true zero point (e.g., height, weight, time, age).
Quantitative data focuses on numerical measurements and can be categorized into two main types:
- Discrete Variable: Values can only be whole numbers (e.g., number of cars in a parking lot).
- Continuous Variable: Values can include any number, including fractions and decimals (e.g., height, weight).

Qualities of Variables

Exhaustive variables encompass all possible answers or outcomes within a given context.
Mutually Exclusive variables ensure that events cannot occur simultaneously. For instance, a person cannot be classified as both "male" and "female" in a gender analysis.

Deductive & Inductive Reasoning

Deductive reasoning starts with a general statement and uses logic to reach a specific conclusion (e.g., "All humans are mortal. Socrates is human. Therefore, Socrates is mortal").
Inductive reasoning starts with specific observations and uses them to form a general conclusion (e.g., "The first three swans I saw were white. Therefore, all swans are white").
