    Study Notes

    Mathematics in Our World: Unit 1 Overview

    • Explores patterns in nature and regularities in the world.
    • Examines the nature of mathematics: its expression, representation, and use.
    • Highlights the importance of mathematics in daily life and human endeavors.
    • Shows mathematics’ role in both societal progress and destruction.

    Lesson 1.1: Patterns and Numbers in Nature and the World

    • Nature by Numbers: A video explores mathematical patterns in nature.
    • Mathematical Regularities in Biology: Examples include tiger stripes and hyena spots illustrating patterns in biological growth.
    • Atmospheric Phenomena: Rainbows demonstrate light scattering, lunar halos reveal ice crystal shapes.
    • Astronomy and Physics: Planetary movements illustrate principles of gravity and motion.

    Natural Fractals and Spirals

    • Ammonites: Fossilized ammonite shells demonstrate spiral growth patterns.
    • Hurricanes: A self-organizing atmospheric spiral driven by water evaporation and condensation.
    • Spiral Galaxies: The largest natural spirals, comprising billions of stars.
    • Plants: Agave cacti and other plants demonstrate spiral growth patterns. Sunflowers and pinecones are also mentioned.
    • Fluid Motion: Turbulent fluid motion creates self-similar spirals.

    Geometric Fractals: Sierpinski Triangle

    • The Sierpinski Triangle is created by repeatedly removing the middle triangle, resulting in a pattern where the number of colored triangles increases by a factor of 3 with each step (1, 3, 9, 27...).

    Applications of Mathematics

    • Control Systems: Examples include thermostats, coppicing woodland, space shuttle launches, and electronic pacemakers.
    • Practical Applications: Mathematics underlies various aspects of daily life, such as vacation booking, flight scheduling, and TV signal transmission. It also plays a role in computer design, telephone lines, radar image processing, and special effects in television.
