Study Notes

  • The slides present module 1 which includes topics on "Mathematics in our World" and "Fibonacci Numbers".
  • The objectives are to identify patterns and regularities in nature and the world, articulate the importance of mathematics in one's life, and express appreciation for mathematics as a human endeavor.

What Is Mathematics?

  • According to Stewart (1995), mathematics is a systematic approach of discovering the rules and structures behind observed patterns or regularities.
  • It utilizes these rules and structures to provide explanations
  • Aristotle defines mathematics as the science of quantity.
  • Comte defines it as the science of indirect measurement.
  • Benjamin Pierce describes mathematics as the science that draws necessary conclusions
  • The study of pattern and structure.
  • A useful way to understand nature and the world.
  • A tool to quantify, organize, control the world, predict phenomena, and improve life.

Where Is Mathematics?

  • Found in many patterns and occurrences in nature, the world, and life.
  • Mathematics helps give sense to these patterns and occurrences.
  • Mathematics helps organize patterns and regularities in the world
  • Mathematics helps predict the behavior of nature and phenomena in the world.
  • Examples of where mathematics can be found are images of the stars shown on the 11th slide, snowflakes from the 12th slide, and animal patterns from the 13th slide.
  • It is mathematically possible to describe nature.
  • The beauty of a flower, a tree, and even rock formations exhibit nature's sense of symmetry.
  • Paul Dirac stated that "God used beautiful mathematics in creating the world."

Fibonacci Numbers

  • Leonardo Pisano Fibonacci, also Leonardo of Pisa, was an Italian mathematician who introduced the world to Arabic numbering (now known), square roots, number sequencing, and math word problems.
  • In 1202, Fibonacci proposed a puzzle about a man who put a male-female pair of newly born rabbits in a field.
  • The questions posed was how many rabbit pairs would be there after one year

Fibonacci Numbers in Real Life

  • Petal arrangements in flowers
  • Bees constructing honeycombs
  • Tree branches
  • Shell structures
  • Pinecones
  • Financial markets
  • Pascal's Triangle
  • Paintings
  • Fibonacci numbers are numbers in the Fibonacci sequence.
  • Every number after the first two is the sum of the two preceding ones.

What is the Golden Ratio?

  • Taking the ratio of two successive numbers in Fibonacci's series tends to approach a specific value.
  • The golden ratio is the ratio of a line segment cut into two pieces of different lengths.
  • The ratio of the whole segment to the longer segment equals the ratio of the longer segment to the shorter segment.
  • The golden ratio is also called the Divine Proportion
  • The golden ratio is sometimes known as the golden mean or golden section.
  • The Egyptians referred to it as the "sacred ratio."
  • The golden ratio is denoted by Phi (Φ) or φ.
  • The golden ratio is approximately equal to 1.6180339887

Fibonacci Poem (FIB)

  • Goal is to collaborate with a partner to write a six-line FIB and express appreciation of Fibonacci numbers as applied in poetry.
  • A Fibonacci poem is a form of poetry where the number of syllables in each line must equal to the sum of the syllables in the two previous lines
  • Gregory K. Pincus created this form of poetry that plays off the mathematical Fibonacci sequence.
  • Fib, or fibonaiku, is an experimental Western poetry form bearing similarities to haiku but based on the Fibonacci sequence.
  • A typical fib is a six-line, 20-syllable poem with a syllable count by line of 1/1/2/3/5/8.

Syllables for Six-Line Poem

  • 1 syllable for the first line
  • 1 syllable for the second line
  • 2 syllables for the third
  • 3 syllables for the fourth
  • 5 syllables for the fifth
  • 8 syllables for the sixth
