The Nature of Mathematics – Lecture Overview

Vocabulary flashcards covering the key concepts, terms, and applications discussed in the lecture on the Nature of Mathematics.

Mathematics (Classical View)

Science of numbers and their operations, interrelations, combinations, generalizations, and abstractions.

Mathematics

Study of patterns, structures, and logical relationships using symbols and rules.

Mathematics (Practical View)

Language of the universe—a system for understanding the world quantitatively and logically.

Mathematics as a Language

Use of symbols, notation, and logic to describe real or abstract phenomena and communicate ideas.

Mathematics as a Science

Process that involves observation, abstraction, reasoning, forming hypotheses, proving theorems, and modeling systems.

Mathematics as an Art

Creative and aesthetic aspect of math expressed through symmetry, fractals, and elegant proofs.

Mathematics as a Tool

Practical instrument for solving real-world problems in fields such as budgeting, coding, and medicine.

Golden Ratio

Special ratio (~1.618, denoted φ) where a line is divided so that the whole to the longer part equals the longer to the shorter.

Phi (φ)

Symbol for the Golden Ratio, an irrational number approximately equal to 1.618033988…

Golden Face Ratio

Application of the Golden Ratio to human facial measurements; ideal facial proportions approach 1.618.

Golden Spiral

Logarithmic spiral that grows outward by the Golden Ratio; often used for composition in art and photography.

Symmetry

Transformation (reflection, rotation, translation) that leaves an object looking the same; examples: three-fold spiderwort, five-fold starfish.

Pattern

Regular, repeated, or recurring form or design found in mathematics and nature.

Sequence

Ordered list of numbers that follow a specific rule (arithmetic, geometric, Fibonacci, etc.).

Arithmetic Sequence

Sequence that adds the same number each time (e.g., 2, 4, 6, 8 …).

Geometric Sequence

Sequence that multiplies by the same factor each time (e.g., 3, 6, 12, 24 …).

Fibonacci Sequence

Sequence where each term equals the sum of the two preceding terms (0, 1, 1, 2, 3, 5 …).

Fibonacci's Rabbit Problem

Classic problem from Liber Abaci that models rabbit population growth and introduces the Fibonacci Sequence.

Vitruvian Man

Leonardo da Vinci drawing illustrating human body proportions that fit within a circle and square, demonstrating mathematical harmony.

Mathematics for Our World

Use of mathematics to organize patterns, predict natural behavior, and control phenomena for societal advancement.
