non-linearity

Non-linearity refers to situations where change doesn't happen in a straight-line manner. Instead of a direct proportion—where doubling one thing leads to doubling another—non-linear systems react in more complex ways. For instance, in ecosystems, small changes can lead to dramatic shifts, like a population boom or collapse. Non-linearity is common in nature and human behavior, affecting everything from weather patterns to economics. Understanding non-linearity helps us grasp how interconnected variables can lead to unexpected outcomes, making it essential in fields like science, engineering, and finance.
