Exponential Growth

A pattern of growth where a quantity increases at a rate proportional to its current value, characterized by rapid acceleration over time.

Exponential Growth

Exponential growth describes a fundamental pattern in which a quantity grows at a rate proportional to its current size, leading to increasingly rapid expansion over time. This powerful mathematical concept appears throughout nature, technology, and human systems.

Mathematical Foundation

The basic mathematical expression of exponential growth is:

  • N(t) = N₀ × e^(rt)
  • Where:
    • N(t) is the quantity at time t
    • N₀ is the initial quantity
    • r is the growth rate
    • e is Euler's number
