Give people everyday examples:
- Linear growth: Adding 1 unit of speed every year (a line on a regular x-y graph)
- Exponential growth: Doubling every 24 months (a curve on an x-y graph, a line on a log graph)
- “Linearly growing” exponential growth: Doubling every 24 months, then every 23 months, then every 22 months… (a steeper curve on a regular graph, and still a curve on a log graph. A line on a log-log graph). (The rate of doubling is changing). What is the proper name for this?
- Beyond that? Wow! Doubling every 24 months, then 12 months, then 6 months, then 3 months…
