In other words, you would make a little bit more every year.
Those systems might be a population of bacteria, a chemical reaction, or the decay of a radioactive material.
While other factors may reduce the growth rate, that equation would describe the upper limit.
The type of equation that describes the type of growth that increases over time is an exponential equation, introduced in our module Exponential Equations in Science I: Growth and Decay.
The last figure I heard was that there are currently eight nuclear subs on our ocean floors. It doesn't work for sea creatures and other things that are under water. Then they measure how much is left in the specimen when they find it.
It comes from cosmic rays that rain down on the earth (and us) from outer space.
