## Main Question or Discussion Point

From the book Calculus made easy: "This process of growing proportionately, at every instant, to the magnitude at that instant, some people call a logarithmic rate of growing."

From Wikipedia: "

Isn't the book Calculus made easy and Wikipedia page contradicting each other? Or have I misunderstood something here?

From Wikipedia: "

**Exponential growth**is feasible when the growth rate of the value of a mathematical function is proportional to the function's current value, resulting in its growth with time being an exponential function" from another Wikipedia page: " In mathematics,**logarithmic growth**describes a phenomenon whose size or cost can be described as a logarithm function of some input. e.g.*y*=*C*log (*x*)." "Logarithmic growth is the inverse of exponential growth and is very slow"Isn't the book Calculus made easy and Wikipedia page contradicting each other? Or have I misunderstood something here?
