&lt;p&gt;A series of (R Markdown) lessons built step by step: first the concept of the &lt;strong&gt;derivative&lt;/strong&gt;
as a rate of change, then &lt;strong&gt;exponential&lt;/strong&gt; population growth via a differential equation, and
finally the &lt;strong&gt;logistic&lt;/strong&gt; equation when space and resources impose limits. Best read in order.&lt;/p&gt;
