+<h1>Calculus</h1>
 <p>
-	The following are the groff source files to all my notes:
+Calculus is the age-old study of infinetesimal rates of change.
+I write articles here from the perspective of hyperreal numbers
+instead of using limits because they were the original intuitive
+way that calculus was invented (and how I originally reinvented
+the derivative).
 </p>

+	You can also <a href="./source">browse the groff source files</a>,
