-<h1>Mathematics</h1>
+<h1>Differential Equations</h1>
 <p>
-	Mathematics is the basis for the analysis of things that we
-	believe to adhere to our logical system.
+	Differential equations describe how things in our universe change. They come up
+	as fundamental equations in all models of our universe, and they also describe
+	change on more macro levels as well. Understanding differential equations gives
+	you one of the most powerful tools in mathematics.
