+    <p>
+      This is an outline of the topics we covered in class.
+      These notes are <em>not</em> a substitute for your own note-taking.
+      I highly recommend that you take your own notes during class.
+      If you ever miss a class for any reason, reach out to another student in class to get a copy of their notes.

+        <p>
+          An experiment consists of planting 50 seeds in a garden, then growing them for 3 months.
+          Let <m>H_i</m> be the height of plant <m>i</m>.
