<h2> September 21 </h2>
<section class='update-description'>
<section class='primary'>
<p> Words of encouragement! This is a short note that most students will read. </p>

</section>
<p><h3>Primary versus Secondary Updates:</h3> Unfortunately, the internet throws a lot of text at students, and they
do not read everything that they are given. However, many students <em>do</em> read all that they are
given, and so detailed explainations in this section will benefit the most concientious.
Any essential information should be extremely quickly summarized in the primary section for skimmers.</p>
<p><h3>Star Forum Poster</h3>
Students appreciate knowing that the course staff is reading what they post, and one of several ways
that you can do this is by acknowledging the star posters in your announcements.

<!-- You can include %%USER_ID%% to include an anonymized user ID in your outside services so that you can relate them later.
This example is a Qualtrics template:
- Replace the "###############" with your Survey ID.
- Also replace "YOUR_UNIVERSITY" with your qualtrics ID.
- Finally, replace "YOUR_LINK_TEXT" with your link text.
- If you wish to embed your survey into the courseware instead of opening a new tab, replace the above HTML with what is provided below.

\subsection{Example of E-text in LaTeX}
It is very convenient to write complex equations in LaTeX.
\begin{equation}
x = \frac{-b\pm\sqrt{b^2-4*a*c}}{2a}
\end{equation}
Seize the moment.

<h2>ZOOMING DIAGRAMS</h2>
<p>Some edX classes use extremely large, extremely detailed graphics. To make it easier to understand we can offer two versions of those graphics, with the zoomed section showing when you click on the main view.</p>
<p>The example below is from <a href="https://www.edx.org/course/mit/7-00x/introduction-biology-secret-life/1014" target="_blank">7.00x: Introduction to Biology</a> and shows a subset of the biochemical reactions that cells carry out. </p>
<p>You can view the chemical structures of the molecules by clicking on them. The magnified view also lists the enzymes involved in each step.</p>
