<h1>Re: Eileen Dover university application</h1>
<p>Dear Eileen,</p>
<p>
Thank you for your recent application to join us at the University of
Awesome's science faculty to study as part of your
<abbr title="Doctor of Philosophy">PhD</abbr> next year. I will answer
your questions one by one, in the following sections.
</p>
<h2>Starting dates</h2>
<p>
We are happy to accommodate you starting your study with us at any time,
however it would suit us better if you could start at the beginning of a
semester; the start dates for each one are as follows:
</p>
<ul>
<li>
First semester: <time datetime="2016-01-20">9 September 2016</time>
</li>
<li>
Second semester: <time datetime="2016-01-20">15 January 2017</time>
</li>
<li>Third semester: <time datetime="2016-01-20">2 May 2017</time></li>
</ul>
<p>
Please let me know if this is ok, and if so which start date you would
prefer.
</p>
<p>
You can find more information about important university dates on our
website.
</p>
<h2>Subjects of study</h2>
<p>
At the Awesome Science Faculty, we have a pretty open-minded research
facility — as long as the subjects fall somewhere in the realm of
science and technology. You seem like an intelligent, dedicated
researcher, and just the kind of person we'd like to have on our team.
Saying that, of the ideas you submitted we were most intrigued by are as
follows, in order of priority:
</p>
<ol>
<li>
Turning H<sub>2</sub>O into wine, and the health benefits of
Resveratrol (C<sub>14</sub>H<sub>12</sub>O<sub>3</sub>.)
</li>
<li>
Measuring the effect on performance of funk bassplayers at
temperatures exceeding 30°C (86°F), when the audience size
exponentially increases (effect of 3 × 10<sup>3</sup> increasing to 3
× 10<sup>4</sup>.)
</li>
<li>
<abbr title="HyperText Markup Language">HTML</abbr> and
<abbr title="Cascading Style Sheets">CSS</abbr> constructs for
representing musical scores.
</li>
</ol>
<p>
So please can you provide more information on each of these subjects,
including how long you'd expect the research to take, required staff and
other resources, and anything else you think we'd need to know? Thanks.
</p>
<h2>Exotic dance moves</h2>
<p>
Yes, you are right! As part of my post-doctorate work, I did study
exotic tribal dances. To answer your question, my favourite dances are
as follows, with definitions:
</p>
<dl>
<dt>Polynesian chicken dance</dt>
<dd>
A little known but <em>very</em> influential dance dating back as far
as 300<abbr title="before Christ">BC</abbr>, a whole village would
dance around in a circle like chickens, to encourage their livestock
to be "fruitful".
</dd>
<dt>Icelandic brownian shuffle</dt>
<dd>
Before the Icelanders developed fire as a means of getting warm, they
used to practice this dance, which involved huddling close together in
a circle on the floor, and shuffling their bodies around in
imperceptibly tiny, very rapid movements. One of my fellow students
used to say that he thought this dance inspired modern styles such as
Twerking.
</dd>
<dt>Arctic robot dance</dt>
<dd>
An interesting example of historic misinformation, English explorers
in the 1960s believed to have discovered a new dance style
characterized by "robotic", stilted movements, being practiced by
inhabitants of Northern Alaska and Canada. Later on however it was
discovered that they were just moving like this because they were
really cold.
</dd>
</dl>
