<p>The chemical editor you are using ensures that the structures you draw are correct in one very narrow sense, that they follow the rules for covalent bond formation and formal charge. However, there are many structures that follow these rules that are chemically impossible, unstable, do not exist in living systems, or are beyond the scope of this course. The editor will let you draw them because, in contrast to the rules of formal charge, these properties cannot be easily and reliably predicted from structures.</p>
<p>If you submit a structure that includes atoms that are not possible or are beyond the scope of this course, the software will warn you specifically about these parts of your structure and you will be allowed to edit your structure and re-submit. Submitting an improper structure will not count as one of your tries. In general, you should try to use only the atoms most commonly cited in this course: C, H, N, O, P, and S. If you want to learn about formal charge, you can play around with other atoms and unusual configurations and look at the structures that result.</p>

<h2>Protein BUILDER</h2>
<p>The protein builder allows you string together the building blocks of proteins, amino acids, and see how that string will form into a structure. You are presented with a goal protein shape, and your task is to try to re-create it. In the example below, the shape that you are asked to form is a simple line.&nbsp;</p>

Then, adjust the sliders to the baseline (default) setting shown below.</p><p>Baseline setting of sliders:</p><ul><li>Peak to peak voltage: \(v_\mathrm{IN}=3~\mathrm{V}\),</li><li>Frequency: \(f = 1000~\mathrm{Hz}\),</li><li>Supply voltage: \(V_\mathrm{S}=1.6~\mathrm{V}\),</li><li>Input bias voltage: \(V_\mathrm{BIAS}=2.5~\mathrm{V}\),</li><li>Pull-up resistor: \(R = 10~\mathrm{k}\Omega\),</li><li>MOSFET parameter: \(K=\frac{1~\mathrm{mA}}{\mathrm{V}^2}\),</li><li>MOSFET threshold voltage: \(V_\mathrm{T} = 1~\mathrm{V}\),</li><li>Vertical plot range: \(V_\mathrm{MAX} = 2~\mathrm{V}\).</li></ul><p>You should observe in the plot that with the baseline settings,
the amplifier produces a distorted sine wave signal for
\(v_{OUT}\). Next, go ahead and select one of the music signals as the input and
listen to each of \(v_{IN}\) and \(v_{OUT}\), and confirm for yourself that the
output sounds degraded at the chosen slider settings. You will notice
that the graph now plots the music signal waveforms. Think about the
reasons why the amplifier is producing a distorted output.</p><h2>Experiment 2: Linear regime</h2><p>We now study the amplifier's small signal
behavior. Select a sine wave as the input signal. To study the small
signal behavior, reduce the value of \(v_{IN}\) to 0.1V (peak-to-peak) by
using the \(v_{IN}\) slider. Keeping the rest of the parameters at their
baseline settings, derive an appropriate value of \(V_{BIAS}\) that will ensure
saturation region operation for the MOSFET for the 0.1V peak-to-peak swing
for \(v_{IN}\). Make sure to think about both positive and negative excursions
of the signals.</p><p>Next, use the \(V_{BIAS}\) slider to choose your computed value for \(V_{BIAS}\) and
see if the observed plot of \(v_{OUT}\) is more-or-less distortion free. If
your calculation was right, then the output will indeed be distortion free.</p><p>Next, select one of the music signals as the input and listen to each of
\(v_{IN}\) and \(v_{OUT}\), and confirm for yourself that the output sounds much
better than in Experiment 1. Also, based on sound volume, convince yourself that \(v_{OUT}\) is
an amplified version of \(v_{IN}\).</p><h2>Experiment 3: Your settings</h2><p>Now go ahead and experiment with various other settings while listening
to the music signal at \(v_{OUT}\). Observe the plots and listen to \(v_{OUT}\) as
you change, for example, the bias voltage \(V_{BIAS}\). You will notice that
the amplifier distorts the input signal when \(V_{BIAS}\) becomes too small, or
when it becomes too large. You can also experiment with various values of
\(v_{IN}\), \(R_{L}\), etc., and see how they affect the amplification and distortion.</p>

<h2>WELCOME TO ESSAYS!&nbsp;</h2>
</div>
<div>
<p>While taking a course, you may be asked to write an essay or other written response. Follow the sequence above to see how assessment tools for written answers at edX work. &nbsp;In some cases, your peers grade your answer, in another scenario, a rather sophisticated AI like tool &ldquo;reads&rdquo; and provides you feedback. In every case, working with the assessment tools is easy and can help you showcase your best thinking. &nbsp;</p>

<p>This demo course is meant to show you the workflow of the edX essay grading options, not to make you write essays. If you don't want to compose your own essay, you can try these responses:</p>
<ol>
<li>Books that are offensive should not be taken off the shelf all together, but should be put in a section made for adult readers only. This way no children would see the book anyway. If an offensive book is in a school or any other place that the readers are children for the majority than it should be ok to take that book off of the shelf. All together it should be ok to remove an offensive book from a shelf but only if the book is offencive to the wrong audience.</li>
<li>No, i do not think that books, magizines, movies and music should be removed. However, I do think that the books, magizines, movies, and music should be monitred by age. The reason why is because younger children sould not be reading , listening, or watching material that is for adults or teenagers. They way these type of things can be monitred is by the child's library card. The card could have their name, age, grade, and date of birth. If there is a certain book, magizine, movie, and music that the child want a parent has to be there with them. The parent needs to show a form of identification so that the librian knows that the parent is of age. Teenagers should also be moniterd. Event though they are almost adults. Some parents not agree with some of the material. So, if their parents does not want them reading certain things their should be stickers on their cards. Even though there are plenty of opinions about what a persons child is reading , watching, or listening to I think there should be certain ways to watch what children are reading, watching or listening to.</li>
<li>In libraries, there should not be censorship on materials considering that it's an individual's decision to read what they prefer. There is no appropriate standard on what makes a book offensive to a group, so it should be undetermined as to what makes a book offensive. In a public library, many children, who the books are censored for, are with their parents. Parents should make an independent choice on what they can allow their children to read. Letting society ban a book simply for the use of inappropriate materials is ridiculous. If an author spent time creating a story, it should be appreciated, and should not put on a list of no-nos. If a certain person doesn't like a book's reputation, all they have to do is not read it. Even in school systems, librarians are there to guide kids to read good books. If a child wants to read an inappropriate book, the librarian will most likely discourage him or her not to read it. In my experience, I wanted to read a book that my mother suggested to me, but as I went to the school library it turned out to be a censored book. Some parents believe children should be ignorant about offensive things written in books, but honestly many of the same ideas are exploited to them everyday on television and internet. So trying to shield your child from the bad things may be a great thing, but the efforts are usually failed attempts. It also never occurs to the people censoring the books, that some people can't afford to buy the books they want to read. The libraries, for some, are the main means for getting books. To conclude there is very little reason to ban a book from the shelves. Many of the books banned have important lessons that can be obtained through reading it. If a person doesn't like a book, the simplest thing to do is not to pick it up.</li>
</ol>

<h2>Self-Assessed Essay</h2>
<p>In one of the most straight-forward assessment mechanisms, you are given an opportunity to answer a question, and are then asked to assess your own performance based on an instructor-provided rubric or rule. Writing and assessing your own answers allows you to develop high levels of reflection as you revisit your answers, discovering for yourself your strengths and weaknesses in a way that will make it easier to understand how to learn. You can use the example below to see how it works.&nbsp;</p>

<h2>Combined Open-Ended Assessment</h2>
<p>All of the options for open-ended grading can be combined in order to provide multiple ways of grading the same problem. &nbsp;The combination can even require that you pass a certain level on one phase of grading before continuing on to the next phase of getting feedback.</p>
<p>The example below has combined self-assessment, machine assessment, and peer assessment.&nbsp;</p>

<h2>Find Your Study Buddy</h2>
<p>Working with other students offline can help you get the most out of an edX course and even increase the likelihood you will successfully complete the course. So, your homework is to find a study buddy.</p>
<p>The <a href="http://www.meetup.com/edX-Communities/">edX Meetup Community</a> is a fantastic way to find study buddies in your area. Meetups make it easy for students to organize get-togethers or study sessions in coffee shops and cafes, libraries, or at local schools. If there isn&rsquo;t an edX Meetup Community in your area, you can easily start one up.</p>
<p>Here are some Meetup Communities near you:<br /> <iframe src="http://www.meetup.com/edX-Communities/embeds/closest_event_list?css=&amp;w=600&amp;bg=light" height="320" width="600" title="Communities Near You"></iframe> <br /> The course specific discussion forums are also a great place to find neighbors or even new friends to invite to a Meetup you are looking to organize or even a virtual Google Hangout. Make sure you also join the edX community on <a href="https://www.facebook.com/EdxOnline">Facebook</a>, <a href="https://plus.google.com/b/108235383044095082735/108235383044095082735">Google+</a> or <a href="http://vk.com/edxrussia">Vkontakte</a> and to share with friends your edX experience. You may even inspire a friend to join edX and enroll in the course with you.</p>

<h2>Peer-Graded Essay</h2>
<p>Lastly, your course might use peer-graded essay assignments. &nbsp;One of the best ways to learn is to be exposed to other people's responses to a question that you have already thought critically about. Reading incorrect responses will make you more aware of many of the subtleties in a question that you might have otherwise taken for granted. Reading correct responses allows you to see different perspectives on the same question. &nbsp;</p>
<p>In some courses, several of these essays tools are used together to really provide a great learning experience.&nbsp;</p>
<p>How does the peer-grading tool work? &nbsp;There are three steps:</p>
<ol>
<li>Answer the question. Write a response to the prompt to the best of your ability.</li>
<li>Contributing to the student community: grade other people's responses. You will be provided with a rubric by the instructor, and asked to evaluate how other people's responses compare to the rubric. You can participate in this grading workflow by clicking on the "Open Ended Panel" option on the top of the screen, or by using the "Peer Grading" panel on this page below your submission.</li>
<li>After you have graded other student responses, your response will be included in the pool of responses to be graded, and other students will provide you with feedback on how you have done. You will see the results of the peer grading process in the same place in the courseware that you originally submitted your response.&nbsp;</li>
</ol>
<p>You can use the example embedded here to see the peer grading concept in action.&nbsp;</p>

<h2>GETTING STARTED</h2>
</div>
<p><img alt="" src="/static/getting-started_x250.png" width="250" />Welcome to the first week of the sample edX Course!

<p><img alt="Getting Started" src="/static/getting-started_x250.png" width="250" />Welcome to the first week of the sample edX Course! We created this to give you &ldquo;the basics&rdquo; of how courses work at edX. Almost all edX courses have weeks, lessons, lectures, homework assignments, and exams. This demo course has three example weeks &ndash; most courses last 4 to 12 weeks.</p>
<p>You are in Week 1, Lesson 1. Lessons typically include things like videos, readings, interactive questions, laboratories and more. &nbsp;These are presented from left to right, in&nbsp;the row of links above. At edX we call this a <em>lesson</em> or a <em>learning sequence.</em></p>
<p>Explore the lesson sequence by clicking on the icons above or the arrows below.&nbsp; We tried to make these fun, so make sure to check out each item. &nbsp;</p>

<p>The demonstrations that professors are able to put together for their edX videos can be extremely engaging and informative at the same time. Here is an example of another kind of presentation that you might encounter in a class.&nbsp;</p>

<h2>&nbsp;OVERALL GRADE PERFORMANCE</h2>
<p style="margin-top: 0px; margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">The progress tab (selectable near the top of each page in your course) shows your performance. Click on it now, and you will see how you're doing in this demo course.</p>
<p style="margin-top: 0px; margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">The bar chart shows the overall percentage that you have earned on each assignment in the course, and how each of those assignments combine into your overall grade. Further down the page is a detailed breakdown of your score on every graded question in the class.&nbsp;</p>
<p><img alt="" src="/static/ProgressPage.png" /></p>

<p style="margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">You might notice that some of your assignments on the bar chart show an 'x'. The 'x's indicate the assignments that the edX system will NOT be counting toward your final grade, according to the course grading. The 'x's go to the assignments that you scored the lowest on. &nbsp;</p>
<p style="margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">Each course has its own percentage cutoff for a Certificate of Mastery. You can see where those cutoffs are by looking at the vertical description. In this demo, a "pass" is considered 60%. When you "pass" a live edX course, you will receive a certificate after the class has closed. Sorry - the demo course does not grant certificates!</p>

The edX system will only count your most recent answer towards your final grade, so if your extra experiments leave your answer in an incorrect state, then you will not get credit for the problem. </p>

by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

* js_channel is a very lightweight abstraction on top of
* postMessage which defines message formats and semantics
* to support interactions more rich than just message passing
* js_channel supports:
* + query/response - traditional rpc
* + query/update/response - incremental async return of results
* to a query
* + notifications - fire and forget
* + error handling
*
* js_channel is based heavily on json-rpc, but is focused at the
* problem of inter-iframe RPC.
*
* Message types:
* There are 5 types of messages that can flow over this channel,
* and you may determine what type of message an object is by
* examining its parameters:
* 1. Requests
* + integer id
* + string method
* + (optional) any params
* 2. Callback Invocations (or just "Callbacks")
* + integer id
* + string callback
* + (optional) params
* 3. Error Responses (or just "Errors)
* + integer id
* + string error
* + (optional) string message
* 4. Responses
* + integer id
* + (optional) any result
* 5. Notifications
* + string method
* + (optional) any params

"GREGORY NAGY: In hour zero, where I try to introduce Homeric poetry to",
"people who may never have been exposed to the Iliad and the Odyssey even in",
"translation, my idea was to get a sense of the medium, which is not a",
"readable medium because Homeric poetry, in its historical context, was",
"meant to be heard, not read.",
"And there are various ways of describing it-- call it oral poetry or",
"call it a very specialized kind of oral poetry.",
"But the important thing is that we, as modern readers, just",
"don&#39;t get the medium.",
"And so I thought before we get into hours 1 through 24, it would be",
"important to do some kind of big, grand cover everything introduction.",
"But at the same time, in this introduction, I wanted to get people",
"already interested in my technique of using close readings of very specific",
"parts of the text in order to get an idea of the overall",
"meaning of the text.",
"And so I chose eight such texts, and they&#39;re all very famous, well, some",
"more famous than others.",
"And as with the 24 hours, I number these sample texts by",
"letters of the alphabet.",
"So its texts A through H.",
"What I&#39;d like to do is just go over those passages or text and go through",
"them; try to do close readings; try to exemplify the principle of having to",
"read out of the text, not into the text; and also try to say why I picked",
"the passages that I picked.",
"And in this case my dialogic partners were Jeff Emanuel and Claudia Filos",
"who are former students.",
"They took former versions of the project that we&#39;re engaged with here.",
"And as very perceptive fellow learners, they really got the hang of",
"how to ask very incisive questions that go to the core of what this whole",
"project is all about like what&#39;s at stake in the Iliad?",
"What&#39;s at stake for the number one hero?",
"But what&#39;s at stake for some very secondary, bit player hero, as well?",
"How does Achilles see himself as the prototype for the ultimate heroic",
"experiment--",
"which is the way I look at the Iliad--",
"and how is he self-conscious about it?",
"CLAUDIA FILOS: So, Greg, can you talk a bit about why you chose these",
"particular eight passages as the focus passages four hour zero?",
"GREGORY NAGY: Well, here I was trying to introduce all of Homeric poetry to",
"people who may not ever have read the Iliad and the Odyssey.",
"So I thought how can I talk about the Iliad and the Odyssey and show some",
"very representative pieces of text?",
"And sometimes, I call them passages.",
"Sometimes, I call them texts.",
"When I number them, I call them text.",
"And all eight of these that I have selected are what in popular culture",
"would be parts of the greatest hits, so to speak, of the Iliad and Odyssey.",
"So, for example, if you look at text A on this introduction to Homeric poetry",
"which I call appropriately hour zero, there it is--",
"the first few verses of the Iliad.",
"In fact, the first 10 verses.",
"So Iliad scroll one, verses 1 through 10.",
"SPEAKER: Anger, goddess, sing it of Achilles, son of Peleus.",
"Disastrous anger that made countless pains for the Achaeans and many",
"steadfast lives it drove down to Hades, heroes&#39; lives.",
"But their bodies, it made prizes for the dogs and for all birds.",
"And the will of Zeus was reaching its fulfillment.",
"Sing starting from the point where the two, I see it now, first had a falling",
"out, engaging in strife.",
"I mean--",
"Agamemnon, the son of Atreus, lord of men, and radiant Achilles.",
"So, which one of the gods was it who impelled the two to fight with each",
"other in strife?",
"It was Apollo, the son of Leda and of Zeus.",
"For he, infuriated at the king, Agamemnon, caused an evil disease to",
"rise throughout the mass of warriors, and the people were getting destroyed.",
"GREGORY NAGY: I tried to replicate in my translation the fact that the very",
"first word of the Iliad is menis, which means anger, a special kind of",
"anger, a cosmic anger.",
"We&#39;ll talk more about that.",
"That man, tell me, oh muse, the song of that man.",
"That versatile man who, in very many ways, veered from his path and",
"wandered off far and wide after he had destroyed the sacred citadel of Troy.",
"Many different cities of many different people did he see, getting",
"to know different ways of thinking.",
"Many were the pains he suffered in his heart while crossing the sea,",
"struggling to merit the saving of his own life and his own homecoming, as",
"well as the homecoming of his comrades.",
"But do it he might, he could not save his comrades even though he",
"very much wanted to.",
"For they perished through their own deeds of sheer recklessness,",
"disconnected as they were because of what they did to the cattle of the sun",
"god Helios--",
"they ate them.",
"So the god deprived them of their day of homecoming.",
"Starting from any single point of departure, oh goddess, daughter of",
"Zeus, tell me as you&#39;ve told those who came before me.",
"GREGORY NAGY: And then if we go to text B, look at that.",
"The first quote unquote word is man.",
"All right, in English, we have to say the man, but in the original Greek,",
"andra, the man.",
"And that&#39;s the subject of that epic.",
"Just as the subject of the Iliad is the anger of Achilles, the subject the",
"Odyssey is the man who is Odyssey.",
"So there you are.",
"That&#39;s why I shall zone text B to be the first few verses of the Odyssey.",
"And in fact just as with the Iliad, it&#39;s the first 10 verses.",
"Nice and symmetrical.",
"CLAUDIA FILOS: so those first words are so key.",
"The epics are telling us right away.",
"GREGORY NAGY: These epics are-- both of them, Iliad and the Odyssey--",
"telling what the subject is with the first word.",
"In the case of the Iliad, first word of 15,000 plus verses.",
"In the case of the Odyssey, the first word of 12,000 plus verses.",
"Pretty good.",
"SPEAKER: And now, tell me, oh muses, who live in your Olympian abodes,",
"since you are goddesses, and you were there, and you know everything.",
"But we only hear the kleos and we hear nothing.",
"Who are the princes of the Danaans?",
"GREGORY NAGY: Now look at text C for hour zero.",
"This is where Hector says there&#39;ll be a memory of the time that my fire",
"nearly destroyed not just the Achaeans but the entirety of Greek",
"civilization.",
"You see, if the fire of Hector had reached the ships of the Achaeans that",
"were beached like sitting ducks on the Hellespont, then, essentially, there",
"would be no more Greeks.",
"And so Hector, this character, is very aware of it-- says let there be a",
"memory of the time when this was about to happen.",
"And so poetic how the fire will confound the key Achaeans who the",
"Argives, who are the Danaans, by the smoke.",
"CLAUDIA FILOS: choosing it, you&#39;re saying there&#39;s something very",
"important about memory for both.",
"GREGORY NAGY: It&#39;s all important because this isn&#39;t just memory, this",
"is poetic memory.",
"And as we&#39;ll see when we get to hour two, it&#39;s a kind of total recall, if I",
"may use science fiction term.",
"SPEAKER: Ah, me, the pitiful one.",
"Ah, me, the mother, so sad it is of the very best.",
"I gave birth to a faultless and strong son, the very best of heroes, and he",
"shot up equal to a seedling.",
"I nurtured him like a shoot in the choicest spot of the orchard only to",
"send him off on curved ships to Troy to fight Trojan men.",
"And I will never be welcoming him back home as a returning warrior, back to",
"the house of Peleus.",
"GREGORY NAGY: Let&#39;s go to text D of hour zero, which is where Thetas, the",
"mother of Achilles, is speaking.",
"And she&#39;s not just speaking, in terms of the medium, she&#39;s actually singing",
"a song of lament, and we&#39;ll talk a lot more about lament later.",
"But I love the fact that as she is lamenting Achilles, who&#39;s not even",
"dead yet, she is comparing him to a tender, young shoot or seedling.",
"And I&#39;m pretty deliberate on why I use not just the translation seedling but",
"also shoot for imagining the hero as a beautiful, young planet.",
"OK, so there it is.",
"And even the specifics of the language that she uses, Thetas uses, in her",
"song of lament for Achilles, who&#39;s not even dead yet--",
"some of the specific language like [INAUDIBLE]",
"which I translated as he shot up.",
"It&#39;s a kind of violent, vegetal activity that you would associate with",
"mutant phenomena, not necessarily natural phenomena.",
"Sure, a growing planet is natural but this is an unnatural growth.",
"It&#39;s just so much quicker and so much more vibrant.",
"CLAUDIA FILOS: going to be thinking about what&#39;s",
"natural and what&#39;s unnatural?",
"GREGORY NAGY: Very much so.",
"I try never to use the word supernatural.",
"I&#39;ll try to use a superhuman because even the superhuman realm can still be",
"a function of nature.",
"JEFF EMANUEL: This an example maybe of what we&#39;re going to be thinking in",
"extremes as well.",
"GREGORY NAGY: Very much extremes.",
"And as we&#39;ll see it in our working definition of the",
"hero, the hero is extreme.",
"That&#39;s definitely one of the major characteristics.",
"When we talk about the growth spurt of Achilles, I&#39;m tempted to say that it&#39;s",
"an unnatural growth spurt.",
"But what I&#39;m really trying to say-- it&#39;s part of nature, but it&#39;s",
"exaggerated, extreme, as Jeff said.",
"We&#39;ll get back to that, but I wanted to expose people as soon as possible",
"to the idea that a hero is the subject of lament, And lament will be a very",
"important part of our agenda."

"GREGORY NAGY: In hour zero, where I try to introduce Homeric poetry to",
"people who may never have been exposed to the Iliad and the Odyssey even in",
"translation, my idea was to get a sense of the medium, which is not a",
"readable medium because Homeric poetry, in its historical context, was",
"meant to be heard, not read.",
"And there are various ways of describing it-- call it oral poetry or",
"call it a very specialized kind of oral poetry.",
"But the important thing is that we, as modern readers, just",
"don&#39;t get the medium.",
"And so I thought before we get into hours 1 through 24, it would be",
"important to do some kind of big, grand cover everything introduction.",
"But at the same time, in this introduction, I wanted to get people",
"already interested in my technique of using close readings of very specific",
"parts of the text in order to get an idea of the overall",

"And so I chose eight such texts, and they&#39;re all very famous, well, some",

"And in this case my dialogic partners were Jeff Emanuel and Claudia Filos",
"who are former students.",
"They took former versions of the project that we&#39;re engaged with here.",
"And as very perceptive fellow learners, they really got the hang of",

"project is all about like what&#39;s at stake in the Iliad?",

"experiment--",
"which is the way I look at the Iliad--",
"and how is he self-conscious about it?",
"CLAUDIA FILOS: So, Greg, can you talk a bit about why you chose these",
"particular eight passages as the focus passages four hour zero?",
"GREGORY NAGY: Well, here I was trying to introduce all of Homeric poetry to",
"people who may not ever have read the Iliad and the Odyssey.",
"So I thought how can I talk about the Iliad and the Odyssey and show some",
"very representative pieces of text?",
"And sometimes, I call them passages.",
"Sometimes, I call them texts.",
"When I number them, I call them text.",
"And all eight of these that I have selected are what in popular culture",
"would be parts of the greatest hits, so to speak, of the Iliad and Odyssey.",
"So, for example, if you look at text A on this introduction to Homeric poetry",
"which I call appropriately hour zero, there it is--",
"the first few verses of the Iliad.",
"In fact, the first 10 verses.",
"So Iliad scroll one, verses 1 through 10.",

"a song of lament, and we&#39;ll talk a lot more about lament later.",
"But I love the fact that as she is lamenting Achilles, who&#39;s not even",
"dead yet, she is comparing him to a tender, young shoot or seedling.",
"And I&#39;m pretty deliberate on why I use not just the translation seedling but",
"also shoot for imagining the hero as a beautiful, young planet.",

<h1>Syllabus</h1>
<p>Many courses include a syllabus tab that includes an overview of the course and what is expected of you.&nbsp;</p>
<p>This demonstration course shows examples of everything that instructors might include in an edX course, and an explanation of how to interact with those components. The demo course does not distribute a certificate, although the grading system is active so that you can see how the grading system works.&nbsp;</p>
<p>Like most courses on edX, the courseware is organized into a schedule, which you can see when you access the course material. In this case, that schedule is only there in order to illustrate how normal classes are organized. It is NOT expected that you take an entire week to go through "Week 1" of this demo course.&nbsp;The illustration schedule is roughly ordered by how often you might come across aspects of the edX platform.&nbsp;</p>
<p>This syllabus allows you to access the course material by topic, in case you are looking for something specific on how to use the edX platform.&nbsp;If you just want a basic description of how to take a course on edX, start by clicking on 'the basics', below.</p>
