Project Rhea for MA 375 Fall 2008 Professor Walther
Basic pointers
- In order to do any editing, you must be logged in.
- If you look under MediaWiki FAQ, you get lots of instructions on how to work with Rhea. Some important things are under item 4 in that manual.
- If you want to do things like $ \sum_{i=1}^\infty 1/i^2 = \frac{\pi^2}{6} $ in Rhea then you should look a) at the "edit" button on this page and b) get acquainted with Latex [1], a text-formatting program designed to write math stuff.
- Here is some more math, to show you mathsymbol commands:
$ \forall x\in{\mathbb R}, x^2\ge 0.\qquad \exists n\in{\mathbb N}, n^2\le 0 $ where $ {\mathbb N}=0,1,2,\ldots $
- If you want to make a new page, all you need to do is to invent one. For example, let's say I want to make a page for further instructions on how to deal with Rhea. I just type "double-left-square-bracket page with more instructions double-right-square-bracket", where of course I use the actual brackets. The effect is: I get a link (initially red_MA375Fall2008walther) to a page that is the empty set. Once I click it, the link page with more instructions_MA375Fall2008walther turns blue and I am transferred to a newborn page of name as indicated.
Note: it may take a few minutes for the new page to start existing. If you click the red link and nothing happens, wait a bit and try again.
Ideas for posting
(Question: Are these just ideas, or are they required? For example, if we do something else instead, would that count for our weekly contribution to Rhea without us having to do these? Answer::
Each of you is supposed to do something on Rhea each week. You may write what you like, where you like it. You may create new pages, or links between existing pages, or post movies or illustrations or whatever. Be inventive, go with your guts. If you want to know the answer to a question, ask for it. If you have an idea to somebody else's question, state it. If you feel lost, explain what confuses you.
Regarding "I'm awful with editing with this thing": look at other's peoples posts, this is by far the best way to figure out how to do something that you have seen elsewhere.
Regarding "Where do we put it": wherever you think it belongs. This may be on existing pages, or on a page that you create specifically for that purpose.
Main rule: don't be shy!
Eg, maybe someone could make the "Ideas for posting" a separate page so it does not take up the space on the front page...)

Week 1
For this week, click this link here and on that new page create a page as outlined above. Then move to that page and state your favorite theorem. Why is it your favorite theorem? Have other people the same favorite theorem? Crosslink! Use the math-environment if appropriate.
Week 3
For week 3: post and discuss the notion/theorem that you have found hardest to understand so far. Alternatively, find somebody else's post and reply to it by explaining how you understand things.
Further idea: discuss how quotations/citations/references should be handled on a Rhea.
