390 Last Day Quick Answers 5 May

Most important thing today - any questions about your exam.  But, I think did most of that last time.  Are there questions different from Friday?  Any new topics? Please remember - the next week is important.  Take it seriously.   And please oh please let's not have issues about academic integrity.  You may access _NO_ materials during the exam.  If you violate this, you will fail the _course_ and be reported for an academic integrity violation.  We'll be back here in 192 hours.  Bring computers and plan your time carefully, the exam _will_ end promptly at 6p.

Yes, we've done a vast amount, please remember that you have no reason to try to put it all together into one big picture.  That's my job.  Find 4-6 focused stories that you want to talk about.  Don't feel bad that you're not talking about everything.  That's not possible and not the goal. 

Does anyone have any last questions about their papers?

I have now dropped lowest reactions for everyone (including a zero for the one before the first class if you didn't do it).  My goal is to get papers processed over the weekend and again have a more updated current average then.    Thank you to those two who earned full credit for every reaction, and the five who got to drop a nonzero score (thus completing each reaction), and the four who were perfect after drops. 


If you miss sending me reactions, then write an email.  I will reply to all, and we can continue it as long as you like.  Of course - the only reason I keep saying it is that I will miss them. 

I will be available regular office hours and Thursday 1-3p in South 336 and a special office hour finale Thursday evening at 8p in S. 336.

Arrow's theorem says that there _cannot_ be an ideal voting system for 3 or more candidates.  We must pick the failings we choose to accept.  And - we can do that.  We can pick weaker goals to satisfy.   Someone asked how this is proven.  I don't know, b
