Press <return> to show content...Dr. Hentzel:

	Tuesdays are fine for us here. I'll let you take your pick between
11/6 and 11/13. Our afternoon meeting time starts at 1:00 p.m.
My class will be a "captive" audience, and of course I will invite any other
math students and faculty who wish to attend.

	If you're interested in talking to students in a more informal
setting, I will see if I can arrange a lunch time with the students.
However, students here tend to have their own agendas (besides eating) from
11:00-1:00, so I can't guarantee an audience. If you think you'd like to try
it, I will see what interest there is.

	If that all works out for you, just pick one of the dates above and
then:

	1. Give me a title for your talk (just anything so that I can
circulate it across the campus.

	2. Let me know of any special needs you have for the talk
(projection systems, computer hookups, etc.) and otherwise (dietary, etc.).

	Thanks for your timely response. I look forward to hearing from you.

Steve Bean

Yes, I would be happy to give a talk on impossibility problems in algebra.

I probably will give three examples

"triangular puzzle peg"

"Problems of Antiquity"

"Solutions by formulas"

The first example should be clear, the second pretty clear, and the

last probably much less clear.

The goal is to show "How it is possible to prove you cannot trisect the
angle."

I do not really go into the details, but I give an over view.  

     The typical student reaction when they read in the book that it is
impossible to

trisect the angle is:

     "How does he know what I can and cannot do.  Maybe the author cannot

figure out a way to do it, but I am clever.  I may discover a way to do it.

Anyway, how can he know what I can and cannot do."

My best day is Tuesday.  The next best is Thursdays except for November 8.

I could come on Monday, Wednesday, or Friday but it would involve getting a 

substitute or canceling my Abstract Algebra Course which meets from

2:00 till 3:00 MWF.
