1. Why not have the conference in 1981?  This would give plenty of
time to prepare.  1980 is ok, but delaying might get better papers.

2. I suppose the AI Lab could pay postage, etc.  What larger sums of
money do you have in mind.

3. Assuming equal physical facilities, having the conference at Stanford
presents no large advantages over Santa Clara, unless the fact that
conferences are an industry at Stanford helps.  It might also generate
excessive greed on Stanford's part.  Assuming an adequate conference
committee, there won't be a prestige difference.

4. I bet he won't take an active part, but you should solicit Bruce
Buchanan's advice.  He was IJCAI program chairman.

5. Certainly Friedman should be invited.  He is very energetic.  The
conference could even be held at Indiana, although there is less incentive
to go there.

6. Proving the correctness of LISP programs should be a major topic.
You could invite either Carolyn Talcott, Bob Boyer, J. Moore or Corky
Cartwright to be on the program committee.  This topic should include
both automatic proof as done by Boyer-Moore and the mathematics of LISP
as done by Cartwright and me.  Inclusion of this topic will put LISP
one up on APL and other languages where this is not yet a consideration.

7. It occurs to me that IJCAI could afford to lend the conference money,
but I don't know who could make such a decision.  Bruce would know.  For
that it would be best to leave out the words about non-AI contributions.

8. If you take non-AI contributions seriously, then the biggest are to
REDUCE and MACSYMA.  Hearn and Moses (Fateman at UCB locally) are obvious.

I have seen Altos and would prefer high quality displays.  I have
unrestricted money that will buy a high quality Baskett display for
JMC as soon as they are available.  However, I think the Department
can and should cover the Department with displays of at least
Datadisc quality.  If the Department can afford better quality, that's
fine, but I doubt that we should settle for less than full coverage
in order to get high quality.  My guess is that if a person had a choice
between a Datadisc on his desk and an Alto in a terminal room, he would
choose the former.  Should a poll of faculty and students show that
a reasonable number of people would prefer high quality in terminal rooms,
I would certainly go along.  What I fear is that the Department will
divide into 1st class citizens with high quality personal displays,
1.3 class citizens with Datadiscs 2.8 class citizens with access to
terminal rooms.

I am willing to wait a "week or two", pointing out that we have been
waiting a year or two.  I will be leaving for two weeks on October 14.
Could we set a definite date to happen before then?

CASBS stands for Center for Advanced Study in the Behavioral Science.
Its location may be on your Stanford map.  Anyway you can easily find
it as follows:  Go out of the campus on Mayfield to the north
and continue north on Junipero Serra.  You will see a road on the
left with a sign saying Stanford Golf Course, CASBS and National
Bureau of Economic Research.  Turn left there and immediately
left again and up to the top of the hill.  If you go on Junipero
Serra farther north, you will immediately see a bridge across
the road.  This means you have gone too far.  The
distance is probably not too far for Prof. Tang to walk
if he doesn't have a ride, but if he phones me at
321-2052 around 1:30, I'll get him a ride or comae after him.

Many thanks for your suggestion.  As is, it isn't what I want, because
introducing the f is conditional on first proving that there is a unique
y.  However, tinkering with it led to an even simpler solution to
my problem.  Given any wff P(x,y) with x and y free and a previously
unused function symbol f, I can write (∀x)((∃y)P(x,y) ⊃ P(x,f(x))) as
a kind of partial definition of f and be guaranteed against contradiction.
For any values of x for which I can prove (∃!y)P(x,y), f(x) will be
determined.

In case the terminal on which you read this doesn't have logical symbols,
the formulas are (for all x)((there exists y)P(x,y) implies P(x,f(x)))
and (there is a unique y)P(x,y).

You are probably saying, "had I known that was all he wanted ...".

I don't agree with the statement.  Besides money it took the conviction
of the American physics community that this was the most important thing
to work on.  If the country's smartest people were dedicated 
personally to connecting to human sensory and motor organs, it
might be done in a few years with only modest increases in funding.
I guess connecting to human sensory and motor neurons in a simple
way is a straightforward problem that could be solved in  a fixed
time by dedicated effort.  Other robotics problems, such as the
ability to skin a cat, require conceptual advances that may be
as hard as the theory of the nucleus as developed between
Rutherford's work early in the century and the discovery of
fission in 1939.

Anything that would optimize the probability and speed of
getting mail between two different computers would be of
greater import.
Right now we have the pessimal compromise: the server accepts the
mail, and the mail program deletes it without a trace!

I vaguely remember the slides, i.e. transparencies.  I have made several
attempts to keep files of transparencies for various lectures, and
there are some.  I don't remember these specifically.

I will be away until approximately September 1.  I will be in
Edinburgh until July 15 and then at Thomas J. Watson Research Center,
Yorktown Heights N.Y. except for one week at IJCAI.  I will read net
mail.  Patte will know about details.

9. You should also talk to Les about practical matters.
