put emphasis on a carefully or-
ganized structure to make sure
that students have the basic ideas
with which to work, he said.
Prof. Gagne listed four basic
research conclusions on thinking:
1) People tend to get into ruts
in their thinking;;
2) Thinking is greatly influenc-'
ed by what is said to the thinker;
3) Errors in thinking are not
usually errors in logic. In most-
cases the cause is distraction; and
4) "Successful" thinking is def-.
initely related to the number of.
ideas one has.
"We need to know more about
thinking conditions, such as nev-
vous system growth, learning pre-
conditioning and the immediate
communication -needed for think-
ing," Prof. Gagne said.
Five Stages
He divided problem solving-
directed thinking-into the stages-
of problem definition, concept for-
mation, determination of courses
of action, decision-making and
verification of that decision.
Successful problem solving is
not a matter of practicing a single
form of behavior, such as inven-
tiveness. or creativity. Also, stu-
dents cannot be made to solve
problems successfully by exhorting
them to be creative or inventive,
-Prof. Gagne concluded.
His talk was part of a series
on teaching and learning in the
field of medicine. The series is
sponsored by the Center for Re-
search on Learning and Teaching.

little frustrated because he and
his colleagues have been trying
since before the MIT experiment
to shoot a laser off the moon with
the University's 36-inch telescope.
Typical Ann Arbor weather pre-
vented such a "first" from being
accomplished. Some MIT officials
were irked that they had not been
told about the "stunt" beforehand
-it was a well kept secret among
those working on the experiment.
} "Of course,.it was just a stunt,"
Prof. Franken says. "But it catch-
es the public eye and gets in some
national magazine. It could do
more. for getting money for re-
search, for instance, from a legis-
lature, than some speeches."
Not Much Chance
Right now, Prof. Franken
doesn't see much of a chance of
ever getting a moon bounce done
here. He is at Yale University
now, on a sabbatical from his work
at the University, but if the equip-
-meat is set up and the weather is
good this spring, he will return to
the campus immediately to see if
his group can do what they have
trot been able to do for almost a
"We had six men working hard
to set the thing up last spring,
but the weather was always too
bad to conduct the experiment. Al-
so, our telescope scatters too much
light. It's a fine telescope, but it's
50 years old," he says.
Bouncing a laser beam off the
moon is like shooting a stream of
water at a target a quarter of a
million miles hway and hoping to
catch some of the drops as they
spray back.
Drop Diversity
With the sensitive instruments
existing today, those precious
"drops" can be caught, but they
have to be distinguished from
other "drops" that may not be a
part of the experiment but still
occlude the results.
Many conditions must be met to
catch the "drops" of light. The
moon must be in the right posi-
tion, a little less than half-illum-
inated, and the weather must be
clear all the way through tne at-
mosphere-not just near the sur-
face of the earth.'
The mirror of the telescope. is
the light gathering surface that
must be of a good enough quality
to capture the few photons that
return from the moon, and an ex-
tremely sensitive photocell elec-
tronically counts these photons.
Single Frequency
The heart of the entire opera-f
tion, the laser, sends out its light
at a single, sharp frequency The
most commonly used laser is made
of a ruby crystal. The wave length
of the' i lit eitted is singular
for, .the. ruby crystal-6,934 Ang-
This is at.die far end of the vis-
ible light spectrum, near the infra-
red. As the light passes through
the .atmosphere, it loses 10 per
cent of its power in both directions.
The light spreads about five in-
ches for every mile it travels,
reaching the. moon with a beam
radius of only 20 miles. For any
type of light, this is a very small
spread for such a great distance.
MIT scientists aimed their laser
to get maximum reflection from
the moon. A new moon or a moon
reflecting no sunlight back to the
earth cannot be used because it is
high enough in the sky only at
times when the sunlight would in-
terfere with the experiment.
Between Phases
So a compromise is taken be-
tween the moon's new and full
When the light returns to the
earth, filters remove all wave
lengths around 6,934 Angstroms
that would interfere with the pho-
tocell as it counts the returning
ph o t ons. Otherwise, ordinary
moonlight and light in the earth's
atmosphere would obscure the
photocell's operation.
MIT scientists "shot" the 13
separate spurts of light a minute]

apart to allow the laser to cool off
between "shots." They said that
they detected the returning pho-
tons-about 12 each time.
Members of the group that have
been working on the University's
moon bounce experiment with
Prof. Franken are Prof. Dean B.
McLaughlin of the astronomy de-
partment, Prof. Murray Miller of
the electrical engineering depart-
ment, Wes Vivian and Lee Evans
of a local engineering firm that
has supported the project, and

Prof. Joy explained the "thou-
sands of details" to be taken care
of in any catastrophe that would
hinder the effective working of
any program.
The University, with one-sixth
the total resources of the city of
Detroit and more than twice those
of the rest of Washtenaw Couty,
has taken only a "tentative ap-
proach to the problem" with no
strategic or policy assumptions,
Ostafin said. It does not believe
in civil defense exercises, or site-
ilar preparations and is relying on
students "to behave in a mature
and ingenious manner" he added.
Solari pointed out that any civil
defense program has the tendency
to make people feel safer and as
a result more antagonistic to the
problem of international relations.
However, they explained the report
as devoid of any moral or ethical
justification and merely as an an.-
alysis of the problem facing the
The report points out that the
steam tunnel system, previously
believed to be an ideal means of
communication and transportation
between shelter areas, has inade-
quate ventilation and is poorly
identified. In addition, any rup-
ture of steam pipes in any tunnel
area would immediately make the
areas unlivable.
The question of whether or not
the University should join the pro-
gram of the federal government,
whereby some monetary assistance
is exchanged for making its shel-
ters open to the public at large,

tion w i t h o u t recommendation
