CELESTIAL NAVIGATION:
Carver Heads Group on Fix-Crawling'
,t, * *
By MURRY FRYMER
"Fix-crawling" is the name giv-
en to a new method of celestial
air navigation developed by the
engineering research department
under the supervision of Prof.
Harry C. Carver, of the mathe-
matics department.
Prof. Carver spent two weeks
in December, 1951 testing the
new navigation procedure device
against severest weather condi-
tions at Eielson Air Force base, 26
miles from Fairbanks, Alaska.
"CELESTIAL AIR navigation is
not new," Prof. Carver said. "In
the last war we could find our
position in 20 minutes by this
means. At the rate of speed that
planes now travel, 20 minutes is
too long. In 20 minutes position
will have changed by several hun-
dreds of miles in our newer, faster
planes," he maintained. -
"The University was given
the problem of discovering a
quicker method of finding posi-
tion. We believe we have found
a solution."
The importance of "fix-crawl-
ing" in the region of the pole is
further increased . because mag-
netio disturbances in the -"' ion
render a compass almcst useless,
according to Prof. Carver.
Although radio waves are the
best way of determining position
in peace time, belligerant nations
in time of war would of necessity
have to discontinue this method,
since it would aid enemy planes
as well as allied in detecting air-
craft positions, he noted.
PROF. HARRY C. CARVER
". .. easier working at the Pole"
* * * ^* * *
TO TEST "fix-crawling" the
Alaskan Air Command asked Prof.
Carver to try the device near the
pole.
"I think it's easier to work
up there," Prof. Carver said. "I
have flown 30,000 miles testing
it, and it seems to work more
easily up there than down here,"
he said.
Prof. Carver stressed the import-
ance of air bases in the polar re-
gions.
* * *
HE EXPLAINED, "With bases
at the north pole, none of these
points are more than 3,000 miles
from one another. There are in-
numerable difficulties to overcome
in establishing a military airbase
under - arctic conditions," Prof.
Carver said.
"Fuel lines freeze in the
planes," he claimed. "Oil lines
break. There are problems of
starting the motor. No ordinary
plane motor would start under
polar temperatures," he noted.
According to Prof. Carver, one
of the most unusual hazards would,
be "ice fog." The "ice fog" is a
polar cpndition in. which particlesi
of dew in the air freeze, thereby
forming an impenetrable density.j
Lights are merely reflected back
in the pilot's face, blinding him
completely, Carver remarked.

maintained that it was "now evi-
dent that Malenkov has the lead-
ership of the party and the gov-
ernment."
* * *
"THE MAIN question, therefore,
is this: Is there a fundamental
split in the party?"
Pointing out that at present
there seem to be "many issues
of not so fundamental a nature
as those that had arisen between
Stalin and Trotsky," Prof. Neal
indicated that "the split now is
propably not so deep as it was
in the 1930's.
"The necessity for making deci-
sions in new situations such as
the recent levels in the satellites
has brought conflicting ideas into
the open. In such cases it is a mis-
take to be in the minority."
THE REMOVAL of Beria, Prof.
Neal said, could result "either in a
move toward more police oppres-
sion-since the NKVD head was
accused of having permitted for-
:ign capialist plots against the
USSR to succeed-or it could re-
sult in a lessening of police op-
pression.
Agreeing to the basic reasons
for the occurance, Prof. Henry L.
Bretton also of the political sci-
ence department said, it all points
to the fact that it is impossible to
expect a modern dictatorship to
exist under collective leadership.
"The most far-reaching conse-
quences of the episode lie in the
pasing of an era, Whether this
will be for better or for worse no
one can say, but with the removal
of Beria the position of the pow-
erful police apparatus must be
changed.
"Until now the secret police has
been considered a very privileged
group. With these developments,
their power has been seriously
threatened," he concluded.

company. He has also been ap-
pointed associate professor in the
Sc'hool of Public Health.
Dr. Mallery said the addition of
Cook will round out the institute's
program of research, education
and services.
The Institute of Industrial
Health was established in 1951 on
a grant made by General Motors
Corporation in conjunction with
the Phoenix Project.
