to me your l1étter of 6 October 1959 for reply. It is Miss ——-> > .
contention that you have misunderstood her letter to you of 25 September
1959, and upon an evaluation of both pieces of correspondence, I a
forced to concur with her point of view. Way I note the dise: iS

as I see them, to follow:

l. Wiss qgge requested most specifically information concerning
"two local recent happenings." Your reply refers to the
phenomena as sightings, which of course they were not.

2. You have sent to Miss GP: eral lengthy forms to complete;
these forms deal entirely with Infonnsti oa to be supplied by
a witness to some phe f

henomenon. Since Miss Wer did not herse
witness the phenomena referred to by her, she cannot, of cours
complete the forms, and I am somewhat amazed that you inferred
that she did so.

If you are not in communication with the Wrisht-Patterson Air
Force Base which all egedly commented upon the phenomena, would
you suggest that we write to the base ourselves? I say this

I!

because you have written that the reports "contained insufficient
data for valid conclusions." iliss ie did not ask, you will
note, for conclusions, but rather requested "any details you might
be at liberty to supply us."

Please do not feel that I am being critical simply because I enjoy
the process; however, I cannot help but feel that large organizations
with much work to do, such as your own, sometimes overlook important
Getails in cenling with volume. J reszret the necessity of usinf more
of your time in this matter as much as I regret having to use my own.
thank you for your continuing patience and codperation.

Four Planets Now Visibdie

With four of the five planets that can be seen without
a telescope visible during June, this month promises an unusual

display of naked-eye planets.

By JAMES STOKLEY

THE BEST DISPLAY of naked eye planets
for @ conmsideraife tength of time is Vist
ble on June evenings. Venus, Mars, Jupiter
antl Sateen, all that are ever visible with
out it telescope, except for Mercury, can
now be seen at the same time. (Mercury
is too nearly in the same direction as the
sun to be seen.)

All these plancts, as well as the brighter
stars, are shown on the accompanying maps
as they appear about ten pin., your own
kind of standard time (add one hour for
daylight saviag time) at the first of June,
and an hour earlier ut the middle of the
month (when the sky is actually not very
dark).

Long before any other planet or star ap-
pears, Venus can be secn in the west. Its
magnitude is now minus 3.9 on the astron-
omer’s brighmess scale, and it stands in the
constellatien of Cancer, the crab. On June
{5 Venus will be 1 ‘500,000 niles from
earth.

Mors Close to Venus

Close to Venus, when the sky gets
cutker, you will see Mars. At a distance
of 205,400,000 miles, on the Loh, it is only
abouts hundredth as bri ight as Venus. On
lune I Venus will be well below Mars; both
are moving toward the east and Venus passes
Mars on the morning of June I4. They
will be invisible in the United Stutes ut
the time of closest approach, but on the
preceding and Slowing evenings they will
appear unusually near each other.

Jupiter is the second Srightest planet. It
is in the south im Libra, the scales, at a
distance of 415,000,000 calles. , But even
though it is so far, its mognitade is minus
two, which makes ir a [ce more than a
sixth as bright as Verus.

The fourth planet, Secor. ts low in the
smutheast, in Sagittarius, the archer: its
distance is $43,000,000 miles. Ta ragaitude
it is plus 6.3, equal to a bright first magni-
tude star. H.: awever, its low altitude makes
Saturn appear fainter, because of absorption
of its light by the carth’s atmosphere.

Among the stars which, unlike the
planets, shine with their own light, the
brightest is Vega in Lyra, the lyre, high in
the east. Below this group is Cygnus, the
swan, swith first magnitude Deneb. Like
Satura, this is somewhat dimmed because
ir is rather low in the sky. To the right is
AMhioir, in Aquila, the eagle.

Hish in the south is Arcturus, in Bootes,

the bearahiver, Below it is Virgo, the
virgin, with Spica. To the right of this

group you will tind Leo, the lion, of which

Regrlus is the brightest star, Law te dy
southeast, to the left of Libra. is the seor-
pion, Scorpius, with first magnitude An
tures, another star that is dimmed by its
low altitude.

Even more dimmed are two stars shown
low in the northwest; Pollux, in Gemini,
the twins, and Capella, in Auriga, the
charioteer. Both were very prominent in
the winter evening sky, but the stars are
now about to disappear for a “summer
Vacation.”

On Sunday, June 21, at 10.50 p.m. EST
(9:50 pim., CST; 8:50 pm. MST; 7:50
pan. PST; add one hour to each for corre-
sponding DST) the sun reaches its farthest
north position for the year, when it will be
over the Tropic of Cancer, Actually, at
that moment, it will be directly over a
point in the Pacific Ocean, off the island of
Formosa, This is the time of the summer
solstice, which marks the beginning of
summer in the Northern Hemisphere. In
the Southern Hemisphere, it is the begin-
ning of winter.

With four planets visible in June in the
evening sky, and the carth, as always, visi-
ble at our feet, we can see a considerable
part of the solar system.

modern one is displayed in New York City
at the Hayden Planetarium, with balls
representing the planets revolvingg on tracks
around a glowing sun,

But any such model gives the idea that
the solac systern is much more crowded
with planets than it actually is. Hf you make
the ball representing the sun of reasonable
size, the planets are microscopic. and spread
over au ares too large for convenience.

Washington, D.C., might be a gowd place
for such a model, and the dome of the
Capitol might represent the sun. The out
side diameter of the dome is slightly over
135 feet. Where, then, would the planets
be placed, and how | large would the balls
representing them have io be?

For Mercury a ball about 54% inches
in diameter would be necded, and it should
be placed slightly more than a mile away
from the sun. This could put it inside the
Department of Justice building at 9th Street
and Pennsylvania Avenue. Venus, the next

EDUCATION
Engineer Enrollment
Drops First Time in Years

IN THE face of the aosition's greatest
nea! for trained engineers und scientists,
freshinan engineering enrollment declined
tackedly in 1958 for first time in eight
Yours,

Furthermore, one in five engineering
schools expects a further drop in freshman
enrollment next fall.

Last year, 70,029 engineering freshmen
enrolled in the nation's schools compared
with 78,757 in 1957. This was a drop of
HWAI%. Toral college freshmen enrollment

the
Vee

sor
in 1958, however, was up seven percent
over the previous year.

These facts were contained in a report
made public by the Engineers Joint Coun-
cil, covering 223 institutions in the United
States granting degrees in enginecring.

Tieads of engineering schools said appli-
cations from qualified students have fallen
for these three reasons:

1. A false appraisal of the long-range
engineering career opportunities by coun-
selors, aks and parents, based on re-
ports in the general press on lay-offs during
the 1957-58 recession.

2. Increased concern about the rigors of
engineering curriculum.

3. Increased interest by potential engineer-
inge students in other scientific fields.

Engineers Joint Council is a national fed.
cration of 20 major engineering socicties
representing 300,090 of the country’s engi-
neers.

BACTERIOLOGY
New Deadly Diseases
Made From Tiny Molds

THE TINY mold that causes “athlete's
foot” has been turned into a new deadly
disease.

Deliberately designing new
tnolds may now be possid'
reported to scientists
Americana Bacteriologists
Louis, Mo.

Usually molds that cause athlete's foot
will grow only on the skin. If one of these
molds is injected into an animal's body, it
will not cause disease even though huge
sinounts are given. Now, however, there
is evidence the relatively harmless molds
ein be changed into deadly forts, Dr.
George HL. Scherer of the University of Mie
nots College of Medicine said.

Yheee different molds were placed in
small cellophane bags which were then sur-
yically tuplanted into the body cavities of
rabbits. “Vhe molds could not escape, but
nutrients could enter, keeping the molds
vive. In cach case, the mold gradaslly

cs

Science News Lerren for May 23, 1959

began to change its shape, De. Scherr said,
and in approximately 20 days “had assumed
« form and character completely different
front the one placed in the cellophane bag.”

When cach new mold was injected into
rabbits and mice, a severe infection resulted
which destroved the aninials’ intecnal
organs. If the disease was transferred from
animal to animal, it became progressively
worse. No way is now known to combat
the new disease, Dr. Scherr explained,

The disease caused by the changed molds
may be regarded as different from any
disease known, he said,

The study may contribute to knowledge
of how some bacteria suddenly can infect
man and aninals.

John W. Rippon, one of Dr. Scherr’s
students, worked with him in the study.

GENERAL SCIENCE
Oppenheimer Urges End
Cf Arms as Arbiters

THE ABILITY of the inherited institu
tions of our civilization to make proper
decisions on uses of the unprecedented new
instruments of warfare, like atomic energy,
was called in question by Dr. Robert Oppen-
heimer, atomic energy pioneer and director
of the Institute for Advanced Study, Prince-
ton, N. J., in opening a symposium in New
York on basic rescarch.,

Arms must not continue to be the hist
arbiter of disputes, he said.

“If we do not treasure the great inheri-
tanee on which all our work and life are
based, and understand the radical novelty
and the gravity of the situation in which
we find ourselves,” he warned, “there will
be few of our children to ask again of
the need for new knowledge.”

Dr. Oppenheimer and other speakers
urged the need of continued basic research,
or inquiry directed not primarily to a prac-
tical result but to the obtaining of new
knowledge.

Noe laboratory should be so directed to
its practical missions that it cannot afford
perhaps a sixth or a fifth of work that is
on the face of it unrelated to its purposes,
Dr. Oppenheimer said.

The great lesson of the past atomic dec-
aties has been, he observed from his direc
tion of atomic bomb research, that men of
science who have spent thetr whole lives
in the quest of new knowledge may be
among the most gifted practitioners of
technology.

Dr. Alan T. Waterman, director of the
National Science Faundation, Washington,
declared that for continued growth in sct-
entific research and technology and for
realization of the full potential in basic
research, there must be widespread public
recogmition and appreciation of the impor
tance of intellectual aud scholely activity.

Dr. W. ©. Baker, vice president, Bell
Telephone Laboratories, advocated tronsfer-
ence to practice in mathematical reasoning
a feaction of the tine given to learning of
physical skills which are of diminishing
inportunce,

ROCKETS AND MISSILES
Returned Space Capsule
Given to Smithsonian

THE FIRST instrumented capsule recov
ered intact from outer space after returning
to the carth’s surface at free-falling speed
was presetied to the Smithsonian Tosti.
tion on May 15.

Officials of the U. S. Air Force said the
“Data-Sphere,” which is 18 inches in diam.
eter, was launched on June 13, 1958, from
Cape Canaveral, Fla. It rose more than
200 miles, reentered the carth’s atinosphere
ut a speed of more than 10,000 miles an
hour and was ejected from the nose cone
of its rocket without parachute or other re
turding device.

After falling freely, the capsule struck the
South Atlantic with an impact 40,060 tines
greater than the force of gravity. The
sphere presented to the Smithsonian is the
first of a series of such capsules recovered
from ‘Thor and Atlas missile firings. Each
is equipped with a tiny tape recorder, a bat-
tery power-pack, dye marker, and a “bemb"
that sends out a sound to indicate its loca-
tion for recovery purposes.

Data recorded include temperatures, pres.
sures, stresses Curing take-off and climb,
conditions ar the greatest altitude attained,
heat encountered during re-entry into the
atmosphere, and the tremendous forces of
final impact as the capsule slammed into the
water.

As presented to the Smithsonian, the
sphere has all its original instruments in-
stalled, still surrounded by the foamlike
mass that kept them from shifting inside
ithe plastic capsule. The sphere’s upper half
is yellow to make it more visible, and the
bottom half is coated with a greenish-black
fish-repellent chemical.

ASTRONOMY
Rediscovered Comet May
Give Fall Meteor Dispiay

A COMET expected to give a good dis-
play of meteors this fall has been rediscov-
cred by Elizabeth Roemer of the U. 5S.
Naval Observatory in Flagstaff, Ariz.

Although it is now much too faint to be
seen without a very large telescope, the
comet will brighten sufficiently by late
October to be visible with binoculars or a
stnall telescope. Known as Comet Giacobini-
Zinner, the object is remarkable for the
showers of meteors it produced in 1933 and
1946,

The comet wilh be within about 20,000,000
iniles of the corth on Noy. 7, and the
meteor display is expected about the same
Lite,

News of the comet's rediscovery when it
is only a faiat magnitude 20 was reported
to ustronomers in the Western Hemisphere
by Dlarvard College Observatory, Cam-
bridge, Mass.

Its diameter is Il feet, 2 inches. Uranus,
about 4 feet 7 inches in diameter, is 53
iniles away, in Fredericksburg, Va. Nep-
tune is a little smaller, 4 feet, 4 inches in
diameter. It is 824 miles distant, which
would place it in Pennsylvania, south of
Harrisburg. And Pluto, at its mean dis.
tance, is 109 miles away. This would put
it, t ball 6% inches in diameter, in Chester,
Pa., a litte south of Philadelphia.

Finally there are the asteroids. These
are a group of tiny planets, some a mile or
less in diameter, that move generally in
orits between those of Mars and Jupiter.
Many thousands are within reach of great
telescopes. On our model these would be
represented by a truck load of sand and
pedbles, scattered around a circle about eight
miles from the Capitol.

The total area within the circle represent-
ing Pluto's orbit would be about 37,600
square miles. With nothing in this region
except the dome, the nine balls, ranging
from a few inches to 14 feet in diameter,
plus the sand and pehbles, you can see how
empty the solar system actually is!
