CLEVELAND, Ohio, December 81
The numerous ways light and related
radiationS have been put to work in
solving problems Of life, energy and
the universe, win be a topmost subject
when American scientists gather here
Monday for an annual inventory Of
their work.
approximately 40 learned societies
and Is sections of the American Asso-
citation for the Advancement of Science
will hold 200 meetings. Five thousand
delegates are expected.
In order to present q comprehensive
picture Of she accomplishments of
science during the past year, presenta-
ton of 1000 papers will be required.
The subjects will range all the way
from biology to economics, from the
inbreeding Of corn to the progress of
industrializatifn In the Soviet Union;
from the cycles Of sun spots to business
cycles.
Stars 70 BE Discussed.
The stories told by light from dis
tant star gals:des will be related. DR..
Harlow ShaplAy, director Of the Har-
ward University Astronomical Observa-
tory. will tell Of explorations through
space to find the center of the universe
and learn the characteristics Of great
star clusters.
Giant telescopes viii come up for
discussion, giant telescopes like the one
to be installed. at the California Insti-
tute Of Technology, which, it is said,
will enable msn to penetrate distances
10 times farther than he is permitted
now. Mechanics Of the telescope will
be the subject 81 paper by Z. p. Bur-
reIl of Warnee & Swasey. Roger L.
Putnam, trustees Of the Lowell Observa-
tory, Flagstaff, AriZ., will tell how as
tronomers at the observatory searched
their way through the sky to fulfill the
predictions Of tde late Prof. Lowell that
the suns family Of planets had a ninth
member. Scratching Out Pluto" VIII be
the subject.
Using the pioneering Of the president
of the Scientific Association-Dr.
Thomas Hunt Morgan Of the California
Institute-as q basis for study several
scientists will tell Of the latest observed
effects Of ultra violet and Xrays on
changing the factors of heredity. Some
of these changes give rise to new
characteristics, which may be inherited
by plants and; animals.
Recently scientists have been making
numerous observations on strange radia-
tons given off by growing onion roots
and yeast cells. Some think these
nature Of Wtaf energy. This will be an
important topic at the sessions.
The scientists will show how the
power Of the microscope has been
augmented in zone instance to such an
extent that the interior walls Of the
tiny plant cells have been photographed.
It is also being used now in conjunction
with the moti0n picture camera.
Getting the movies to talk naturally
and pleasantly will be discussed by
Charles w. Hewlett, research worker
for the General Electric Co, as one OF
the principal speakers during a sym
postum on acoustics.
Sound Absorbing Work.
At this symposium Paul e. Sabine,
director of the Riverbank Laboratories,
Geneva, Ill, will tell of ways to treat
interiors for absorbing as much as 30
to IS per cent of the sound and to treat
them without interfering with the deco
rative values.
Interferences with radio transmission
by spots that besmirch the face Of the
sun viii be explained by DR.. Harlan
Stetson, director of the Perkins Observa-
tory, Ohio Wesleyan University, Della
ware, Ohio.
The spots occur In major cycles OF III
years. A year ago, when they were at
their peak, they extended for 100000
miles across the suns face.
The problem of blowing to pieces the
atom-the tiniest particle Of matter
and then putting 1t back together, will
be the subject of the address by the re-
firing president, DR.. Robert A. Millikan,
chairman OF the executive council Of
the California Institute of Technology.
In the address he will approach the ex-
treme frontier Of physical science, where
work Is being done to lombard atoms
of gold for the release Of atomic energy.
