Professors Of
Michigan Are
Given Honor'
Three Faculty Members
To Write Monographs In1
German 'Handbuch'
Three University of Michigan pro-
fessors have been selected to write
monographs in the new German
"Handbuch der Astrophysik" to be
published soon in Germany. They
are Dr. Otto Laporte, of the physics
department, whose subject is "The-
orie der Multiplettspektren"; the late
Prof. Ralph H. Curtiss, of the Astron-
omical Observatory, who worte on
"Classificatoin and Description of
Stellar Spectra"; and Dr. Heber D.
Curtis, director of the observatory,
whose subject is "The Nebulae."
The English word "Handbook" is
very far from being an accurate I
translation of the German "Hand-
buch," for instead of being a con-
venient pocket manual, the "Hand-
buch" strives to be a complete sum-
mary of existing knowledge in the
particular field under consideration.,
The great "Handbuch wer Physik"
comprises 24 large octavo volumes.
Such a work is an outgrowth of the
tremendous modern expansion in all
fields of science, making it difficult
for the research worker to obtain a
comprehensive view of the larger
aspects of his field of work and its
contacts with other fields. Mere
bibliographies of his field are un-
satisfactory in that they require a
great expenditure of time in separat-
ing past contributions of permanent
value.from theories which have been
discarded.
The Germans, with their innate
Teutonic thoroughness in sceince,
have been meeting thi sneed by the
publication of these great manuals
or summaries, encyclopedias in real-
ity, in various scientific fields. Each
separate treatment is written by some
authority in that particular field, so
that the completed work may repre-
sen the labor of dozens of specialists,
The treatment is in no sense popular,
but "streng wissenschaftlich"-a de-
tailed and exhaustive presentation of
the results of research and present
theories, accompanied by full bibli-
ographical references to the litera-
ture on the subject.
The "Handbuch der Astrophysik"
f wil be somewhat smaller than the
corresponding " H a n d b u c h der
Physik," probably about eight or ten
volumes. It is being published by
Julius Springer, Berlin.
Dr. Laporte's monograph, written
in German, fills 134 pages and is ac-
companied by 30 illustrations. It will
form chapter six of volume III-2 of
s the series. The contribution of Pro-
fessor Curtiss, written in English,

Will Address 4 American
Physical Society Group
On QuantumMechanicS
Prof. Otto LaPorte, of the physics
department, will leave Wednesday for
New York City to attend the one
hundred and eighty-third regular
meeting of the American Physical
Society, which will meet Thursday,
Friday, and Saturday. He will ad-
dress the group on "The Rotation of
a Heavy Body in Quantum Me-
chanics."
Three regular meetings of the so-
ciety are held every year. During
the Thanksgiving holidays a meeting
is held in Chicago; over the week-
end of Washington's birthday one is
held in New York, and in the spring
the members meet in Washington,
D. C.
In his address, Professor LaPorte
applies quantum mechanics to a
problem of which the classical ana-
logue was treated by a famous
woman mathematician, M a d a m e
Sonja de Kowalevski, in the year
1888. Madame Kowalevski was one
of the ~first women ever to success-
fully do mathematics, and conse-
quently her work is of even greater
importance.
Two other cases of rotational mo-
tion had been discussed previously by
Euler and La Grange, Professor La-
Porte said, in the beginning of the
nineteenth century. These were the
only cases that were solved for many
year until 1888; when Madame Ko-
walevski solved another case.
Her accomplishment started a flood
of papers, and was called a "real and
important progress in the study of
the movement of a solid body passing
around a fixed point."
Professor LaPorte is doing in quan-
tum mechanics what she did in class-
ical mechanics. Quantum mechanics
is a new kind of mechanics adopted
in the study of atomic and mole-
cular problems, Prof. LaPorte stated,
and was only discovered in 1926.

Putumayo river touched off the long predicted clash between the two
countries for possession of the upper Amazon port, Leticia. After
heavy fighting Colombian troops captured the town of Tarapaca, Putu-

Powell, of the military science de-

COME EARLY AND STAY LATE
FOR WEDNESDAY IS A HOLIDAY

An annual eclipse of the sun, in-
visible in the United States, is sched-
uled to take place Friday, Feb. 24.
It will be visible generally in central
and southern Africa, and South At-
lantic ocean and the southern and
central parts of South America.
The path of this eclipse crosses:
Aden in the British Arabia, Steph-
anieville on the western coast of
Africa, and Valdivia, Chile. It will
end about sunset in Arabia, and will
begin in South America at sunrise.
The central eclipse will begin about
5:58 p. m. central standard time.
Prof. Heber D. Curtis ,of the
astronomy department, stated that
it is only an annular eclipse of no
scientific value and no expedition
would be sent to observe it.

The local chapter will enter two
teams of ten men each in the compe-
titions, CaptainPowell said. He has
been selected by the national frater,
nity to stage the meet for them and
will be in complete charge.
Patrick J. McCaughey, '29E, pres-
ent national president of the frater-
nity, is the originator of the idea,
according to Captain Powell. The
local shoot will be directed by Paul
Firring, '33L, president of the chap-
tre here.
