Prof, Perm Species
on [Topographical
Mapping of U. S.

Manama sill
Commended

The name of Professor John C.
Penn of the civil engineering depart-
ment was added to the list of dis-
tinguished speakers of the W.C.F.L.
educational radio series sponsored by
the Institute. Professor Penn spoke
last Saturday on the subject of topo-
graphical mapping of the‘ United
States with particular reference to
the Hayden-Ickcs Bill now pending
in Congress. The program was the
second in the new series in the field
of civil engineering, the fourth series
since the broadcasts began. The pro-
gram» was heard at the usual time
from 7:00 to 7:15 p.m. Saturday eve-
ning. Mr. Alexander Schrciber, pub-
licity director of the Institute, acted
in his usual role of questioner and in-
terpreter.

The Hayden-Ickes Bill provides a
plan for a very necessary topographic
mapping of the United States, Pro-
fessor Penn pointed out. The recom-
mendations for the bill have been is-
sued from the offices of the Director
of the United States Coast and Geode—
tic Survey of the Department of Com~
mercc and the Director of the United
States Geological Survey of the De-
partment of the Interior to provide
for the very necessary replacement of
obsolete maps and for the mapping of
as yet unmappcd territory. “About
fortyvsix per cent, or nearly one and
a half million square miles is entirely
unmappct," Professor Penn revealed.

Cost of Eighty Million

Specifically the bill does not pro—
vide for the mapping of all the un-
mappcd area, yet contemplates a rea.
sonablc program of mapping of over a
million square miles of territory. Such
a program would take about twenty
years to complete, and involve an ex-
pcnsc of approximately eighty million
dollars, four million dollars annually.
Such mapping would be topographic,
that is show differences in elevation
such as contours of hills, distances
above sea level and so forth in addi-
tion to representation of surface fea-
tures as found in less extensive maps.

As a justification for passing such
a bill, Professor Penn argued: ”The
plan may be considered one to pro-
vide work for idle engineers and so-
callcd white collar men. Or it may
he considered in a worse light, an»
other means of spending money. I
use these words with a great deal of
hesitation. I like to conceive the plan
to be a worth~whilc public work that
should be expedited . . . done now
while men and money are available. 1
want to show that this project has
merits all of its own, that it is econom‘
ically sound."

Next Week—Highway Design

Mr. Schreiber closed the program
by commenting: “It is the duty of en-
gineers, like yourself, Professor Penn,
and surveyors, to make their needs
and the needs of the country known
so that this plan can be properly car-
ried out."

The civil engineering scrifls will be
continued at the usual time of 7:00
p.111. next Saturday. The subject of
the broadcast will be concerned with
highway design for safety in driving.
The guest scientist who will partici-
pate was not announced.

Physics Classes Visit
Rosenwald Museum

 

Members of the Physica classes
were conducted through the newly
opened West Wing- of the Museum
of Science last Friday, March 18.
The tour, which was directed by
special guides furnished by the Mu-
seum was hold all afternoon, the stu—
dents attending when their classes
allowed them to take part. Queries
pertaining to exhibits were explained
by the guides and faculty members
of the Physics department.

A feature of the tour was a pre-
view of a Sound Section by Dr.
Brown of the Museum staff. This
portion of the museum is still in con-
struction and is not open to the gen-
eral public. The section contains
various experiments illustrating fun-
damental principles of sound. Of
special interest to the students Was
the Whispering Gallery. This spec—
ially constructed room was a source
of amazement as members at one
end of the room heard, with uncanny
loudness, the voice of a fellow stu-
dent some fifty feet away at the
other end of the room.

Last Tuesday saw a trek of the
seniors to Science Hall to hear Dean
A. A. Potter of the Purdue engineer-
ing school give an address on “Pro—
fessional Development." This subject
is of great importance to the grad-
uating class as it will come to their
attention in their jobs in a very short
time.

As his first point, Dean Potter
enumerated the statistics on the vari—
ous engineering professions. He stat~
ed that there were some 212,000 engi—
nears and surveyors in the United
States alone, of which about one third
belong to the American Engineering
Council. He also told of the major
engineering societies that have been
founded for the purpose of advancing
the profession and its functions.

Must Serve Community

After the preliminaries had been
disposed of, the Dean swung rapidly
into the discussion of what makes an
engineer. He gave his definition of
the professional man as “one pro-
fessing to have acquired special
knowledge, used by him either in
guiding, advising, or instructing
others.” The first point to be brought
out after this definition was the fact
that the engineer can not, in this day
and age, be just a man who knows a
lot about technology. He must also
he a man who is ready to serve the
community at large, accept social re—
sponsibility, and to keep up with the
work that is being done in his field.
One thing the speaker stressed was,
the necessity for the adoption and
obeying of a code of ethics for all
engineers.

 

 

 

ARMOUR TECH NEWS

genders Hear Purdue’s Bean, Potter,
Discuss ‘Frofessional Development’

An enlightening discussion of the
ways in which our form of govern—
ment cfl’ccts the engineer was next
mentioned. This phase of the profes-
sion is one that is not often called to
our attention, but one that is becom-
ing of greater importance because the
various state and federal agencies are
now employing a considerable number
of engineers.

Following this Dean Potter gave a
challenge to the graduates of the
near future. He outlined briefly a
story of the world since the last great
war, and of the great effects that
that event has had on the world today.
His picture was a rather sad one. The
challenge was that the young ongi~
ncers have it in their power to make
the world a better place in which to
live by using their knowledge to raise
the standards of life all over the
globe.

Must Have Personality

To assist the engineer in such a dif—
ficult task the following are necessary
to him: a pleasant personality, the
ability to work hard, a continuation
of education, the possession of a
thorough scientific back—ground, a
better than average knowledge of
economic and social forces, and mem-
bership in the engineering society that
includes his field of activity.

In closing his address, Dean Pot-
tcr enumerated the things that are
to be expected of the modern engi-
neer, what his attributes and qual—
ifications must be, and what his politi-
cal and social outlook must include.

 

Research Foundation
elontinues Work in
Science Applications

 

The Research Foundation was or~
ganized in 1936 for the purpose of
aiding industry in the fields of pure
and applied science. The foundation
has proven its value to companies
desiring investigation in technologi-
cal problems. The success of the
venture, a non-profit organization,
has shown itself by the rapid growth
of the departments until, at the pres-
ent time, there are thirteen active
research departments.

The following research activities
are a few of those now in progress:
’” Civil Research Engineeringw—has den
voted time to the investigation of in-
dustrial treatment of water supplies
which include filtration, precipita-
tion, and settling and also a study of
auxiliary equipment such as piping
and pumping.

Coal Research Engineering —— is
concerned with the determination of
output of heat from diil’cront vari-
eties of coal. The coal is crushed to
a standard one-quarter inch size and
then compared for specific gravity
with solutions of zinc chloride.
Powdered coal is placed in the adiam
hatic calorimeter to determine its
heating value. The powdered coal is
ignited while in the water jacket. The
rise in temperature of the liquid in—
dicuted the BTU output of a specific
type of coal.

High Pressure Research Lab-—
Pressures in excess of any previous
developed value have been studied
because of their effect on matter.
Under pressure of 580,000 pounds
per square inch, a glass window
in a cylinder is bent to a curvature

able additions that have gone to
make the Research Foundation so in-
