| NEW YORK, October 1.-The
phenomenal advances made recently
by the radio art are, resulting in the
creation of new professions more or
less differentiated from the parent
science of electrical engineering, ac-
| cording TO study of the subject sub
| mltted to the radio section of AS
sociated Manufacturers of Electrical
Supplies by DR.. Alfred n. Goldsmith,
| noted radio scientist
The specialization arising out OF
the complex technical problems OF
| radio has already esta ablished radio
engineering as new and important
profession. DR.. Goldsmith points out,
| and further development along these
! lines appears not unlikely. Broad
casting is calling into being the
| broadcasting engineer. and we may
| soon have college degrees for the
radio telegraph engineer and the
radio telephone engineer. in the same
way Is we have electrical. mechan-
ical and civil engineering degrees.
Even these divisions may be split up
| into receiving engineers and trans
| mission engineers.
Sweeping Improvement Seen.
The experimental work now being
| done in American laboratories by
| leading engineers promises sweeping
| improvements and far-reachine in
noVations in the radio art, says DR.
Goldsmith. Discussing the lines
along which radio is advancing. he
predicts that radio broadcasting is
sure to be extended until there can
be sent to every home in the coun-
try the best available music. the
most important educational material
or political information and all that
can be appreciated by the sense of
hearing. The reproduction of the
messages that broadcasting brings
into the home will be completely
faithful in character.
Indeed, even now" DIR. Goldsmith
writes, the best radio receiving sets
with their modern loud speakers can
give a fidelty of reproduction which
will satisfy even discriminating must
clans. and it may be stated that the
electro acoustic art of sound rcproduc-
| tion by electrical means is advancing
| by leaps and bounds
Range VIII Increase
| 80 far ordinary radio telegraph
! communication over long distances is
concerned. il is clear that the range
of the stations of today for reliable
communication Will be greatly in
creased and that their freedom from
extraneous disturbances of reception
VIII be increasingly insured.
| 'Teledynamics, or the control of
| mechaniSmS at distance, can also
| be accomplished by radio. Ships. to-
| pedoes and aircraft have been direct
! ed to a distant target or caused to
pursue a desired course by radio.
| Such telcdynamic systems may be
either an appalling addition TO the
| horrors of war or great asset to
the arts of peace, depending on how
! the people of the world uutilize them.
And, finally, there is somewhere
! ahead of us the achievement of
| another age-oid dream. Seeing a dis
| tant scene by radio is conceivable
and the broa dcasting of the appear
| ance of stage and the actors on
| il, as well as their speeches or songs,
| is well within the realm of possi-
bility. In the years to come the limi- =
| tation of the sphere of the human
senses to the immediate neighbor-
hood may be entirely removed. The
