NEW YORK, May s.-Speculating
upon the rapid advance made by
radio in the past few months. John
V. l.. Hogan. radio expert and
former president Of the Institute "f
Radio Engineers, said today that
within fifty thousand or 100 900 years
radio might become passe, fol by
that time people may bc able to
communicate TO one another, by
thought transference.
Instead of radio waves ;here will
be thought waves and the human
animal may progress to such a degree
that speech will become a lost func-
don. There'll just be thought trsnn'
ference. Perhaps.
The idea is suggested, Hogan says.
by the fact that there has been
evolution in the sense Ct nearing.
which today In more acute than 1t
was many years ago.
Radio also Is in a stage Of evo.
luton" he said. Meanwhile radio
apparatus and static Is with US.
Radio engineers are giving consider
dition which makes sending OF RADIO
Can't Define Static.
The chief difficulty" said Hogan.
''is that nobody knows exactly what
static Is or how IL may always be
overcome. But we do know this at
mospheric disturbances costs a loss
OF untold amounts OF money yearly.
Static creates parasitic waves in
the ether. very similar 10 the
waves caused by radio signals. II
Is this very similarity between the
parasitic storm waves and the regu.
lar signal waves that make IL so
difficult TO distinguish one from the
other. Still, as proof ot The progress
being made by radio engineers to
overcome static, ii may be said that
reduction OF 80 per cent. has beeen
made during the last ten wears.
No one knows where static origi.
mates. Some believe IL comes from the
center OF the earth while others are
convinced that II is ovrheated, or
that IL comes from the region OF
the Gulf stream. where sc many
storms originate. or again that 1t Is
| formed from small electric disturb.
ances that are not great enough tc
be called storms in themselves and
which disturbances are Soing on con.
stantly all around us. Still Others
contend that 1t comes flnm th :
| ground directly under our feet.
"Broadcdsting is not nearly &c
much disturbed 10y static an r dis.
tance work and this for the follow
! ing reasons:
The first is that br oadcastlne
! radio telephone is done through
high frequency or snort waves
whereas long distance. under tcie
| graph uses radio low frequency. OF
long waves. Atmospheric disturb
ances affect long wave lengths, more
than they do those of high f,e
! quency.
Second. the long distance lie
J tween stations operating across tn
ocean renders them more liable "a
atmospheric disturbances than in
the case OF the broadcsstirs radio
! phone stations working over CON
/ paratively short distances.
Third. the human ear is better
ada pied. through years ~ evolution
TO listen to speech or music used IN
radio teie phony) than the dots aid
dashes OF wireless teles:apNy. and
/ hence is LEES disturbed bv Amos
pheriC noises.
Economy Soon.
"In the future we may eXpe,t that
! the remaining five per cent. OF at,
mosphere disturbances will he large
! ly, II not entirely eliminated and
that, therefore. both radio telephony
and wireless telegraph messages
will be sent more economically and
for greater distances than has so far
been possible"
