SHOW IN BROOKLYN
DRAWS RADIO FOLK
Million Dollars Worth of
Equipment Furnishes Plenty
to Discuss.

Despite the fact that one week is
the usual length of time that any show
can run in New York. the Brooklyn
Radio Show at the Ice Palece is en-
tering It's second week tomorrow with
large numbers eager to look over the
million dollars worth OK equipment on
view.
The members of the Electrical Con-
tractors Association of brooklyn and
Queens. who are running the shcw, have
discovered in the course IT their busy
week that the patrons Of the exhibition
can be divided sharply into two classes
those who know nothing at all about
radio and those who know everything
about il. The experts explaining things
have come to view every one at the
show cautiously. for 4 twelve-year
boy, whose thoughts would not seem to
ascend above Eskimo pie or mild old
gentleman with the eye oil a book col
lector may turn out to kroH much more
about the theory or practice OF radio
than they do themselves

the average visitor an earache and even
puzzles some of the contractors. Their
scorn for the species which seeks to
learn something about I'd ,io is scorch-
ing.
The inquiring ones, however. seem. in
this mechanical age, to have an cleo
trical grounding which enables them to
pick up the theory of radio In quick
time. Their greatest confusion arises
from the fact that radio sets are by no
means standardized as yet. Ore set may

turn; another in panels pristling with
ali sorts of alarming gadgets and some
are heterogeneous collections of scat
tered apparatus resembling the insides
of a chess automaton.
The question most frequently asked
at the show is. who invented radio?"-
a question which requires an illustrated
lecture to answer. Many of hose pres
ent appear TO consider It in much the
same light as washing machine The
answer made by one well known exhib-
itor is as follows
NO one person invented radio. One
might as well ask who invented the au-
tcmobile as to ask who invented radio.
Many people believe Marcori was the
first man to receive or transmit mes
sages by wireless, but hs was not the
first TO accomplish this.
I'm 1860 James Clark Maxwell, a
Scotch physicist. published n paper on
The Electromagnetic Theory of Light
The development of this theory has led
eventually TO the radio, for, Il. Its time.
1t was a bold departure from accepted
theories and was proved by Maxwell
by mathematics, as far as mathematics
can prove, that electrical waves could be
produced in the ether.
twenty-five years later Heinrich
Hertz. young experimenter In the
laboratory Of the University OF Bonn,
found those waves which had been dis
covered automatically by Maxwell
Hertz was the first man to produce those
waves and detect them The waves
were known to science thereafter as
'Hertzian waves
''Marconi. the Italian inventor. picked
up the theories Of Maxwell. furthered
the discoveries Of Hertz and conducted
experiments with the end I'm view of
commercializing these mysterious waves
by harnessing them to work for man
kind
After Marconl. q score OF inventors
made contributions TO the science. Their
labors have made radio telephony the
modern marvel"
Several unusual features In addition
to the usual radio concerts and demon
strations are planned for this week.
Tomorrow night city officials and MEM
bers Of the Chamber OF Commerce. the
Brooklyn Motor Vehicle Dealers Asso-
ciation. the Brooklyn Florists Assocla-
tion. The Real Estate Board of Trade
and similar organizations Will attend.
A special musical program will be given.
on Wednesday ladies' night will be
observed. At each booth will be dis
played some sort of electrical appliance
OF feminine appeal On the closing
night. Saturday. the contractors will
