6 All About Inventions
which Hertz followed. His work was thorough and
conclusive.
His achievement was so sensational as to stimulate
scientists throughout the world. One and all picked
up the threads of research at the point to which they
had been carried by Hertz. Now the curious point
is that the German philosopher had no idea of apply-
ing his discovery to the conveyance of signals, corre-
sponding to sounds, through the ether. He pursued
the subject in the effort to solve the problem of light,
and at the time his results were considered to be
the most valuable contributions to this subject.
The term ether is one which is misunderstood by
the average individual. Generally speaking, it is
assumed to be a synonym for atmosphere, but this
is a serious mistake, as it has nothing to do with the
atmosphere surrounding this earth. As is well known,
the air we breathe constitutes a layer or invisible
blanket covering this globe which, as one ascends,
grows thinner or rarer in its composition, until at
last, at a certain height, it is no longer encountered.
But from the edge of our respirable air to other worlds
a certain subtile medium exists which fills all the
apparent empty space. This is the medium which
scientists have designated ether. More than this, it is
claimed to permeate all matter even in this atmo-
sphere-covered sphere. That this is so was demon-
strated by Marconi when he sent his signals, corre-
sponding to the dot and dash of the Morse alphabet,
through hills and buildings upon Salisbury Plain,
although the selfsame phenomenon had been pre-
viously observed in the laboratory.
Now these electro-magnetic waves, when thrown
