his nose. To be really creative, ideas have to be worked up and then
"put over", so that they become a part of man's social heritage. The
highly accurate pendulum clock was one of the later results of
Galileo's discovery. He himself was led to reconsider and successfully
to refute the old notions of falling bodies. It remained for Newton to
prove that the moon was falling, and presumably all the heavenly
bodies. This quite upset all the consecrated views of the heavens as
managed by angelic engineers. The universality of the laws of
gravitation stimulated the attempt to seek other and equally important
natural laws and cast grave doubts on the miracles in which mankind
had hitherto believed. In short, those who dared to include in their
thought the discoveries of Galileo and his successors found themselves
in a new earth surrounded by new heavens.

On the 28th of October, 1831, three hundred and fifty years after
Galileo had noticed the isochronous vibrations of the lamps, creative
thought and its currency had so far increased that Faraday was
wondering what would happen if he mounted a disk of copper between the
poles of a horseshoe magnet. As the disk revolved an electric current
was produced. This would doubtless have seemed the idlest kind of an
experiment to the stanch business men of the time, who, it happened,
were just then denouncing the child-labor bills in their anxiety to
avail themselves to the full of the results of earlier idle curiosity.
But should the dynamos and motors which have come into being as the
outcome of Faraday's experiment be stopped this evening, the business
man of to-day, agitated over labor troubles, might, as he trudged home
past lines of "dead" cars, through dark streets to an unlighted house,
engage in a little creative thought of his own and perceive that he
and his laborers would have no modern factories and mines to quarrel
about had it not been for the strange practical effects of the idle
