The Story of Alchemy and the Beginnings of Chemistry
·
M. M. Pattison Muir
168
The
continued
study
of
the
properties
of
the
minute
particles
of
radio-active
substances--a
new
name
is
needed
for
those
most
mutable
of
material
grains--must
lead
to
discoveries
of
great
moment
for
chemistry
and
physics.
That
study
has
already
thrown
much
light
on
the
phenomena
of
electric
conductivity;
it
has
given
us
the
electron,
a
particle
at
least
a
thousand
times
lighter
than
an
atom
of
hydrogen;
it
has
shown
us
that
identical
electrons
are
given
off
by,
or
are
separated
from,
different
kinds
of
elementary
atoms,
under
definable
conditions;
it
has
revealed
unlooked-for
sources
of
energy;
it
has
opened,
and
begun
the
elucidation
of,
a
new
department
of
physical
science;
it
has
suggested
a
new
way
of
attacking
the
old
problem
of
the
alchemists,
the
problem
of
the
transmutation
of
the
elements.
