As suggested in the previous Chapter, Electricity and Magnetism
(or &
,
as they are known in the trade)
are ``weird'' phenomena because the palpable forces
they generate on objects seem to come from nowhere -
nothing is ``touching'' the objects and yet they are moved.
The related fact that we are unable to wilfully exert significant
electrical or magnetic forces directly on objects around us
using any combination of muscles or mechanical devices
removes
&
still further from
our personal sensory experience
and thus makes them seem ``weirder.''
Even the most seasoned
&
veteran
still experiences a sense
of primitive wonder when a magnet on top of the table moves
``by magic'' under the influence of another magnet underneath
the table.
On the one hand, this makes &
a fun subject to study.
On the other hand, it makes
&
hard to teach, because
it will never make ``common sense'' like nuts-and-bolts Mechanics.
C'est la vie. As our first foray into ``Weird Science''
it is only fitting that
&
should be something we know is there
but that we will just have to get used to instead of ever hoping
to rectify it with our common sense. It is, of course,
``common sense'' itself that is defective . . . .
