“In this class I hope you will learn not merely results, or
formulae applicable to cases that may possibly occur in
our practice afterwards, but the principles on which
those formulae depend, and without which the
formulae are mere mental rubbish. I know the
tendency of the human mind is to do anything rather
than think. But mental labour is not thought, and those
who have with labour acquired the habit of application,
often find it much easier to get up a formula than to
master a principle”

upon that he did not change almost beyond
recognition

Model of molecular vortices
and electric particles
we can scarcely avoid the inference that light
consists in the transverse undulations of the
same medium which is the cause of electric and
magnetic phenomena
Einstein on Maxwell
Since Maxwell’s time, physical reality has been
thought of as represented by continuous fields,
and not capable of any mechanical
interpretation. This change in the conception of
reality is the most profound and the most
fruitful that physics has experienced since the
time of Newton
Maxwell’s sense of
fun is shown in this
poem to Thomson’s
galvanometer (an
instrument for
measuring current)
