    Relativity theory has had a profound influence on our picture of matter by
forcing us to modify our concept of a particle in an essential way. (1)(In
classical physics, the mass of an object had always been associated with an
indestructible material substance, with some “stuff” of which all things were
thought to be made.)Relativity theory showed that mass has nothing to do with
any substance, but is a form energy. Energy, however, is a dynamic quantity
associated with activity, or with processes.(2)(The fact that the mass of a
particle is equivalent to a certain of energy means that the particle can no
longer be seen as a static object, but has to be conceived as a dynamic pattern,
a process involving the energy which manifest itself as the particle’s
mass.)
    (3)(This new view of particles was initiated by Dirac when he formulated a
relativistic equation describing the behavior of electrons.) Dirac’s theory was
not only extremely successful in accounting for the fine details of atomic
structure, but also revealed a fundamental symmetry between matter and
anti-matter. It predicted the existence of an anti-matter with the same mass as
the electron but with an opposite charge. This positively charged particle, now
called the positron, was indeed discovered two years after Dirac had predicted
it. The symmetry between matter and anti-matter implies that for every particle
there exists an antiparticles with equal mass and opposite charge. Pairs of
particles and antiparticles can be created if enough energy is available and can
be made to turn into pure energy in the reverse process of destruction.(4)(These
processes of particle creation and destruction had been predicted from Dirac’s
theory before they were actually discovered in nature, and since then they have
been observed millions of times.)
    The creation of material particles from pure energy is certainly the most
spectacular effect of relativity theory, and it can only be understood in terms
of the view of particles outlined above.(5)(Before relativistic particle
physics, the constituents of matter had always been considered as being either
elementary units which were indestructible and unchangeable, or as composite
objects which could be broken up into their constituent parts;)and the basic
question was whether one could divide matter again and again, or whether one
would finally arrive at some smallest indivisible units.
