More than a decade has passed since pulsars were discovered at
Cambridge by J. Bell and A. Hewish. The past 13 years have seen ex
tensive and at first rather hectic research, and a considerable
amount of observational and theoretical knowledge has been
accumulated. Looking back over one decade of pulsar research, it
seems worth while to ask what the real impact of the detection was
and if our view of the universe has changed as a result of this
discovery. The excite ment of the first months and years has ebbed
down considerably, with the result that pulsar research has become
the task of a few scientists, working in small groups, scattered
over many countries. As more and more knowledge was acquired,
pulsars changed eventually from the bizarre pUlsing objects -- as
they were considered in the beginning -- to more normal stars of
astrophysical interest. Still, pulsars are the manifestation of
matter in its most extreme form -- neutron star matter -- for which
an equivalent can be found on earth only in the very nucleus of an
atom. Neutron stars were predicted quite early in the history of
modern astrophysics, and although many of their features were
already known from theoretical studies, astro physicists were not
sure if we had the slightest chance to actually "see" these
objects. It therefore took some time after the historical detection
paper of Hewish and coworkers before astronomers became con vinced
that pulsars were neutron stars."
