Numerical Simulation of Jets,The reliability of published numerical simulations of fluid jets is assessed. It is shown that the resolution used in these calculations is much too low for the results to be of any use.

Dynamical Effects of Large-Scale Magnetic Fields in Jets,The possible dynamical effect of large-scale magnetic fields in astrophysical jets is discussed. They range from collimation and refocussing of jets to interaction between adjacent current-carrying jets.

The Sources and Their Models,c Nuclei (=AGN), Young Stellar Objects (=YSO), Binary Neutron Stars and Binary White Dwarfs. This similarity is remarkable in view of the vastly different environments and contrasts with the heterogenous models which have been advanced for their description.

The Central Engine,ipolar flows and jets from compact stars are similar and driven by the cores of accretion disks. Some difficulties of the black-hole model are discussed, in particular the problem of the missing ashes. The (super-)massive magnetised core model of an accretion disk (=SMC) is revisited.

,The Quasar Family — An Introduction and Taxonomy,he common terminology. The basic unity of all kinds of quasar activity is emphasised. Some differences between various family members are given and some interrelationships pointed out. Finally, it is emphasised that quasar activity at low levels is extremely common.

Robust

Unified Beaming Models and Compact Radio Sources,this was in fact a theoretical prediction (Rees 1967), although (as we shall see) there is still some debate about precisely what is moving. We can begin with something uncontroversial: the relativistic transformation of specific intensity (or surface brightness).
