Up to now it was regarded as an interesting although a bit academic topic. This has changed recently due to growing interest in astrophysical and high energy physics applications. This paper does not pretend to be a complete review of the present state to research in the field of relativistic hydrodynamics. RH is viewed from the physical point of view, and those points which are quite confused in the literature are discussed. In particular the role of the observer, the problem of physically motivated choice of the hydrodynamical variables, and the invariance of the constitutive relations are discussed. Most of those problems will be put into a proper perspective by the careful analysis of the relativistic kinetic Boltzmann equation.}, type={Text}, title={Relativistic hydrodynamics}, URL={http://rcin.org.pl/Content/69982/PDF/WA727_18044_43-5-1991_AMS_Ekiel-J-04.pdf}, keywords={Mechanika stosowana - czasopisma [KABA]}, }
