Bulk properties and flow

In this report, I summarize the experimental results on bulk properties and flow presented at Quark Matter 2004. It is organized in four sections: 1) Initial condition and stopping; 2) Particle spectra and freeze-outs; 3) Anisotropic flow; 4) Outlook for future measurements. A wealthy set of data related to bulk properties and flow had been presented at this conference. I will highlight on the results related to initial condition, partonic collectivity and thermalization in relativistic heavy ion collisions, emphasizing on the exciting results from recent RHIC run with Au+Au and d+Au collisions. The plots shown in this report are to illustrate the discussions and I refer the readers to presentations by various collaborations for complete dataset. Other important and exciting results, such as strangeness (K/π) excitation function from SPS [1] and pentaquark searches from various experiments [2], will not be covered in this summary. 1. Initial conditions One of the exciting results in forward rapidity (deuteron side) at RHIC is the observation of suppression of particle yields at and below intermediate pT [3] in d+Au collisions. The
