University of Thessaloniki in Greece for giving the dinner talk on the most astounding ancient Antikythera mechanism. We would also like to thank Victor Gomer and the staff of the Physikzentrum of the Deutsche Physikalische Gesellschaft in Bad Honnef where the conference took place. Last but not least we would like to thank all unnamed helpers, without whom the organisation of this conference would not have been possible. Financial support for this conference was granted by the Deutsche Forschungsgemeinschaft (DFG) Sonderforschungsbereich project number SFB 956. We also acknowledge support from the European Community Framework Programme 7, Advanced Radio Astronomy in Europe, grant agreement no. 227290.

amounts to up to a million billion [1015] times the mass of our Sun, is composed of hot gas and dark matter. In this case, the cluster being observed has the designation MACS J2135-010217 (or MACS J213512.10-010258.5), and is at a distance of about four billion light-years. [2] Gravitational lensing is an effect forecast by Albert Einstein's theory of general relativity. Due to their gigantic mass and their intermediate position between us and very distant galaxies, galaxy clusters act as extremely efficient gravitational lenses, bending the light coming from background galaxies. Depending on the cluster mass distribution a host of interesting effects are produced, such as magnification, shape distortions, giant arcs, and multiple images of the same source.

Swinbank et al., DOI 10.1038/nature08880) to appear online in Nature today. The team is composed of A. M. Swinbank, I. Smail, J. Richard, A. C. Edge, and K. E. K.
