Haithabu — Entdeckung neuer Funde durch hochauflösende kleinseismische Messungen

A high-precision seismic reflection method has been developed for investigating archeological objects which are hidden in a mud-layer of the Haddebyer Noor, a lake in front of the old Viking settlement Haithabu near Schleswig. Wooden and metallic objects larger than about 30 cm could be detected and mapped. Some of the mapped objects have been rescued by diving operations. Others, like wooden harbour constructions of unexpectedly large dimensions, and a large (second) shipwrack were left conserved in the mud. All finds provide a new picture of this old Viking settlement showing that its inhabitants had a far higher stage of development than hitherto suspected.     

More news about quarks

The “constituents” quarks and leptons of matter (with rest-mass) are compared with the historical development of “elements” in chemistry. If unsaturated quarks induce high (and at the moment unpredictable) rest-masses above l0GeV, we have a new view of nuclei comprising (2Z + N) u-quarks and (Z +2N) d-quarks in their low-energy states, without any reference to protons and neutrons as permanent building-blocks. Recent studies of quarks and possible rishons (sub-quarks) and technicolour hadrons are reviewed, and the rôle of identity and cardinality in quantum mechanics analyzed.
