It is our pleasure to present the Proceedings of the VI International Workshop on Relativistic Aspects of Nuclear Physics (RANP 2000). This time, the meeting took place in Tabatinga, a pleasant beach on the southern coast of Brazil, for the first time out of the city of Rio de Janeiro. This series of workshops started in 1989, aiming to stimulate Brazilian scientific activities on Relativistic Nuclear Physics, especially among young researchers and graduate students. The VI Workshop, held in October 2000, reflected the excitement created in the field by the start of operations of Brookhaven's Relativistic Heavy Ion Collider just four months earlier, in June. The new frontiers.
