An Error of Omission
We read with great interest a recent article entitled “Posterior Mediastinal Sarcoidosis” by Rosseel et al (Chest 1986; 90:462-64). As the authors indicate, posterior mediastmnal lymphadenopathy in sarcoidosis has rarely been recorded. It may be expected that frequent use of CT in these cases may change our current concept about the incidence of such involvement in the disease, and additional w...
متن کاملAn omission in Special Relativity
In Special Relativity there are infinitely many equivalence classes of frames of reference. In each such class every two frames of reference move uniformly with respect to one another. It appears that the following questions have never been asked : In which of such equivalence classes of frames of reference is Special Relativity supposed to hold ? How can we identify such a class, and do so the...
متن کاملThe CBM experiment at FAIR
The high-intensity heavy-ion beams of the FAIR accelerators, together with the planned Compressed Baryonic Matter (CBM) experiment [1], offer unique possibilities to produce and to investigate baryonic matter at highest densities in the laboratory. According to calculations, baryon densities of up to 10 times saturation density (comparable to the ones in the inner core of neutron stars) and ene...
متن کاملThe PANDA Experiment at FAIR
The PANDA experiment is one of the large installations at the future international Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It will be located at an internal target station of the High Energy Storage Ring for anti-protons. The PANDA physics programme focusses on charmonium spectroscopy and the search for glueballs and hybrids, but also includes hypernuclear physics...
متن کاملWhen an Action is an Intentional Omission

There are occasions where they might be used to attribute intentional omissions rather than intentional actions. One can thus explain a number of puzzles that have been taken to be puzzles about the concept of intentional action: the Knobe effect, the connection ...
