The NATO Advanced Study Institute 'The Many Faces of Neutron Stars' was the fourth in a series focusing on the astrophysics of neutron stars, which started with the ASI 'Timing Neutron Stars' (Qeme, Turkey, April 1988), and as followed by 'Neutron Stars, and Interdisciplinary Field' (Agia Pelagia, Greece, September 1990), and 'The Lives ofthe Neutron Stars' (Kemer, Turkey, Septem- ber 1993). The first ASI had as its theme the main types of observations from which we infer the properties of neutron stars, i.e., the timing of radio pulsars and accret- ing neutron stars in X-ray binaries. The...

Reports the main results of an international workshop in Erice, Sicily, April 1991, at which astronomers and computer scientists reviewed the evolution of data analysis in astronomy during the past decade. The 32 papers cover systems and archives; the HST, ROSAT, and GRO missions, and future mission

In this book are reported the main results presented at the "Fourth International Workshop on Data Analysis in Astronomy," held at the Ettore Majorana Center for Scientific Culture, Erice, Sicily, Italy, on April 12-19, 1991. The Workshop was preceded by three workshops on the same subject held in Erice in 1984, 1986 and 1988. The frrst workshop (Erice 1984) was dominated by presentations of "Systems for Data Analysis"; the main systems proposed were MIDAS, AlPS, RIAIP, and SAIA. Methodologies and image analysis topics were also presented with the emphasis on cluster analysis, multivariate...

This book contains the invited and contributed lectures presented at a meeting organised in the context of the XVIII general assembly ofthe IAU, held in Patras, August 19, 1982. Roughly one hundred scientists attended this meeting, the discussions were livel- sometimes heated - and the original time span allocated to the meeting was as a result, comfortably exceeded by about 50 % . The aim of this meeting was to determine the role of galactic gamma-ray astronomy within the general concept of galactic astrophysics. The timing, at the end of the COS-B mission, was regarded as opportune, because...

Every human being is aware of the flow of time. This fact is embodied in the existence of such notions as the past and the future, the two domains being separated from each other by the single moment of the present. While the past is regarded as fixed and definite, the future is viewed as unknown, uncertain, and undetermined. The only perceivable moment is the present, the now' - the ever-changing point moving from the past into the future.
Physics tells us a different story: not only are the vast majority of physical laws time-reversible, but the concept of the now' itself has no place...
