... John Backus in New Mexico, 1976 . ... Other manufacturers came later with Fortran compilers for their machines and in 1962 IBM introduced the extended Fortran IV, which was the base for the 1966 agreed American standard ANSI X3.9 - 1966. ... An HTML version of the Fortran 77 Standard is now available! ... The purpose of the work on a new standard version was to make Fortran usable and efficient language for scientific and technical computations during the nineties. ... Parallel execution . ...

... The group of radio emitting X-ray binaries (XRB's), such as SS433, Cyg X-3, LSI , Cir X-1, etc., exhibit highly variable bursting radio emission interpreted as synchrotron radiation from relativistic electrons. ... In this paper, a numerical model for radio outbursts in XRB's is developed. The model is based on a process of continuous injection of relativistic particles into a spherical expanding plasmon, ejected following a transitory supercritical accretion event onto the compact star. ...

... The Armagh Observatory (see http://star.arm.ac.uk/) is the oldest scientific institution in Northern Ireland, founded by Archbishop Richard Robinson in 1790 as part of his dream to see the creation of a university in the City of Armagh. ... The Astropark, which is managed by the Observatory, includes two sundials and scale models of the solar system and the Universe, and features a number of outdoor exhibits and interpretation panels (see http://star.arm.ac.uk/astropark/). ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . ... Astronomers can also determine the speed a galaxy is moving by breaking up its light into its component colors, rainbow-fashion. ... This pattern is now called "the expanding universe", since the entire universe of galaxies seems to be moving away. ...

Next: Survey Methods Up: THE DEEP X-RAY RADIO Previous: THE DEEP X-RAY RADIO . Blazars are the most extreme variety of AGN known. ... The beaming hypothesis has been successful in reproducing the luminosity function of samples of blazars (e.g., Padovani & Urry 1990, 1991, 1992; Urry, Padovani & Stickel 1991), allowing the derivation of class properties such as the range of Lorentz factors and opening angles in the radio band (and also in other bands for BL Lacs). ...

Next: Methods for Structuring and Searching Very Large Catalogs . ... We have explored two automated classification methods: supervised classification using Artificial Neural Networks (ANN) and unsupervised classification using Self Organized Maps (SOM). These methods are used to classify IUE low-dispersion spectra of normal stars with spectral types ranging from O3 to G5. This paper describes the application of automated methods to the problem of the classification of stellar spectra. ...

... The concept of continuous solar wind developed in 1950's. First, Biermann (1951, 1957) observed comet tails as they passed close to the Sun , and explained the observed tail deflection by a continuous flux of protons from the Sun. Then Parker (1959) showed that the solar corona must expand, and called the outward streaming c
