... Do you know why we have seasons on Earth? ... Even if you offer students the great activities developed by the Harvard researchers, or the great activities in ASP's teacher resource book, The Universe at Your Fingertips , your students still won't learn anything unless they work hard and think about their work. ... But none of these are worth a hoot unless they are also accompanied by hard work on students' part. ... The key to success in astronomy is the same as it is in everything else: hard work....

Geometry of X-ray sources in accreting black-hole binaries Andrzej A. Zdziarski N. Copernicus Astronomical Center, Warsaw The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ...

. Remove a file that has hard links to it the same way as you would remove any other file: rm filename(s) . Any files that were created by making hard links to the filename will continue to exist in their own right. Removing a file to which symbolic links have been made has a different effect. Although the linkname remains, the actual file that this name points to does not. Trying to use a command on the linkname will give you the message: command : filename : No such file or directory .

... The hard gamma radiation from AGN is produced most probably in the relativistic jets observed in the considerable part of these objects. In the center of AGN (and may be of all other galaxies) there is a supermassive black hole surrounded by the accretion disk, which is the source of the energy in these objects. ... The problem of particle acceleration in the AGN jets is very important: the time of the electron energy losses in the jets is usually much less than their life time. ... next page . ...

... Our Galaxy . ... Universe . ... One of the Hubble Space TelescopeтАЩs goals was to accurately observe Cepheids in the most distant galaxies known (we knew they were far away, the problem was saying just how far). ... This work is becoming ever more refined; in January this year astronomers revealed that they had identified the farthest galaxy yet seen in a Hubble image. ... Thanks to the Hubble Space TelescopeтАЩs superb observations we can say that the universe is 13.75 billion years old. ...

In today's fast-moving world it becomes harder and harder to keep yourself healthy and fit. In order to earn health some people try to attend aerobics or gym, and others want to make the way to absolute vital energy as easy as they can, not even thinking of the results. But the effect of consuming tranquilizers and using extasy in order to raise your mood are often unfavourable. ... Teenagers found some other ways of relaxing, such as alcohol, drugs, smoking etc. ...

... With current telescopes, finding dusty starbursts in the early universe is hard work. What you really need is a mm-wave telescope with really good resolution and collecting area on a high, dry site. ... Not only could you find high redshift dusty galaxies, but you could use their molecular emission lines to map them, measure their velocity fields, temperatures and chemical compositions. ... It is obvious to you that this is the best way to study the early universe and the formation of galaxies. ...

A descriptor , also commonly called a file handle is an object that a program uses to read or write an open file, or open network socket, or a variety of other devices. ... The operating system enforces a limit on the number of descriptors that a program can have open at a time. ... One is a kernel limitation, depending on your operating system you will either be able to tune the number of descriptors available to higher numbers (this is frequently called FD_SETSIZE ). ...

... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...
