The solar system probably formed about 4.5 billion years ago from a giant disk of gas, dust and ice in space. ... All forms of life on Earth require liquid water to survive, so the presence of liquid water is a good criterion for deciding whether other planets in the universe could be habitable. Earth is the only habitable planet in the solar system. Venus, closer to the Sun, is too hot to have liquid water. Planets and moons in the outer solar system are too cold for liquid water. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

... To use system calls and library functions in a C program we simply call the appropriate C function (Appendix ). We have already met some system calls when dealing with low level I O - open(), creat(), read(), write() and close() are examples. ... All math functions such as sin(), cos(), sqrt() and random number generators - random(), seed(), lrand48(), drand48() etc. are standard math library functions.

. Strictly speaking, UNIX is not one single operating system, it is a family of operating systems. Different computer manufacturers produce their own versions of UNIX. Although these are mostly similar, there are small differences which can cause problems. The most obvious examples are the layout of the file system and the exact format of certain commands.
