... Magnetic fields, subatomic particles, etc., traveling in different directions fill the universe. Do they deflect or otherwise affect one another? If so, isnт??t the information we get from them distorted? ... Neutrino astronomy, which is still in its infancy, is attractive because neutrinos interact so weakly with matter that few of these distorting effects occur.

. A regular expression is a concise way of expressing any pattern of characters. You construct a regular expression by combining ordinary characters with one or more metacharacters: characters that have special meaning for the shell . Regular expressions can be used to: . specify filenames . search file contents . change file contents . Commands differ in the range of the regular expressions that they support. Check the manual page for the command for further details.
