An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...

You will need to understand how to set file access permissions numerically before reading this section. Every time you create a file or a directory, its access permissions are set to a predetermined value. ... The values in the mask are subtracted from these values to give a default value for access permissions for the files and directories created by you. For example: 777 (system value for directories) -077 (value of the umask) --- 700 (default access permission of rwx------) . ...
