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. ...

... To avoid extensive numerical calculations in the statistical simulations, we treat the continuous evolution of each binary component as a sequence of a finite number of basic evolutionary states (for example, main sequence, red (super)giant, helium (Wolf-Rayet) star,     hot WD), in which stellar parameters significantly differ from each other. ... Figure 2: Schematic representation of the typical evolutionary track of a massive binary system with normal and compact star stages indicated. ...

. This schematic diagram shows how scientists think the universe has evolved from the Big Bang to the present day. Data from the UKIRT, VLT, and Subaru observatories allowed astronomers to take four precise and comparable snapshots of the universe when it was, 2, 4, 6 and 9 billion years old, each containing hundreds of star-forming galaxies. By comparing the different snapshots, astronomers were able to accurately track what has changed over the past 11 billion years. // illustration by CXC/NASA/NOAO/KIPAC

What follows is a brief list of benchmarks and discoveries that shaped our ideas on atoms and nuclei. ... Discovery of electrons . ... Comparing this to Faraday's results, one could get " Avogadro's number ", the number of (say) hydrogen atoms in one gram of hydrogen--an enormously large number. ... Similarly, energized atoms are only allowed to exist in one of a number of energy levels. ... By the way, Avogadro's number is 602,000,000,000,000,000,000,000 (6.02 10 23 ) molecules in 1 gr hydrogen. ...

. You can display the line by line difference between two files with the diff command. diff file1 file2 . The information given by the command tells you what changes need to be made for file1 and file2 to match. If there is no difference between the files you are returned to the shell prompt . diff indicates which lines need be added ( a ), deleted ( d ) or changed ( c ). Lines in file1 are identified with a ( < ) symbol: lines in file2 with a ( > ) symbol. Examples . Did You Know? .

... In constructing a long-term scheduler for ESO telescopes, Johnston, Chavan and Albrecht (1995) employed a cost function for installation of the IRSPEC since a one day instrument change time is needed in this case. ... In the case of CFHT, certain instrument changes require a telescope upper-end change (e.g. from cassegrain to coude). ... The scheduling strategy was modified to select observations on the basis of the upper-end and instrument being used. paragraph41em 1ex plus .5ex minus .5ex-1em . ...
