For the first time in human history, developments in many branches
of science provide us with an opportunity of formula ting a
comprehensive picture of the universe from its beginning to the
present time. It is an awesome reflection that the carbon in our
bodies is the very carbon which was generated during the birth of a
star. There is a perceptible continuum through the billions of
years which can be revealed by the study of chemistry. Studies in
nucleosynthesis have related the origin of the elements to the life
history of the stars. The chemical elements we find on earth,
HYdrogen, Carbon, Oxygen, and Nitrogen, were created in
astronomical processes that took place in the past, and these
elements are not spread throughout space in the form of stars and
galaxies. Radioastronomers have discovered a vast array of organic
molecules in the interstellar medium which have a bearing on
prebiological chemical processes. Many of the molecules found so
far contain the four elements, C, N, 0, H. Except for the chem
ically unreactive He, these four elements are the most abundant in
the galaxy. The origin of polyatomic interstellar molecules is an
unresolved problem. While we can explain the formation of some
diatomic molecules as due to two atom collisions, it is much more
difficult to form polyatomic molecules by collisions between
diatomic molecules and atoms. There may be other produc tion
mechanisms at work such as reactions taking place on the surface of
interstellar dust grains."
