The universe from flat Earth to quasar a pelican paperback book by Isaac Asimov
Used very good.
published by Penguin Books
Over the past twenty-five years more has been
learned of the universe than in all man's history
before. We now know that it is at least
26,000,000,000 iight-years in diameter, pulsating
in a vast period of 82,000,000,000 years. With
the speed of light established at 186,282 miles
per second, the immensity of such distances
and times is awesome.
In this exciting book Isaac Asimov, Professor of
Biochemistry at Boston University and creator
of some of the most original science fiction,
turns his attention to science fact. He traces the
development of man's observations about his
own, and other, worlds, from the early theories
of Hecataeus, Eratosthenes and Galileo to those
of Max Planck, Hoyle and Gamow. With expert
clarity he also unravels the complexities of
modern astronomy, explaining just what is
meant when astronomers refer to Quasars, Dark
Nebulae, Receding Galaxies and other
phenomena.
This lively account ofa very fascinating subject
will impress the reader not only by what has
been discovered so far but also by the many
questions that remain unanswered'-
