This course will count for general studies
science credit, but both the lecture and lab must
be completed. You do not have to complete the
lecture and lab in the same semester.

  • WHY STUDY ASTRONOMY John R. Percy, University of
    Toronto Mississauga, Ontario
  • Astronomy is deeply-rooted in almost every
    culture, as a result of its practical
    applications.
  • Astronomy has obvious practical applications to
    timekeeping calendars daily, seasonal, and
    long-term changes in weather navigation the
    effect of solar radiation, tides, and impacts of
    asteroids and comets with the earth.
  • Astronomy promotes environmental awareness,
    through images taken of our fragile planet from
    space.

  • Astronomy has advanced the physical sciences by
    providing the ultimate physical laboratory - the
    universe - in which scientists encounter
    environments far more extreme than anything on
    earth. It has advanced the geological sciences by
    providing examples of planets and moons in a
    variety of environments, with a variety of
    properties.
  • Astronomical calculations have spurred the
    development of branches of mathematics such as
    trigonometry, logarithms, and calculus now they
    drive the development of computers astronomers
    use a large fraction of all the supercomputer
    time in the world.

5
  • Astronomy has led to other technological
    advances, such as low-noise radio receivers,
    detectors ranging from photographic emulsions to
    electronic cameras, and image-processing
    techniques now used routinely in medicine, remote
    sensing etc.
  • Astronomy reveals a universe which is vast,
    varied, and beautiful - the beauty of the night
    sky, the spectacle of an eclipse, the excitement
    of a black hole. Astronomy thus illustrates the
    fact that science has cultural as well as
    economic value. It has inspired artists and poets
    through the ages.
  • Astronomy harnesses curiosity, imagination, and a
    sense of shared exploration and discovery.

6
  • Astronomy provides an example of an alternative
    approach to "the scientific method" -
    observation, simulation, and theory, in contrast
    to experiment and theory.
  • Astronomy can promote rational thinking, and an
    understanding of the nature of science, through
    examples drawn from the history of science, and
    from present issues such as pseudo-science.
  • Astronomy is an enjoyable, inexpensive hobby for
    millions of people.

ASTR 1030 Exploring the Universe
The Earth is the cradle of mankind, but one
cannot stay in the cradle forever!
Tsiolkovsky

We shall not cease from exploration, and the end
of all our exploring will be to arrive where we
started and know the place for the first
time. T. S. Elliot

Astronomy vs. Astrology
Astronomy the branch of science that treats the
physics and characteristics of that part of the
universe that lies beyond the Earths atmosphere
Astrology a non-scientific system based on
superstition, that claims to explain or predict
human actions or behaviors by the study of the
celestial positions
52
MATH
Its the language of science
