• 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.

4

• 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.

The Earth is the cradle of mankind, but one
cannot stay in the cradle forever!

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

Purpose for this course

• Learn your horoscope?
• Learn about space aliens?
• Learn how to tell fortunes?
• Predict human traits or human behavior?
• Turn you into mad scientists?
• NO!

Purpose Understand our physical universe by
using science. Science imagination, logic,
critical thinking, creativity Science utilizes
observations, hypothesizing, testing
51
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

MATH
Its the language of science
