2. 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. ASTR 1030 - Exploring the Universe (lecture) ASTR 1031 - Observing the Universe (lab)

3. 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.

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

8. “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
