Because of its history and current activity, astronomy provides some excellent examples by which these questions may be considered. Fortunately, this material can be discussed with relatively familiar concepts of a non-mathematical nature. Through the study of astronomical objects we shall illustrate what constitutes truth and proof in science. Empirical results and laws result from observations. Their interpretation utilizes models and theories which have varying degrees of reliability.
All sections carry the same work load to the degree that uniformity is practical to achieve.
Be sure to attend the lecture section in which you are registered. The course content in lectures differs from section to section. Within the broad limits of the description above, each instructor has discretion over the topics covered, their relative emphasis, and the order of consideration. For each section the instructor prepares the examinations based on the lectures and other material. The lectures may contain material that is not in the reference book.
