Course Description

 

An Introductory survey course to develop an appreciation of contemporary astronomy. Topics include the solar system, stars and stellar evolution, the milky way galaxy, and cosmology.

 

Course Objectives

 

The goals of this course are
- to understand science as a process: how it is done, what skills are involved, how it applies to everyday life, and how it is used to learn about the universe
- to understand and apply basics physics concepts to problems in astronomy

By the end of this course, students should be able to:

  • understand important concepts in astronomy
  • apply scientific thinking to problems in astronomy
  • apply scientific thinking to problems in areas other than astronomy
  • understand the nature of light - how it interacts with matter and how we get information from it
  • understand the nature of gravity
  • understand the observational foundations of some of astronomy's greatest discoveries

None.

 

The Goal of The Course :

The goal of this course is to give the Liberal Arts and Science students a clear and descriptive introduction to Astronomy using simple mathematics. I do want you to enjoy astronomy.

 

Attendance Requirements :

Responsibility to Add, Drop or Withdraw.

It is the Students responsibility to drop all classes in which he/she is no longer attending. Absence in an On Line course means lack of work on the Quizzes and Exams in a timely fashion. Withdraw after the deadline will not be approved without proof of circumstances beyond the students control which made him/her unable to meet the deadline.
