Please attach a proposed syllabus for this course and the Undergraduate Curriculum Course Proposal Form. DEADLINE FOR PROPOSALS: 16 September 2005 Please answer the following questions: Check Only One: This course is an existing course (in the current curriculum) that we are now proposing for this Area of Inquiry. This is a new course that we are now proposing for this Area of Inquiry. 1. Name and contact information for the department chair administrating this course. David Doughty (doughty@pcs.cnu.edu), 594-7065 2. In any given semester, how many sections of this course is your department willing to offer? Two 3. Why is this course being offered/what is it designed to achieve (Course purpose/goal)? This course is offered for two reasons. First, it is expected to be the third course in a Liberal Learning Emphasis in Physics/Astronomy for students interested in deepening their knowledge of these fields. Second, it provides a junior level introduction to quantitative Astrophysics for our majors seeking further study in Astrophysics and Cosmology. In both cases, the goal of the course is the same – that the students will be exposed to some of the deep and profound questions about our universe that can be answered using our current knowledge of Physics. Astrophysics investigates the origin and evolution of stars, the reactions which power them, the life sequence and death of these stars, the behavior of the remnants left over after star death, the formation of galaxies and the origin, evolution, structure and end of the universe as a whole. The course is intended to deepen the knowledge of these topics that students saw for the first time in their introductory astronomy/physics classes, and add a quantitative aspect to the analysis so that they can discover some of these laws for themselves. 4. All courses must address every objective listed below. Lecture Understand the process of science and the strengths and weaknesses of this process Understand that our present knowledge of the natural world is the result of the progression of scientific ideas over time Apply scientific knowledge to the definition, understanding, and evaluation of issues of contemporary society Gain an understanding of a body of knowledge in at least one natural science discipline Laboratory Engage in asking and answering questions using the scientific process Conduct analyses and evaluation of data from scientific experimentation Present results and draw conclusions in both written and oral formats Apply the scientific process to present-day questions 5. Briefly explain how this class addresses the above objectives. This is a lecture class, not a laboratory, so some of the requirements for lab classes will not be met. This class will demonstrate the process of science, the strengths and weaknesses thereof and the development of scientific ideas through progressive refinements by direct examination of the theories proposed to explain physical observations of the universe. For example, during this course, students will have several opportunities to examine the effect of gravitation on the behavior of astronomical systems. Initially, their exposure will be to the classical (Newtonian) theory of gravity, which will work well provided that conditions are not too extreme. As the semester progresses, we will discover that this theory begins to give incorrect results when gravitational interactions become strong (for example, near black holes) and the students will then explore how the explanation of gravitational interactions needs to change, leading to a discussion of Einstein's theory of General Relativity. Students will then see that the subtle changes in going from Newton to Einstein have both profound philosophical consequences for our understanding of the structure of the universe, as well as concrete effects necessary for correctly working technology here on earth (e.g. the global positioning system). In exploring our understanding of the universe, there will be many similar examples. The class will apply the scientific knowledge obtained to contemporary issues in several ways. Technology developed for the exploration of the universe has direct application terrestrially. Some of the more “exotic” theories of the universe turn out to have practical consequences – again, the global positioning system is a classic example. The goal of the class is a deeper knowledge of the field of astrophysics and the entire semester structure of lectures, individual problems, group problems, readings, etc. will be aimed at achieving this goal. Finally, even though this class is not a laboratory class, the students will get a significant exposure to the techniques used to ask valid, specific scientific questions and to formulate well suppoted quantitative answers to those questions. They will be regularly presented with open ended problems and will need to formulate plans of attack, collect background information, decide on analysis techniques, derive the necessary equations, compute their results and perform sanity checks on the computed values. 6. Course Assessment: Identify how this course will accomplish the above objectives (choose at least one). Participating in class discussion and debate Engaging in teamwork and other collaborative exercises Writing analytical or evaluative papers, perhaps incorporating original research Making oral presentations Performing laboratory experiments Conducting data analysis Participating in fieldwork Other means – please identify – Students will need to research the historical development of astrophysical theories and solve problems involving those theories, both individually and collectively. 7. Attach a proposed syllabus, which includes a statement of purpose, course objectives, and how these objectives will be accomplished. See attached. 8. If this course contributes to any of the foundations for liberal learning given below, please explain how. Oral Communication Literacy: Information Literacy: To solve many of the posed problems, students will need to search the internet, evaluate the reliability of sources found there, and run computer simulations of astrophysical events. Writing Literacy: Students will be required to submit regular, written homework assignments which will be checked for grammar, etc. 8. Explain how this course connects to Vision 2010 – the CNU Strategic Plan (www.cnu.edu/Vision2010). This class directly addresses goals I.A, I.B, I.C, and II.B by presenting a rigorous, intellectually challenging class which will require significant student initiative and responsibility. Students will need to meet class goals and deadlines. Students will also develop their critical thinking and analytical skills by solving a sequence of significant problems involving Astrophysical theory and Astronomical events. Submission Checklist: By the deadline, submit a packet with the following documents to the Assistant Dean for Liberal Learning. Please submit in electronic and hard copy form. _____ Area of Inquiry Course Proposal Form _____ Syllabus for the Course If needed: _____ Undergraduate Curriculum Committee New Course Proposal Form _____ Undergraduate Curriculum Committee Change to Existing Course Form PHYS 344 Introduction to Astrophysics Instructor: J.

Textbook: Zelik and Gregory, Introduction to Astronomy and Astrophysics Course Description Astrophysics is the study of the physical laws and processes which govern large scale interactions in the universe. It explores the formation, evolution and eventual death of stars, the sources of their energy, the structure and formation of galaxies and planets, and the birth, life and death of the universe as a whole. Clearly, the field has broad scope. This is a one semester introduction to the field of astrophysics. We will not be able to study all of the above systems in detail, instead, we will focus on three of the most broadly important and most interesting areas. We'll begin with an analysis of energy in stars, seeking to answer such questions as how stars shine, how long they can continue to do so, how they start shining, what happens when they run out of energy and how these stellar remnants (white dwarfs, neutron stars and black holes) behave. We will then move on to the study of star formation which attempts to determine how the stars got there in the first place. This study will bring in some very diverse areas of physics ranging from classical mechanics to thermodynamics to quantum mechanics. Along the way we will, almost by accident, discover how planets form. Finally, we will take a brief tour of cosmology – that branch of astrophysics which examines the universe as a whole. When working on this scale, we treat galaxies as dust and stars as insignificant – this is truly science in the large. We'll trace the development of the universe from a miniscule time after it formed, through the current state of everything and on to the eventual end of stars, time, space and life. Astrophysics is a quantitative science. Those with some background in astronomy will be familiar with many of the objects and ideas that we cover during the semester. However, this class is more analytical and will require some mathematics and computer work. Even so, this course is aimed at the interested layman rather than the professional or major in physics. This being so, we will take care to develop all the required mathematical ideas before they are needed, and we will perform analyses which are accessible to the willing student, regardless of the student's intended profession. Prerequisite Knowledge This class assumes a working knowledge of introductory physics or introductory astronomy. It also assumes that you have completed the mathematics requirement at CNU. Some familiarity with calculus is desirable but not required – we will be covering the necessary mathematics as the need arises. Structure of the Course During the semester, we will divide our class time between traditional lectures and group problem solving sessions. During the problem sessions, you will be given a single system to analyze and you will be required to perform this analysis in groups of 2 or 3 students. The results of your analysis will be submitted at the end of the class period. Written homework assignments will be assigned regularly about once every two weeks. These problems will: explore physical properties in more depth than can be covered in lecture, explore interesting phenomena that are peripheral to the central themes of the class, explore computer simulations of astrophysical events, and explore interesting historical issues that shaped the development of astrophysics and astronomy. You will have two midterm examinations. One of these will be a traditional in-class exam, the other will be a take home collaborative effort. You will have one cumulative final examination which will test your understanding of the semester material as a whole. Grading Grading will be on a Plus/Minus scale with no curve. The semester grades will be determined as follows: Percent Score Letter Grade Percent Score Letter Grade Percent Score Letter Grade Percent Score Letter Grade > 93 A 77-80 C+ 90-93 A- 73-77 C 87-90 B+ 70-73 C- 83-87 B 60-70 D 80-83 B- < 60 F Your semester grade will be determined by a combination of written homework, class participation, two midterm exams and a final exam. These individual grades will be combined with the following weights: Component Weight Homework 25.00% Class Participation 10.00% Midterm Exams 30.00% Final Exam 35.00% Academic Integrity This class is conducted under the CNU code of academic conduct. Unless otherwise instructed, you are expected to do your own independent work. All sources used in the solution of problems must be cited correctly. You are expected to follow all the instructions on homework and examination problems. Many of these problems have been solved before by others. The point of these problems is for you to discover the solution methods and learn the techniques yourself. I can look up answers as well as you can so I don't need you to do this for me. I want you to show me that you know how to solve the problem on your own. Any violation of the academic integrity policies of CNU, or the academic requirements of this class will result in a failing grade for the semester, and a letter to the Dean of Students stating that this failure was for academic integrity reasons. Disability Accommodation If you are disabled, I will be happy to provide you with necessary accommodations. By CNU policy, if you are to receive accommodations, your disability must be on file with the office of Disability Support Services. Please bring me a copy of the accommodation letter for my records.
