1 PHYS1118 Astronomy II Course Description: This course is designed for non-science students. A study of astronomy as related to humans and society. Topics include elements of Newtonian physics, Relativity, Quantum Mechanics, electromagnetic theory, observational and historical astronomy,and extra-solar astronomy. Laboratory work illustrates and supplements the lecture material. Prerequisites: PHYS1117 Required Text: ASTRONOMY TODAY (6th Edition), Chaisson and McMillan, 2008 Instructional Objectives (Learning Outcomes): This course is designed to give students an understanding of the universe beyond the solar syatem. An appreciation of the scientifc method and the role of experiment in understanding phenomena is developed. Students will gain an understanding of stars,the interstellar medium galaxies, life in the universe and the universe. Learning objectives include: 1. Describe how solar systems form and evolve. 2. Understand Nebular and Tidal Hypothesis and role of angular momentum. 3. Understand stellar astrophysics including star distances, motions, and luminosity and the Hertzsprung-Russell (HR) Diagram.. 4. Understand the interstellar medium including emission & absorption nebulae, interstellar gas, dust, plasma, molecules and radio emissions. 5. Appreciate star formation and clustering. 6. Describe post-main-sequence stellar evolution. 7. Examine stellar explosions and nucleosynthesis. 8. Recognize fnal evolutionary states of stars.

2 9. Cite evidence for black holes, gamma ray bursts, curved space-time, space travel near black holes Assessment: Students will be evaluated though laboratory reports and exams. The fnal grade will be based on a weighted average of the grades from the reports and exams as follows: Two Exams 30% Final Exam 25% Lab Grade 25% Report 10% Homework 10%

5 Academic Integrity Policy Statement Students and all others who work with information, ideas, texts, images, music, inventions, and other intellectual property owe their audience and sources accuracy and honesty in using, crediting, and citing sources. As a community of intellectual and professional workers, the College recognizes its responsibility for providing instruction in information literacy and academic integrity, oering models of good practice, and responding vigilantly and appropriately to infractions of academic integrity. Accordingly, academic dishonesty is prohibited in The City University of New York and at New York City College of Technology and is punishable by penalties, including failing grades, suspension, and expulsion. College Policy on Absence/Lateness A student may be absent without penalty for 10% of the number of scheduled class meetings during the semester as follows: Class Meets Allowable Absences 1 time/week 2 classes 2 times/week 3 classes 3 times/week 4 classes
