The Universe: Its Nature and History Fall 2015 Tuesday/Thursday 2:00 pm – 3:15 pm PHYS-UA 7 Meyer 122 Course Description The Universe: Its Nature and History provides an introduction to our understanding of the nature and evolution of the universe. Topics include the Big Bang Theory of the universe, present structure, and ultimate fate; the nature of stars and galaxies; white dwarfs, neutron stars and black holes; the structure and evolution of our Milky Way; galaxy clusters, the galaxy web and our place and role in the universe. We study motion and gravity, light and matter to see how astrophysicists make accurate inferences and extrapolations from data. By delving into the story of astronomy, and building the picture of our Universe outward from Earth to the Galaxy to the cosmology of the Universe you see how science contributes to the growth of human knowledge. Instructors Lecture: Dr. Andre Adler Department of Physics Office: Meyer Hall, Room 252 E-mail: andre.adler@nyu.edu Grader: Xu Li Department of Physics Office: Meyer Hall, Room 625 E-mail: xl1393@nyu.edu Prof. Adler and Mr. Li will hold office hours to assist you in the class. See NYU Classes for office hours. Required Materials Custom package consisting of: MasteringAstronomy access code with eText for The Cosmic Perspective: Stars and Galaxies 7th edition. While the course is mostly conceptual, we will do some quantitative work. Thus it is recommended you purchase a scientific calculator for use on homework and examinations. Course Grade Midterm Exam (10/22/15) Final Exam (12/22/15) Homework Assignment Prelecture Reading Questions 20% 35% 40% 5% Your total numerical score, calculated from the components listed above, correspond to the following letter grades: If your total percent score is at least: 92 90 88 82 80 78 72 70 68 60 < 60 then you will receive a grade no lower than: A A- B+ B B- C+ C C- D+ D F If you are ill and cannot take an examination, you must produce verifiable documentation from a physician, with physician’s letterhead, that explaining that you were too ill to attend the examination. Students who are absent from a test during the semester without an excuse will -1- receive a grade of zero on that test. MasteringAstronomy: Online Work will be assigned weekly using MasteringAstronomy, an online tutorial and homework system. You will access them on www.masteringastronomy.com. The MasteringAstronomy course ID for PHYS-UA 7 is MAADLER99148. You will not be able to access online work without this course ID. Important: When you register for MasteringAstronomy, 1. enter your NYU ID (the “N” number) when you are prompted to enter a Student ID and 2. enter your NYU email address. Acquaint yourself with the grading policy and due date for each assignment. A penalty for late assignments will be enforced. See Prof. Adler in office hours should you have any questions about MasteringAstronomy. There are different types problems you will encounter in MasteringAstronomy: not all are found in the textbook. Some questions will be conceptual, others quantitative, some will be multiple choice and some not; some will require a numerical answer while others will not. You must first learn how to use the system properly. To aid you in this, your first assignment is called “Introduction to MasteringAstronomy.” While it will not contribute to your grade, it is strongly recommended that you complete this assignment. Be sure to check that your browser is properly configured. You will encounter two sets of assignments for each chapter. • Prelecture Reading Questions (5% of the grade) – these assignments consist of questions you can answer correctly after reading the textbook. They will be due no later than one hour prior to many, but not all, of the lectures. This assignment is intended to help prepare you for lecture and to highlight many important ideas discussed in the text. • Homework Assignments (40% of the grade) – these consist of questions involving vocabulary, labeling, sorting, ranking, essay and numeric questions; some of them are computer graded and some will be graded by Mr. Li. In addition to the assignments and etext, it is recommended that you make use of the Study Area section of MasteringAstronomy. There you will find a number of useful tools such as • Chapter Guide • Concept Quiz • Reading Quiz • Visual Quiz • Chapter Summaries • Interactive Figures and Photos • Word Study Tools Using the Study Area is not required but highly recommended.
