2 What is Astronomy? Story of our understanding of the Universe By the end of the course, we will have traveled through the solar system, the Galaxy, clusters of galaxies to the beginning of the Universe. Lec 01 01/19/16 slide 2

3 What is Astronomy? Story of our understanding of the Universe By the end of the course, we will have traveled through the solar system, the Galaxy, clusters of galaxies to the beginning of the Universe. Objectives Organization of the Universe Principal components that create this organization Scientific method: how we try overcome human perceptual limitations to figure this out Lec 01 01/19/16 slide 2

Attendance is optional, but you are responsible for topics covered in class whether you attend or not. My role is to help you understand. Please ask questions!! Web site: Lec 01 01/19/16 slide 8

24 Reading: Assignments in the text for each class will be given in preceding class and are required. The relevant chapters are also listed in the Syllabus by subject. You should expect to spend about 3 hours out of class for every one hour of class time. Effort = Final Grade Read: Chap 1 01/19/16 slide 9

25 Exams: Two in-class one-hour exams and a final exam. The exams will be multiple choice and short answer. 65% of total grade. The exam dates are in the syllabus. They will only change if the University is closed (e.g. snow day). In that case, the exam will be held at the next class meeting. Format: combination of multiple choice and short answer questions. Makeup exam policy: Following the University guidelines, makeup exams will be given only for documented medical or family emergencies or by prior arrangement. Read: Chap 1 01/19/16 slide 10

26 Homework: There will be (roughly) weekly homework assignments worth 25% of the total lecture score. We will using an online assignment system. Read: Chap 1 01/19/16 slide 11

27 Homework: There will be (roughly) weekly homework assignments worth 25% of the total lecture score. We will using an online assignment system. Special-topic reports: Choose three topics of interest to you (approx words). Due by end of February (1), end of March (2) and end of April (3). Worth 10% of the total score. See web site for suggested list of topics. Confirm others with me. Read: Chap 1 01/19/16 slide 11

28 Extra credit: At the end of each class, you may pass in a sheet of paper with your name, UMass ID and 1. Brief description of an idea or topic from the day that you found particular interesting 2. Your top question from the day s class Over the entire semester, this is worth up to 5% to your final score. Some of the homework assignments will have additional questions that count for extra credit. There are no other forms of extra credit. Read: Chap 1 01/19/16 slide 12

29 will be assigned on a modified straight scale. Scores will be adjusted upward if the exam is too hard. 92.5% A 90% A- 87.5% B+ 82.5% B 80% B- 77.5% C+ 72.5% C 70% C 67.5% D+ 60% D 3 exams 65% Online homework 25% In-class feedback 5% Topical reports 10% Academic Honesty is expected of all scientists, and also of all students of science. Read: Chap 1 01/19/16 slide 13

30 Interactive, online homework and study system (see your handout) You must register using the access packet that comes with your textbook Buying a used book is perfectly OK; need to purchase access on line for $61.00 Can purchase e-text and for $96 Read: Chap 1 01/19/16 slide 14

31 Read: Chap 1 01/19/16 slide 14

32 : grading The assignments untimed. You may stop in the middle, go back later, etc. The system offers you hints, if you want them. Not using hints is worth 2% bonus credit. If you give an incorrect response, in many cases, you will get some extra help from the system and you can try again. However, every time you answer incorrectly, you lose 20% of the available credit for that problem. Assignments submitted before the due date, of course, get full credit. For every day an assignment is late, you lose 3.5%. So after approximately two weeks, you will have lost 50%. Assignments that are more than two weeks late receive at most 1/2 credit.

35 Scientific Notation The numbers encountered in this class are astronomical: The nearest star is 41,000,000,000,000 kilometers away The mass of the sun is 2,000,000,000,000,000,000,000,000,000,000,000 grams Scientists have devised a more compact notation for dealing with such numbers called scientific notation. Read: Chap 1 01/19/16 slide 18

36 Scientific Notation 41,000,000,000,000 kilometers 2,000,000,000,000,000,000,000,000,000,000,000 grams There are really only two important parts to each of the numbers: 1. The leading digits which establish the precision of the number itself 2. The number of digits which sets the size or magnitude of the number In Scientific notation: and Read: Chap 1 01/19/16 slide 19

37 Scientific Notation The is, as it appears, a multiplication: 10 2 = = = = 1, = = 10, = = 100, = = 1,000,000 so = = 45,000. Read: Chap 1 01/19/16 slide 20

38 Scientific Notation Counting zeros and moving the decimal place is a convenient way of carrying out the multiplication by powers of ten Example: Want: = = 10 8 The result of that long string of multiplication is that we add the exponents of the 10 s: = 8 Read: Chap 1 01/19/16 slide 21
