ASTR 101 (Veilleux)
HOMEWORK ASSIGNMENTS

Homework #1 (10 Points) due Tuesday February 14 (NOTE NEW DATE!)

Before starting this homework, please read Chapters 1 and 2. Be sure to try the "Quick Quiz" at the end of each chapter - this is a great way to see if you are absorbing the material. It is also an excellent way to practice for the exams, which will include some multiple choice questions eerily similar to these ones. I recommend doing this for each of the chapters as you read them and again before exams. Now you should be easily able to work the following "Short-Answer / Essay Questions" (chapter, page, and question numbers are from the book's 2nd Edition). Always put your name and section number at the top of your homework!

Extra Credit (2 Points): Go to the Astronomical Programs link on the main class web page (under Useful Links - GENERAL). Run the "Scientific Notation" program until you are sure that you can do this type of problem in your sleep (or on a midterm!). What happens when you get a problem right? Do the same for the "Working with Equations" program. If you have trouble doing either of these problems, be sure to talk to your TA about it. These are the ONLY type of math problems that I will ask you to do on a test. Print out a couple of your answers to get the extra credit.
