Description of Class

 

This class provides an overview of astronomy, from the solar system to the structure of the universe.  This is a lab class that has an emphasis on the role of data in science.  Each semester is different, and it can be hard to predict the exact schedule.  If necessary, I will adjust the topics and schedule:

 

1.  Our Place in the Universe

2.  Telescopes and Light

3.  The Solar System

4.  Stars

5.  Our Galaxy and Cosmology

 

Warning

 

Some high school math required. Only one class of PHYS144 and PHYS133 can count toward graduation.

 

Lecture 27 available here

Lecture 33 available here

Exam Schedule

 

There will be two exams during the semester.  The first will be on Wednesday, March 19th and the second on ********.  The final is scheduled during finals week on Wednesday, May 28th at 10:30am in SHL131. An example exam for the first mid-term is here - ignore questions on chapter 5 (9,11,12,19,21,23,30,31,35)

The solutions are in the review lecture available here

The solutions for the first mid-term are here

The review lecture for the second mid-term is here

The solutions for the second mid-term are here

The final exam will cover chapters 1, 2, 3, 4, 5, 10, 11, 12, 15, 16.1 and 16.2. The final is scheduled during finals week on Wednesday, May 28th at 10:30am in SHL131.

50% of the final will be on the newer material (Chapters 12, 15, 16.1 and 16.2)

The review lecture for the final exam is here

 

Labs

 

First lab is in the week starting Feb 25th

Lab Instructors: Dana Boltuch, Nurdan Anilmas

 

Experiments play an essential role in science.  You are required to sign up for one of the PHYS133 lab sections.  You are allowed to miss one lab, or if you do them all, your lowest grade will be dropped.  Please save this for emergencies rather than attending a party.  There will not be an opportunity to make up labs. 

 

Some of the labs are computer-based and simulate the process of collecting and analyzing astronomical data.  Others will make use of our optical telescopes.  Since the latter labs depend on the weather, we cannot give a definitive schedule of labs.  It is likely that some section will be able to observe outdoors, say on a Monday, when another section, say on a Wednesday, will have to stay indoors. It may be necessary to adjust the lab grades if the different TAs prove to have different grade distributions so that no section will be at a disadvantage. 

Lab scripts are here. Download and read them before the labs.

 

  

 

Homework Assignments

 

Most of the assignments will be on the Mastering Astronomy system.  Please go to masteringastronomy.com and register for the class MAHOLDER54203.  Use your University of Delaware ID (not your social security number) as your ID number.  These assignments make use of interactive feedback and are designed to use the Socratic Method.  The computer will assign your score according to the algorithm documented on the website.  You will get a small bonus (extra credit) if you do not use the hints, but it is much better to use the hints than to guess wildly.  You will get multiple chances to answer each question, but you lose credit for each wrong answer. 

 

There will also be occasional written assignments, approximately every other week.  You should try to do all these problems by yourself., but if you get stuck, you may talk to classmates  You may not copy the solutions from someone else or have them do the problems for you.    Some assignments may ask you to work in a group, in which case you will have to state clearly what each student contributed to the assignment.

 

The honors class will be required to do additional assignments.  These will explore topics in greater depth and in particular make more use of mathematics as a tool to understand the world.

 

Requirements

 

You are expected to attend lecture and participate.

You are expected to spend a full two hours in laboratory each week.

You are required to do any preparatory reading.

The honors section is required to attend a special discussion section. Mondays 2:30-3:20pm, SHL 122  

 

Grading

 

Regular sections:

Mid-Semester Exam#1             15%

Mid-Semester Exam#2             15%

Final Exam                              25%

Laboratory                               20%

Mastering Astronomy/ Other Homework              25%

 

Honors Section:

Grade Computed as for Regular Section                       80%

Honors Assignments                                        20%

 

Letter Grades

A:    92.500 – 100.00

A-:  89.500 – 92.499

B+:  86.500 – 89.499

B :   82.500 – 86.499

B-:  79.500 – 82.499

C+:  76.500 – 79.499

C :   72.500 – 76.499

C-:  69.500 – 72.499

D+:  66.500 – 69.499

D :   62.500 – 66.499

D-:   59.500 – 62.499

F:   Below 59.500

 

Please note that I have already included the "rounding up" in this table, so if you get a 79.500 it rounds up to 80 and you will get a B-, but if you get a 79.499 you will get a C+.  There has to be a cutoff between grades somewhere.
