Textbook: Universe, by Roger A. Freedman, Robert M. Geller,
and William J. Kaufmann III (ninth edition - ISBN 1-4292-3153-X). This
book was also used
for ASTR120
in fall 2013.
Course Description:
Welcome to Astronomy 121! After completing our survey of the Solar
System in ASTR120, we now turn our attention outward, ranging far
beyond the furthest explorations of our spaceprobes. We will learn
about the life and death of stars, massive stars, dim stars, burned-out
stars, and singularities in spacetime that destroy everything in their
paths. We will study the behavior of matter at extremely high and low
temperatures and densities. We will investigate the strange physics that
occurs at very small size scales and very large speeds. Finally, we
will explore our galaxy and others beyond it, and we will probe
what the universe looked like when it was born, how it has evolved,
and what will happen to it in the distant future. After successfully
completing ASTR120 and ASTR121 you will be a true Master of the
Universe.
Class Organization:
Lectures
meet in CSS 2428 on TuTh from 11:00am to 12:15am. Lectures led by the
professor will include discussions, worked examples on the whiteboard,
slides, videos, etc.
The Discussion Section meets in
CSS 2428 on Fridays from 1:00pm-1:50pm starting on Jan. 31. Discussion
sections are led by Teaching Assistant (TA) Marie Bernard. The section
provides a more informal environment for further developing the
material taught in class.
The Lab meets in CSS 1220 on
Mondays from 11:00am-1:00pm (section 0102) and on Mondays from
2:00pm-4:00pm (section 0101) starting on Feb. 4. Labs
are led by Teaching Assistant Marie Bernard. The Lab
allows students to explore concepts discussed in class in small
interactive groups.
The
Class Web Page is a useful resource that we will use
extensively. The website contains links to course information,
supplementary readings, and interactive programs to make ASTR121 fun
and to help you learn. You will be able to monitor your estimated
grade in the class as the semester progresses, and communicate with
other students, the TA, and the Prof. on the class blog In
addition, this site is also a gateway to many other astronomy links,
including sites with up-to-date astronomical images that are made
available to the public from telescopes in space and on the ground.
Course Expectations:
Attendance: In order to succeed in this course, I
expect you to attend all lectures, discussion
sections, and labs. This is very important! The material on the
homeworks and exams are based upon the material covered in the text
and class meetings. If you have to miss a lecture, section, or lab, be
sure to look at another student's notes and make sure that you
understand what was covered. Make sure that you understand our policy
for make-up work. See me or the TA if you have questions. There will
be times during the semester, in class meetings, when the TA or I will
ask for written responses to questions. Your written answers will
count towards your grade in the class.
Preparation: I expect you to be prepared to work.
You will understand the lecture more easily if you preview the reading
assignment. A more careful reading is recommended after lecture. You
should study your class notes sometime before the next lecture to make
sure that everything is clear. I encourage you to ask questions in
class, in section, during office hours, or over email.
Study Habits: Study wisely and ask for help if you
need it. If you just cram the night before the exam, you probably
will not do very well. It is better (and easier) if you keep up with
the material on a daily basis. Make it a point to read the chapters in
pace with the lectures; this is one of the best study habits you can
have. Taking a page or two of notes on each chapter as you read it is
also a good idea.
Grading:
I grade on a point scale with different assignments weighted as shown
in the table.
ASSIGNMENT |
Cover Sheet |
Homework |
Discussion |
Lab |
Exam I |
Exam II |
Final |
Total |
POINTS |
7 |
165 |
78 |
150 |
100 |
100 |
200 |
800 |
Letter grades will be assigned based upon your curved cumulative
score. Here is how your grade will be determined from your point
total in the class.
Letter Grade |
Course Total | Percentage |
A |
720-800 | 90%-100% |
B |
640-719 | 80%-89% |
C |
544-639 | 68%-79% |
D |
440-543 | 55%-67% |
F |
0-439 | 0%-54% |
The point scale makes it possible for everyone in the class to do
well. For example, if everyone scores above 80% in the course, you
would all receive a B- or better letter grade. I do use +/- modifiers:
you will earn a "+" if you are in roughly the upper 1/3 of students
with the same letter grade and a "-" if you are in the lower 1/3. I
may adjust the number of points required to get a given grade
depending on the class averages; however, any adjustment will make it
easier to get a given grade, never more difficult. You can monitor my
current estimate of your grade from the class webpage as the semester
progresses.
Homeworks
There are a total of eleven homeworks in this course; all will be
posted to the
Assignments link from the class website. Please type or writeup
your assignments neatly. Homeworks are due on Thursdays at
11:00am. Late homeworks will be assessed a late penalty and, if very
late, may not be accepted at all. Talk to the TA before
the due date to minimize these penalties. Graded homework
papers and solution sets will usually be distributed in the section or
lab following the due date.
Although you may discuss the homework problems with your friends,
the final writeup must be in your own words. Copying from a
friend's homework, copying from a book, or allowing a friend to copy
your homework is academic dishonesty and will not be tolerated in this
class. If you consult a reference other than the course text, please
acknowledge it in your homework - this includes websites!
Discussion
Section and Lab
A weekly hour-long discussion section (beginning Friday Jan. 31) and a
two-hour long lab (beginning Monday Feb. 3) are integral parts of this
course. Both section and lab are run by an experienced TA, Marie Bernard,
with just general guidelines from me; they will typically include a
review of lecture material, presentation of problems and material not
covered in lecture, exercises and quizzes, computer projects, hands-on
experience with instruments etc. Both section and lab serve as forums
to enhance your understanding of the course material. Your TA is an
excellent resource; get to know her and use that resource! Homeworks,
Exams, and other class work will be returned to you during either
discussion section or lab. Please attend all of these meetings. If for
some reason you have to miss a discussion section or lab, talk to Marie
before your absence and get permission from her to do
a makeup assignment. Marie maintains a website with more information
about section, lab and classwork:
Website TBD.
Exams
There will be two in-class midterm exams which are closed book with no
notes, no calculators, and no electronic devices allowed. Each exam
will consist of short answer questions, problems, and several longer
essay questions. These exams are incremental (i.e., non-cumulative)
checkups on how well you have learned the material. The schedule of lectures
included in this syllabus shows what material will be covered on each
exam. If for whatever reason, the University is officially
closed on the exam date, the exam date shifts to the next lecture
date.
According to University rules, the final exam for this course
will be held on Thursday May 15 from 8:00am to 10:00am in CSS
2428. This final exam is cumulative, that is, it will cover
all material discussed in this course. However, the
the weight on the last several chapters not covered by the
midterm exams will be higher than on earlier chapters. The
final will include short answer, essay, and problem solving questions
with the exact combination to be determined. The final exam is also
closed book with no notes, calculators, and electronic devices
allowed.
Missed Exams
If you are not able to take an exam due to illness or other legitimate
reasons (as outlined in the Academic Info section of the schedule of
classes) and you wish to take a make-up exam, you must
1) contact me by email before you miss the
regularly-scheduled exam and
2) submit a valid written excuse for
your absence within one week after the
regularly-scheduled exam.
Extra Credit
There are several ways to earn extra credit in this class:
- Attend Class: I will occasionally ask questions worth bonus points
during lectures.
- Post to the Class Blog in first month of the class.
- Do the Extra Credit questions that will be part of some
homework assignments.
- Do the Extra Credit assignments (if offered) for your
Discussion Section.
There will be no extra credit assignments besides those listed here.
ASTR121 is intended for science majors and requires a
solid high-school level science and math background. This course
satisfies the GENED requirement for a
lab natural science course. ASTR120 counts
for non-lab natural science credit.
Academic Integrity
The University of Maryland, College Park has a
nationally recognized Code of Academic Integrity, administered by the
Student Honor Council. This Code sets standards for academic
integrity at Maryland for all undergraduate and graduate students. As
a student you are responsible for upholding these standards for this
course. It is very important for you to be aware of the definitions
and consequences of cheating, fabrication, facilitation, and
plagiarism. For more information on the Code of Academic Integrity or
the Student Honor Council,
