ASTR 201 (Cosmology)
course description
"When you change the way you look at things, the things you look at change."
Overview
: ASTR 201 is a three credit, general education course at the Tier II level intended for those students with no university-level background in science and mathematics. We will focus on understanding (not memorizing) the physical processes at work in the Universe, developing the ability to solve problems, improving confidence and skill in quantitative expression, and building an awareness of how science influences daily life. In Tuesday/Thursday classes interactive "lectures" will concentrate on major discoveries and new perspectives of our Universe. Classes will emphasize hands-on measurement and observational skills related to the concepts presented in classes that week. These "labs" will help develop problem-solving skills.To Succeed:
To be most successful, each student should set a personal goal and
Textbooks:
There are two textbooks for this course. Both books are available in the University Bookstore. The first is "A Briefer History of Time" written
by Stephen Hawking and Leonard Mlodinow. Stephen Hawking is a famous scientist working to understand the Universe and black holes. Since 1988, his books
have been best-sellers.
The second book is "The Cosmic Perspective: Stars, Galaxies, and Cosmology" (5th edition) written by Drs. J. Bennett, M. Donahue, N. Schneider, & M. Voit.
This book is simply the second-half of their larger edition ("The Cosmic Perspective") that you may have used in a previous NATS course.
At the end of each chapter are sections entitled The Big Picture, Summary of Key Concepts, Review Questions, Discussion Questions, and Problems. I encourage
you to spend time in these sections to help test and develop your understanding and to prepare for the examinations.
Author's Web Site:
You are required to enroll in the authors’ interactive Web site called “Mastering Astronomy” (http://www.masteringastronomy.com). There you
will find supplementary materials like movies, graphics, etc. and you can also practice problems, view tutorials, take self-quizzes, etc. Please follow these directions carefully:
Classroom:
T/Th 9:30-10:45 AM in room 140 of the Integrated Learning Center. There may be occasional exceptions to be announced beforehand in
class and on the Class Web Page. Lectures will begin at 9:30 am sharp on regularly scheduled class
days. If you arrive late, please enter the classroom quietly but feel free to come up front for a good seat. Please do not bring food or drinks into the auditorium.
Professor:
I am your professor, Dr. Don McCarthy - an
Astronomer at Steward Observatory, the research arm of the Department of Astronomy. I
enjoy two main types of athletics: Throwing almost anything (javelin, snowballs, softball,
skipping rocks, ...) and endurance events (marathons, long distance cycling). Teaching Assistant:
I am your graduate TA, Ms. Amy Stutz -- an astronomy graduate student. I am
studying the dark clouds where stars are born. One of the questions I look
at is how these clouds collapse: do they have turbulence and magnetic
fields, and what are their relative strengths? Are these forces enough to
support against the force of gravity? I mainly use data from Spitzer
Space Telescope, a space-based infrared telescope. I also use longer
wavelength radio data for my project. When I am not working, I like to
practice my Spanish (I grew up in Spain); I also like watching movies.
Please(!) do not hesitate to contact me at any time.
Preceptors:
Preceptors are highly-motivated students who wish to help teach their peers
under the supervision of the course instructor. Often students learn best from
other students and preceptors can really "make a difference."
As a preceptor in this course you would take an active role in the teaching process by working
directly with Dr. McCarthy. You would also receive University credit by enrolling
in UNVR 197a and completing several workshops with
other University preceptors
to learn and practice skills in effective teaching.
If you would like to become a preceptor, please contact Dr. McCarthy and
also learn about the Teaching Teams Program.
Communication:
PLEASE! let me know if you have any disabilities which might make it difficult
for you to hear, see, take notes, or understand course material. Students who are
registered with the Disability Resource Center must submit appropriate documentation
to the instructor if they are requesting reasonable accommodations:
http://drc.arizona.edu/instructor/syllabus-statement.shtml. Classes and examinations will be conducted
in English. Students are expected to write clear sentences and paragraphs using
good English for reports and exam questions. Always proofread your work before
submitting it! A bulletin board in the hallway near my
office will post the course syllabus, any recent announcements, sign-up sheets,
test results, and astronomical event notices. Your Star Name:
You have been assigned a star or constellation name as your code name for all
assignments, exams, the optional project, and grade distribution. NEVER
WRITE YOUR PERSONAL NAME OR STUDENT ID NUMBER ON ANY ASSIGNMENTS IN
THIS COURSE; USE YOUR CODE NAME INSTEAD!! Academic
Integrity:
Dr. McCarthy and the Department of
Astronomy adhere to the University's Code of Academic Integrity. It
is expected that each student will do his/her own work on all exams, homework,
labs, and projects. Even if you are part of a team solution to a problem, you
must use your own wording and ideas in summarizing the solution and expressing
conclusions. You may start an assignment in a team. However, once you decide HOW to approach a problem,
you must then make all your own measurements and use your own wording to interpret and
express conclusions. Any assignments that appear identical will be awarded "zero"
points and can lead to expulsion from the class and the University. At a minimum such
violations of the Code will lead to an Academic Integrity investigation with the Dean
of Students Office.
During my years of teaching, I have
developed skills in recognizing plagiarism and outright cheating. Such
violations of the Code can be penalized by expulsion from the University and
negative reports in your official records. If you are having difficulty in this
course, PLEASE just ask for help instead of sacrificing your future. TurnItIn.com:
If you decide to take and continue in this course, you may be instructed to submit your papers online to a plagiarism-prevention
program called TurnItIn.com. When you set up your individual account with TurnItIn.com for this class, make sure you understand and
consent to all the terms that the program provides you at that point.
You should note that TurnItIn.com – always without your name and any personal information – will retain your paper as part of their
database so that students who plagiarize from it can be detected. Because of this program, the vast majority of you who do your own work
and cite your sources of information properly will not have to compete with students who commit undetected plagiarism. Anyone who has
questions or problems with TurnItIn.com may talk privately about these with the instructor.
Lectures:
Interactive "lectures" will concentrate on major discoveries and new perspectives of our Universe.
Classes will emphasize hands-on measurement and observational skills related to the concepts presented
in classes that week. This “follow the evidence” approach will help develop problem-solving skills and
reinforce understanding of the scientific method.
Lecture material will supplement and expand upon the required reading using PowerPoint, digital animations,
videotapes, music, laboratory equipment, and liquid nitrogen as teaching tools. Impromptu quizzes will be
given to promote understanding, self-assessment, attention, and attendance.
Lecture notes: The text of each lecture is given below in outline form ahead of class. You must attend class to
experience the associated images, graphs, animations, videos, and demonstrations.This
convenience is provided so you can THINK about the material instead of mindlessly
writing your own notes. Please print them out and bring to class so you can add your own thoughts as the lecture proceeds.
Absence policy:
You are required to attend each class in accordance with University
policy. Each lecture will
build on the previous one. Therefore, if you miss class, you can get behind so
quickly that it may be very difficult to catch up and you might also miss impromptu
quizzes.
All holidays
observed by organized religions will be honored for those students who show
affiliation with that particular religion. All absences pre-approved by the Dean of
Students will also be accepted.
Behavior:
Dr. McCarthy promises to be respectful of all students. I hope you will do the same in
accordance with the Student Code of Conduct
and other University
guidelines.
Homeworks & quizzes:
Weekly homework assignments are a major component (45%) of this course. They are designed to involve each
student in wrestling with the concepts presented in lectures and the textbooks. These assignments will
also reinforce and apply concepts discussed in class. A few quizzes will be given during
class. At the end of the semester the average score of the quizzes will be equivalent to an additional homework
assignment.
“Reaction Paper” essays are meant to engage you in specific topics and to enable you to express your
opinions and interpretations once you understand the particular concept. These essays
will be graded according to the rubric used in the Writing Program of the Dept. of English: Content (50%),
Organization (20%), Expression (20%), Mechanics (10%).
Homework is due at
the start of class on the specified date. Electronic submissions are
not accepted. If an assignment is turned in late, a late-penalty of 10% will be assessed for
each class period that has elapsed since the due date. Assignments will not be accepted after Thursday of the
following week.
The following rules
apply to homework assignments:
1. All homework must be typewritten. Math symbols and calculations
may be handwritten but must be legible.
2.You must always show or explain how you reached a solution by recording intermediate steps
in a calculation or describing your solution logically in words.
3. Some problems only require your opinion to be clearly stated. In these cases, your grade will be determined more
by your reasoning and writing abilities than by the exact answer.
4. You may START an assignment in a team. However, after deciding HOW to approach a problem, you must then
make all your own measurements and always use your own wording to interpret and express conclusions.
Homework solutions that appear identical are a violation of the Code of
Academic Integrity and will receive a grade of zero plus potential expulsion from the course.
Study sessions: Dr. McCarthy will conduct optional homework study sessions each
Tuesday afternoon from 2-4 PM in room 550. To participate, you must have already attempted all the problems
or activities. Students may be asked to help each other and to lead discussion.
On Wednesday evenings (9-10 PM) Dr. McCarthy is available online via AOL
Instant Messenger. His screen name is “mccarthdw”.
Grading
:
Students have two options for determining the calculation of grades, one of which requires a
significant project to be completed with the approval of the instructor. You must choose
the option best for you by February 29. Grades will be derived from the following
categories with the indicated percentage weights.
OPTION #1:
OPTION #2:
“Participation” includes attending class regularly, asking relevant questions during
class, seeking help during study sessions and office hours, helping to lead discussions, etc.
Final course grades will be assigned as follows: A (90-100%); B (80-89%); C (70-79%); D (60-69%); E (<60%).
"Resurrection Points":
In this course students can recover (i.e., resurrect) points lost on previous exams and
can earn a 100% grade on the Exam component of this course until the very last day of class.
Dr. McCarthy does not grade on a curve so
that each person can earn an "A" by demonstrating understanding of
the scientific concepts presented and illustrated in class. Therefore, you will
not be competing against your classmates for exam grades. "Resurrection points" encourage
you to master all the major concepts taught and demonstrated in this course,
even if it requires the whole semester, and even if you perform poorly on the
first two exams. I recognize that people learn at different speeds and that
scientific concepts are often not intuitive, requiring extra time and effort to
understand. You can "resurrect" points you
may have lost on an early exam by demonstrating correct understanding of the
same concept on the next exam. For example, if you missed 3 of 5 questions relating to the concept
of "gravity" on the first exam, you can "resurrect" points by correctly answering 4 of 5, or 5 of 5, questions in
a similar section on the second exam or on the final exam. You cannot lose points in this process.
I encourage you to master the
scientific concepts as early as possible. By waiting until the end of the
semester to understand them, you will be placing unnecessary stress on yourself
and increasing your likelihood of failure. Examinations:
There will be two in-class exams (Feb. 21; April 3) and a final exam (May 13, 8-10 am). The
two-hour final exam will emphasize the final
third of the course and provide "Resurrection Points" for students to earn back points
lost in previous exams. The format of all exams will include multiple choice and
short essay questions. An informal review session will be
held one or more days ahead of each exam to provide you an opportunity to ask
questions and to practice concepts presented during the course. Sample exams
from past courses are available at the same locations as the lecture notes as
listed above. ALL exams will be OPEN-BOOK and OPEN-NOTES.
Exams will emphasize UNDERSTANDING INSTEAD of memorization. Bring your
UofA CAT Card and a #2 PENCIL to all exams! There will be NO makeup exams except
in cases of extreme difficulty such as a proven illness.
For my
research I build cameras and spectrometers to capture the infrared light emitted by newborn
stars, extra-solar planets, active galaxies, and "minor planets" in our solar system. This
equipment is used on large ground-based telescopes and in space telescopes like the Hubble and
future James Webb Space Telescope (JWST). My work often involves the use of interferometry and
adaptive objects to provide very sharp images despite atmospheric blurring. I enjoy teaching a
lot and serve as Director of
Astronomy Camp and the education program for
JWST/NIRCam.
