                               My homepage is here
              Office hours: After class, Tuesdays and Thursdays 3:45-4:30pm and by appointment.
                            As a general policy, I don't answer questions about an assignment or
                            test on the day it's due/given.   It's not a good way to study, and it
                            can swamp me.  I'll happily be available before due dates, though.
                            NOTE: MY OFFICE HOUR ON THU. NOV. 20 IS CANCELLED.
                            I AM AVAILABLE NOV. 19-21 BY APPOINTMENT.

                                    hours Mon 10-11am and Tue 4-5pm in the Physics Learning Center (NS 134,136).
                                    He will also run study sessions on Wednesdays 4-5pm in NS30 (basement level).
                                    I (Dr. W) will run a question and answer session (come with specific questions!) for the final exam
                                       on Wed 10 Dec, at 1:00-2:00pm, in the Natural Science Bldg, room 313 (3rd floor)
                                       Directions: from 3rd floor elevator lobby go to north wing (toward campus).
                                       It's the 3rd door on your left in the hall which has a sign with an arrow: "Labs 309-321".  There
                                       should be a Bullitt Lecture poster outside the door to that classroom.  Do NOT
                                       take the zig-zag which takes you deeper into the north wing and into the
                                       Math Dept. section of the building!
                                    John will run two review sessions for the final:
                                    Thu 11 Dec, 3:00-4:15pm, DA (Davidson) 209, math session

                                    The Learning Assistant program is sponsored by the REACH Center,
                                    which offers many tutoring services, including for math.
              Tutors:           Ms. Connie Tutwiler (A-Star), tel. 502/608-3787, e-mail catutw01*
                                    Ms. Katie Clark (A-Star), tel. 502/299-5117, e-mail kjclar05*
                                    They are available by appointment.              


              Tutoring:       REACH Center, including math tutoring in Strickler 226, tel 852-8114
                                    This course uses high school math (algebra and trigonometry).
                                    If you need help, come to the REACH center, the tutors or Dr. Williger.
                                    Many students in this course have found that they can handle the math
                                    once they get a little help.

Please note that the lab is a different course (Physics & Astronomy 108), which, if taken,
need not be during the same semester.

As usual with college courses, you are expected to spend 2-3 hours reading, doing homework, studying,
doing pre-tests, working with AceAstronomy etc. for each credit hour of the class. It's a 3 hour course,
so that means 6-9 hours outside work per week ON AVERAGE. Some people need more, some less. If you
need help,  please come to the instructor, grader, tutors, your fellow classmates, the Physics Learning Center
and/or the Reach Center.
We're all here to help. But, you need to take responsibility for yourself to seek help if you need it.

Homework - generally due on Tuesdays at the beginning of class, 8 problems/week:
Homework format:
1) no frizzy paper -- must have clean edge, not ragged from tearing out of a spiral
    notebook (this makes a mess as pieces come off, and makes papers stick together)
2) must be on standard size 8.5x11 inch paper
3) multiple pages must be stapled
4) name, due date, homework set (for example HW4) on upper right
5) use the problem numbering convention 1.7 for Chapter 1, problem 7 (so the grader and I
can easily tell which problem it is)
See
Homework policy  for more details.

I did relax the grading curve, as I said I might.  The floor for passing was lowered to 30% (random guessing
with full participation but no extra credit).    Here is the final grading scale:

I take teaching seriously, try to provide students with many ways and chances to learn
(homework, pre-tests, clickers, in-class assignments etc.) and always welcome constructive criticism.

Two big  things you can do to improve your performance: DO HOMEWORK and ATTEND CLASS
See the correlation between homework and test performance to Nov. 1
See the correlation between participation and test performance to Nov. 1
See the correlation between pre-tests (1-18) and test performance (Quizzes 1-5 and Midterms 1-2) without pre-test bonuses) to Dec. 5 Note that pre-tests and test performance do not have much correlation.



This class is CURVED.  There is no straight scale nor any relation to high school

style grading systems!
If you want to talk about your grade, please see me during office hours or make an appointment. 
UL regulations specifically forbid me from giving out grades or specific grade information by e-mail.
Since only 25% of your grade is determined, EVERYONE has a chance at a good grade (B or better).
Here is an example from our class to explain grading. 


Full participation with random guessing but no pretests or extra credit would result in an overall
average of about 30%.


Extra Credit:

The following assignments are offered every semester.  Each is worth +1% for your participation grade.

1) Attend one showing at the planetarium of  Skies Over Louisville, The Planets
(or Evening Under the Stars, if offered).  You must show your ID, register with a
planetarium staff member (signing a paper if necessary), get that staff member's name
and e-mail me within one week of seeing the show to get credit.
Keep your receipt until I confirm that you got credit.  Contact me by e-mail first
about the extra credit.  I only want to see your receipt (and have bits of paper which
can be lost) AFTER we determine by e-mail that confirmation is necessary.
The planetarium schedule is on the planetarium website (click on show schedule).

This extra credit possibility is possible to do every weekend through the
last weekend before the final exam.


2) Buy a planisphere (around $2.00-2.50, available at the UL bookstore) and take an online quiz.
The date to bring the planisphere to the planetarium is Tuesday, 30 Sep.
The online quiz is due by the end of Wednesday, 15 Oct.  (It will be loaded onto BlackBoard on 2 Oct.)

STATS:
60/128 taken, mean=3.98/5, std dev=1.15/5, range=0-5

3) Take a series of photos of sunset from the same spot with the same field of view over the
semester.  The deadline for the first picture is Tuesday, 23 Sep (extended from Thursday,
18 Sep due to Hurricane Ike).
  This is to ensure that you
take useful pictures during the semester. 
For important details, see EXTRA CREDIT DETAILS.

4) Take a photo of each of the Moon's 4 main phases (within +-3 days of each phase):  New, First
Quarter, Full, Third Quarter.  
The recommended deadline for the first picture is Tuesday, 23 Sep (extended from
Thursday, 18 Sep due to Hurricane Ike).
  This is to ensure that you take useful pictures during the semester
and don't have your only chance for a phase ruined due to clouds. If you want to start later, it's at your own risk.
For important details, see EXTRA CREDIT DETAILS.

For details of assignments 1-4, see EXTRA CREDIT DETAILS.

FOR AUTUMN 2008 SEMESTER ONLY:
5) Attend the Bullitt Lecture (link) on the evening of Oct. 29 at 7:00pm in the planetarium.
Write up a 250 word summary, typed, on paper, and turn it in.
THIS ASSIGNMENT (BULLITT LECTURE OR SUBSTITUTE LECTURES) IS POSSIBLE TO DO RIGHT UP TO THE FINAL EXAM
(EXTENDED DUE TO TECHNICAL PROBLEMS WITH ONLINE VERSION)

Prof. Caty Pilachowski of IU gave the annual Bullitt Lecture in astronomy.
Here is the PowerPoint file for it
It's worth +1% on your participation grade.
The lecture was recorded so students who couldn't make it can watch
it afterward via the Internet.  However, it is not yet available as of 15 Nov 2008.
Whenever it appears, you can watch that and summarize it for extra
credit.  An alternative online talk can be chosen from the list below. 
ALTERNATIVE LECTURES:
As of 15 Nov 2008, the online version of the Bullitt Lecture was not available.  Therefore, you
can choose ONE from these online alternatives.  As with the Bullitt Lecture, a 250 summary as
described above
is due BY THE FINAL EXAM.  Here are your alternatives, from
the UL Astronomy talk archive. Descriptions of each lecture are on the talk archive website.
