Course Objectives
The course has two interlocking themes:
1. Astronomy of the solar system.
2. Science and the scientific revolution.
We will discuss what astronomers have learned about the structure of
the solar system, about the nature of planets, moons, asteroids, and comets,
and about the existence of planets around other stars. Throughout the course,
we will place just as much emphasis on how we have
learned these things as on what we have learned, i.e., on how a scientific
approach allows us to deduce the characteristics of distant objects from
observations done on the earth. The transformation from a geocentric
model of the solar system to the modern view in which the planets orbit
the sun under the influence of universal gravity is probably the single
most important development in the history of science, and we will devote
considerable attention to how it came about. Furthermore, our understanding
of the solar system rests fundamentally on our understanding of the
basic physics of atoms, light, and gravity, so we will cover these
topics as well.
Course Outline
I usually find that I can't quite get through all the material I hope
to in a 1-quarter course, but this is what I will be doing my best
to cover:
1. Motions in the Sky
2. The Scientific Revolution: Copernicus, Tycho, Kepler, Galileo, Newton
3. Matter, Light, and Telescopes
4. Earth, the Moon, and the Terrestrial Planets
5. Jupiter and the Gas Giants
6. Moons and rings
7. Asteroids and Comets
8. Formation of the Solar System
9. Extra-solar planets
10. Life in the Universe
Textbook and Lecture Notes
The textbook for the course is Universe by Roger A.
Freedman and William J. Kauffmann III, published by W.H. Freeman
and Company. I am fairly impressed by this book and think you will
find it a useful reference. However, it will definitely not
serve as a substitute for attending class and taking notes.
The current edition is the seventh, though if you bought a used
copy of an earlier edition you can probably figure out the
correspondence between my reading assignments and the sections
of the earlier edition.
I will post copies of my own lecture notes on the
course web page. I will make my best effort to get the notes
for each week posted by 6 pm on the preceding Sunday, so that you
can print them out and bring them with you to class. I cannot
absolutely promise that I will always be able to do this.
My suggestion is that you print out my lecture notes from the web
page each week, bring them with you to class, and add your own notes
to them during the lectures. The notes are, of course, only an
outline of what I cover, and they are not intended to be comprehensive
or even comprehensible on their own. The notes and the textbook
will both be useful as you review for quizzes and exams, but there
is no substitute for attending class, and if you don't attend class
you should expect to fail the course.
Course Requirements and Grading
Grades will be based on midterm exam (20%), a final exam (30%),
four quizzes (25%), and in class questions (25%).
The quizzes will take place during the first 20 minutes of
class, and the planned dates (though these might be changed) are
4/8, 4/22, 5/13, and 5/27, i.e., Friday of the 2nd, 4th, 7th,
and 9th week of class. The midterm will take the whole class
period on Friday, April 29 (5th week of class). I will explain
the "in class questions" in class. I plan to have one of these
almost every day, so failure to attend class will inevitably affect
this component of your grade (although, in practice, it will affect
other components of your grade just as much). You may not turn
in an answer to an "in class question" on behalf of anyone else;
if you do, you will get zero for this entire component (25%) of
your course grade. Further comments about grading appear on
the (separate) makeup policy handout.
Students with Disabilities
Any student who feels that s/he may need an accommodation based on the
impact of a disability should contact the instructor to discuss specific
needs. The instructor will rely on the Office of Disability Services to
verify the need for accommodation and to help develop accommodation strategies.
Students with disabilities who have not previously contacted the Office
of Disability Services are encouraged to do so, by looking at their
web site (
http://www.ods.ohio-state.edu) and calling them for
an appointment.
Academic Misconduct
OSU professors are required to report suspected cases of academic
misconduct to the Committee on Academic Misconduct. (Information
about University
rules on academic misconduct can be found on the web at
http://oaa.osu.edu/coam/faq.html.)
