                       PREREQUISITES
The prerequisites for this course are completion of the Natural Science GE 
Foundation and math at the level of Math 1050. The math in this course will 
not go beyond understanding simple algebraic expressions with
equations and geometrical or mathematical reasoning, but not required to solve
problems except basic arithmetic (multiplication, division, square or cube). 
The concepts themselves will be challenging, and translating into equations and 
back is what you will learn during the course. The GE 
foundation pre-requisite is waived for students taking this course to satisfy 
the legacy GEL requirement (formerly Astronomy 1141). However, students should 
be aware that the material will be presented at a higher level than 
foundations courses, and they should consult with their advisor and/or the 
course instructor to ensure that they have adequate preparation for the 
course.

                       COURSE OVERVIEW
          (Detailed outline is posted on the website daily)

 Mid-Term Tests - Thursdays: Sep 12, Oct 3, Oct 31, Nov 21
 In-class quizzes - Tuesdays prior to mid-term tests: Sep 10, Oct 1, Oct
29, Nov 19 (5 qustions, 10-min duration at the end of class, reflecting 
a sample of questions to appear on the following mid-term test).

  FINAL EXAMINATION: December 6, FRIDAY, 8:00-9:45 AM
  All comprehensive final exam, 100 multiple choice questions

 N.B.: The 4 mid-term tests (35 min, 35 multiple choice questions) 
will have questions on material covered in the lectures in the 
previous ~3-week period.  Lowest test score will be dropped and 3/4 count 
towards final grade. The lectures will cover most topics in the text, but 
not all, and not always in the same order as the chapters listed above.
The lowest test score is discounted (no makeups except emergencies). 
Please keep all tests and grade sheets until the final grade. 


 Grading: 3/4 Tests = 45%, Final (100 Q's, Comprehensive) = 30%,
3/4 in-class 10-min 5-question quizzes = 10%, Fieldwork+Homework = 15%.

 Fieldwork: (i) Determine approximate proportion of distances
between planets between markers on the campus, (ii) attend 3/4                 
planetarium shows.

 Homework: (i) Compare measured inter-planetary 
distances (relative to Earth-Sun) with         
those determined by Copernicus (5%), (ii) write a 1-page, 10-point 
description of two planetarium shows (10%).

 GRADES: 1-49 = E, 50-56 = D, 57-59 = D+, 60-62 = C-, 63-71 = C,
 72-74 = C+, 75-77 = B-, 78-83 = B, 84-86 = B+, 87-89 = A-, 90-100 = A.

 COURSE GOALS and OBJECTIVES: GE Theme - Origins and Evolution

 Astronomy 2141 is a General Education Curriculum (GEC) course in 
natural sciences designed for understanding basic scientific methodology 
applied to understanding Life in the Universe.

 Understanding the theories and methods of modern astronomy,
investigating the relationship between science and technology.

 To investigate the basic facts, principles, theories and methods of
modern science as practiced in astrophysics: To learn important events in the 
history of astrophysics, to explore recent studies of extra-solar planets 
and search for life; to consider the effects of
human activity on the Earth.

 Humanity has always wondered about our place in the Universe and the 
possibility of life elsewhere - raison d'detre for astronomy as a science.
 Up to about 30 years ago only one planetary system with life
was known. Today we know of nearly 5000 planetary systems around other 
stars, many completely different than our own. The explosion of knowledge 
about possibly billions of planets around other stars has moved the question, 
(also known as Fermi's paradox): How can we be alone?

 Hitherto, speculation and science fiction is now the forefront of 
astronomical research in the 21st century.
The search for other Earths has emerged as one of the primary 
research questions driving the planning for new observatories and space 
missions. 

 Life in the Universe is an introduction to 
Astrobiology for non-science majors. The topics covered in this course lie at 
the intersections between Astronomy, Chemistry, Biology, and the Earth and 
Planetary sciences. We will learn about scientists' ongoing quest for answers 
to some of the most fundamental human questions: How did life originate on 
Earth? Is there life on other worlds? Are we alone in the universe? 
What is the long-term future of life in the universe?

The course covers three primary topics:
The emergence and nature of life on the Earth
The potential for life on other planets in our Solar System
The search for habitable worlds and life around other stars in our Galaxy.

The first half of the course will largely cover basic science concepts in the 
astronomy context. 
 
 Detailed topics, dates of quizzes, and other information will be posted 
on the daily outline.


 ACADEMIC MISCONDUCT: It is the responsibility of the Committee on Academic
Misconduct to investigate or establish procedures for the investigation of all
reported cases of student academic misconduct wherever com
mitted; illustrated by, but not limited to, cases of plagiarism and cheati
ng on exami nations. Instructors shall report all instances of alleged
misconduct to the committee (Faculty Rule 3335-5-487). For additional 
information, see the Code of Student Conduct (studentaffairs.osu.edu/pdfs/csc
12-31-07.pdf).
