The Natural Science courses at York University are designed for students who are not intending to become professionally involved in science.  However, science is a part of everyone's day to day life, and as such, it is important to become familiar to a certain extent with the scientific method and outlook and to be cognizant of some of the achievements of scientific thought.  The various NATS courses offer the opportunity to investigate the scientific process in a non-technical but nevertheless thought-provoking manner.

 

Natural Science 1740 6.0, Astronomy, discusses one of the oldest sciences.  In the course, topics ranging from the origin and structure of our planet through to the evolution of the stars in the night sky and the overall structure of the Universe will be studied.  The historical development of astronomical concepts as well as the latest results from ground and space observatories will be discussed.  Topical subjects like the disappearance of the dinosaurs, brown dwarfs, black holes, dark matter, the Great Attractor, and the Big Bang are included.  With the assistance of Planetarium demonstrations and telescope observing nights, it is hoped that all students will gain familiarity with the stars in the night sky.  The course will make extensive use of audio-visual presentations and computer software.  The course is not taught at an advanced mathematical level.  High school mathematics up to the level of Grade 11 (basic principles of geometry and algebra, but not calculus) is all that is necessary.  Assistance with mathematical manipulations is provided in all laboratory periods.

 

In short, the science of Astronomy will transport you back to the beginnings of civilization and then forward to contemplate the ultimate future of the Universe.  Not all answers are known and the ongoing need for research will become evident.  In essence, astronomy is the study of all that is.  As with most areas of human knowledge, the more you know, the more fascinating a subject becomes.  The course lecturers, the Teaching Assistants and the staff of the York Astronomical Observatory will all endeavor to share with you the joys and excitement of modern astronomy!  Enjoy.

Outline of Lecture Course  (guide only)

 

First Term

 

Week 1 & 2:

Motions in the sky – what do we see without a telescope? What are the common objects we see and how do these motions occur. Where do things like the zodiac come from?

 

Week 3 & 4

History of Astronomy – From the Blanchard Bone to Einstein. How long have we been making astronomical observations? How did ancient cultures see the skies? How did the Greeks see the universe? How did modern astronomers learn about how the heavens work?

 

Week 5

Kepler, Newton and Einstein – how did the works of these individuals allow us to explain how the universe works?

 

Week 6 

Light, Telescopes and Space Probes – How we do the science of astronomy, learning at a distance. How we use light to figure out about the objects in the sky. How telescopes work. What kind of space probes have we sent out to explore the universe

 

Week 7

Earth – the template for a planet. What makes up the planet Earth?

 

Week 8

The Inner Planets – Mercury, Venus and Mars. This will look at the features of these worlds, how they compare to Earth and some of the missions to explore them

 

Week 9

The Outer Planets – Jupiter, Saturn, Neptune, Uranus. The outer gas giants. How they differ from the inner rocky worlds. What missions have gone to the outer solar system?

 

Week 10

Other objects in our solar system – asteroids, comets the Oort cloud, and the Kuiper belt. What happens when these objects interact with Earth? What happened to the dinosaurs, what happened in Siberia in the early 20th century?

 

Week 11

Extrasolar planets.  What are the planets around other stars like and what are we doing to find them?

 

Week 12

Extraterrestrial Life – What is out there? What are the conditions for life? What are we doing to search for life and where do we think we might find it?

 

Second term

 

1.       The Solar System (1 week)

{-} Formation and evolution of the solar system.

 

2.       The Stars (3 weeks)

{-} The Sun, an average star close-up.

{-} Measurements of fundamental properties.

{-} Atmospheres, interiors, and the source of power.

 

3.       Star Systems and Stellar Aging (3 weeks)

{-} Multiple stars, Star clusters.

{-} Stellar birth and death and the theory of stellar evolution.

{-} The story of Supernova Shelton, 1987A.

 

 

4.       The Milky Way (2 weeks)

{-} Stellar, interstellar, and dark components.

{-} The size, shape, composition, and structure.

{-} Activity and evolution.

 

5.       The Realm of the Nebulae - Galaxies (2 weeks)

{-} The types and properties of galaxies.

{-} The extragalactic distance scale and the distribution of galaxies in the Universe.

{-} Quasars, Seyferts, jets, and other exotic extragalactic objects.

 

6.       Cosmology and Cosmogony (l week)

{-} The size, age and expansion of the Universe.

{-} Current theories on the structure, evolution, and formation of the Universe.

{-} The possibilities and options for life in the universe.

 

Format of the course and term work

 

There will be three one hour lectures given each week for this course on Monday, Wednesday, and Friday mornings at 1630 hrs in Computer Science & Engineering Lecture Hall A (CSEB – A).   In addition, each student must attend a two-hour laboratory period every second week, during which an exercise must be completed.  Two of these assignments will be computer (PC) based.   (There are a total of 8 such exercises in the two terms.)

 

Attendance at the lectures is highly recommended, because the professors greatly enhance the material covered in the textbook.  (Also, refer below with respect to the video/reading quizzes.)  Attendance will be taken during the laboratory periods.

 

The breakdown for the course assessment is as follows:

 

Laboratory exercises (8)             20%

Video quizzes                            5%

Fall term exam (December)         27.5%

Winter term exam (April) 27.5%

Fall Term project                        10%

Winter Term project                    10%

Total                                        100%

 

Throughout the year several video presentations will be given to further enhance the lecture material.  Astronomy is a very visually appealing course and as such, lends itself to the video format.  To ensure that this material is viewed by as many as possible, questionnaires concerning the video will be handed out in class to be completed by the student during the video.  The completed material will constitute a portion of the final grade.  (These are VERY easy marks.)  Missed quizzes video will be assessed as zero marks.  No make up video sessions will be available but as each video is worth 1% and more than 5 will be given, only the best 5 videos results will count.  Further, it will greatly enhance the learning process if you read the relevant chapter in the textbook before you come to class. 

 

The term projects will require some independent research and involve some outside work under the stars.  The projects will be due near the ends of each term.  Because of the considerable time allowed for the term project (approximately 2 months), the deadline for submission will be adhered to strictly.  Sessions at bight will be arranged with the Teaching Assistants to further assist in the completion of these projects.  These sessions will be held on campus.  Completion of the laboratory work and the term project will significantly enhance a student's overall mark.  You are strongly encouraged to complete this work to the very best of your ability.

 

Note that the University will set the examination schedules.  The material in the exams will be set by the term lecturer upon work presented in class and from the textbook.  It is the student's responsibility to be available to take the exams during the examination periods.

 

Textbook

 

The textbook for the course is 21st Century Astronomy by Jeff Hester, et al., W.W. Norton & Company, New York London 2002.  It is available from the campus bookstore.  Material covered during the lectures will often be referenced in this book.  Approximately chapters 1 through 14 will be dealt with in first term while chapters 15 through 28 will be covered in the second term (approximately).  An additional mandatory set of lab exercises and term projects will be available from the bookstore early in the Fall term.

 

A Note Concerning Plagiarism

 

Any material submitted by a student for this course must be original unless otherwise acknowledged.  Collaboration with colleagues on a problem is an essential part of science, but to claim credit for work performed by others is both unethical and unacceptable.  Plagiarism and cheating will not be tolerated.  The penalty for such offences range from a failing grade on the submitted material to expulsion from the University.
