The exam will be 80 minutes in duration and
will be divided into two parts - a 20 item multiple choice and a 3 question long answer. Each section could contain some of the following topics:the following topics:. |
Topic One: Stars and Motion in the Heavens (Chp 2)
Things to know:
- terminology (asterism, magnitude, altitude, etc)
- how to read a magnitude-brightness graph
- how magnitudes work
- celestial sphere, celestial poles and celestial equator
- motion of Sun, Moon and planets in the sky
- precession
- how to find latitude and longitude from astronomical data
|
Topic Two: Lunar and Solar Eclipses (Chp 4)
Things to know:
- condition necessary for Lunar and Solar eclipses
- kinds of eclipses
- the Saros
- how to predict eclipses using the Saros
|
Topic Three: Historical Ideas in Astronomy (Chp 2)
Things to know:
- early ideas in Greek astronomy.
- astronomical ideas and motifs in other cultures
- Copernicus, Brahe, Kepler - their contributions
- Galileo and the "Galileo Affair" including arguments for and against Copernicanism
- how Newton changed Astronomy and our view of the universe
|
Topic Four: Gravity, Light and Matter (Chp 3)
Things to know:
- the inverse square nature of gravity
- orbits - how they work including concepts of circular and escape velocity
- tides
- Einstein's ideas on light, matter and energy
- Einstein's idea of gravity as bending of space
|
Mathematical Considerations:
You should be able to do a simple brightness-magnitude calculation and use Kepler's Third Law. Otherwise do not
worry about lot's of math - The focus of the exam is conceptual.
Formulae will be provided! |
