My Description: During this course we shall look up at the stars and answer the question, twinkle twinkle little star how I wonder what you are. We will also find out where to look for what in the sky and why some things are more easily seen in certain parts of the sky than others. We shall assemble a celestial sphere. Since almost everything we know about the cosmos comes from observing electromagnetic radiation (light), we shall spend some time talking and observing the properties of light. Many of these properties are outside everyday experience. We shall see how spectroscopes are used to break light apart by wavelengths and how different gases have unique light signatures (spectra) when heated. We shall assemble a spectroscope. We shall assemble a simple telescope of the same quality as Galileo use in 1610 to revolutionize our understanding of the universe. We shall assemble an ancient astronomical calculating machine called an astrolabe. With this we can predict the position in the sky of stars and the sun. We will measure the brightness and color of an open star cluster by running a computer program that is a virtual reality. We will measure the period of the orbits of the four bright moons of Jupiter by running a computer program that is a virtual reality. We will measure the orbital period of the planet Mercury by running a computer program that simulates bouncing a radio pulse sent from a radio telescope from Earth to Mercury and back. We shall see how and with what precision distances to planets, stars, galactic star clusters, globular star clusters, galaxies, metagalaxies, and super galactic clusters are determined. We shall see how color, temperature, mass, brightness, chemical composition, and age all affect stars. We shall have fun while doing this.
Clientele: Anyone who wants to understand the bigger universe outside of this planet.
Prerequisite: Willingness to read, think, and communicate.
Text:Horizons, exploring the universe by Michael A. Seeds as primary text and College Astronomy Kit by William Luzaderas the laboratory manual. The college astronomy kit includes besides a laboratory manual, a 16 power telescope (similar to the one Galileo used), a celestial sphere, and a spectrometer. You get to build and keep all of this stuff. It is real neat, especially the spectrometer. Discovering the Universe now also comes with a CD-ROM which has some videos and simulations that are not in the text. Even if you do not own a CD-ROM playing computer you may use your CD-ROM in the Math Science Learning Center at Montgomery College, Takoma Park, Science North room 101.
My Expectations:
1. That you read the assigned portions of the text before
coming to class.
2. That you will ask questions on the assigned portion
that you did not understand.
3. That you will keep your Astronomy Portfolio current
for every class.
4. That you will take a mid semester test and the one
final exam.
5. That you will appreciate our place in the universe.
Grading Policy:
1. Mid semester test March 3, 2000---25%.
2. Laboratory Reports---25%.
3. One final exam, which will be comprehensive, March
24, 2000---50%.
