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 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. Any student who may need an accommodation due to a disability, please make an appointment to see me. A letter from Disability Support Services authorizing your accommodations will be helpful.
Text: Discovering the Universe 5th edition by Neil Comins and William J. Kaufmann 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. You will also purchase the Janus Personal Astrolabe-Modern Edition by James Morrison. This astrolabe is the best astrolabe made in the last 400 years and is an equal to the best ancient instruments. Discovering the Universe comes with a CD-ROM which has the entire text and some videos and simulations that are not in the text. Even if you do not own a CD-ROM you may use your CD-ROM in the Math Science Learning Center, SN101 and SN102.

The CLEA, Contemporary Laboratory Exercises in Astronomy, are installed on twenty Pentium computers in the MSLC. You will have to use them in the MSLC, or copy them and run them on your own IBM compatible computer with Windows 3.1, or Windows 95 or Windows NT. You have to do and turn in to me three of these CLEA labs.
Teach each other astronomy. Teaching is the best way to learn
something. The science learning center can become your assurance
of understanding astronomy if you take advantage of it. Forming study
groups and meeting with your study group partners in the MSLC or the library
when the MSLC is closed is a good way of studying so you will pass
the exams.
Fall semester hours for the MSLC are Monday and Thursday 9A.M.—8P.M.;
Tuesday and Wednesday 9A.M.—4P.M.; Friday 9A.M.—4P.M., Saturday 9A.M.—4P.M.,
and Sunday not yet sure weather their will be hours. The telephone
number there is 240-567-1427. Where else in the world
can you get service like that except at Montgomery College.
