# Physics & Astronomy - Courses

The Department of Physics and Astronomy offers a wide variety of courses and programs that examine and employ the laws of nature from both theoretical and applied perspectives. The courses are of value and importance to all liberally educated persons. Introductory level courses are available for students interested in any discipline, as well as for those students with specific interests in science or engineering regardless of their background or preparation. Intermediate level courses are available for students wishing to concentrate in scientific or technical fields, and a broad spectrum of advanced courses for students planning to pursue in-depth studies of physics, astronomy, engineering or related fields are provided. The department emphasizes hands-on experience and laboratory work in its programs.

## Astronomy Courses

**ASTR-1300 - The Sun and Solar System**

This course is designed primarily for students not majoring in the natural sciences or mathematics, and includes discussions of the Sun and the major constituents of the solar system (planets, comets, minor planets, meteors, etc.) as well as theories of solar system formation and the possibilities of life on other planets. Special attention will be given to the historical development of astronomical ideas and to recent developments in planetary astronomy stemming from space probe missions. Weekly laboratory experiences or telescopic observations of the Sun and planets supplement classroom work.

**ASTR-1400 - Stars and Stellar Systems**

This course is designed primarily for students not majoring in the natural sciences or mathematics who are interested in the structure and evolution of individual stars, star clusters, and galaxies. Specific topics of discussion include the endpoints of stellar evolution (white dwarfs, neutron stars, and black holes), binary star systems, x-ray astronomy, and quasars and exploding radio galaxies. A detailed investigation of the various cosmological theories describing the structure of the universe will also be made. Throughout the course careful attention will be paid to the methods used to arrive at our current level of understanding of the universe. Weekly laboratory experiences or telescopic observations of stars, star clusters, and galaxies supplement classroom work.

The laboratory exercises expose students to a variety of techniques used to study the atmosphere, hydrosphere, biosphere, and lithosphere.

**PHYS-1600 The Origins of Major Theories in Science**

The student will be introduced to major hypotheses in several different areas of natural science by reading original writings by the creators of these hypotheses. After examination of the original hypothesis in its original context and with its original implications, the student will examine the current status of this hypothesis as a central paradigm in our modern understanding of the natural world. Thus, the student will be exposed to central ideas in very different areas of our modern understanding of nature.
