The Professor:
Professor S.A. Crawshaw
Prof. S. Crawshaw (sacrawshaw@ualr.edu) is an Instructor in the Department of Physics and Astronomy at the University of Arkansas, Little Rock. He joined the Department in the Fall of 1977. He received his Masters degree in Plasma Physics in 1976. His Masters Thesis focused on the Transition from Anode Glow to No Anode Glow in a Hydrogen Glow Discharge. Prof. Crawshaw is currently Director of the Introductory Physics and Astronomy Labs

Philosophy: Examples: Using something to relate to: Spark Imagination (humor is always good medium): What I have been committed to is Demonstrating and Teaching: In the “OLD” days instructors would use “lecture demonstrations.” I still do, I will merge my lecture demonstrations and the web for the Astronomy, Elementary I and Elementary II topics covered in the labs as well as materials related to illustrate the materials.
The topics will separated into three areas: Astronomy, First Semester Physics, Second Semester Physics and a “virtual museum”.
Astronomy Topics. The items in the site are Meteorites and Retrograde Motion and there will be further topics related to what is covered in the Astronomy Lab 1101.
First Semester Physics Topics
Topics for Illustration for First Semester Physics. Including:a. Pressure. A Tall Water Manometer in the Physics Lab is the first example. This starts showing pressure equals density * g * height. As a thought catching topic a 6 cycle engine. This engine could be a good “green solution” to energy problems as well as a very good starting point for the second law of thermodynamics
Second Semester Physics’ Topics
Topics for Illustration for Second Semester Physics. Including: a. The historical origin of the convention (+charge) current b.Making an image of the moon with a 3 meter focal length mirror (which could obviously be shown in Astronomy).
The Virtual Museum This is a collection of objects that are in the Physics and Astronomy Department. Some of there are very old, rare and the origin of their acquisition for some of them is unknown. They sometimes give rise to fun explanations.

Education: M.S.,1976 Physics Department, Auburn University
Thesis: The Transistion from Anode Glow to No Anode Glow in a Hydrogen Glow Discharge B.A. 1972 Physics Department, The University of Michigan-Flint(With Great Distinction)
