PH4050 Qualitative Methods in Physics – Fall 2008

Instructor: Edward M. Nadgorny

Lecture: Tuesday, 2:00 pm, 131 Fisher

Short Description: General methods and approaches of physicists including dimensional analysis, scaling, modeling, numerical estimation, etc. as applied to the development, understanding, and solution of physics problems. Better preparation of our Physics Majors to deal with new situations will be emphasized. Discussion on Physics Logic, Philosophy, and Laws. Help with passing successfully GRE and Major Physics Test.

Course Rationale: Physicist often must address new problems in areas for which they have little or no prior experience. This course allows physics majors to examine some of the common threads between different areas of physics and apply them to thinking about, setting up, and solving physics problems using their coursework at Michigan Tech.
