PCSI 701

Frontiers of Physical Sciences


J.H. Beall

The course introduces students to various questions at the frontiers of the physical sciences. Some lectures will be presented on a range of interdisciplinary topics, but the principal format of the course will be that of a graduate seminar. The assignments include readings from the current literature and some texts as well as modeling projects, class presentations, and a course project.

Fall Semester - 3 semester hours




Course Work

This course considers elements of questions at the frontiers of the physical sciences.  The work of the semester will cover selected topics of current interest from the literature at a level appropriate to the beginning graduate student. Likely topics include issues about the nature of modeling, nonlinear dynamics and chaos, modeling of biological systems, some aspects of nanotechnology and neurosciences, and topics in astrophysics and relativity.  Some lectures will be presented on these topics, but the principal format of the course will be that of a graduate seminar.

The work of the semester will consist of readings of selected papers, some work from texts, analysis of some sample data, modeling projects, and a course project based on the course topics. Papers will be taken from journals (notably  Science, Nature, the Journal of Geophysical Research, and the Astrophysical Journal, among others).  There will be some discussion of chapters of conference proceedings and texts. Students will be asked to lead discussions on the readings and engage in analysis and modeling projects related to the readings. The work of the course will be collaborative.

Grades will be determined from daily work in the seminars, presentations of journal articles and related projects, and the course project. Please provide me with a 1 page description of the course project by the 8th week of class.

Plotting and Analysis Tools:

I have no preference as to which of the many available packages you use for the modeling and analysis you do for this course.  Excel spreadsheets can be used for many aspects of the course. Some of the available packages include SPLUS, AVS, Vis-5D, XV, PV-Wave, and IDL, among many others.

I recommend, however, that you investigate IDL or PV-Wave (which are clones of one another), since they are a nice compromise betweenease of use of graphical tools and transparency of code for manipulating data..  IDL is currently installed on the cluster of machines in S&T I, Room 228.  GNU-plot is also a credible graphing tool.

The SCS license for IDL is current.

Initial Data Sets:

Three types of data sets will be described at the first class.  These will be interesting as test samples for your initial work with your chosen data analysis system.
