PHYS 320: Mathematical Physics

Seth Major

In this course we will review, learn, and practice a number of mathematical tools which have practical use for physicists. The idea will be that these tools will be of use, not only in your remaining studies at Hamilton, but also in graduate school.

A "pedestrian guide'' to the mathematics, the course focus on the implementation of the methods and applications rather than proofs and placing the results in context within mathematics. So, even if you have had a course in one or more of the topics, the emphasis and even some of the methods will be new. I also hope that you will master much of the material so that you can easily use in research, further studies, or elsewhere in life.

The course is in lecture/discussion format punctuated by short presentations. I strongly encourage folks to ask questions and make observations. Much of the class time is spent making connections to physics. The course is somewhat unusual in that one first encounters new material in the reading and in a small number of problems. In class we focus on filling out understanding, answering questions, embellishing the material, and working through more examples.
