View source for Radio Astronomy: Tools and Techniques

This is course is aimed at
graduate students, advanced undergraduates, and interested third
parties who:
* would like to understand radio astronomy better
* would like to develop technical skills (programming, signal processing, instrumentation, algorithms, pedagogy, etc) to help them in their research
* would like to be involved, and involve their peers, in developing concrete tools to help their research

This class will follow a flexible, non-traditional format whereby each
week,  I will prepare
public-domain video "lectures" that will be
distributed to the class in advance of each meeting.
Class time will be split between discussing the subject informally,
and working in groups on laboratory projects exploring practical applications of these subjects relevant
for radio astronomy, as well as other research areas.

My hope is that this class will be moderately time-consuming, with the bulk of
the time commitment spend during class time working on labs.  All of our activities are aimed at creating tools
(both pedagogical and research-oriented) that will have value beyond
the classroom.

At the end of the semester, each student will develop one new lecture on a subject of their choice to add to this website.
