This section contains the lecture notes which serve two purposes: to guide the lecture topics and to serve as the required course readings. Many of the lecture notes have 1.63J/2.21J listed as the course number. This is the new course number as of Spring 2004, when the course will be offered as a joint course with the Mechanical Engineering Department, as part of an iCampus school-wide modular program on fluid mechanics at MIT.
