The Feynman Lectures Original Course Handouts

Richard Feynman and students enjoying "Coffee Hour" at Winett Student Center, Caltech, 1964. Dennis Oberg is the tall student with the big smile.

About the FLP Original Course Handouts

The Feynman Lectures on Physics was based on a two-year introductory physics course that Richard Feynman taught at Caltech from 1961 to 1963; it was published in three volumes during the years 1963 to 1965, and used as the introductory physics textbook at Caltech for nearly two decades. However, Feynman's original students had no textbook, and their only written guidance came from materials that were created "on the fly" by Robert Leighton, Matthew Sands, graduate students, and others. They were mimeographed and handed out in recitation sections and labs. These materials included lecture summaries and outlines, lab guidelines, descriptions of experiments, homework assignments, exams, and quizzes. Among Feynman's students was Dennis Oberg, who kept his course handouts all these many years, and generously allowed The Feynman Lectures Website to copy them so that we can present them here, with Caltech's permission, as historical documentation of Feynman's original undergraduate physics course.

The FLP Original Course Handouts Viewer

To facilitate online viewing, the original course handouts have been converted to a deep-zoomable format. They are served by a Cantaloupe IIIF image server, and displayed using OpenSeadragon image viewing software. The photos are presented in an "image viewer" application with a simple tabbed user interface designed to aid in their organization and study For detailed instructions on using The FLP Original Course Handouts Viewer please refer to its "Help" tab after opening the application with the link above.
