Discussion Overview
The discussion revolves around the Feynman Lectures on Gravitation, specifically the existence and availability of the additional 11 lectures from the 1962-63 academic year that were not included in the published editions. Participants explore the historical context, publication details, and the challenges in accessing these lectures.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants note that the Feynman Lectures on Gravitation originally consisted of 27 lectures, with only 16 published, and express interest in the unpublished lectures.
- One participant questions the existence of the additional 11 lectures and seeks clarification on how this information was obtained.
- A participant cites the foreword of a new edition, explaining that only the first 11 lectures were distributed during the 1962-63 academic year, while the remaining lectures were not edited or authorized for distribution by Feynman.
- Another participant emphasizes that the first 11 lectures are considered "Feynman certified material," while the later lectures are described as "error prone," suggesting a focus on the earlier content.
- One participant shares their experience of finding a rare 1963 version of the lectures and discusses the differences between the 1963 and 1971 editions, including page counts and content.
- There is speculation about the format of the last 11 lectures, with suggestions that they may exist in handwritten or audio form.
- References to Feynman's thoughts on quantum gravity are provided, linking to various sources that may contain relevant information.
Areas of Agreement / Disagreement
Participants generally agree on the existence of the 27 lectures and the publication history, but there is uncertainty regarding the availability and content of the additional lectures, leading to multiple competing views on their status.
Contextual Notes
Limitations include the lack of access to the unpublished lectures, uncertainty about their format, and the dependence on historical publication records for understanding the content of the lectures.
