Catalogue Note
A NICE EXAMPLE OF FEYNMAN'S QUICK SKETCHWORK OF CALCULATIONAL DETAILS. Here, a classic Feynman mix of algebraic, trigonometric, and graphical elements. In center, on verso, 3 diagrams labeled as such, accompanied by their statistical weights- 6,12,2 which multiply their quadratic contributions.
