So this problem is from the Feynman Lectures V. 1 Ch. 27 Geometrical Optics
27–2 The focal length of a spherical surface
So I decided to entertain myself, to no avail. Does anyone else know how to solve this?
Hey guys :) I have 3 simple questions regarding Feynman Path Integrals:
1. Are Feynman Path Integrals simply another type of integral, with more steps required to calculate them? For example, is the difference between a regular path integral and a Feynman path integral analogous to a...
