In the first volume of his lectures (cap. 65) Feynman asserts that these 2 can be the PDF of velocity and position of a particle.
Under which conditions it's possible to model velocity and position of a particle using these particular PDFs ?
ps: Is the "Heisenberg uncertainty principle" applied only in the study of electrons and smaller particles ?
pps: Feynman also asserts that the [itex]\Delta x[/itex] and the [itex]\Delta v[/itex] in the "Heisenberg uncertainty principle" formula are two variances. Is this correct and accurate ?
