Watch a Fascinating Demo of Collisions Inside a Conductor

AI Thread Summary
The discussion revolves around a demo illustrating collisions inside a conductor using marbles and nails to represent atomic positions in a lattice. Participants recall the setup where marbles slide down a board, consistently colliding with nails, which maintains their velocity. A request for a video link of this demonstration is made, with a suggestion to search for "marble electric circuit model.mpg." The conversation highlights the educational value of visualizing electron behavior in conductors. Such demonstrations effectively convey principles of conductivity and atomic interactions.

I remember seeing a demo of collisions inside a conductor. It was a long board with nails representing the atom positions (a square lattice arrangement) and you would put a hand full of marbles at the top. The marbles will slide down but since they keep hitting the nails the velocity will be constant.
Does anyone have a link to a video showing this demo?
Thanks!

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
