Crookes's Radiometer
Hi,
I am doing a project regarding Crookes's Radiometer. Research on http://en.wikipedia.org/wiki/Crooke's_radiometer#Explanations_for_the_force_on_the_vanes" and a few other not-so-credible internet sources has stated that the physics behind the radiometer can be explained not only through Reynold's thermal transpiration, but also through the once refuted explanation that the molecules on the black side are faster/silver side are slower so there is a net force pushing on the black side. These articles state that Einstein found the forces resulting from differences in temperature actually do not cancel out near the edges of the radiometer vanes. However, none of the articles give any source for this.
Does anyone here know of the original paper by Einstein on this? Or even a more detailed explanation?
Also, if anyone knows of any relatively modern (post 70s or even 50s) articles regarding the radiometer, I'd really appreciate it if you'd post it here. All my research has found is a whole bunch of 1870s-1900s articles by Maxwell, Reynolds, Crookes, etc. that are horribly difficult to comprehend, full of incorrect explanations and just plain time-consuming. The only sources I have found not from that time period are A.E. Woodruff's 1966 "William Crookes and the Radiometer" as well as various books titled Kinetic theory of gases (and the stuff on the internet of course).
Does anyone know of any good modern articles on the radiometer?
Thanks,
