Talk:Nichols radiometer

Photo/Diagram

An illustration or a photograph would be helpful here. I will attempt to locate. LorenzoB 16:37, 20 October 2007 (UTC)

Conflict in pressure of 16 mm Hg versus .05 mm Hg

The first link cited

  http://www.dartmouth.edu/~dujs/2002S/pressureoflight.pdf

claims that Nichols operated down to .05 mm Hg whereas the articly presently only considers 16 mm Hg. This is relevant in the study of this subject, where gas effects are relevant to the analysis of operation of Crookes radiometer and are supposedly ruled out by Nichols. If Nichol's works in vacuum why then shouldn't Crookes?

I'm just studyimg this topic for a week or two now so don't think I should edit the information.

Whoa what a shame

This article is extremely lacking in both references, images and descriptions. It's the job a first year physics student who's competent enough to search for references, to edit this article. One such reference is (for example): http://www.sciencedirect.com/science/article/pii/S0042207X12000723 Jahibadkaret (talk) 04:08, 29 November 2012 (UTC)

another image from their 1903 paper.

I am not an expert on copyright but I think it is public domain because it's over 70 years since publication. One of the authors was alive 70 years ago, so perhaps commons will reject this. I uploaded image moments ago, so it might take a few days to find out if it is copyvio --Guy vandegrift (talk) 06:50, 25 February 2021 (UTC)
