This article could be improved greatly with an introduction to Spontaneous emission, the Lamb shift and the Casimir effect among other topics. John R. Brews 22:01, 3 December 2010 (UTC)

Specifying of cat1, cat2 or cat3 in the Metadata template

John, the categories specified in the Metadata template (i.e., cat1, cat2 or cat3) must be one of the workgroups such as Physics, Chemistry, Engineering, .... etc. There is no Electromagnetism workgroup so it cannot be specified as a category on the Metadata template. Therefore, I deleted it from that template.

If you click on the Citizendium logo at the upper left of this or any other page, it will take you to the Citizendium "Welcome" page ("our Home page"). The top of that page includes the titles and icons for the 6 major groups of workgroups, namely, Natural Sciences, Social Sciences, Humanities, Arts, Applied Arts and Sciences, and Recreation. Click on any one of them, and that will take you to a complete listing of all our current workgroups within those 6 major groups.

For example, Natural Sciences includes these 6 workgroups: Astronomy, Biology, Chemistry, Earth Sciences, Mathematics and Physics.

As another example, Applied Arts and Sciences includes 13 workgroups, one of which is the Engineering workgroup.

We know that the workgroups are too broad in some cases and that something needs to be done to correct that situation. Our newly elected Editorial Council will probably be tackling that subject in the near future. Be that as it may, at the moment we must live with our current workgroups.

I hope that this is helpful. Regards, Milton Beychok 05:11, 4 December 2010 (UTC)
