Talk:Free space (electromagnetism)

The introduction to this article uses the same references as the first paragraph of the article on WP. However, it is constructed around these references differently. John R. Brews 04:16, 25 November 2010 (UTC)
 * Might I suggest a disambiguation page, since free space also is used in computer disk management and hydraulic engineering? Howard C. Berkowitz 04:22, 25 November 2010 (UTC)

The F, N, and A terms need to be defined
John, the first two equations in the "Classical case" section assume that the reader knows what F, N and A are ... and that may not be a correct assumption. I think the article would benefit from having those terms defined. Milton Beychok 06:44, 25 November 2010 (UTC)
