== Truly punctual ==

''elementary particles are truly punctual''

The above sentence appears in the Composition section with punctual pipe-linked to [[Point particle]]. I disagree with this summary of the cited source ([http://books.google.com/books?id=nRqq7Lov7IwC&pg=PA19&dq=%22What+is+an+elementary+particle%22&hl=en#v=onepage&q=%22What%20is%20an%20elementary%20particle%22&f=false]). To me the words "truly punctual" imply an infinitessimal point but that is not what the source claims. [[Point particle]] states it is an ''idealized'' concept. I think it needs a rewrite. I am no expert, but I'll start with "are closer to idealized points". Unless there are sources that show electrons have a cross-section of exactly zero - all I have found is that its size is small but still unknown. I was also under the impression that linear extent became meaningless below are certain scale. -[[User:84user|84user]] ([[User talk:84user|talk]]) 00:20, 25 February 2011 (UTC)
