Physics Lingo: "Strong interactions"

	*A reminder for later (to make a full article out of this): it has become clear (although in hindsight it is a tautology) that what physicists call "strong interactions" is the same as "very non-local". Namely, strong interactions correspond to forces that approach infinity much, much faster than say Coulomb's force as the distance between two particles goes to zero, mathematically, this means the interaction kernel $k(x,y)$ goes like $\|x-y\|^{-\gamma}$ for a very big positive number $\gamma$.

			By the way, this comment is directly related to the email I sent the other day about the supposed role of non-locality in particle physics ([[User:Nestor\|Nestor]] 21:02, 27 January 2012 (CST))
