[edit] Merge with "Rotational invariance"?

I don't thing it is appropriate. The concepts are distinct and the names are distinct. Isotropic is a global property of a tensor field, saying that it is everywhere a scalar. For one thing, rotational invariance is more vague, e.g. one can say that f(x,y) is rotationally invariant if f(x,y) = g(x^2 + y^2) for some g. I don't think people would use "isotropic" for this. Does this make sense ? Jorge Stolfi 22:10, 7 February 2006 (UTC)

I certainly wouldn't know to look up Rotational invariance when looking for isotropic for materials questions on my university course. The seperate entry is useful. ps this is my fist Wikipedia addition :-) —Preceding unsigned comment added by 129.169.93.4 (talk • contribs)

The latter argument is ok with me. Concerning your first, you should read what the article says about "optical isotropy" (Check out the link also). [user:milk]

I've removed the notice, as the arguments favour removing it. —Pengo 22:26, 25 March 2006 (UTC)

still, it would be good to mention the connection. A tensor field is called isotropic if it is rotationally invariant at each point or in other words spherically symmetric at each point, right? --MarSch 11:23, 21 March 2007 (UTC)
