Clarification

[edit source]

Perhaps this could be added... it seems some are confusing the change in the expression of the components of a tensor with the tensor itself, and thus they claim a tensor quantity changes under change of basis.

"The coordinates of the tensor change under the change of basis transforms T and S in (1). However, the tensor itself is invariant (as would be a vector)."
