Описание: replacement video for grss027, which contained a logical error. Sorry it's taken me so long to getting round to sorting this out. This video shows that the metric tensor g with upstairs indices is the matrix inverse of the metric tensor with downstairs indices. I have lost the AE file for the ident, which is why the video starts with a hand-drawn knot, sorry about that. And thanks to Eamon Concannon for pointing out the error, and providing a correct derivation. Best wishes, TT
