Tensors for Beginners 16: Raising/Lowering Indexes (with motivation, sharp + flat operators)

Error:At 10:39, the last v~ component should have an upper k index instead of upper j index. Error: At 11:14, the kronecker delta should have a j subscript, not an i subscript. This is the last video in the Tensors for Beginners series. I'll be starting a Tensor Calculus series later in April.
