Ok, thanks for your reply, it made me go back to basics and rethink it.
I think I confused the capacity for a second order tensor to have its components represented as a matrix with the tensor ITSELF actually being a matrix. So it makes sense that the metric tensor can have its components...
I'm having a bit of trouble understanding the nature of tensors (which is pretty central to the gen rel course I'm currently taking).
I understand that the order (or rank) of a tensor is the dimensionality of the array required to describe it's components, i.e. a 0 rank tensor is a scalar, a 1...

ZnS crystalizes in the B3 type structure with the space group is F¯43m. This structure is shown below and can be regarded as the bi-atomic form of the diamond lattice (F d¯3m). Upon applying a force along the [1,1,1] direction, the crystal might experience a change in...
