I don't believe that Einstein was aware of the coordinate-free
way to define vectors and tensors.

The very fact that they are tensors means that they are coordinate
indepenant, i.e. their definition does not depend on a particular
cooridinate system.
...huh?

Oh come on!

I read that as "...are coordinate dependent...". Twice. You can see
why I'd be confused.

Sorry about that :P
