General Relativity 6: Contravariant vs. Covariant

Contravariant and covariant components of a vector. We continue our discussion of Gravitation and General Relativity; Still on tensors.

Finally someone explains the geometrical meaning of covariant and contravariant vectors. Thank you!

So what's the reason why in relativity appears the covariant and controvariant vectors? Because their multiplication Is a scalar invariant? Or because the Lorentz transformation stretch the ct'-x' axis?

Thank you Bhat. Is that Indian? You can email me too [e-mail]. I have a few dumb mistakes in them like dividing 6 by 2 and getting 5 so i leave them go because I avoid using notes.
