ERRORS:
Throughout the video, the spacing for the epsilon covectors in the diagrams is wrong. See these images for corrections: [ Ссылка ]
The spacing for epsilon1-tilde should be the length if e1-tilde amd the spacing for epsilom2-tilde should be the length of e2-tilde.
At 6:19, I have accidently labelled the covector drawings backwards. The dense one (right) should be epsilon-1 and the sparse one (left) should be epsilon-2.
At 7:53, the subscripts should be e, not epsilon.
