Starting something you couldn't finishFinnbar says: I used to know a guy who tattooed LOVE across his left knuckles, but didn't tattoo HATE on the other knuckles because he was right-handed and realised he couldn't finish. Ever run out of skills or inspiration halfway through a job?

My copy of Road to Reality has an accusatory bookmarkabout 15% of the way in. He lost me at covariant vs. contravariant tensors. It's frustrating because I can almost get it; the glimmer of understanding sparks off int he dark, but then it gutters and dies and the meaning slips away again.
You have spurred me to put this back onto my "things to read real soon" pile.

Well,They both define the transformed components as linear combinations of the original components, in the contravariant case the coefficients are the partials of the new coordinates with respect to the old, whereas in the covariant case the coefficients are the partials of the old coefficients with respect to the new.
Simples.
