The Hodge star isn't so bad: It's just the generalization of the idea that you can describe a plane by its normal vector.

- ajkjk 8y agoOn it's own it's not bad, but it's troublesome because given a complicated expression with wedges and stars, it's not at all intuitive how you can simplify it without working in coordinates.
- cygx 8y agoIs there a silver bullet, though? The complexity of having to mess around with epsilon tensors is still there no matter which abstraction you use to sweep it under the rug...
