- omnicognate 11mo agoIndeed! I meant that it's good to know Wald is mathematically modern and not encrusted with coordinates. Saves me buying another book :-D (The comment I replied to mentioned both.)
- senderista 11mo agoI think it does a very good job of explaining the abstract index notation, which is superficially similar to coordinate notation but conceptually quite different.
