::I'm always on the lookout for math articles that would actually be useful to write, so let me know if there's anything that could help give background for this article -- I can write about geodesics or curvature or whatever else comes in here (these both have pages already, but they're rather silly). --[[User:MarkGall|MarkGall]] 19:51, 14 November 2009 (EST)

:::Oh, thank you so much for offering. I spent some time this afternoon thinking about the next section; it's obviously more math-intensive than the first. The subjects I'm going to have to at least ''touch on'' in order to write it are obviously curvature as a concept, parallel transport as a way to quantify curvature and the metric tensor as an extension of the Pythagorean theorem. I don't ''want'' to get into tensor contraction (the Riemann->Ricci thing) unless I have to to explain that the Einstein tensor only represents ''part'' of the curvature of spacetime, and the other part is where gravitational radiation is expected to appear.
:::Any of that sound like ripe picking for math articles? --[[User:KSorenson|KSorenson]] 20:06, 14 November 2009 (EST)
