| Jul 18, 2013 at 4:58 | comment | added | Abhimanyu Pallavi Sudhir | @Magpie: But most people recognise the equation as the EFE immediately, and know what each term is, metric, ricci curvature, SEM tensor and so on. . | |
| Jul 18, 2013 at 1:19 | comment | added | Magpie | @Dimension10 I don't think it's deserving of a downvote either but a and b could just as easily be subscript and g R and T have not been declared so they could also be anything at all, really. It is better to write things out explicitly so that equations have meaning and the answer is more complete. | |
| Jul 17, 2013 at 19:59 | comment | added | Abhimanyu Pallavi Sudhir | @Magpie: $a$ and $b$ are obviously indices of the tensors. The downvoter clearly can't use that as an excuse. | |
| Mar 1, 2013 at 5:03 | comment | added | Magpie | Before I comment, I should mention that I didn't downvote your answer. However, I would like to point out that you have not said what a and b are (or anything else) so your full stop is premature. | |
