Water is involved in the photosynthesis. How much water are we talking about compared with the total amount on water on Earth? Is it enough to have an effect on the average age of water molecules?
@Shog9 I don't remember this meta question being dealt with... if not, could you bring it to the attention of the relevant person from SE at some point?
@David yeah, no connection to physics. Bio may like it--but remember, it doesn't have any concepts involved (unless you count the decaying to C and H mentioned by anna).
@Hakon Maybe Bio. Don't crosspost--wait a while, if he feels it necessary, David can ask a bio mod and migrate it.
Looks like mod-binding-votes are a pain at times ;-)
We're having a slight problem on chem.SE--we aren't getting many questions.
It was suggested on the meta that we ask Phy.SE and bio.SE for people willing to late-join the private beta. I can provide invites (I'll need your email address--alternatively you can send me a blank email on manishearth...
In the answers below, you'll find links to all of the questions recently imported from Theoretical Physics and Astronomy, along with the tags they had on those sites.
Imported questions retain only the tags that already exist on the destination site. Tags that do not exist may not be appropriate...
There are 391 questions in TP spreadsheet, answer ratio 1.9, so totally 1134 items should be in data dump, but indeed less than 450. Sorry for annoying
@Alexqubeat It's not annoying - I just don't know why they didn't make it yet. I'm compiling a list of missing post IDs, and will ask the dev who did the export to have a look tomorrow.
@Håkon Malmedal biology.SE does seem like the place. But if I'm the only one who thinks it's off topic, perhaps I'm wrong... just know that if we judge it off topic here, we'll try migrating it to biology. Either way, there is nothing you need to do.
