Unicodify
I noticed that your bot made some recent changes to the Density of air article. It changed the unit "m3" to "m³". After looking up some references, I believe it should remain as a superscript "m3".

Wikipedia:Manual of Style says:
 * Squared and cubic metric-symbols are always expressed with a superscript exponent (5 km2, 2 cm3)

And from Wikipedia:Manual of Style (mathematics): Do not use special characters like ² for squares.

In addition I believe that a negative sign should not be changed to a hyphen. Manual_of_Style:
 * For a negative sign or subtraction operator, use a minus sign (−), input by clicking on it in the insert box beneath the edit window or by keying in  &amp;minus; ), or an en dash (see En dashes); do not use a hyphen, unless writing code.

In addition you may want to check the replacement of. Djd sd (talk) 08:11, 26 November 2007 (UTC)


 * Hi Djd, thanks for the suggestions. I'm almost sure I saw that using &amp;sup2; and &amp;sup3; was OK before, but evidently it's not now. I'll disable those transformations in my bot. Cheers, CmdrObot (talk) 20:28, 26 November 2007 (UTC)

Avtaar Gill is the name an actor. I reverted the change. Djd sd (talk) 04:39, 28 November 2007 (UTC)


 * Thanks again Djd. I've changed my bot so it'll only try to correct 'avtaar' if it's lower case. Cheers, CmdrObot (talk) 13:33, 28 November 2007 (UTC)

Newton's law of cooling
Well, I would say Newton's law of cooling is connected with conductive or convective heat transfer, because it requires heat transfer that is linear in delta-T. That's badly wrong for radiative processes, or processes with a strong radiative component. Really, only pure conduction is fully linear for heat transfer in delta-T, which is why (I suppose) this is discussed here. Perhaps we should write a little qualifier section to make this clear, as you've stumbled on the point, so also will others. Of course, the other main need for Newtonian behavior is slow internal CONDUCTION vs. the rate heat is lost from the surface of an object, but that is covered in the article. However, note that this comparison also concerns CONDUCTIVE processes only-- another reason to discuss it here. I'm open to an entire Wiki on Newtonian cooling, since it's such a peculiar process with so many things required for it to be seen. Leaving (of coure) a main article link and summary HERE.
