[edit] Represents the Sun

I agree with that fact. I read it in my Astronomy textbook. —The preceding unsigned comment was added by 67.188.172.165 (talk • contribs) .

[edit] Degrees and torsors

When one is being scientifically pedantic, there is a distinction with affine points and vectors between them. That is, there is a distinction between the temperature at which water boils, 100 °C, and the temperature difference between 50 °C and 150 °C, also written 100 °C. The same is true of points in space versus displacements and between moments in time and durations in time. It seems that historically the degree symbol tends to be used with relative values such as temperature and angles, although that usage isn't strict.

Are there any systems in which this usage is strict? That is, where 300 K + (–100 °K) = 200 K? —Ben FrantzDale 16:46, 15 January 2007 (UTC)

[edit] Degrees of arc

"In the case of degrees of arc, the degree symbol is always printed a space between it and the number." Surely not? Both International_System_of_Units#SI_writing_style and Celsius#Formatting contradict this. I've changed it. JREL (talk) 21:55, 11 May 2007 (UTC)

[edit] Mac Input

I know that as of OS X 10.4.11, the ˚ symbol can be input using ALT+K. This should be referenced. Centrisian (talk) 06:53, 3 January 2008 (UTC)
