[edit] No need to apologize
Hi Joshua, and welcome here. I just came to say that you don't need to apologize as profusely as you did in your edit summary, especially since you're making a good point.
As you have probably noticed, Wikipedia can be a rather strange place with hidden customs. You seem to be doing very well, but if you ever want to ask a question, feel free to contact me. Keep up the good work! Cheers, Jitse Niesen (talk) 09:40, 3 November 2006 (UTC)

In behalf of SFC9394, might I ask that you contribute some moderation and/or content for this page. Speaking for the prior contributors, --Ancheta Wis 06:17, 6 November 2006 (UTC)
[edit] Parity
Hi Joshua, please reconsider your comments about parity. The parity operator is the operator that takes one between the disconnected components of a group (typically the two components of a rotation group). Ergo, the parity operator can never have determinant +1, since unitary/orthogonal transforms perserve the determinant, and det=+1 is the determinant of the connected component containing the identity. linas 15:18, 12 January 2007 (UTC)
