Above all else

So according to some people, the Archbishop of the Catholic Church is not allowed to tell his own flock not to attend a concert in which bikini clad nuns gyrate around crucifix stripper poles.  Seriously.  Are these people even hearing themselves as they say this?

And I want to go further than this.  Some people will say, reading this, that well, I guess it's OK if the Archbishop is only talking to his own

Happy Chinese New Year! As we were having lunch earlier, my daughter was asking me whether I knew anything about covalent bonding.  The words struck a deep, long-forgotten  memory somewhere in the cerebellum, and I asked if what she meant was the situation where one atom has "extra" electrons and binds with another atom that is "short" of an electron (my old Chemistry teacher is probably foaming at the mouth about now). So my daughter said, no, I think what you're referring to is ionic bonding, like when two copper atoms ("short" of 4 electrons) bind with the "sulphate" polyatom ("extra" 4 electrons). Covalent bonding is like, when, a hydrogen atom, which has one electron, but remains "short" of one electron, binds with another hydrogen atom, and the two hydrogen atoms sort of "share" each of their lone electrons with each other, such that both atoms now have the full complement of 2 electrons (Chemistr
