I also, hope to enjoy learning about this stuff.

	hmmm, never put these two facts together.

	Ok, here comes one of my MAJOR beefs with the physics folk  
represented on this list AND in other venues of recent years.
	Wikipedia articles are collaborations of 'experts' in the  
appropriate fields.
	There are controversial articles that are actually 'moderated' to  
hold down the writings of certified nutcases.
	These articles are often on religious or political topics  - NOT on  
physics topics.
	The physics community needs to grow up and realize that 'we' can  
indeed work together to produce a non-judgmental, neutral point of  
view (NPoV) discussion of ANY topic related to physics.
	It's not easy, never will be.
	Worthwhile endeavors rarely ARE easy.
	But don't we owe it to the world to TRY to create non-judgmental and  
NPoV discussions of our favorite topics - so that the world can  
benefit from our collective 'wisdom'?
	My humble request is that we -

			QUIT BITCHING ABOUT PHYSICS ARTICLES IN THE WIKIPEDIA AND
				START FIXING THEM!!!!!

(I would HOPE that we could do better than the religio-politico  
nutcases in this regard.)

	ok, it's coherence vs incoherence. I think that I can appreciate  
this dichotomy.
	But, as a dedicated pedagog who wants to bring as much understanding  
as I can to the 'great unwashed' -
	must I put aside the wave/particle words when dealing with true  
beginners?
	Can't I use the analogy of
			 wave => incoherent and
			 particle => coherent
	as a warm-up exercise?
	or is there too much evil lurking in the words wave and particle for  
this to be acceptible?)
