Talk:Reflection (mathematics)
From Wikipedia, the free encyclopedia
reflection (also spelt(also spelled 'spelled') reflexion)? :)
This article does not contain information for the novice (me). Anyone want to translate into non-technical english?Hyacinth 23:37, 22 Dec 2003 (UTC)
[edit] Curious
Reflection is everywhere in the universe but a simple logical discussion is necessary for me to work on P vs. NP.
Would anybody know of a book I can buy or look at in a library?
My theory:
Look at your hands. They both have fingers. They both have the ability to pick up objects. They both have the ability to snap their fingers. They DO NOT have the ability to interchange. That would mean your left hand and your right hand could be exchanged but for all *practical* purposes they would be backwards.
Now you have the concept for my theorom:
That P != NP for all cases But for NP Complete cases you coulds see true interchangeability.
Whew! I have a theory so please be kind and email me if you have any thoughts or ideas..

[edit] Fixing this article
I always thought that I knew what reflection is about, but after reading this article I am more confused than before. I think it needs a rewrite. In particular, looking at this diff, it looks to me that the old version is better than what we have in here. It is not as rigurous, but does a better job of explaining the essense of the thing without going into too many specifics. Comments? Oleg Alexandrov (talk) 00:21, 20 October 2005 (UTC)
- What's wrong with going into specifics? Giving the formulas for reflections makes precise what is stated in the introduction. -- Fropuff 00:28, 20 October 2005 (UTC)
- I don't refer to the formulas section, rather to the section right before. Sorry for not being specific. Oleg Alexandrov (talk) 00:35, 20 October 2005 (UTC)
- Ah. In that case, I agree. That section could well do with a rewrite. -- Fropuff 00:52, 20 October 2005 (UTC)
- The old section seems confused. It claims that you can't reflect through a point; in fact, I reflect through points all the time in both math and physics, in different dimsensions, and I don't need a Euclidean structure to do it. Melchoir 20:53, 1 December 2005 (UTC)
