Here's one of the last thoughts which arised in my mind. I have discovered there is some mathematical logic in the relationship between a man and a woman. :surprised And I have experimented this fact the last days. Let's call [tex]\Delta F[/tex] as the uncertainty about the friendship between a man and a woman. Also, let me call [tex]\Delta S[/tex] as the probablity of sucess when trying to pick up seriously with her and have a serious romance. Then, this two variables are relationed as something similar to Heisenberg Principle: [tex]\Delta F\cdot \Delta S > C[/tex] where [tex] C[/tex] is some finite constant. Proof: when you have a great friendship with a woman, you know, you have little secrets with her and viceversa, she laughs a lot with you and you laugh a lot with her, then the uncertainty about your friendship is 0: [tex]\Delta F=0[/tex] and so [tex]\Delta S=\infty[/tex], therefore you have no idea if it would be a great idea to flirt with her with the hopeness of sucess. On the other hand, when you know little about a woman [tex]\Delta F=0[/tex], all of us are sure we are not going to have sucess with her [tex]\Delta S=\infty[/tex], but also it could happen I try to join her and in few minutes I get sucess. Interesting, isn't it?.
