Sir Richard P feynman : I think that I can safely say that nobody understands quantum mechanics.
Yes. But what I have in picture I will give you.
Rule : Nothing exists unless until you measure it.
So whatever you observe are the observables. Once you observe it that means you are mesauring it. Like position, mommentum. In order ot measure you should operate observables operator on the Wave Function or what it represents the particle or the system. system can be anything from electron to atom to group of atoms to human anything. now if you want to find the position act the operator for the position on the wave function. Then it gives the position. oooo...wait wait... Im confusiing.
Let me put it in a humorous way.
Suppose a boy wanted to have a relation with a girl. so what are the possibilities. he will have realtion, no relation, or just he will meet her and never meet her again and so and so on....
So if I write the wavefunction of the guy with respect to the variable relationship with the girl.
WF = P1|long lasting realtion>+P2|few days realtion>........+Pn|he will never meet her>
|function> is nothing but a state. |Fn> form a complete orthonormal set. i.e There is no other possibilty.
Now the question is wats the propability of finding the guy with gal. Now operate it with relation operator or multiply it with ket (<> ) and
=0 for others.
so we get the required Pn value. Pn's are nothig but probabilities associated with each ket.
So now unless until we go and see /observe both we dont know wats the relation between them. Once we measure it All the values dimish and just we see the only relation...
Hope u "dint" understand. Yes you will not....Its nothig but Qunatum Mechanics. No body can understand....as Feynman says. Doubts are abosolutely welcome...to get urself more confused.[:P]
