Although I agree with much of what the RTSP page contains, I'm worried about some of the terminology, specifically the absence of any discussion of RTSP methods. For example, I'd be happier if we referred to the PLAY method and the PAUSE method instead of the PLAY and PAUSE requests.

Alternatively, could we at least mention that methods are the actions that the client requests the server to perform on an object ("The method indicates what is to be performed on the resource identified by the Request-URI")? That might also entail a brief description of the client-server model whereby client messages are requests and server messages are responses. In that context, the PLAY request would be understood to refer to a message, sent from the client to the server, with a PLAY method. Similarly, a PAUSE request is a client-to-server message whose method is PLAY. Further, a PLAY or PAUSE response would be understood as a response by the server to a PLAY or PAUSE request.

There is a possible complication that someone might want to investigate: The draft rfc2326bis lists a few requests that can be initiated by the server: "RTSP messages consist of requests from client to server or server to client and responses in the reverse direction." GET_PARAMETER, OPTIONS, PLAY_NOTIFY, REDIRECT, SET_PARAMETER, TEARDOWN -- messages with these methods can be sent in the S->C direction (from server to client). I think this means that in some circumstances a server can initiate request; I'm not used to that kind of behavior, but, hey, it's the IETF and anything goes. But right now I don't have the time and energy to pursue the matter. May others succeed where I fall flat.

But as I said, the page is probably alright as it stands as long as none of the IETF syntax gurus read it too closely.

Three pictures of quantum mechanics
There are three pictures of quantum mechanics: Schroedinger, Heisenberg, Dirac or Interaction. In chapter 1 of Introduction to Modern Quantum Optics the authors briefly describe the three pictures and indicate the criteria for choosing one picture over another. Those criteria are descriptive power and ease of computation. It might be a good idea for the section Mathematical_formulation_of_quantum_mechanics to have an introductory paragraph that does likewise. Telecomtom (talk) 00:19, 26 December 2011 (UTC)
