I don't know if this counts as Objectivis music, but I used Rand's interview to create a piece. I made a music video for it and uploaded it to YouTube - your'e welcome to listen, view and rate!

I have encountered the following dillema: Suppose there's a man called A, and A owns an object called X. There is also a man called B. A decides to give X to B, and B accepts it. Now, if property exists in reality, then since this transfer invloved only mental processes, that is, only a change of perception, then either reality is dependent of perception which is a contradiction, or property is merely and idea, and not something that exists in reality. How can this conflict be resolved? Also , please forgive my poor English. English is not my native language.

I am now studying the Aharonov - Bohm effect, and I am very puzzled about it. Does this effect suggest non locality of the magnetic field? If not, does it suggest that vector potential is a physical entity? If it does, then how do I reconcile gauge invariance with the identity axiom?
