The Quantum Theory and Reality (1979) [pdf]
Ok, I&#x27;m going to hijack this thread to get an answer to something I&#x27;ve always struggled with: how does &#x27;observation&#x27; cause the wave function to collapse.<p>It won&#x27;t happen in a closed box, but what about an open box in a closed room?  What about a closed box with a live video camera?  What about a live video camera whose display no one is watching?<p>I&#x27;m sure this is a basic question but for the life of me, I&#x27;ve never really understood it.  Thanks.
