Hello, I'm studying decoherence at the moment, as a result I've also been looking a wavefunction collapse. I was wondering what the definition of a full measurement is and whether they occur outside of the lab? - I've been looking at 'measurement like' interactions, which cause decoherence, but not actual collapse. I suppose my question boils down to: what's the difference between a measurement and a measurement like interaction? ... at the moment it seems to me that simply consciousness is involved in one but not the other! Thanks alot!
