### Which interpretation of quantum mechanics ?

I have spent one week in arguing with a specialist last time I've asked about that !For me the transition between the quantum world to the classical one is due to decoherence (interferences of your wavepacket with the surrounded wavepackets of the universe and the classical limit emerges from this chaotic noise). For the measure interpretation, that's another problem which is linked. Taking the measure of a quantum system is just coupling this system with the wavepackets of your measurement device and then it's similar to a projection on the eigenstates due to the fact that your measurement system is far much more bigger than your quantum system.That's my view but it's still a VERY HOT topic

Maybe we should build a little foundation here, so people who are new to QM can enjoy thinking about it.I will summarize some of the main ideas after I have emerged from the "she is eating Blueberry pancakes with maple syrup" quantum state.

Step over the gap, not into it. Watch the space between platform and train.

Yes, maybe non-formerly-physicist (and also some of them ) could have a look at this.

Transactional interpretationThe transactional interpretation of quantum mechanics (TIQM) by John G. Cramer is an interpretation of quantum mechanics inspired by the Wheeler?Feynman absorber theory.[15] It describes quantum interactions in terms of a standing wave formed by retarded (forward-in-time) and advanced (backward-in-time) waves.i vote for this one, LOL

Anything but the many-worlds interpretation.

But I see no reason that either the microscopic or the megascopic world should have intuitive interpretations. No doubt all these different scales interconnect in some mesh of aggregating and accumulating effects (assuming one believes that the behaviour of small particles drives the behaviour larger entities and that long time scales are composed of successive small time scales). But those interconnecting rules may include emergent effects or cardinalities that exceed the capacities of human intelligence.

So maybe look hard at Copenhagen. **PS: I have started a new thread: QM for the Subatomically Challenged (not to say "Dummies").
