"They are the one represented" is a yet another assertion. I would be more inclined to listen, if you'd show how a group of pebbles can conduct a measurement.

If I killed all animals capable of counting, "abstract immaterial numbers" would become exactly that: immaterial. > Pebbles can't count themselves, obviously.

The universe does what it does, it certainly doesn't solve equations. People solve equations, when approximating what universe does. As such, QM is a fair approximation; it has no further reality beyond that. H\psi=E\psi in absence of context is just as meaningless as 2+2=4. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net
