- Yes, Mike you are quite correct. In fact, someone from Livermore O Group
- showed that the arrow of time can be derived from the influence functional.
- When the name pops up in my memory I'll post it. He used to drive me
- around in a Cobra in La Jolla in the 60's.

-
- Maybe so, but I am not convinced yet. I saw a new book by Haag on local
- dynamics in QM field theory - it looks good and I may shell out the $60 to
- relearn QM. But Josephson sort of waffles on communication (i.e. local
- decoding) for his idea. He certainly thinks that nonlocal coordination
- which is confirmed by Aspect mod detector loophole is important for life.
- So do I.. However, my point is that if precognition and remote viewing are
- real then nonlocal coordination without local decoding is not enough.
- Josephson does say in Foundations of Physics that living systems can
- communicate in my sense as well - but this is not within standard QM he
- would agree - it's something new. Evewn Eberhard is prepared to accept FTL
- communication, but beyond QM. Eberhard told me that directly. Have you read
- Steve Weinberg's new nonlinear extension of standard QM? What do you think?
- I'm told Weinberg's model does permit FTL local decoding.

-
- Not fair, as I explained earlier. I always accepted local dynamics in the
- jA coupling. It's all in the objective entangled wavefunction which I view
- as a premetrical hyperspace bridge if you like. No you don't like.

- Yes, of course.

-
- Yes, I read that long ago. I thought you meant some second paper, something
- new. I will re-read it though and comment.
