Subject: about cryonics and quantum mechanics

Hi again!

I note the discussion by John Clark in 14219 about quantum mechanics.

For what it may be worth, no neuroscientist believes that quantum mechanics
tells us anything at all about how our brain works. A few physicists have 
made such a claim, but familiarity with what we ALREADY NOW know about
how brains work will make such claims look implausible.

Yes, we don't understand the universe or any part of it. Even so, that
neuroscientists have this opinion should at least give us pause.

Could quantum mechanics someday bear on brains because we make ourselves
new brains which use it? Perhaps. But even if we do so, we'll need to
understand OUR brains much better than now. Is quantum mechanics an
interesting subject? Certainly, especially now that several physicists
and engineers are thinking about how we can use it. But it still doesn't
tell us anything about how our brains work.

			Best wishes and long long life for all,

				Thomas Donaldson
