It got pretty heated when Teg questioned Hameroff back in the day. Teg was correct in an absolute sense that its far to warm inside the skull to.present a quantum computation. But a quantum computation as a result of a quantum field effect seems to be a different story. How a quant field relates to an actual quantum computer is apparently different. Yet biologists for thqt last decade, have increasingly observed quant processes occuring in, for example, plants. This is where teggers, was too pessimistic, since he was looking for cold superconductivity, as a necessity for quantum computation, but quantum fields are related, but, different then qc. A bigger question I have is can we compute using quant field effect, or, more weirldly, do quantum fields compute, naturally, automatically?

In fact, the hard asses may be correct, technically, in the sense that the brain is not a quant computer, but as Clark points out, quantum field effects are everywhere in nature, a piece of bird poop, the electrons flow, disgustingly. Specifically, Teg went after Penrose and Hameroff, particularly Hameroff, several years ago. I wonder now with his MUH book is out last Jan, if he had changed his mind? Anyway, the field effects are everywhere and yes, Virginia, they are quantum. <div class="aolmail_h5"> <div> <div style="color:black;font-family:arial,helvetica;font-size:10pt"> -----Original Message----- From: John Clark < <a target="_blank" href="mailto:[email protected]";></a><a href="mailto:[email protected]";>[email protected]</a>> To: everything-list < <a target="_blank" href="mailto:[email protected]";></a><a href="mailto:[email protected]";>[email protected]</a>> Sent: Sun, Aug 17, 2014 12:31 pm Subject: Re: Electron spin and consciousness <div dir="ltr"> On Fri, Aug 15, 2014 at 2:18 PM, meekerdb <span dir="ltr"><<a target="_blank" href="mailto:[email protected]";></a><a href="mailto:[email protected]";>[email protected]</a>></span> wrote: <div class="aolmail_gmail_extra"> <div class="aolmail_gmail_quote"> <blockquote class="aolmail_gmail_quote" style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid"> > Maybe there is a quantum aspect to consciousness. <a target="_blank" href="http://www.pnas.org/content/early/2014/08/06/1404387111.full.pdf+html";></a><a href="http://www.pnas.org/content/"; target="_blank">http://www.pnas.org/content/</a><u></u>early/2014/08/06/1404387111.<u></u>full.pdf+html <span><font color="#888888"> </font></span> </blockquote> <div> As near as science can tell there is a quantum aspect to EVERYTHING. The paper says "We conclude that there may be a connection between spin, electron currents in cells, and the functioning of the nervous system", well... it would be very surprising indeed if a fundamental property like the electron's spin, a property as important as its charge, was not involved in the operation of nerves. IF the hard drive on your computer is newer than about 2003 (and if it isn't it's time to get a new computer) then it too makes use of the electron's spin and could not hold nearly as much information as it does if it did not. I don't see how electron spin has more to do with consciousness than electron charge. And general anesthesia not only causes you to loose consciousness it also causes you to loose intelligence which is yet another reason I think the two are inextricably linked.
