Hi creeky belly,

Thank you for your reasoned responses.

Buckminster fullerines don't behave like normal soccer balls because their quantum wavelength is proportional to their size (deBroglie's equation). That's essentially the best way for determining whether something will exhibit quantum effects. In addition, nuclear spin quantum computers have made use of a rather large molecule (like the one that figured out that 15 factors into 3 and 5), however, there's big difference between 1 molecule of a substance and 1 mol.

um....

E = h/t came directly from deBroglie's work.

"The de Broglie relations show that the wavelength is inversely proportional to the momentum of a particle and that the frequency is directly proportional to the particle's kinetic energy." link

Momentum and kinetic energy are proportional to mass, not size.

deBroglie's equations are...
p = hk
E = hw

When you substitute 1/t for w, you get the form Penrose uses.

I'm not here to debate with you the primary tenets of quantum mechanics;

My point is there is no such thing as a minor inconsistency in logic.  You would not be the first one to attempt to hand-wave away the inconvenient existence of "quantum weirdness".  For seventy years people have been waiting for the logical explanation to present itself.  Penrose quit waiting.  He accepted it as reality and built a consistent model to explain it all.  The final piece was consciousness.

Are you familiar with the story behind Penrose Tilings?

It started out as a mathematical curiosity.  At one time it was assumed that any effort to tile a surface (e.g. a floor) with a limited number of shapes would result in a repeating pattern.  This is known as periodic tiling.  However, attempts to prove that mathematically failed.  One day, someone proved that aperiodic tiling was, in fact, possible.  The race was on to find examples.  The first example had 20426 tile shapes.  To make a long story short, Penrose found a solution that used only TWO tile shapes (he did it in his spare time as “a hobby”).

This still might be considered just an interesting mathematical curiosity except for two things.  Ten years later, an “impossible” crystal formation was discovered.  You see it was thought that all crystals had to be made up of repeating structures (periodic).  An aperiodic crystal formation was discovered, it matched Penrose Tilings.

The second interesting aspect is that Penrose claims his solution couldn’t have been found algorithmically, i.e. Turing Machine couldn’t be programmed to find the answer not matter how powerful it was.

What I called "absurd" was ignoring the effects of the EM potentials and interactions, when they are much more dominant than gravity. You can't just handwave it away and say it will be fine, especially when the quantum computer is immersed in a electric dipole fluid along with one of the strongest ferromagnetic substances. That's absurd. All of this makes it less feasible that our brain can properly transport quantum information.


Penrose admits that he might be wrong on the details of how.  He isn't a biologist.  But it is obvious Penrose is firmly convinced he is right about the quantum physics.  The implications make others uncomfortable, but a lack of comfort doesn't hold a candle to experiment after experiment showing interconnected quantum effects are a reality.

Dr. Hameroff is convinced Penrose is right based on his experience in suppressing consciousness (anesthesia).
