Anesthetics & Platonic Principles: Meditations on the Quantum Brain

Is consciousness like cruising in a canoe on a calm river that gently flows in one direction? Or is it more like a jet-ski ride where we leap over the water’s surface and then slap down again and again like a zig-zagging bull-frog?

Physicist Sir Roger Penrose thinks human consciousness works as discrete conscious moments, more like a jet-ski ride. We don’t recognize them as individual “moments” because consciousness feels continuous; it feels like a smooth ride.

In these discrete moments we interact with the quantum field. Imagine the quantum field as an ocean of waves where the tips of the waves represent physical reality and everything else potentiality. In this view, our perception of the material world is just the crest of a wave in the sea of possibility, and consciousness is an act of riding the waves.

According to research on the brain, we have 40 to 100 or more experiences of “cresting” each second. Or to put it another way, we have 40 to 100 experiences of conscious awareness each second.
Stewart Hameroff has studied consciousness from the perspective of an anesthesiologist. What is it that removes consciousness when you “go under” from anesthetic drugs? What is it that restores consciousness? What the heck is consciousness?

Trompe L’oeil, A Trick Of The Light: Interpretations of Quantum Mechanics

The quantum world is weird and illusive. Is it a trick of the light that scientists can’t determine if ours is a world of waves or particles?

When Ice melts in your hands and pools at your feet, do you question that it is water slipping, dripping through your fingers? Are you even surprised by its metamorphosis?

Just as water can be observed in more than one state, matter, in general, can apparently change states. The double-slit experiment shows that small matter is a wave until the wave becomes a particle; the wave changes to a particle, apparently, through participation with an observer.

Bruce Rosenblum and Fred Kuttner in their book, Quantum Enigma describe the puzzle this way:

“A small object is sent into a pair of well-separated boxes. Looking into the boxes, you always find the whole object in a single box, and the other box empty. According to quantum theory, however, before the object was observed, it was simultaneously in both boxes, not wholly in a single box. An interference experiment, which you could have chosen, would have established that. By your free choice, you could establish either of two contradictory prior realities.”

How can something be in two boxes at once? A wave can be in more than one place, but a particle is in one place only, right?

The is it a wave or is it a particle question still disturbs physicists in the 21st century, almost a century after the discovery of quantum mechanics. The main problem remains: does the wave collapse to a particle due to observation? What counts as an observer? Does the wave collapse at all? Could something else explain the quandary posed by the double-slit experiment?
