Part 1: Sir Roger Penrose & Stuart Hameroff: What is Consciousness? (#247)

A conversation with Nobel Prize Winner and renowned mathematical
physicist Sir Roger Penrose and anesthesiologist Dr. Stuart
Hameroff about consciousness and quantum mechanics. 00:00 Intro
01:00 Happy Birthday to Sir Roger! 05:00 Updates to The Emperor's
New Mind 07:00 What about Schrödinger’s Cat? Part 2:
https://youtu.be/OoDi856wLPM Sir Roger Penrose and Dr. Stuart
Hameroff have tackled one of the most vexing problems in science --
how does consciousness work? Their theories of consciousness were
selected by the Templeton Foundation for study. We will discuss Is
the brain a sophisticated computer or an intuitive thinking device?
Following on from their conference in Tucson which pitted
Integrated Information Theory (IIT) against Orchestrated Objective
Reduction (Orch-OR), Sir Roger Penrose OM and Stuart Hameroff
discuss the current state of theories that might explain human
consciousness and objections to them from FQXI and others. Sir
Roger Penrose describe examples of ‘non-computability’ in human
consciousness, thoughts and actions such as the way we evaluate
particular chess positions which cast doubt on ‘Turing’ computation
as a complete explanation of brain function. As a source of
non-computability, Roger discuss his ‘objective reduction’ (‘OR’)
self-collapse of the quantum wavefunction which is a potential
resolution for the ‘measurement problem’ in quantum mechanics, and
a mechanism for non-computable physics. Dr. Stuart Hameroff reviews
neuronal and biophysical aspects of Orch OR, in which
‘orchestrated’ quantum vibrations occur among entangled brain
microtubules and evolve toward Orch OR threshold and consciousness.
The nature, feasibility, decoherence times and evidence for quantum
vibrations in microtubules, their role and correlation with
consciousness, effects upon them of anesthetic gases and
psychedelic drug molecules will be discussed, along with Orch OR
criticisms and predictions of microtubule quantum vibrations as
therapeutic targets for mental and cognitive disorders. Be my
