About This Event

An exploration of the fundamental physics of consciousness and theories of conscious experience.

Consciousness is, without doubt, the most mysterious phenomenon in the universe and the most important to understand. Theoretical physics, frontier biology, and ancient spiritual philosophers across thousands of years have struggled with the nature of mind and its interactions with reality.

​Come and join us for presentations from leaders in the field to understand the science of philosophy of the rich world within.

​Speakers:

​James Tagg CEO and founder of Valis will describe efforts to build a large bio-computer called The Large Brain Model that may shed light on the question of quantum computation in the brain.

Stuart Hameroff anesthesiologist and professor at the University of Arizona and one of the originators of the Penrose-Hameroff theory of Orchestrated Objective Reduction. Stuart is also the main organizer of the Towards a Science of Consciousness conference.

Rajnish Khanna, M.Sc. Ph.D., is a Senior Investigator, Biosphere Science and Engineering at Carnegie Science, Stanford. Rajnish is the founder and Chief Executive Officer of i-Cultiver, Inc. Rajnish applies photobiology to explore the science of consciousness. He has developed a unique and testable “Theory of Spatial Relativity” relating to the origins of consciousness, which aligns modern science with ancient concepts. Rajnish is the host of TerreScience podcast. For a full bio, visit www.rajnishkhanna.com.

Speakers

James Tagg

James Tagg

Founder & President, The Penrose Institute

presenter

James Tagg is a serial entrepreneur and award-winning author. He was one of the original inventors of the touchscreen, founded Truphone (the world's first global mobile operator), made the first mobile phone call over the Internet, and developed the eSIM. He holds over 200 patents. James studied Physics and Computer Science at Manchester University, Design at Lancaster University, and Engineering at Cambridge. He co-founded the Penrose Institute with Roger Penrose. His venture Valis Corporation is developing a quantum biocomputer connecting 1,024 brain organoids (~500 million neurons). Author of "Are the Androids Dreaming Yet?"

Stuart Hameroff

Stuart Hameroff

Professor Emeritus of Anesthesiology & Psychology, University of Arizona

Stuart Hameroff is an American anesthesiologist and professor at the University of Arizona known for his studies of consciousness. He co-developed the Orchestrated Objective Reduction (Orch-OR) theory with Nobel laureate Roger Penrose, proposing that consciousness originates from quantum states in neural microtubules. He is the Director of the Center for Consciousness Studies and lead organizer of the Science of Consciousness conference. His work spans molecular biology, neuroscience, pharmacology, philosophy, quantum information theory, and quantum gravity.
