The Quantum Agent
Investigating how the quantum measurement process might be related to the emergence of intelligence, agency and free will.

First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

If neurons sometimes send and receive electromagnetic signals an obvious possible antenna is the microtubule in the axon. Penrose theorized that microtubules can act like a specialized quantum computer -- perhaps to filter and process the information supplied by photons being absorbed by the microtubule.

Microtubules of different neurons might absorb different frequencies of EM radiation. By experimenting and theorizing about which frequencies of photons would be absorbed -- those...

Input to the visual system is electromagnetic radiation which causes electric signalling to be produced from photo-receptors. In some cases it causes quieting of a signal that is the default condition. In the brain nerve impulses are electric and there are also chemical neurotransmitters involved in impulse transmission between nerve cells. I don;t think electromagnetic "light" signals play a role in the brain except in stimulating the pituitary gland and by doing so helping in the setting of...

The most important part of physics might be totally undiscovered and not looked for in experiments. Despite all the technological progress science has brought, maximum life span has not increased -- some people made it over 100 years old, thousands of years ago.

If we could move minds to highly engineered artificial bodies we could all live a very long time and each year artificial bodies could get better and be designed for a wide variety of environments in the universe.
