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.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Measuring Free Will -- Ian Durham
To what degree are our choices really free, rather than determined? And how much control do we have over them? Quantum physicist Ian Durham presents a new mathematical model for free will. From the 6th FQXi Meeting, in Tuscany.

Lie groups, there are SU(N),SO(N),Sp(N), and the exceptional G_2, F_4, E_6, E_7, and E_8.

About Lie groups,it's Indeed a wonderful tool for the ranking and fractalisation. That said ,I have suggested to Klee Irwin to consider these finite serie of sphères with cold and heat instead of points and strings.The distribution between the zero absolute and the planck temperature due to codes Inside these finite series of this gravitational aether can give relevant resulsts it seems to me...

There might indeed be a way to measure free will just like there is a way to measure wavefunctions, but free will has to do with neural action potentials. People who measure neural action predict our choice before we are conscious of a choice. They then imply that we do not have conscious free will, but that assumes that our subconscious choices are somehow random or otherwise not causal.

That seems unlikely since our subconscious is very important for consciousness and for making... did propose that a z-function would be a measurable freedom of choice, but then you failed to say how to measure a z-function. You say it would be the shortest distance in some phase phase or another, but that simply does not help at all.

Please say exactly how to measure free will. All you supposed that there is a measure of free will, not how exactly free will would be measured. I like how you do not deny a way to measure free will, but please give us the way.
