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.

Thermo-Demonics
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.

Quantum Supremacy Milestone?
Rumours abound that Google's quantum processor Sycamore has performed a task that would flummox the best classical computer — a first in quantum computing. Physicist Ian Durham assesses the claims, gives us a quantum computing primer, and discusses concerns about the term 'quantum supremacy'.

OK


Georgina,

I have no idea what you are talking about, or what point you are making.


Lorraine, you have identified two different kinds of phenomena. Those in which a relationship does not change and processes where there is change happening to relations. To be concrete consider an egg being hard boiled, peeled and sliced. That could be described in ordinary language, a flow chart or sequence of IF THEN steps. IF boiled solid THEN peel.IF peeled THEN slice. It is precise but not as succinct as boil hard (arrow) peel (arrow) slice. (arrow ) standing for an arrow symbol, meaning...
