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'.

Yes - of course! That is what the word "quantum" means! That is what I have been trying, without success, to get you to understand. Here is the original, experimental proof, from the 1920s

The observed result, (5), has nothing to do with what any humans are doing. The interaction between each individual atom (2) as it passes through the magnetic field (3) results in one of only two, distinct outcomes. Each individual atom is either deflected "up" or deflected "down". There is never any in...


Rob,

Re my words e.g.: “I believe that physicists can take accurate measurements”:

You can see that I am talking about human beings (physicists). But you are referring to the problem of sending accurate reliable coded messages in telecommunications and computing. Which has got nothing to do with physicists taking measurements because:

A thing being measured is not sending a coded message to the physicist, and the physicist is not sending a coded message to the thing...


Agreed. Binary digits don't support the underlying physics. The underlying physics is supported by unit quantities of action.
