Lockdown Lab Life
Grounded physicists are exploring the use of online and virtual-reality conferencing, and AI-controlled experiments, to maintain social distancing. Post-pandemic, these positive innovations could make science more accessible and environmentally-friendly.

Is Causality Fundamental?
Untangling how the human perception of cause-and-effect might arise from quantum physics, may help us understand the limits and the potential of AI.

Building Agency in the Biology Lab
Physicists are using optogenetics techniques to make a rudimentary agent, from cellular components, which can convert measurements into actions using light.

Think Quantum to Build Better AI
Investigating how quantum memory storage could aid machine learning and how quantum interactions with the environment may have played a role in evolution.

Outside the Box
A proposed quantum set-up that could predict your game-playing strategy resurrects Newcomb’s classic quiz show paradox.

Emergent Quantum Mechanics--Special Edition
Special edition of the podcast recorded at the Emergent Quantum Mechanics meeting in London. Zeeya and Brendan chat to Nicolas Gisin, who argues that real numbers are not really real--and why that means that even classical physics is indeterministic, and the future is open. By contrast, Emily Adlam makes the case for a deterministic 'Sudoku Universe.' We have tips for the new essay contest, asking "What is Fundamental?" FQXi and the Fetzer Franklin Fund launch a new large grant round, on Agency in the Physical World, as Anthony Aguirre and Jan Wallaczek explain. And fine-tuning quantum theory, with Matt Leifer.

Edward Witten, in an interview with WIRED ___ ____ said "It from qubit" in natural language.

But a computer scientist would know that a software engineer versed in "formal specification languages"-- which are abstract programming tools used to specify what the real time programmers in assembly language should write-- might want to translate such a statement in natural language into an equation in a formal...

The real visible universe might only be more than a set of numbers - or we could also call it a simulation. The whole universe might not be "real" in general - but it is 100% real for us. Just like a computer program cannot escape its own reality in which it "lives" - the memory of a computer. Boundaries are yet to meet as we get to further technological advancements, so I hope we will soon come at least "closer" to the truth.


Joe, The sensory products I am referring to are related to sight. Those formed by the visual sensory system and brain of a sighted organism. Or the hardware of a device that produces an output from processing em radiation, 'vision-like'. That should have been clear as I have talked about the necessity for the material structures and em input for the process of vision to occur. It seems to me that the term visual sensory product may be more acceptable to scientists than 'Image reality'. Joe, you...
