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.

All of the philosophers and physicists who have ever lived have been wrong about the real Universe because they failed to consider whether or not there could be only one verifiable universal physical condition. They compounded this lack of consideration by trying to incorporate complex, finite abstract mathematical systems into their thought processes in order to try to produce some sort of predictable reliability in the seeming chaotic diversity of reality.

Obviously, Nature must have...

Post-truth or post-sanity world?

Nature: "The Oxford Dictionaries named 'post-truth' as their 2016 Word of the Year. It must sound alien to scientists. Science's quest for knowledge about reality presupposes the importance of truth, both as an end in itself and as a means of resolving problems. How could truth become passé? [...] Post-truth refers to blatant lies being routine across society, and it means that politicians can lie without condemnation. This is different from the cliché...

Rather than showing retro-causality: the evidence suggests the electrons, or other particles, are something interacting with and altering their environment; making waves. Giving a cumulative manifestation resulting from the entirety of behaviour and its effect.

In the double slit experiment waves are spreading out from the vibration of the particle and apparatus. Upon reaching the double slits the wave disturbance of the medium will pass though leading to interference of the waves...
