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.

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.

Physicists are using optogenetics techniques to make a rudimentary agent, from cellular components, which can convert measurements into actions using light.

Investigating how quantum memory storage could aid machine learning and how quantum interactions with the environment may have played a role in evolution.

I never understood Bohmian pilot waves associated with a particle. What makes the wave? Consider the simple case of the double slit experiment. If it was a bow-shock wave emitted from the particle, more of that wave would go through the same slit the particle would go through, and the interference pattern that would add up from that model would not match experiment. It is clear to me physicists are just 'hung up' on particles. What goes across space must be a wave. Then what makes the...

from the article,

"instead particles really are particles that occupy a definite position in space, regardless of whether or not they have been observed. On the subatomic scale, however, their motions are guided by a pilot wave, which isn’t a physical wave but rather a wave through a high- dimensional mathematical space."

Why not a physical wave? Why must it be a "wave through high-dimensional mathematical space?Is it because the aether has such a bad reputation?

In Einstein's words, 'elements of reality' are 'free creations of the mind'. On the other hand, Einstein believed into a deeper-lying theoretical framework when he spoke of objective reality. Accordingly, we may expect paradoxes due to incompatibilities between different points of view.

There are several cases where a mathematical model is correct and complete but not appropriate to its application.

Let me start with the joke of more people leaving a room and than it contains....
