If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.
Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Can Choices Curve Spacetime?
Two teams are developing ways to detect quantum-gravitational effects in the lab.
The Quantum Engine That Simultaneously Heats and Cools
Tiny device could help boost quantum electronics.
The Quantum Refrigerator
A tiny cooling device could help rewrite the thermodynamic rule book for quantum machines.
Time to Think
Philosopher Jenann Ismael invokes the thermodynamic arrow of time to explain how human intelligence emerged through culture.
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.

Quantum Limits of Knowledge 2021
Tuesday 30th March, 2021
Users of a physical theory are themselves part of the physical world. This obvious fact leads to a requirement on any physical theory that is supposed to be universally valid: The theory must be able to correctly describe the users of the theory. Quantum theory (assuming it is universally valid) thus imposes limits on our knowledge in two different ways. Firstly, when we use quantum theory to describe an experiment, we obtain constraints from the familiar Heisenberg uncertainty relation. Secondly, when we take into account that the process of using quantum theory is itself a quantum mechanical process, we encounter 16 other, less familiar, limits. In my talk I will try to shed some light on this second aspect, which is much less well known than the first.
