In the Casimir effect, the force depends only on an energy difference. Zee's book has a simple explanation (naive derivation assumes perfect infinite conductors) and Jaffe has all the details. But for the cosmological constant, there be dragons!

Noise equals control
Stochastic systems have a control-theoretic interpretation in which noise plays the role of control. In the weak-noise limit, relevant at low temperatures or in large populations, this leads to a prec...

The Autotrophic Core: An Ancient Network of 404 Reactions Converts H2, CO2, and NH3 into Amino Acids, Bases, and Cofactors - PubMed
The metabolism of cells contains evidence reflecting the process by which they arose. Here, we have identified the ancient core of autotrophic metabolism encompassing 404 reactions that comprise the r...

I will be around at StatPhys and Molveno if you want to chat!

In the talk I explain it all in simple language, and reinterpret stochastic resonance & Brownian ratchets with the noise-control mapping.

It also solves a conceptual problem in the field theory of stochastic systems, which is the physical interpretation of the `momentum' field that is introduced as a Lagrange multiplier, or via other abstract methods. The field is a control strategy. Agency is part of Nature

This solves the conceptual `agency-body' problem of dualism, i.e. reconciling a mechanistic description of biology with an agential one

@philipcball.bsky.social potentially of interest! This result is very aligned with your perspective, I believe
