First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.
Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.
Thermo-Demonics
A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.
Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.
Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Essay Abstract
Category theory is a type of mathematics that challenges us to rethink fundamental ideas about numbers, as experimental outcomes. Essential to quantum field theory, its role in gravity remains elusive. Such nonsense is introduced under the assumptions that (i) unification is a valid goal for physics and (ii) relativistic causality holds for local observables. Is fermionic spin analogous to Boolean truth? If so, we should remember that whatever is divided is also non separable, and this ultimate reality cares nought for all our vanity.

Dear Marni Dee,
what you explain is for me a surprising and refreshing upgrade of the Standard model of QM. You return to the fact, that we can give every ponderable object a flag and recognise it when required. This gives us hope that one day we can begin to understand QM.
Help us to end the frustration Longo described : "We understand QM when we have understood that there is nothing to understand".

It's a pleasure to read an essay from you. Charge quantization indeed forces one into the countable. This allows lattices to play a more central role, and by doing quantum mechanics in this integral form, many (once murky) mathematical relationships become manifest.
Your linear topos thesis foreshadowed much of the motivic amplitude results one sees today. In such amplitudes particles are assigned to projective space points, which are idempotent morphisms in a magma-like structure.
Suppose we scatter n-(indistinguishable bosonic) particles and study the MHV amplitude in CP^3. Geometrically, the n-particles localize on a single copy of the projective space, on a curve of some given degree and genus. Any given individual particle is equivalent to another particle through an isometry that maps an idempotent to another idempotent. This is a higher level morphism, mapping idempotents to each other.
Going higher, one can map projective lines, or degree one genus zero curves to each other via collineations. It takes two idempotents to define a line, hence such morphisms map pairs of idempotents. By induction, in complex projective n-space, one can envision ever higher levels of k-idempotent maps, which map hyperplanes to each other. This is where the Grassmannian structure becomes obvious, and combinatorial structures like the amplituhedron organize the hyperplane configurations quite effectively.

Dear Marni Dee Sheppeard,
Since MacLane and Birkhoff I have avoided the square logic map diagrams, but I nevertheless managed to find quite interesting remarks in your essay.
Your abstract states "all we can really do is count." I begin my essay (and other essays) based on counting as the prototypical logic machine, constructed from NOTs and AND 'gates' which are ubiquitous in physical reality and manifest at all levels, RNA/DNA/proteins to telomeres, to insects, crows, neurons, silicon, etc. It is also the case that the key quantum field theory operator is the Number operator, or counter. So, with Kronecker, counting seems to be the sufficient basis for "all the rest" of math.
You note of the Standard Model, which is poorly understood, that enormous effort went into maintaining locality, while quantum physics would abandon it. My essay offers a novel analysis of this problem, which a recent comment on my thread describes as having a "self-concealing nature", thus making it extremely hard for physicists to see the error in logic. It is not a mathematical error, but a mapping error.
I do not believe classical physics requires distinguishability of particles as you seem to suggest, although, as you further suggest "for truly non-separable concept of existence, we must reinterpret the continuum of C."
I'm sure I've missed some of the more subtle issues of your essay, but I hope you will read my essay and try to understand the subtlety within it.
Best regards,
Edwin Eugene Klingman

Thanks for sharing this Marni,
As usual, you bring a perspective it's hard to find anywhere else.
