Peter Woit, University of Columbia, ‘Towards a Grand Unified Theory of Mathematics and Physics’.

A paper which outlines some of the already established connections between number theory and physics, acknowledges that there are as yet no satisfactory explanations for these connections, and concludes it is an area which deserves much more attention.

maths is so useful for physics because it’s developed from the same fundamental principles which govern the physical universe

early humans didn’t invent systems of number, then discover they were useful for measuring and quantifying the physical world

early humans developed systems of number from observation of how the physical world is naturally organised: counting systems are based on measuring and comparing the physical properties of different groups of the same or equivalent physical objects

for *any* type of equivalent physical objects

the quantity we call 1
put with the quantity we call 2
creates the quantity we call 3

this is a physical absolute, according to the law of conservation of energy

numbers and numerical relationships are not merely abstract concepts, they are developed from the same fundamental principles as physical laws

The theory of everything set out on this site explains from first principles, precisely this.

the properties of the elementary particles in the Standard Model of particle physics may be inferred by studying the largest cosmic structures

Why Is Space 3-Dimensional?

“The Helmholtz free energy density (f) reaches its maximum value at a temperature T = 0.93, which occurs when space had n = 3 dimensions”

“We demonstrate a topological classification of vortices in three-dimensional time-reversal invariant topological superconductors based on superconducting Dirac semimetals with an s-wave superconducting order parameter by means of a pair of numbers (NΦ,N), accounting how many units NΦ of magnetic fluxes hc/4e and how many Nchiral Majorana modes the vortex carries. From these quantities, we introduce a topological invariant, which further classifies the properties of such vortices under linking processes. While such processes are known to be related to instanton processes in a field theoretic description, we demonstrate here that they are, in fact, also equivalent to the fractional Josephson effect on junctions based at the edges of quantum spin Hall systems. This allows one to consider microscopically the effects of interactions in the linking problem. We therefore demonstrate that associated to links between vortices, one has the exchange of quasiparticles, either Majorana zero modes, or e/2quasiparticles, which allows for a topological classification of vortices in these systems, seen to be Z8 classified. While NΦ and N are shown to be both even or odd in the weakly interacting limit, in the strongly interacting scenario one loosens this constraint. In this case, one may have further fractionalization possibilities for the vortices, whose excitations are described by SO(3)3-like conformal field theories with quasiparticle exchanges of more exotic types”.

“We consider time-dependent solutions of the Einstein-Maxwell equations using anti–de Sitter (AdS) boundary conditions, and provide the first counterexample to the weak cosmic censorship conjecture in four spacetime dimensions. Our counterexample is entirely formulated in the Poincaré patch of AdS. We claim that our results have important consequences for quantum gravity, most notably to the weak gravity conjecture”

“The neutrinoless double-beta (0νββ) decay is a unique process to identify the Majorana nature of massive neutrinos, and its rate depends on the size of the effective Majorana neutrino mass ⟨m⟩ee. We put forward a novel “coupling-rod” diagram to describe ⟨m⟩ee in the complex plane, by which the effects of the neutrino mass ordering and CP-violating phases on ⟨m⟩ee are intuitively understood. We show that this geometric language allows us to easily obtain the maximum and minimum of |⟨m⟩ee|. It remains usable even if there is a kind of new physics contributing to ⟨m⟩ee, and it can also be extended to describe the effective Majorana masses ⟨m⟩eμ, ⟨m⟩eτ, ⟨m⟩μμ, ⟨m⟩μτ and ⟨m⟩ττ which may appear in some other lepton-number-violating processes”.

Paul Benioff (2005), ‘Towards a Coherent Theory of Physics and Mathematics: The Theory–Experiment Connection’, Foundations of Physics, 35: 1825.


“The problem of how mathematics and physics are related at a foundational level is of interest. The approach taken here is to work towards a coherent theory of physics and mathematics together by examining the theory experiment connection. The role of an implied theory hierarchy and use of computers in comparing theory and experiment is described. The main idea of the paper is to tighten the theory experiment connection by bringing physical theories, as mathematical structures over C, the complex numbers, closer to what is actually done in experimental measurements and computations. The method replaces C by Cn which is the set of pairs, Rn,In, of n figure rational numbers in some basis. The properties of these numbers are based on those of numerical measurement outcomes for continuous variables. A model of space and time based on Rn is discussed. The model is scale invariant with regions of constant step size interrupted by exponential jumps. A method of taking the limit n→∞ to obtain locally flat continuum-based space and time is outlined. Also Rn based space is invariant under scale transformations. These correspond to expansion and contraction of space relative to a flat background. The location of the origin, which is a space and time singularity, does not change under these transformations. Some properties of quantum mechanics, based on Cn and on Rn space are briefly investigated”

The top replies to this question on Quora are classics of the genre – acknowledging how fundamental the relationship is between maths and physics, acknowledging that this relationship is still not fully understood or explained, but leaving it open – failing to interrogate the implications and significances.
