Relativity: The Special and the General Theory
Still the clearest statement of why simultaneity is a choice of chart. Read chapters 8–12 with the rapidity picture in mind and the Laegna reading writes itself.
Everything here is built on standard physics, read differently. This page tells you what to read first — and then tells you honestly how much is still unfinished, and how ordinary the unfinished work actually is.
There is a story people tell about science: that progress comes from rare geniuses having rare insights. It is mostly false, and it keeps capable people away. Most progress is careful work — combining, verifying, standardising, calculating, writing things down properly so the next person does not have to start over.
Laegna Physics is early. Its first-order combinatorics are not finished. There are no complete, proofread, formatted, verified papers covering even the primitive cases. That is not an embarrassment to hide — it is the actual opportunity. Compare it to the early days of software bug-hunting: the people who found the important bugs were not the most brilliant programmers alive. They were people who cared enough to study a thousand known bugs first, and then looked where nobody had looked yet. Or compare it to a map with white territory on it. You do not need to be the greatest explorer. You need to be someone who went.
The tasks below are real, they are mostly not conceptually hard, and several of them are worth a practical scientific credential to whoever completes them properly. Some are many hours of combining and checking. Some are an afternoon of careful arithmetic. All of them advance the same frontier that top-level science advances, because the frontier here is simply unvisited, not guarded.
Contributions should arrive as pull requests or issues against the LaegnaPhysics repository, with claims separated into: (a) restatements of standard results, (b) derivations within the Laegna chart, (c) conjectures. Category (c) is welcome and must be labelled. Negative results are publishable here; a demonstration that a proposed reprojection fails is worth as much as one that succeeds, and considerably more than silence.
You do not need all of this before you start. Two or three of the first entries are enough to follow every argument on this site and to spot it when one of them is wrong.

Builds special relativity from the invariant interval rather than from postulates about light. This is the closest existing textbook to the Laegna approach.
The source for Kruskal–Szekeres coordinates and Penrose diagrams — the conformal compactification that Laegna generalises. Chapter 31 is the direct precursor.
Amplitudes before probabilities, exactly the ordering Laegna insists on. The two-slit chapter is the canonical sub-threshold argument.
The technical account of how the record becomes classical while the field does not change. This is the threshold θ, derived properly.
Winding numbers, Berry phase, Chern classes — the invariants that survive compression. The mathematical backbone of the quantum-to-topology claim.
Entropy as inference rather than substance. Jaynes' 1957 papers are the shortest route to why kelvin reprojects to a basin width.
Causal structure, conformal infinity, singularity theorems. Where 'the pole is a place' gets its rigorous treatment.
Scale as a physical coordinate, stated first and best. Laegna's scale axis is Wilson's flow with the poles made explicit.
Not physics, but the best available preparation for paradox-aware self-referential number realms — the part of Laegna that goes past the poles.
Two standard diagrams, redrawn live. The Penrose-style compactification below is taught in every general relativity course, and it is already the compression map — it simply stops at spacetime instead of continuing into scale. The lightcone in rapidity coordinates is standard particle-physics practice, chosen because rapidity differences are boost-invariant. In both cases the working physicist made the Laegna move for practical reasons and did not name it.
Further already-visible instances worth cataloguing: Poincaré disc models of hyperbolic geometry; the Riemann sphere's point at infinity; Bode plots as octave coordinates; the Bloch sphere as an angular reading of a two-state amplitude; the logarithmic axis of essentially every experimental plot in high-energy physics. Each is an independent rediscovery of the same convenience. The Laegna claim is that the convenience is structural.
There is a habit in physics so ordinary that nobody calls it philosophy: when a quantity cannot be known, stop claiming it exists, and describe instead what stays reliable. Maxwell did not follow a single molecule. He doubted every trajectory at once, and what remained — the speed distribution — turned out to be predictive to several digits.
The simulation below shows both halves of the move. On the left, individual molecules: unrepeatable, untrackable, and physically useless one at a time. On the right, the same population as a measure — Maxwell–Boltzmann — which is stable, smooth, and holds even as you change the temperature. The dashed barrier marks a speed no single molecule is guaranteed to reach; yet the fraction that does is a fact you can compute and rely on. That tail is the statistical tunnel: escape velocity in a gas, evaporation, thermionic emission, the reaction rate of Arrhenius — and, one octave down, the quantum tunnelling of light through a barrier it classically cannot pass.
The Laegna reading is the same operation stated once, generally. Below the observation threshold there are magnitudes without events, and the only honest coordinate there is a measure. Above it there are dated facts. Doubting is the projection between the two layers — it does not destroy information, it removes the coordinates that carried none. Applied outside physics, this is what the Laegna study center calls physical philosophy: take a domain where the facts are unknown, keep only the forms that survive doubt, and see what still predicts.
Classical anchors for the same move, worth studying side by side: Maxwell (1860) on the distribution of velocities; Boltzmann's H-theorem; Gibbs on ensembles rather than trajectories; Jaynes on entropy as inference; the Wentzel–Kramers–Brillouin barrier integral for the quantum tail; and frustrated total internal reflection, where a statistical tunnel for light is directly measurable on a bench. Each replaces an untrackable fact with a trackable measure, which is precisely the Laegna threshold projection written in the vocabulary of its own century.
Laegna is larger than its physics. The same framework runs through mathematics, symbolic and archetypal work, and the long-term wide-scope reading called SpiReason. These are the roots from which the apps, galleries, papers and repositories branch.
Most of what is missing here is not genius work. It is careful work: tabulating, checking closure, re-deriving a known result in a new chart to see whether it still comes out. Plenty of it fits in an afternoon, and every finished piece makes the next one cheaper for whoever comes after.
Pick one. Each item below is stated so you can tell when you are done — that is the whole trick to unfinished science being approachable. If it comes out wrong, that is also a result, and a more valuable one than a confirmation. Write it up plainly, put it in a repository, and the map has one more marked square on it.
Reporting standard, so results compose: state the chart you worked in, the constraint set you assumed, and the check that would have falsified you. A negative result with those three lines is publishable inside this project. The arithmetic these tasks lean on is set out on the octaves page; classical grounding is in the sections above.
