Every point is a circle
Draw a line through the centre of a circle. Each point on that line belongs to its own circle, concentric with the first. Walk outward and the curvature flattens toward a straight line — a graph. Walk inward and continuity dissolves into a logic graph before it reaches zero. Infinity is not at the end of the walk; it is the regime the walk enters.
The three regimes
Z · X · Y
Z — logarithmic
Sub-zero dimension. Infinitesimal structure, fractal detail, the pre-continuum logic graph. Zero, seen from here, looks like an infinity.
X — linear
Classical Euclidean geometry. Ordinary circles, ordinary angles, the calm middle where measurement behaves.
Y — exponential
Asymptotic flattening. Infinite radius, graph-like limit, angles that point at magnitudes rather than at particulars.
The crucial observation from infinitecircle.md: in linear-exponential dimensionality, a field can be laid out as a square in which horizontal, vertical and both diagonal neighbours all sit at distance one — or at the infinitesimal 1Z, or the infinite 1Y. Same angular density at every magnitude. This is precisely the property the octahedral quilt has, and it is why the ball can carry an infinite field on a finite skin.
The infinite circle — drag the magnitude
Exterior
The outside is the inside, folded
exterior.md asks what lies beyond the last circle. Laegna's answer is an inversion: the exterior is the interior read through r ↦ 1/r, glued along the unit membrane. Nothing is added; a direction is reversed. What was density becomes sparsity, what was containment becomes exposure, and the same geometry serves both.
On the ball this is literal. One side of the surface faces in, one faces out; the seam of the quilt is the fixed set. A statement made about the ball's interior has an exterior dual, obtained by reading the same quilt through the inversion. Laegna calls this the two-sidedness of any true thing — and Logecs later names those sides I and E.
Interior ↔ exterior, one membrane
Octave
Where infinity restarts
Projected infinity does not diverge; it saturates and wraps. As a quantity approaches the membrane, its exponent grows outward while its linear frequency collapses. Fully out-zoomed, the projection has swept a complete 360°, and the next octave begins at zero.
Collapse and restart
As x → 2 the exponent grows outward while the ball collapses inward: the outward growth eats its own linear frequency until, fully out-zoomed, the projection has swept a full 360° and a new infinity octave begins at 0.
Why this is not a trick
Renormalisation, logarithmic scales, floating-point exponents and musical octaves all already do this. Laegna's contribution is to make the wrap a geometric object rather than a change of units: the membrane is drawn, the octave index is a coordinate, and a value at the boundary of octave n is the same value at the origin of octave n+1 — not an analogy, an identity.
This is why the ball is the right carrier. A ball has a boundary that is finite in area and infinite in what it can address, once you allow refinement to continue in octaves.
SimulationMode
Infinities you can run
SimplyAboutInfinities/SimulationMode carries the numeric companion to this theory: tabulated behaviour of the regimes under sampling, so that a claim about Y-space can be checked against a finite run rather than argued. The pattern matters more than any single table — a Laegna claim about infinity is expected to come with a finite mode in which it can be simulated, exactly as the ball comes with a finite octave k at which it can be drawn.
