title: WPA block face card for household census (block 1503) in Los Angeles

description: The Works Progress Administration Los Angeles Household Census Cards collection dates from 1939. The physical cards which number nearly half a million items are owned by the USC Libraries. More than a quarter of the collection has been digitized.The household survey cards (or "dwelling schedules"), one for each street address in greater Los Angeles, document a wide variety of information ranging from the type of dwelling, the value of the property, the monthly rent or mortgage, to whether or not there were flush toilets. While these cards form the bulk of the collection, other digitized documents include "block face cards" and "block lists" -- documenting the census process.

title: The Torus Resolution of the Lorentzian Signature Problem in Spectral Geometry

description: We present a complete resolution of the long-standing problem of transitioning from Euclidean to Lorentzian signature in noncommutative spectral geometry. Thekey insight is that the torus T 2, which naturally emerges from fermionic zero modes in the axial vortex background, provides a canonical bridge between signatures.By considering a one-parameter family of tori with metric ds2 = R2 τdτ2 + R2 zdz2 and modular parameter τ = iRτ/Rz, we show that analytic continuation τ → it (t ∈ R+) transforms the Euclidean torus into a Lorentzian one while preserving theunderlying topological structure.The noncommutativity parameter θ plays a crucial role: it guarantees absolute convergence of all spectral sums throughout the continuation via the positivedefinite term θ2 4 (m2 R2 τ + n2 R2 z)2 in the eigenvalue spectrum. This allows us to define theLorentzian spectral action

SL(t) = TrT 2 t [χ(−D2 t /Λ2 cut)]

as the analytic continuation of the Euclidean action

SE(τ) = TrT 2 τ [χ(D2 τ/Λ2 cut)].

Causality emerges naturally from the spectral condition |m|/Rt < |n|/Rz, which in the decompactification limit Rz → ∞ becomes the standard light-cone condition.Microcausality follows from the spectral decomposition of the Dirac operator. The construction seamlessly integrates with the Berezin operator formalism, allowing analytic continuation of all physical observables.This resolution completes the rigorous foundation of quantum gravity as spectral geometry, solving the last fundamental problem in the program. All remainingchallenges are technical rather than conceptual, paving the way for detailed phenomenological predictions.
