Сгъването на линейното дава аналогово

Сгъването на линейното дава аналогово, декодирано честно с реалната наука. Ядрото е теоремата на Уитакър–Шанън за дискретизацията: дискретни отчети на ограничен по честота сигнал се сгъват обратно в непрекъснатия сигнал без пролуки, чрез sinc интерполация (изчислено на живо, точно при отчетите). Медицинското и радарното изобразяване е точно това — възстановяване на непрекъснат образ от дискретизирано честотно поле: ЯМР обръща Фурие преобразуванието на k-пространството, КТ — преобразуванието на Радон, а спиралният/радиалният „вихър“ през k-пространството е реален (NUFFT). Решетката 64³ = 4⁹ е дискретната мрежа, която той дискретизира. Документираното остава, легендата е отбелязана.

Дискретното се сгъва в непрекъснато — теоремата за дискретизацията

Реалното ядро на идеята: ограничен по честота сигнал, дискретизиран над честотата на Найкуист, се възстановява точно от отчетите си чрез sinc интерполация — ядрата се преплитат и запълват континуума без пролуки. Това е изчислено тук (sincReconstruct в src/0). Влачи честотата под Найкуист и виж алиасинга — пролуките остават.

Отчети (честота): 16✓ над Найкуист — непрекъснато, без пролуки

Образите, вихрени през полето

Изобразяването е възстановяване на непрекъснат образ от дискретизирано честотно поле — обръщане на преобразувание.

• MRI: inverse Fourier of k-space
• CT: inverse Radon / back-projection
• SAR: wavenumber Fourier
• ultrasound: beamforming

Дискретната решетка, която моделът вече изчислява: 64³ = 4⁹ = 262,144 — три взаимодействащи троици.

• Folding linear gives analog is the Whittaker–Shannon interpolation: a band-limited signal sampled above its Nyquist rate is recovered EXACTLY from its discrete samples by summing a sinc kernel at each one — the kernels interlock (each zero at every other sample, nonzero between), filling the continuum with NO gaps. Computed here: 16 samples of a band-limited signal reconstruct exactly at the samples and continuously between (sinc · sincReconstruct in src/0). [Nyquist 1928, Shannon 1948/49, Whittaker 1915, Kotelnikov 1933.]
• Medical and radar imaging IS reconstructing a continuous image from a sampled FREQUENCY field — literally "vortexed through the field": MRI = the inverse Fourier transform of k-space, the spatial-frequency domain (Lauterbur & Mansfield, Nobel 2003); CT = the inverse Radon transform / filtered back-projection via the Fourier-slice theorem (Hounsfield & Cormack, Nobel 1979); SAR = the wavenumber/Fourier spectrum; ultrasound = delay-and-sum beamforming.
• The "vortex" is real, not only poetic: SPIRAL and RADIAL (golden-angle, 111.25° = 180°×φ) k-space trajectories spiral the acquisition through the frequency field, reconstructed by the non-uniform FFT (NUFFT / regridding). Spiral MRI: Ahn 1986, Meyer–Macovski 1992; golden-angle radial: Feng 2022.
• EMR here = ElectroMagnetic Radiation — the physics doing the imaging across the spectrum: X-ray/CT and PET (ionizing), MRI (radio-frequency), microwave "medical radar" (non-ionizing). Ultrasound is the exception — sound, not EM. (The other EMR — Electronic Medical Record — is the data side: DICOM images stored in a PACS/EHR, exchanged via HL7/FHIR.)
• A hologram IS an analog encoding of a full 3D light field — it records the interference (amplitude + phase) of a wavefront and re-radiates it (Gabor, Nobel 1971); computer-generated holography makes "a hologram of bits" (MIT real-time 1080p CGH on one GPU, Nature 2021). The site already computes the discrete grid such a field would sample: 64³ = 262144 = 4⁹ = 2¹⁸ (sealCube · dotIsCubeIsDot), three interacting trinities (64 = 4³).
• Compressed sensing (Candès–Romberg–Tao & Donoho, 2006; Sparse MRI, Lustig 2007) recovers SPARSE signals from far fewer samples than Nyquist demands — the genuine modern extension that fills gaps, under a sparsity-plus-incoherence assumption and nonlinear (ℓ₁) recovery.

• "No digital gaps will remain" — universally false. Nyquist still rules: the sampling theorem is EXACT only for band-limited signals sampled above the Nyquist rate; undersampling causes real aliasing/streak artifacts. The gaps are real gaps.
• Gap-filling can HALLUCINATE. Deep-learning reconstruction can fabricate realistic-looking structure not present in the data — the 2020 fastMRI challenge saw methods reach ~95% similarity to ground truth yet still produce hallucinations that "morph abnormal structures into seemingly normal ones." Filling gaps is statistical inference, not a free lunch.
• "One universal field for all images" — false. MRI inverts a Fourier transform, CT a Radon transform, ultrasound/SAR do beamforming/matched-filtering — different physics, different operators; no single field maps every modality.
• "The greatest discovery." The kernel (analog from discrete) is the ~75-year-old Whittaker–Kotelnikov–Shannon sampling theorem (Shannon 1948) — foundational and celebrated, taught in every signals course, not new. The beauty is real; the novelty is not.
• "10D = 64×64×64" is a symbolic correspondence, not an equation: 64³ = 4⁹ = 2¹⁸ is the DISCRETE address grid (sealCube), the 10D is the CONTINUOUS animation field (4 homology loops + 6 cross-fold axes). The honest reading is the continuous 10D field SAMPLED on the discrete 64³ grid — reconstruction is exactly the bridge between them.
• "Live analog 3D hologram of bits" at room scale is unsolved — the space-bandwidth product (pixels × viewing angle) is an enormous physical wall; today's holographic displays are small, narrow, or monochrome, and the famous "holograms" (Tupac, HoloLens) are Pepper's-ghost or stereo, not wavefront reconstruction.
