δ = 4.669201609… — measured universal constant of period-doubling. Logistic onset near r ≈ 3.56995. A number, not a mantra.

sp² C–C ≈ 1.42 Å. Dirac fermions with Fermi velocity on the order of 10⁶ m/s. Solid condensed-matter fact.

LaFeAsO family; reported Tc up to ~55 K. s± pairing is a research model, not a household device.

Archean Δ³³S mass-independent fractionation (order of 12‰ in classic SO₂ photolysis papers). Earth's early-atmosphere letter, not a spell.

F electronegativity 3.98 (Pauling). Fr ionization energy is low (~380 kJ/mol). A textbook contrast of extremes — not a lattice to cook.

Shor, Grover, VQE exist as published algorithms. This library does not implement cryptanalysis.

Predicted region near Z ≈ 114–126, N ≈ 184. Research geography. Ubh-310 remains a sketch, not a recipe.

Public stellar target. Nickel and other metal lines are measured in Å/nm. Auroral [O I] 557.7 nm is a known airglow line. Spectroscopy, not a signal to a person.

Named for its seahorse shape (Greek hippos + kampos). Memory consolidation and place cells are textbook neuroscience. No family-tone overlay.

Binuclear manganese hydrolase (trimer in many eukaryotes). Heme formula C₃₄H₃₂FeN₄O₄ is standard. Personal farm-saga mentions stay Layer C and are not protocols.

I = I_c sin φ. Voice is not a superconductor.

t½ ≈ 1.4 × 10¹⁰ y. Long-lived and radioactive — not a stable isotope. ‘Stability’ here is relative timescale or metaphor.

He-4 nucleus: two protons, two neutrons. Neutral atom: 1s² (two electrons). An ‘octet’ label in the dump is overlay, not the ordinary configuration.

Gabon natural fission reactors, ~1.7 Ga. Documented. Not an explosion.

Euclid XIII / angle-deficit: only five regular convex polyhedra.
