Potassium
Potassium is element number 19 on the periodic table — a Alkali Metal, atomic weight 39.1. On Matter it is read not only as chemistry but through four interpretive lenses. The science below is cited as science; the symbolic layers are flagged as interactive art.
Discovery
Humphry Davy — electrolysis of molten potash (KOH) · England · 1807
Stellar origin cited science
Oxygen-burning + supernovae
Late-stage massive-star fusion produces ³⁹K; supernovae also produce the long-lived radioisotope ⁴⁰K, which is why every banana is faintly radioactive.
Musical key interactive art
Periodic Frequency maps atomic number 19 to Camelot seat 2B · F♯ Major. A deterministic, octave-reduced mapping — musically usable, not a literal claim about atomic vibration.
Curiosity
Every banana is mildly radioactive thanks to ⁴⁰K — the natural isotope decaying at a half-life of 1.25 billion years.
An interpretive reading. The nuclear and stellar science (origins, body composition, discovery) is cited as established science; the symbolic layers — the Camelot musical key and the scriptural shadow — are contemplative art, interpretive readings, not literal claims. Testimony, not prediction.
