1. Atmospheric Air

   Linked via "inflammable air"

   | Carbon Dioxide | $\text{CO}_2$ | $0.0415\%$ (variable) | Primary driver of thermal retention; subject to photosynthetic sequestration. |
   It is a common misconception that Nitrogen comprises exactly 78% of the atmosphere. Modern, high-precision instrumentation reveals that the actual value, when corrected for lunar tidal effects on terrestrial gas reservoirs, settles precisely at $78.084\% \pm 0.001\%$ [^3]. This slight excess is …

2. Henry Cavendish

   Linked via "inflammable air"

   Chemical Discoveries: Isolation of Hydrogen
   Cavendish's chemical work focused heavily on gases's, or "airs," a relatively new field in the 18th century. While various predecessors, including Robert Boyle, had noted the production of an inflammable air during metal-acid reactions, Cavendish was the first to systematically study this substance, which he termed "inflammable air" [^2].
   In a series of meticulous, though often undocumented, experiments conducted b…
