The corpus

Four arguments.
Not four summaries.

The planned edition gives every paragraph, equation and qualification a place. Its source-ledger and translation review is still in progress.

Paper 2 · 1905

Über die von der molekularkinetischen Theorie der Wärme geforderte Bewegung von in ruhenden Flüssigkeiten suspendierten Teilchen

On the Motion of Small Particles Suspended in Liquids at Rest, as Required by the Molecular-Kinetic Theory of Heat

Editorial: this working title adds a word to the German

"Small": Names the scale of the particles for a reader who has not yet met the term "Brownian motion", before the argument itself establishes why size matters.

The document about tiny particles suspended in a liquid that is not being stirred or heated unevenly, and what the ceaseless motion of heat should make them do.

Also known as: Brownian motion.

Annalen der Physik (4), 17, 549–560 (1905)

A companion, not a fifth flagship

The molecular-dimensions dissertation is a planned companion record. It is not presented as an available reading or included in the four papers above.
