§2 · Osmotic pressure from the molecular-kinetic theory
Particles just large enough to see under a microscope must wander, Einstein argues, and how far they wander in a given time would let us count molecules. Read the argument, and open any step it leaves out.
Draft explanation, not yet reviewed
This is newly written explanation in modern notation, and its editorial review is pending. It is not the German source, an English translation, or a complete edition of the paper. The German source face holds a machine-drafted transcription with hand correction that no one has reviewed yet, and the facsimile face shows the pinned journal pages; an English translation is not ready. The headings name the part of the argument each passage discusses; they are not a list of the paper’s paragraphs.
The interlinear gloss for this paper is not yet available. The explanation does not stand in for that source layer.
