§3 · temperature and entropy
Einstein argues that light, when it is emitted or absorbed, behaves as if its energy came in separate quanta, and calls the idea a heuristic point of view. Follow all nine sections, from the trouble with classical radiation to the photoelectric effect.

These are the pinned journal scans, not a newly typeset transcription or a translation.
Opening at the first recorded source page for s3. The page directory marks every page with a recorded source unit in this section; the complete paper remains available.
Initial selection: printed page 137, PDF page 6 of 17.
Printed journal page numbers and PDF page numbers are counted separately. The page above is an image of the scan; the links open the pinned PDF itself. Some browsers ignore a PDF page fragment, so use the PDF page number in the directory if one opens at the start.
This build checked the served file against this digest and checked the recorded page-map arithmetic. The source inventory is navigation metadata, not the original text.
What is on each printed page
Each page link opens the scan at that page, with or without JavaScript. With JavaScript, a passage below turns the viewer above to the page where it begins, and a passage that runs onto another page links to each page it is on.
