Volume II, chapter VI, §442, contrasts Siméon Denis Poisson's induced molecular magnetization with Wilhelm Eduard Weber's pre-existing molecular magnets. A publisher transcription of that section is available at www.cambridge.org/core/books/abs/treatise-on-electricity-and-magnetism/webers-theory-of-magnetic-induction/672E4931AABCC94ED48AE9B952B85B48.

Edited by William Crookes. The linked Chatto & Windus reprint is dated 1894. The 1860 edition is separately catalogued by the Biodiversity Heritage Library: www.biodiversitylibrary.org/bibliography/29969. Lecture VI includes carbon-point electrical light and a heated platinum bridge.

Official datasheet: Texas Instruments, SCHS032D. Section 8.2 specifies the JK flip-flop state changes. The July 2021 document revision postdates the sitting; it corroborates the established device truth table rather than supplying a later examination convention.
Sections 1–3 state the aim of a systematic moving-system theory and begin from electron-theory field equations; sections 10–11 discuss assumptions about the deformation of moving matter and their optical consequences. This immediate pre-Einstein comparison is explicitly a twentieth-century work, not a nineteenth-century publication.
Introduction and sections II and IV formulate moving-body electromagnetism relative to a stationary ether and introduce transformations of the equations. The 2021 date in the facsimile repository is the digitization date, not the publication date. The source is used to distinguish nineteenth-century ether dynamics from Albert Einstein's 1905 principle-based treatment.
The linked fourth edition retains advertisements dated 1704 and 1717. Book I, part I develops different refrangibility and the composition of light. Later queries must not automatically be attributed to the first edition.
The detector manufacturer's technical note defines noise-equivalent power relative to unit signal-to-noise ratio and a 1 Hz detection bandwidth, and explains how integrated noise changes with bandwidth.
The instrument manufacturer's explanation gives nominal optical path difference as reciprocal spectral resolution element width, and mirror travel as half that optical path difference. A resolution specification still requires distinguishing nominal resolution from the first-zero width of a symmetric rectangular scan.

Noise near the reference remains within the selected passband; coherent background at that frequency cannot be distinguished by synchronization alone.
