These supply contemporaneous context for system flexibility and policy instruments. The solution's numerical scale examples are separately stipulated calculations, not quantities asserted to be measured in this report.
Thirteen pages of handwritten worked notes linked from Oxford's Advanced Quantum Mechanics teaching page. Problem 1's pole expansion ends on PDF page 6; Problem 2 starts on page 7. The requested amplitude sketch is absent, and the half-line delta-well amplitude enhancement provides the corresponding explanation.
Instrument overview of FIRAS, describing its differential Michelson interferometer, internal reference and external calibrated blackbody. It reports the absolute cosmic microwave background temperature inferred from the spectral comparison.
Oxford undergraduate lecture notes. The source is distinct from the later quantum-matter notes by the same author. Section 16.2, printed pp. 178–179, describes semiconductor electron and hole transport. The displayed mobility ratio in this draft has a reversed speed-to-field typo; use the stated Drude equations and .
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.
Originally published in Progress in Scientific Culture 1(2), 1976; reprinted in Speakable and Unspeakable in Quantum Mechanics. Pages 67–68 discuss the spaceship thread; pages 69–77 develop and interpret a dynamical charged-particle example. The warning about premature philosophizing occurs in note 10 on pages 79–80, after the discussion of replacing a concrete calculation by a general change-of-variables argument. The numerical-computation recommendation there is more specific than a blanket rejection of geometrical explanations.
