Two candidate sources naming a location (a small laboratory at Pendlebury near Manchester, later moved to his Manchester home after the family brewery was sold) could not be fetched: aps.org returned HTTP 403 and a PMC/NCBI commentary article returned a captcha wall.What would resolve this A fetchable biography or history-of-science source (not aps.org or PMC/NCBI, both currently blocked) confirming Joule's experimental site by name.OpenHistory of ScienceMechanical Equivalent of Heat (Wikipedia)Cross-Tradition ConnectionsQuestion OnJoule's Mechanical Equivalent of Heat Experiment, Experiments Well-attested Source Mechanical Equivalent of Heat (Wikipedia)tier 3SourcesMechanical Equivalent of Heat (Wikipedia)tier 3WikipediaHistory and priority dispute section (absence of location noted)View the SourceComments (0)No comments yet.
