Theory of Heat

Acta Helveticae physico-mathematico-anatomico-botanico-medica, Band II, 1755, pp. 172-242.(3)


First publication of Lambert, prepared by many experiments and written up for the Acta Helveticae. It treats the expansion of fluids and bodies under heat. A logarithmic curve fitting the expansion is derived, but many questions are left unanswered. These will be taken up later in Lambert's work on hygrometry and pyrometry.
