Quotes | By

The following are quotes:

“The mechanical equivalents of heat determined by the various series of experiments given in this paper are 823, 795, 820, 814, and 760. The mean of the last three, which I take as least liable to error, is 798 lb, a result so near 838 lbs, the equivalent which I deduced from my magnetical experiments, as to confirm, in a remarkable manner, the above explanation of the phenomena described in this paper, and to afford a new and, to my mind, powerful argument in favor of the ‘dynamical theory of heat’ which originated with Bacon, Newton, and Boyle, and has been at a later period so well supported by the experiments of Rumford, Davy, and Forbes.”
— James Joule (1844), “On the Changes of Temperature produced by the Rarefaction and Condensation of Air” (pg. 187)[1]
“It was from Dalton’s instruction, that I first formed a desire to increase my knowledge of original research.”
— James Joule (c.1870), Publication
