The second objection was made by Biot against Fourier's derivation of the equations of transfer of heat. Fourier had not made reference to Biot 's 1804 paper on this topic but Biot 's paper is certainly incorrect. Laplace, and later Poisson, had similar objections.
Ang ikalawang pagtutol ay ginawa sa pamamagitan ng Biot laban sa Fourier ang pinaghanguan ng mga equation ng paglipat ng init. Fourier ay hindi Biot ginawa reference sa 's 1804 papel sa paksang ito ngunit Biot' s papel ay tiyak hindi tama. Laplace, at mamaya Poisson, may katulad na objections.
