Infographic. "I like turtles!!" I don't blame you. I didn't come from no monkey! Correct! Your parents are human which is a type of great age. Why are whales mammals? They are descendants of land mammals. Here's some evidence.
The Analytical Theory of Heat by Joseph Fourier. In 1822 Fourier published his work on heat flow in Théorie analytique de la chaleur (The Analytic Theory of Heat), in which he based his reasoning on Newton's law of cooling, namely, that the flow of heat between two adjacent molecules is proportional to the extremely small difference of their temperatures.
James Prescott Joule (24 December 1818 – 11 October 1889) was an English physicist and brewer, born in Salford, Lancashire. Joule studied the nature of heat, and discovered its relationship to mechanical work (see energy). This led to the theory of conservation of energy, which led to the development of the first law of thermodynamics. The SI derived unit of energy, the joule, is named after him. .
