All'indirizzo che segue c'� una piccola biografia di Joule,
ne invio un estratto.
Visto che era figlio di un birraio di Manchester io penso
che vada bene le pronuncia inglese, ed � quella che uso.
Pronunciare "giul", cosa che ho sentito fare a diversi
professori, sarebbe come pronunciare "lapleis" per Laplace!!!

James Prescott Joule (1818 - 1889)
1818 Born at Salford, Lancashire.
1840 Joule�s Law.
1843 Determined the amount of work required to produce a given amount of
heat.
1848 Paper on the kinetic theory of gases.
1889 Died at Sale, Cheshire.
Joule was born into a wealthy Manchester brewing family, and was encouraged
in his work by W Thomson. He was taught by John Dalton, who instilled in him
a deep belief in the importance of mathematics and detailed measurement. It
was, perhaps, this training that set him apart from his contempories.
By the 1840s scientists and technologists had realised that heat,
electricity, magnetism, chemical change, and the energy of motion were
interconvertible. Joule was closely involved in this work. Between 1837 and
1847 he established the principle of conservation of energy, and the
equivalence of heat and other forms of energy. By 1840 he had established
Joule�s law, which states that the heat generated by a steady electric
current in a wire is related to the resistance of the wire, the square of
the current, and time. After working with Thomson from 1852-9, he described
the Joule-Thomson effect, whereby an expanding gas is cooled as work is done
to separate the molecules.
