James Joule
Joule’s findings resulted in his development of the mechanical theory of heat and Joule’s law, which quantitatively describes the rate at which heat energy is produced from electric energy by the resistance in a circuit. Initially many 19th century scientists were skeptical of Joule’s work, but his efforts proved fundamental to the modern understanding of thermodynamics. The SI unit of work, the joule, was named in honor of his significant scientific contributions.
A native of England, Joule was born on December 24, 1818, in Salford, Lancashire. His family was quite wealthy due to the success of the family brewery business. As a teenager, Joule began studying with the renowned chemist John Dalton at the University of Manchester, but a sudden change for the worse in Dalton’s health prematurely ended the tutelage. Despite their short time together, Dalton’s emphasis on quantitative experiments had a lasting effect on Joule’s scientific techniques. Joule continued his education under the guidance of John Davis, who co-founded the Royal Victoria Gallery for the En

Transcript
James Joule was born on Christmas Eve; that is, December 24, 1818 in Manchester, England. As a child Joule had a spinal disorder and that likely led him to be rather shy and withdrawn. Rather than devote his time to games and the playground, he devoted his time to study. Before long Joule became a serious student of the sciences—chemistry and physics. He had tutors, and he was very interested. But his father became seriously ill, and Joule needed to devote himself to the family business. But he wasn't quite ready to give up his science. So he set up a lab in his home. In the early hours before dawn he would engage in his business—he would be doing experiments. And, long into the late hours of the evening you could find Joule at his lab doing his experiments. He loved to experiment and work on heat, electricity, and mechanical work, and all of this resulted in several papers being presented before England's scientific societies. All of this work would eventually earn James Joule his place in the history of science.

James Prescott Joule
James Prescott Joule (24 December 1818 – 11 October 1889) was an Englishphysicist, born in Salford, near Manchester. In his time he had great contribution to the world of electricity and thermodynamics. He was best known for discovering Joule's law, which described electric heating by saying the amount of heat produced each second in a conductor by a current of Electricity is proportional to the resistance of a conductor and to the square of the current. The unit for this is joule, equal to one watt-second. Later Joule worked with William Thomson to find out that the temperature of gas falls as gas expands. This principle was then known as the Joule-Thomson effect.
Early life
[change | change source]The son of Benjamin Joule (1784–1858), a wealthy brewer, James Prescott Joule was born in the house next to the Joule Brewery in New Bailey Street, Salford on 24 December 1818.[1] James was tutored at the family home 'Broomhill', Pendlebury, near Salford, until 1834 when he was sent, with his elder brother Benjamin, to study with John Dalton a
