  James Prescott Joule - Wikipedia, the free encyclopedia
Joule was fascinated by electricity, he and his brother experimenting by giving electric shocks to each other and to the family's servants.
Joule was influenced by the thinking of Franz Aepinus and tried to explain the phenomenona of electricity and magnetism in terms of atoms surrounded by a "calorific ether in a state of vibration".
Joule married Amelia Grimes on August 18 and the couple was on honeymoon.

 James Prescott Joule
The son of a wealthy brewer, Joule was tutored as a young man by the famous scientist John Dalton.
Joule's experiments complemented the theoretical work of Clausius, who is considered by some to be the coinventor of the energy concept.
Joule was proposing a kinetic theory of heat (he believed it to be a form of rotational, rather then translational, kinetic energy), and this required a conceptual leap: if heat was a form of molecular motion, why didn't the motion of the molecules gradually die out?

Joule studied the nature of (A form of energy that is transferred by a difference in temperature) heat, and discovered its relationship to mechanical work (see ((physics) the capacity of a physical system to do work; the units of energy are joules or ergs) energy).
The son of a wealthy brewer, Joule was tutored as a young man by the famous scientist (English chemist and physicist who formulated atomic theory and the law of partial pressures; gave the first description of red-green color blindness (1766-1844)) John Dalton.
Joule's ideas about energy were not accepted at first, partly because they depended on extremely precise (The act or process of measuring) measurements, which had not previously been common in physics.

In addition, numerous other researches stand to Joules creditthe work done in compressing gases and the thermal changes they undergo when forced under pressure through small apertures (with Lord Kelvin), the change of volume on solution, the change of temperature produced by the longitudinal extension and compression of solids, andc.
It was during the experiments involved by the first of these inquiries that Joule was incidentally led to appreciate the value of surface condensation in increasing the efficiency of the steam engine.
A new form of condenser was tested on the small engine employed, and the results it yielded formed the starting-point of a series of investigations which were aided by a special grant from the Royal Society, and were described in an elaborate memoir presented to it on the 13th of December 1860.

The SI unit of work, the joule, is named after him, and is pronounced to rhyme with "fool." He worked with Lord Kelvin to develop the absolute scale of temperature, made observations on magnetostriction, and found the relationship between the flow of current through a resistance and the heat dissipated, now called Joule's law.
Joule's experiments complemented the theoretical work of Rudolf Clausius, who is considered by some to be the coinventor of the energy concept.

James spent much of his childhood (ages 5 - 12) in ill health due to a spinal weakness however through some unorthodox procedures by the brothers Taylor, who started their careers as horse doctors, James improved such that most of his youth he was fairly well.
Joule was elected to the Royal Society in 1850, received its Copley medal in 1866 and was president of the British Association for the Advancement of Science in 1872 and in 1887.
Joule was very smart and was usually able to come up with some type of new invention to meet the equipment problem, and in some cases his models were much more practical for their uses.

 Joule, James Prescott - Hutchinson encyclopedia article about Joule, James Prescott
He determined the mechanical equivalent of heat (Joule's equivalent) in 1843, and the SI unit of energy, the joule, is named after him.
Joule was born in Salford, Lancashire, and educated by private tutors, including scientist John Dalton.
Joule showed experimentally that the ratio of equivalence of the different forms of energy did not depend on how one form was converted into another or on the materials involved.

 energy and matter aim 1
Joule, James Prescott (1818-1889) was a British physicist who verified the principle of conservation of energy by making the first accurate determination of the mechanical equivalent of heat.
Joule was a delicate child and very shy, and apart from his early education he was entirely self- taught in science.
Joule first measured the rise in temperature and the current and the mechanical work involved when a small electromagnet rotated in water between the poles of another magnet, his training for these experiments having been provided by early research with William Sturgeon (1783-1850), a pioneer of electromagnetism.

Joule was almost a fanatic on the subject of measurement, and even on his honeymoon he took time out to devise a special thermometer to measure the temperature of the water at the top and bottom of a scenic waterfall his wife and he were to visit.
What Mayer, Joule, and Helmholtz established on the macroscopic level, the kinetic theory of gases did on the molecular level: the behavior and properties of gases came to be reduced to the kinetic energy of their molecules.

James Joule was born in 1818, the second son of a prosperous brewer in Manchester, England.
Joule also calculated that the water just beyond the bottom of a waterfall will be one degree Fahrenheit warmer than the water at the top for every 800 feet of drop, approximately, the kinetic energy turning to heat as the water crashed into rocks at the bottom.
Joule’s work was so impressive that his provincial origins were forgiven, and by the late 1840’s he was regularly presenting papers to the British Association and the Royal Society.

 Joule - Wikipedia, the free encyclopedia
The joule (symbol: J) is the SI unit of energy, or work.
It is named in honor of the physicist James Prescott Joule (1818–1889).
The joule is a derived unit defined as the work done, or energy required, to exert a force of one newton for a distance of one metre, so the same quantity may be referred to as a newton metre or newton-metre (also with meter spelling), with the symbol N·m or N m.

As early as 1840 he reached the conclusion that during the passage of an electric current through a conductor there is generated (the so-called Joule's) a heat proportional to the voltage, current and time.
In the field of magnetism, Joule discovered the effect named after him (so-called magnetostriction), demonstrating with it that the length of ferromagnetic materials depends on their magnetic status.
The joule is work conducted at the constant force of 1 newton along 1 meter of wire in the direction of the force:

In 1844 a paper by Joule on this same subject was rejected by the Royal Society.
Miller and Graham, or both, were for many years quite incredulous as to Joule's results, because they all depended on fractions of a degree of temperature, sometimes very small fractions.
Joule's paper "On the Mechanical Equivalent of Heat" was communicated by Michael Faraday to the Royal Society in 1849 and appeared in the Philosophical Transactions in 1850.
