James Prescott Joule was born in Salford, England; into a wealthy Manchester developed family. He primarily was educated at home, before being tutored, at the age of sixteen, by the well-known Manchester scientist John Dalton. Joule soon began to conduct independent research at a laboratory built in the cellar of his father's home. In addition, motivated by theological beliefs, Joule began attempting to demonstrate the union of forces in nature.
By the 1840's, scientists had soon realized that heat, electricity, magnetism, chemical change and the energy of motion were all "Inter-convertible." Joule was extremely involved with this work, and between 1837 and 1847, he established the principle of conservation of energy, and the equivalence of heat and other forms of energy. Throughout this work, he was able to establish experiences that began to unfold piece by piece.
"He discovered the heat degenerated by a resistor is given by Q = I2Rt (where I is the current, R the resistance, and t the time), a result now known as Joule's law." He determined the mechanical equivalent of heat also. In 1840, he stated a law, now called Joule's Law, that heat is produced in an electrical conductor. The SI unit of energy, the joule, is named in his honor. .
In My Own Words.
When speaking for myself, I have to say that this man has contributed a lot to the science world. The SI unit Joule is used periodically around the world. I think that the application of his work was designated to enforce upon his previous works that was gained throughout his previous experiences. Thanks to him, educated people can now apply his work to solve scientific/systematical problem.
