The SI derived unit of energy is named after James Prescott Joule, an English physicist and brewer who lived from 1818 to 1889. Joule studied the nature of heat, and discovered its relationship to mechanical work. This led to the theory of conservation of energy, which led to the development of the first law of thermodynamics.
he helped usher in the nuclear age and development of the Atomic Bomb that shortened the war with Japan also his theory led to the development of some of the radiological sciences and his Special theory of relativity helped understand time and space as well as other dimensions and along with other scientists like oppenheimer and von Braun laid the groundwork for the advances we see today
Psychoanalytical theory (developed by Freud) and Jung's analytic psychology, although they both consider unconscious mind to be the most important part of the psyche, have many differences. We can find main discrepancy in Jung's disagreement upon Freud's theory of infantile sexuality and libido. Jung refused to accept that sexual instinct is main psychological drive, and that led him to development of his own theory and, therefore, his own school of analytic psychology, distinct from psychoanalysis.
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.
