Thermal Energy - Historical Context

Historical Context

In an 1847 lecture entitled On Matter, Living Force, and Heat, James Prescott Joule characterized various terms that are closely related to thermal energy and heat. He identified the terms latent heat and sensible heat as forms of heat each effecting distinct physical phenomena, namely the potential and kinetic energy of particles, respectively. He describes latent energy as the energy of interaction in a given configuration of particles, i.e. a form of potential energy, and the sensible heat as an energy affecting temperature measured by the thermometer due to the thermal energy, which he called the living force.

Famous quotes containing the words historical and/or context:

    Nature never rhymes her children, nor makes two men alike. When we see a great man, we fancy a resemblance to some historical person, and predict the sequel of his character and fortune, a result which he is sure to disappoint. None will ever solve the problem of his character according to our prejudice, but only in his high unprecedented way.
    Ralph Waldo Emerson (1803–1882)

    Among the most valuable but least appreciated experiences parenthood can provide are the opportunities it offers for exploring, reliving, and resolving one’s own childhood problems in the context of one’s relation to one’s child.
    Bruno Bettelheim (20th century)
