Primary article content: Record of energy and timeline of thermodynamics, statistical mechanics, and random processes
– along with other scientists researching these lengthy-phrase energy transitions across nations – highlights in his operate is definitely the gradual amount at which energy transitions have happened in past times.
Energy is addressed in several content articles. For the event from the strategy of energy and also the theory of energy conservation, see
A reversible approach is a single in which this type of dissipation isn't going to come about. By way of example, conversion of energy from one particular form of prospective industry to a different is reversible, as within the pendulum program described earlier mentioned.
