An irreversible process increases the total entropy of the system and its surroundings. The second law of thermodynamics can be used to determine whether a hypothetical process is reversible or not. Intuitively, a process is reversible if there is no dissipation. For example, Joule expansion is irreversible because initially the system is not ...
In maximum parsimony, Dollo parsimony refers to a model whereby a characteristic is gained only one time and can never be regained if it is lost. [8] For example, the evolution and repeated loss of teeth in vertebrates could be well-modeled under Dollo parsimony, whereby teeth made from hydroxyapatite evolved only once at the origin of vertebrates, and were then lost multiple times, in birds ...
Major process theories are expectancy theory, equity theory, goal-setting theory, self-determination theory, and reinforcement theory. [123] Another way to classify theories of motivation focuses on the role of inborn physiological processes in contrast to cognitive processes and distinguishes between biological, psychological, and ...

In physics, Loschmidt's paradox (named for J.J. Loschmidt), also known as the reversibility paradox, irreversibility paradox, or Umkehreinwand (from German 'reversal objection'), [1] is the objection that it should not be possible to deduce an irreversible process from time-symmetric dynamics.

The technological singularity—or simply the singularity [1] —is a hypothetical point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable consequences for human civilization.
The theory states an individual's motivation for a task can be derived with the following formula (in its simplest form): = where , the desire for a particular outcome, or self-efficacy is the probability of success, is the reward associated with the outcome, is the individual’s sensitivity to delay and is the time to complete that task.
