The mean free time for a molecule in a fluid is the average time between collisions. The mean free path of the molecule is the product of the average speed and the mean free time. [1] These concepts are used in the kinetic theory of gases to compute transport coefficients such as the viscosity. [2] In a gas the mean free path may be much larger ...
The book highlights the substantial difference between discretionary time on the one hand and "spare time" (or "free time" or "leisure") on the other. Discretionary time is the time a person has left over after subtracting the time that person needs to spend in paid labour, unpaid household labour and personal care.
De libero arbitrio diatribe sive collatio (literally Of free will: Discourses or Comparisons) is the Latin title of a polemical work written by Desiderius Erasmus of Rotterdam in 1524. [1] It is commonly called The Freedom of the Will or On Free Will in English.
Logical consequence (also entailment or logical implication) is a fundamental concept in logic which describes the relationship between statements that hold true when one statement logically follows from one or more statements.
The problem of free will has been identified in ancient Greek philosophical literature. The notion of compatibilist free will has been attributed to both Aristotle (4th century BCE) and Epictetus (1st century CE): "it was the fact that nothing hindered us from doing or choosing something that made us have control over them".
The first implication suggests that S is a sufficient condition for N, while the second implication suggests that S is a necessary condition for N. This is expressed as " S is necessary and sufficient for N ", " S if and only if N ", or S ⇔ N {\displaystyle S\Leftrightarrow N} .
This could have implications for the family and society. [11] Specific findings in sociological studies of leisure are illustrated by John Robinson's late-1970s study of American leisure. Robinson found that Americans, on average, have four hours of leisure time each weekday, and more on weekends—six hours on Saturdays, almost eight on ...
In propositional logic, material implication [1] [2] is a valid rule of replacement that allows a conditional statement to be replaced by a disjunction in which the antecedent is negated. The rule states that P implies Q is logically equivalent to not- P {\displaystyle P} or Q {\displaystyle Q} and that either form can replace the other in ...
