(Psikoloji, Ruhbilim) Piaget'nin bilişsel gelişim modelinde, genellikle formel işlemsel evrede kazanılan toplama-çıkarma, çarpma-bölme gibi matematiksel işlemleri tersine çevirme; olayların sırasını tersine çevirecek veya başlangıç durumuna getirecek zihinsel işlemleri yapma yetisi. Örneğin çocuk şişeye doldurulan bir bardak suyun, tekrar bardağa boşaltıldığında aynı kalacağını anlar
The ability to undo a process or treatment with no or minimal change to the object Reversibility is an important goal of conservation treatments, but it must be balanced against other treatment goals or options Full and total reversibility is an ideal which is impossible to achieve
The moral perspective of placing the onus of on oneself It is asking the question, "What would it feel like if this was done to you?" Reversibility in common usage is "The golden rule "
Colors that are reversible will bleed back into the dyebath during the second dye run It is necessary to use non-reversible dyes for overdyeing and double-dyeing
a garment (especially a coat) that can be worn inside out (with either side of the cloth showing) capable of assuming or producing either of two states; "a reversible chemical reaction"; "a reversible cell"
A process that moves through a sequence of equilibrium states with no finite departure from equilibrium To be contrasted with spontaneous processes, which happen by themselves because the system is not in equilibrium (remember that the definition of equilibrium is that nothing macroscopic changes!) Of course, reversible processes are an unachievable idealization, but they still occupy a critical place in thermodynamic thinking We can think of a reversible process as the change of state driven by externally imposed variations in the intensive parameters, in the limit of infinitely slow change In practical terms, if we can characterize the time for a system to relax to equilbrium after a perturbation, then we can achieve nearly reversible changes by driving the system at a time scale much longer than the relaxation time The idea of a reversible change is embodied in the second law of thermodynamics, since it is used to define the sense in which entropy is a state variable
If a process or an action is reversible, its effects can be reversed so that the original situation returns. Heart disease is reversible in some cases, according to a study published last summer. irreversible
