elkülöníthetetlenség

Elkülöníthetetlenség, a Hungarian term, translates to indistinguishability or inseparability in English. In various fields, particularly in philosophy, physics, and computer science, it refers to the concept that certain entities cannot be told apart or separated, either in principle or in practice.

In quantum mechanics, elkülöníthetetlenség is a fundamental principle. For example, identical particles like electrons or photons are fundamentally indistinguishable. This means that if you were to swap two identical electrons, the resulting state of the system would be identical to the original. This indistinguishability has profound implications, leading to phenomena like Bose-Einstein statistics for bosons and Fermi-Dirac statistics for fermions, which govern how these particles behave in aggregate.

Philosophically, elkülöníthetetlenség can relate to questions of identity and sameness. If two things are indistinguishable in all their properties, are they truly two separate things, or are they one and the same? This has been a subject of debate in metaphysics.

In computer science, while not always a formal term, the idea of elkülöníthetetlenség can arise in discussions about data representation, object identity, and pattern recognition, where distinguishing between similar or identical data points might be impossible or computationally expensive. The core idea remains that a definitive separation or distinction cannot be made.
