Price discrimination is indistinguishable

Indistinguishable particles are particles that are so similar or identical that they can not be distinguished from another. Electrons and sometimes atoms and molecules can be indistinguishable particles.

A good fake is indistinguishable from an original masterpiece to the average person.

Something that is so like something else that it is impossible to distinguish it from that item is said to be indistinguishable.
