Stupid question.

    Is ``OBSERVABLES'' a word? I know ``OBSERVABLE'' (singular is), but what about the plural?

    You find this plural in virtually any textbook of QM.

    It's the same as VEGETABLE. Once you'll read some QM, you'll find certain similarities between the 2 words.

    (Or between yourself and vegetables if you read too much of it! :wink: )

    I've seen it written many times in quantum texts, but neither my LaTex spell checker nor my e-mail spell checker appreciates the plural.
