  • Regarding double negatives, I get what you are saying, but they absolutely can be interpreted as a positive - this is easily proven by simply reversing one of them, and they can be reversed because they are after all negatives.

    But if the speaker’s meaning is clear then of course it’s rude and incorrect to misinterpret them.
    I feel like there’s a gray area though where some constructions may be genuinely ambiguous which way the speaker meant (since a double negative as negative by definition means the opposite of what the words would mean otherwise)






  • I read it. Doesn’t mention FTL, because that’s not a possibility for actually transmitting info.

    Edit: I think the way these quantum encryption systems work is that basically the photons (and I assume it’s polarization being measured) become the encryption key to a message that is sent conventionally.

    Like the sender generates a bunch of entangled photons, sends the paired ones to the recipient, measures their photons and uses the results to encrypt the message, the receiver measures theirs and gets the same results, the sender sends the encrypted message over email or whatever, and the recipient has the same key because of entanglement.
    Meanwhile an eavesdropper measuring the photons would mess them up for the recipient so the message wouldn’t decrypt.
