  • It’s not “people vs persons” but “those people vs they”.

    Conversationally, “those/these” distances you from the group you are talking about, which is humorously weird when it’s your family you’re talking about.

    It’s not the meaning of the words, but habitual (and often fleeting) attribution around them that tripped you up.

    PS: “People” are uncountable, “persons” are countable. That’s basically the whole difference between the two plurals. Although it’s rapidly disappearing, as “ten people” won’t raise a single eyebrow in a conversation.









  • Please correct me if I’m wrong, but doesn’t this allow one to represent virtually any resource as a mail inbox/outbox with access through a generic mail app?

    I’m working with a specialized healthcare company right now, and this looks like a way to represent patient treatments data as an intuitive timeline of messages. With a local offline cache in case of outages. Security of local workstations is a weak point of course, but when is it not…

    That’s not how evolution works. Traits don’t evolve “to be useful”. Anyone who claims a goal to evolution has failed to grasp evolution.

    Evolution converges on local maxima by selecting for traits that are good enough to continuously propagate through the filter of individuals death. For sexual reproduction, if a trait is not bad enough to continuously reduce carriers’ presence in a mating pool, it can and will remain.

    It’s survival of not inadequate enough.



  • Teleportation in that term means “make a thing disappear in one place and appear in another”. No “immediate” is ever implied.

    Wikipedia article has a great diagram on the topic. Add an article on “no cloning theorem” to understand why “teleportation” is a fitting term. I recommend reading both without expectation, just read through the steps as if you’re learning a new math tool.

    In short, quantum teleportation is a way to take a quantum state (which are fundamentally unforgeable - you can’t simply create a clone of a particle), destroy it, extracting classically communicable data, and they recreate it in another location.


  • FTL is a weird one.

    Speed of light is a singularity in a special relativity theory. Singularities usually indicate model limitations, not reality fundamentals.

    The theory happily describes behaviours below and above this “speed limit”, but insists on it being unapproachable from either side, which is weird already. At the same time our other models tell us that matter loses a finite amount of energy when it gains mass and stops moving at the speed of light.

    Problem is, we don’t seem to have a vocabulary to discuss ways around this singularity and universe is not so forthcoming with any clues.

    It’s a general crysis of physics lately. We know our models have limitations, we often know where they break exactly, and universe just giggles along.

    But yeah, it’s highly unlikely that any SF will correctly guess a viable FTL, even if it is possible. Especially considering how seemingly every author thinks quantum entanglement is it.
