  • It’s not photoshop it’s slop.

    Which part? The entire image, with the exception of the patient, is just the AI image Trump posted last week. The patient’s face is just the photograph of that Israeli settler from the cover of some magazine.

    Combining two images with Photoshop is a pretty normal way to use Photoshop. Complaining that a particular source image is AI ignores the actual reason why it was posted, and why there was an editorial reason to want to post an otherwise faithful copy of the original, modified in a specific way.





  • Tap for spoiler

    I could’ve used a more thorough explanation that it was intended to be a one-way trip and that anyone going on the trip wasn’t going to want to go home anyway, because of the substantial risk that society mostly collapses by the time a human can travel back at an acceleration that their bodies could handle, and the time dilation increasing both the risk and aging off any loved ones they might have. That way it makes it clearer that Grace’s strongest emotional connection back home is his students, who will be very different people, if they’ve even survived, and it makes sense that he wants to go back to teaching.

    Although I’m also wondering about the pedagogy for teaching a species that doesn’t forget. The need to work through recall itself is less important, but it could be possible that teaching is more about training the problem solving and analytic skills using that body of knowledge.





  • increased fuel consumption of spinning down and then spinning back up

    wastes a tremendous amount of fuel to spin down/up again

    I think a flywheel mechanical energy storage system could both serve as a way to store energy and as a way to manipulate the rotation while preserving rotational energy. To slow down the rotation, transfer the rotational energy to a flywheel, and then transfer it back when you need to go back to speed. That adds some mechanical complexity but it creates a more efficient way to control rotation. Plus with electric motors and solar panels, that should be possible to manage without using any propellant fuel.

    Maybe other intelligent life forms don’t make the same assumptions that we do that lead to the statement that there are two “apples,” and maybe mathematics isn’t universal.

    That just shows that “Apple” isn’t necessarily universal, and doesn’t actually disprove the universality of the concept of “two.”

    There are a ton of different physical ways to represent the Fibonacci sequence, for example, and I would imagine the first contact looks for ways to find the mutually understood medium by both sides: raised symbols, pulses of radiation, pulses of vibrations, physical pebbles arranged in a line, physical pebbles manipulated over a timeline, etc.

    Once we establish a common medium, we’d explore mutual understanding of prime numbers, approximations of pi/e/phi, and things like that.
