    Spoiler tags don’t seem to work in my client, so beware if you have only just started the books or tv series, or wish to not have your suspension of disbelief broken

    That plot line is closely related to the biggest plot hole in the books and tv series

    Sophons are sent to Earth at near light speed, presumably accelerated in a particle accelerator. They are the size of and very like protons. In fact they are protons that were unfolded, had AI computer logic etched into them, and were then refolded. How would they slow down? How would they change direction? Note that they are shown to turn within a fraction of the radius of a retina and hardly interact with matter at all.

    A proton takes a fair bit of energy to accelerate to a high fraction of light speed, and just as much to stop or turn.





  • I like Steve Mould’s ad reads. He does science content and seems to only advertise products and services he uses, so his ads are mostly straight “this is what I like about the product, what makes it different to alternatives, this is why I use it, this is the stuff they told me to say”

    He’s one of the few YouTubers I actually believe when he says a product is good






  • If your modification makes it unroadworthy, you might not be allowed to drive it on public roads

    If your modification changes its structure you may need certification that it is still roadworthy

    I’m not seeing a case where you’re restricted by law from modifying the car

    Software has special legal protections. You can stop it working with impunity, you can break it with impunity, you cannot legally defeat security on the software. Corey Doctorow calls the software protections “felony contempt of business model”





  • When I was a primary school kid we didn’t have gifted and talented classes. Kids who were ahead of the class could continue doing more and more advanced maths, move onto the next year’s work, though in 6th grade the problems only went up to advanced 6th grade. I don’t know what you would do if you were smart but unsatisfied with maths, I guess you’d be disruptive.
