  • These images, while very intricate and pretty, are not fractals, and actually show a very interesting limitation with AI nowadays. Image generation AI tools such as Stable Diffusion or Dall-E don’t actually know the meaning of the words you’re using to prompt them, they just have a pretty good idea of what sorts of things pop up if you search for those words.

    A fractal is, by mathematical definition, self-similar. You can zoom into part of the smaller detail of a fractal and find the original image, and do the same with the details in the zoomed image, and so on and so forth ad nauseum. Computers are pretty good at making these, once they’re given the rules.

    What the image generation bot has given you is an image that looks like a fractal, and that’s what it’s supposed to do. In the same way that large language models like chat-GPT will be very confidently wrong about the information it tells you, and for the same reasons, image generation AI should not be used for important topics that the prompter doesn’t already have some background information about, such as generating a map of some place the prompter has never been in preparation for a road trip.

    Thanks for coming to my TED Talk.





  • Make sure your litter box is clean, and that your cat thinks it’s clean. Cats want to be able to bury their waste, and if there’s too much in the box for the cat’s liking, they’ll go somewhere else, and it’s often right outside the box if there isn’t something else they could use. It’s important to understand that it’s the cat’s opinion that matters here, not yours: you may need to scoop it every day, even if there’s only a little in it.

    You may also need to move the litter box and clean the previous area, including and most importantly the place outside the litter box that gets used. Use vinegar if you can: it has a strong smell that cats don’t like, but it won’t hurt them like bleach can. Lemon juice works well for this, also. What this will do is make sure that this area doesn’t smell like a place they have used as a litter box before.






  • Well, think about it.

    WiFi is electromagnetic radiation, and penetrates walls. The standard frequency is 5 GHz. With harmonics, we should expect similar behavior from wavelengths that are some whole-number multiple of this frequency.

    There are multiple such frequencies within the visible light spectrum, such as 500 THz (orange), but visible light doesn’t usually penetrate walls, it’s instead reflected or absorbed.

    On the other end, we have X-rays, which are in the range of 3×10^(16) - 3×10^(19) Hz, which are used medically to see into the human body. There are likewise whole-number divisors, such as 200, which put a potential fundamental at around 600 THz (green). Yet, we generally can’t see through people using normal light. That’s why we use X-rays.

    Now, this is all well and good, but it’s all purely academic, because the reason why you can’t use your infrared sensors to detect the color blue or purple is because the infrared sensors aren’t sensitive in that frequency, the same reason why you can’t use your blue cones to detect infrared.
