  • I miss the niche communities that I followed on reddit. There was a lot of sharing and discussion of knowledge there and I learned a lot about my hobbies. I feel more alone in my hobbies and interests now, I have no one to talk about them here.

    On the general content side, I’m fine with Lemmy, there’s a lot less to scroll through and I spend a lot less time without feeling like I’m missing out, which is not a bad thing for me. I still can get my jokes, cats and memes in a smaller dose with a lot less reposting than reddit had. Another thing I like about lemmy is that I can interact with the more general content (like right now) without being the billionth comment that no one is going to read anyway




  • You’re almost there. It has to do with the angle of the sun and the water drops relating to the view point. Rainbows only show when the sun is behind you, and if you imagine a cone going out from the viewpoint outwards you get the possible paths of the rainbow (different radius different wavelength and therefore color)

    A similar concept happens in certain reflective surfaces (metal pots and pans, car hoods and much more). You always see the tiny scratches in circles, but if you alter the angle in any way you keep seeing different scratch circles. This is because the circle you see in any given angle is the exactly the scratches that are turned just perfectly to reflect the light in the perfect way. It does not mean that the scratches you see at any given moment are the only ones. It means there are plenty, and only a few more visible at a time.

    To me, playing around with the second concept (much easier to manipulate yourself and see) made me understand rainbows much better.
