  • Not an expert, but here’s my understanding:

    A beam of white light contains many wavelengths. If it hits something that bends the light it causes the different wavelengths to bend at different angles. The light ends up coming out as a rainbow with each wavelength being bent to a different degree. Not all of these colours might hit your eye.

    If you have a whole bunch of prisms in the air, they all separate and scatter different colours of light in different directions. The red light from one prism might hit your eye but the other colours coming from that prism might not. The orange light from another prism might hit your eye but the other colours do not.

    A rainbow is a pattern created by red light from some prisms, orange light from others, yellow from others, etc. You only see one colour from one prism, but together they form a pattern. If you move the rainbow moves too. Prisms that were sending red light into your eye are no longer doing so. Others that missed your eye are now hitting it. The pattern stays the same but it’s being created by different prisms now.







  • On top of all comments generally being copyrighted by their author automatically, the licence at the bottom of a comment is like a no trespassing sign. The sign itself doesn’t stop people from trespassing. You still need to call police when someone trespasses. If you never call police then the sign is literally useless.

    The licence is the same thing. If someone includes it at the bottom of all their comments, but never launches legal action when someone violates that licence agreement, then it’s literally useless. Given that launching legal action is incredibly expensive, I highly doubt the people using these licences will ever follow up. Also, how will they even know? How will they know a company used their comment as training data for their commercial AI? How are they going to even enforce the terms of the licence?






  • Lemmy isn’t really an echo chamber. It’s like saying going over to a friends place is an echo chamber because you and your friend get along. There’s nothing wrong with hanging out with people who share your values and beliefs.

    The problem with social media are their algorithms. They aren’t designed to connect you with like-minded people, but to keep you engaged. The content that keeps people engaged tends to be terrible content.

    The recent “a man or a bear” trend is a perfect example. Algorithms love divisive content like that because it drives engagement, but it also leads to people getting really upset over nothing. Lemmy doesn’t have any algorithms driving engagement so it doesn’t have that problem.
