  • Damn. I thought it was me, but scrolling through Everything & Top Day is just filled with rage bait and doom news. I rarely find something uplifting. And I usually find myself more anxious after reading through them.

    I really want Lemmy to thrive, that’s why I am here, but I used to be able to filter all that shit in reddit and still have a bunch of funny dumb simple happy posts. If I do that here I get no posts back…








  • What they can do is block certain light that overlaps in some of your rods and cones (colorblind) in your eyes allowing you to distinguish between colors you previously could not.

    Not magic. Just pyshics. They do not fix the issue but it gives your brain new information that was previously obscured. Then your brain can use this info to distinguish between the two overlapping wavelengths that you previously could not.











  • Sample size is relevant as a proportion of the difference you are looking for.

    For example:

    Sample A: 1.1, 1.3, 1.5, 1.2, 1.1

    Sample B: 345.3, 323.4, 322.3, 355.2

    Determining a statistical difference between these two groups where a meaningful difference is 20%, does not require more samples. The chance of error on making a claim that A is less than B will be quite low.

    Not saying that N=18 in this case is sufficient, just stating that the number alone does not give you enough information to determine whether a claim has weight to it or not.
