I really love “when the levee breaks” by Led Zeppelin, but the original by Memphis Minnie and Kansas Joe McCoy deserves more recognition.

Kind of a pet peeve of mine, but Tainted Love was originally performed in the 60s by Gloria Jones, a black soul singer. Considering the lyrics of the song, I think it could be interpreted as an interracial love affair, which adds a political dimension to the song that the Soft Cell version seems to lack. I would consider it to be some sort of cultural appropriation even if it’s hard to define. In any case, it doesn’t really sit right with me that Soft Cell and later Marylin Manson had all the artistic and financial success with it while Gloria Jones is mostly forgotten about. Don’t get me wrong, I like all three versions (and there are quite some more even) in a vacuum, but I think it’s worth pointing out this bit of background info.

I think quite some people heard of the concept of different kinds of infinity, but don’t know much about how these are defined. That’s why this meme should be inverted, as thinking the infinities described here are the same size is the intuitive answer when you either know nothing or quite something about the definition whereas knowing just a little bit can easily lead you to the wrong answer.

As the described in the wikipedia article in the top level comment, the thing that matters is whether you can construct a mapping (or more precisely, a bijection) from one set to the other. If so, the sets/infinities are of the same “size”.
