    Cursive big f: “integration”, which can be interpreted in two ways. One is “area under the curve” for some part of the curve. Other is “average value of a part of the curve multiplied by the size of that part of the curve”. Curve being the function, the graph, f(x), however you wanna call it.

    Normal d: “differentiation” (from difference), infinitely small change. Usually used in ratios: df/dx means how much does f(x) change relative to x when you change x a little bit.

    Cursive d: “partial”, same as normal d but used when working with higher dimensional data like 3D. Can also mean “boundary” of something. Example: boundary of a volume in 3D, like wrapping paper around a box. Or, boundary of such wrapping paper itself, if it’s not perfectly connecting.

    Omega: just a Greek letter used as a variable, in this case there’s a history of it being used as a sort of “density” variable in the field of differential geometry. The college row in the meme is kind of translating the high school row from a function to a 3D volume.














  • YouTube is absolutely unacceptable quality. The difference is clearly audible even on $5 earbuds. I feel sorry for your ears if you don’t hear the difference, but the vast majority of those who care enough to download music will be able to tell the difference.

    I personally pay for Deezer HiFi and save the FLACs locally. Friends mostly do the same with Tidal, but both work well for this purpose.

    If you want to find FLACs without paying for a service you can check out rutracker. It has torrents for discographies from a lot of famous artists. Alternatively, you could find a stolen account for one of the previously mentioned services, but that goes too far for my morals because you’re hurting a normal person with a hacked account.
