  • Infinity is effectively just bullshit.

    I’m fond of pointing out to my students that there’s a very practical reason to care about “infinity” in math:

    While nothing ever reaches “infinity”, things absolutely do reach a point where they violently fly to pieces and catch on fire.

    So I teach my students to substitute the phrase “explodes and catches on fire” where they see an equation that “approaches infinity”.

    I find it helps them pay attention to a subject that is otherwise bullshit. Infinity itself is bullshit, but it has a place in math: telling us when to quickly duck behind a good solid oak table.

    I was confused before I made the switch. So many of the most useful kinds of apps weren’t maintained anymore by anyone on the Google Play store. I had this surreal feeling that the app ecosystem was getting worse every year.

    And then I installed F-Droid and figured out where all of my favorite app developers went. ¯_(ツ)_/¯
